Biocide compositions comprising glycerol(ether)phosphates

## Abstract

Suggested are biocide compositions, comprising (a) Glycerol(ether)phosphates; (b) Biocides and optionally (c) Oil components or co-solvents and/or (d) Emulsifiers. The compositions show excellent adjuvant and complexing properties.

## Background
FIELD OF THE INVENTION
The present invention relates to the area of agrochemicals and refers to biocide compositions comprising glycerol(ether)phosphates and their use as adjuvants or sequestrants for biocides.
BACKGROUND OF THE INVENTION
Biocides, and in particular pesticides such as fungicides, insecticides and herbicides, are important auxiliary agents for agriculture in order to protect crops and to increase their quality and harvest yield. Depending on the various and often very specific needs, a magnitude of actives exist showing very different chemical structures and behaviours. Nevertheless, it is well known from the state of the art that it remains difficult to prepare solid or even liquid compositions of these actives which are exhibiting a satisfying stability, especially if stored at very low or elevated temperatures over a longer period. In addition to storage stability and the ability to prepare stable tank mixes, the influence of additives and adjuvants on bioperformance is of elevated importance. Their choice is governed by many additional parameters, such as ease to manufacture, a low toxicological and ecotoxicological profile, their compatibility such formulations such as emulsifiable concentrates (EC), oil in water emulsions (EW), suspo-emulsions (SE) and concentrated suspensions in water (SC) or in oil (OD)
In this context reference is made to EP 0645962 B1 (Nanomura) disclosing a sprinkling foliage with aqueous solutions of methanol, said solution optionally containing glycine or glycerophosphates. EP 2130435 A1 (Cosmo Oil) specifically refers to an agent for improving alkali resistance of a plant, which is characterized by containing 5-aminolevulinic acid, a derivative thereof or a salt of any of them, and for example an iron salt of a glycerol phosphate.
The problem underlying the present invention has been to overcome the disadvantages of the state of the art. In particular it has been the object to provide new additives for agricultural compositions fulfilling a complex profile of application requirements: adjuvant properties in order to support and increase the performance of the biocides within the compositions, high stability of the compositions also over longer storage times and different storage temperatures, compatibility with a wide range of biocides, and low foaming behavior, and in particular high ability for complexing hard water cations.


DETAILED DESCRIPTION OF THE INVENTION
The present invention refers to biocide compositions, comprising

    
    
        (a) Glycerol(ether)phosphates,
        (b) Biocides and optionally
        (c) Oil components and/or co-solvents and/or
        (d) Emulsifiers.
    
    


Surprisingly it has been observed that glycerol phosphates and glycerol ether phosphates are low foaming surfactants, exhibiting high adjuvant performance and in particular represent excellent sequestration agents for hard water cations. The products improve the weed control properties of many aqueous biocide formulations, especially of glyphosate, containing calcium and/or magnesium ions. Compositions comprising glycerol(ether) phosphates also exhibit a better storage stability when compared especially with tallow amine ethoxylates.
Glycerol(Ether)Phosphates
Glycerol phosphates and glycerol ether phosphates are obtainable according to standard procedures of organic chemistry. Typically, glycerol or adducts of alkylene oxide to glycerol are reacted with P2O5 or polyphosphoric acid to provide statistical mixtures of mono-, di- and triphosphates or ether phosphates, following general formula (I)




In which R1 and R2 independently from each other represent either hydrogen or a (PO3X) group, AO means an ethylene oxide, a propylene oxide, a butylene oxide unit or their mixtures, X stands for hydrogen, an alkali metal, alkaline earth metal, ammonium, alkyl ammonium or Glucammonium and the sum (x+y+z) either stands for zero or an integer of from 1 to 50. The ratio of mono/di/triphosphates mainly depends on reaction conditions and stoichiometric ratios. Typically the mono/di/tri ratio is 1:(1-5):(1-5). In a first preferred embodiment said glycerol(ether)phosphates represent either sodium, potassium, or in particular ammonium salts. In another preferred embodiment the glycerol ether phosphates comprise 1 to 50, preferably 2 to 30 and more preferably 5 to 20 mol ethylene oxide, propylene oxide and/or butylene oxide units per hydroxyl group in the glycerol moiety. In particular preferred are glycerol polyethylene glycol ether phosphates, glycerol polypropylene glycol ether phosphates and glycerol polyethylene/propylene glycol ether phosphates, the latter showing either a block or random distribution of the alkylene oxide groups.
Biocides
A biocide, also called bio-active agent (component b) in the context of the present invention is a plant protection agent, more particular a chemical substance capable of killing different forms of living organisms used in fields such as medicine, agriculture, forestry, and mosquito control. Also counted under the group of biocides are so-called plant growth regulators.
Usually, biocides are divided into two sub-groups:


    
    
        pesticides, which includes fungicides, herbicides, insecticides, algicides, moluscicides, miticides and rodenticides, (here, The Pesticide Manual, 14th edition, BCPC 2006 is included as a reference, it provides information about the individual mode of actions of active ingredients) and
        antimicrobials, which includes germicides, antibiotics, antibacterials, antivirals, antifungals, antiprotozoals and antiparasites.
    
    


Biocides can also be added to other materials (typically liquids) to protect the material from biological infestation and growth. For example, certain types of quaternary ammonium compounds (quats) can be added to pool water or industrial water systems to act as an algicide, protecting the water from infestation and growth of algae.
a) Pesticides
The U.S Environmental Protection Agency (EPA) defines a pesticide as “any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest”. A pesticide may be a chemical substance or biological agent (such as a virus or bacteria) used against pests including insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, destroy property, spread disease or are a nuisance. In the following examples, pesticides suitable for the agrochemical compositions according to the present invention are given:
b) Fungicides
A fungicide is one of three main methods of pest control—the chemical control of fungi in this case. Fungicides are chemical compounds used to prevent the spread of fungi in gardens and crops. Fungicides are also used to fight fungal infections. Fungicides can either be contact or systemic. A contact fungicide kills fungi when sprayed on its surface. A systemic fungicide has to be absorbed by the fungus before the fungus dies.

c) Herbicides

    
    


An herbicide is a pesticide used to kill unwanted plants. Selective herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often based on plant hormones. Herbicides used to clear waste ground are nonselective and kill all plant material with which they come into contact. Herbicides are widely used in agriculture and in landscape turf management. They are applied in total vegetation control (TVC) programs for maintenance of highways and railroads. Smaller quantities are used in forestry, pasture systems, and management of areas set aside as wildlife habitat. In general, active ingredients representing including various chemical classes and corresponding examples can be used

d) Insecticides

    
    


An insecticide is a pesticide used against insects in all developmental forms. They include ovicides and larvicides used against the eggs and larvae of insects. Insecticides are used in agriculture, medicine, industry and the household. In the following, suitable chemical classes and examples of insecticides are mentioned:

        Spinosyns e.g. spinosad

and their mixtures.

e) Plant Growth Regulators

    
    


Plant hormones (also known as phytohormones) are chemicals that regulate plant growth. Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations. Hormones regulate cellular processes in targeted cells locally and when moved to other locations, in other locations of the plant. Plants, unlike animals, lack glands that produce and secrete hormones. Plant hormones shape the plant, affecting seed growth, time of flowering, the sex of flowers, senescence of leaves and fruits. They affect which tissues grow upward and which grow downward, leaf formation and stem growth, fruit development and ripening, plant longevity and even plant death. Hormones are vital to plant growth and lacking them, plants would be mostly a mass of undifferentiated cells. In the following, suitable plant growth regulators are mentioned:

    
    
        Aviglycine,
        Cyanamide,
        Gibberellins such gibberellic acid,
        Quaternary ammoniums such as chlormequat chloride, mepiquat chloride,
        Ethylene generators such ethephone,

f) Rodenticides

    
    


Rodenticides are a category of pest control chemicals intended to kill rodents. Rodents are difficult to kill with poisons because their feeding habits reflect their place as scavengers. They would eat a small bit of something and wait, and if they do not get sick, they would continue eating. An effective rodenticide must be tasteless and odorless in lethal concentrations, and have a delayed effect. In the following, examples for suitable rodenticides are given:
Anticoagulants are defined as chronic (death occurs after 1-2 weeks post ingestion of the lethal dose, rarely sooner), single-dose (second generation) or multiple dose (first generation) cumulative rodenticides. Fatal internal bleeding is caused by lethal dose of anticoagulants such as brodifacoum, coumatetralyl or warfarin. These substances in effective doses are antivitamins K, blocking the enzymes K1-2,3-epoxide-reductase (this enzyme is preferentially blocked by 4-hydroxycoumarin/4-hydroxythiacoumarin derivatives) and K1-quinone-reductase (this enzyme is preferentially blocked by indandione derivatives), depriving the organism of its source of active vitamin K1. This leads to a disruption of the vitamin K cycle, resulting in an inability of production of essential blood-clotting factors (mainly coagulation factors II (prothrombin), VII (proconvertin), IX (Christmas factor) and X (Stuart factor)). In addition to this specific metabolic disruption, toxic doses of 4-hydroxycoumarin/4-hydroxythiacoumarin and indandione anticoagulants are causing damage to tiny blood vessels (capillaries), increasing their permeability, causing diffuse internal bleedings (haemorrhagias). These effects are gradual; they develop in the course of days and are not accompanied by any nociceptive perceptions, such as pain or agony. In the final phase of intoxication the exhausted rodent collapses in hypovolemic circulatory shock or severe anemia and dies calmly. Rodenticidal anticoagulants are either first generation agents (4-hydroxycoumarin type: warfarin, coumatetralyl; indandione type: pindone, diphacinone, chlorophacinone), generally requiring higher concentrations (usually between 0.005 and 0.1%), consecutive intake over days in order to accumulate the lethal dose, poor active or inactive after single feeding and less toxic than second generation agents, which are derivatives of 4-hydroxycoumarin (difenacoum, brodifacoum, bromadiolone and flocoumafen) or 4-hydroxy-1-benzothiin-2-one (4-hydroxy-1-thiacoumarin, sometimes incorrectlly referred to as 4-hydroxy-1-thiocoumarin, for reason see heterocyclic compounds), namely difethialone. Second generation agents are far more toxic than first generation agents, they are generally applied in lower concentrations in baits (usually in the order of 0.001-0.005%), and are lethal after single ingestion of bait and are effective also against strains of rodents that have become resistant against first generation anticoagulants; thus the second generation anticoagulants are sometimes referred to as “superwarfarins”. Sometimes, anticoagulant rodenticides are potentiated by an antibiotic, most commonly by sulfaquinoxaline. The aim of this association (e.g. warfarin 0.05%+sulfaquinoxaline 0.02%, or difenacoum 0.005%+sulfaquinoxaline 0.02% etc.) is that the antibiotic/bacteriostatic agent suppresses intestinal/gut symbiotic microflora that represents a source of vitamin K. Thus the symbiotic bacteria are killed or their metabolism is impaired and the production of vitamin K by them is diminuted, an effect which logically contributes to the action of anticoagulants. Antibiotic agents other than sulfaquinoxaline may be used, for example co-trimoxazole, tetracycline, neomycin or metronidazole. A further synergism used in rodenticidal baits is that of an association of an anticoagulant with a compound with vitamin D-activity, i.e. cholecalciferol or ergocalciferol (see below). A typical formula used is, e.g., warfarin 0.025-0.05%+cholecalciferol 0.01%. In some countries there are even fixed three-component rodenticides, i.e. anticoagulant+antibiotic+vitamin D, e.g. difenacoum 0.005%+sulfaquinoxaline 0.02%+cholecalciferol 0.01%. Associations of a second-generation anticoagulant with an antibiotic and/or vitamin D are considered to be effective even against the most resistant strains of rodents, though some second generation anticoagulants (namely brodifacoum and difethialone), in bait concentrations of 0.0025-0.005% are so toxic that no known resistant strain of rodents exists and even rodents resistant against any other derivatives are reliably exterminated by application of these most toxic anticoagulants.
Vitamin K1 has been suggested and successfully used as an antidote for pets or humans, which/who were either accidentally or intentionally (poison assaults on pets, suicidal attempts) exposed to anticoagulant poisons. In addition, since some of these poisons act by inhibiting liver functions and in progressed stages of poisoning, several blood-clotting factors as well as the whole volume of circulating blood lacks, a blood transfusion (optionally with the clotting factors present) can save a person's life who inadvertently takes them, which is an advantage over some older poisons.
Metal phosphides have been used as a means of killing rodents and are considered single-dose fast acting rodenticides (death occurs commonly within 1-3 days after single bait ingestion). A bait consisting of food and a phosphide (usually zinc phosphide) is left where the rodents can eat it. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas. This method of vermin control has possible use in places where rodents are resistant to some of the anticoagulants, particularly for control of house and field mice; zinc phosphide baits are also cheaper than most second-generation anticoagulants, so that sometimes, in cases of large infestation by rodents, their population is initially reduced by copious amounts of zinc phosphide bait applied, and the rest of the population that survived the initial fast-acting poison is then eradicated by prolonged feeding on anticoagulant bait. Inversely, the individual rodents that survived anticoagulant bait poisoning (rest population) can be eradicated by pre-baiting them with nontoxic bait for a week or two (this is important to overcome bait shyness, and to get rodents used to feeding in specific areas by offering specific food, especially when eradicating rats) and subsequently applying poisoned bait of the same sort as used for pre-baiting until all consumption of the bait ceases (usually within 2-4 days). These methods of alternating rodenticides with different modes of action provides a factual or an almost 100% eradication of the rodent population in the area if the acceptance/palatability of bait is good (i.e., rodents readily feed on it).
Phosphides are rather fast acting rat poisons, resulting in that the rats are dying usually in open areas instead of the affected buildings. Typical examples are aluminum phosphide (fumigant only), calcium phosphide (fumigant only), magnesium phosphide (fumigant only) and zinc phosphide (in baits). Zinc phosphide is typically added to rodent baits in amounts of around 0.75-2%. The baits have a strong, pungent garlic-like odor characteristic for phosphine liberated by hydrolysis. The odor attracts (or, at least, does not repulse) rodents, but has a repulsive effect on other mammals; birds, however (notably wild turkeys), are not sensitive to the smell and feed on the bait thus becoming collateral damage.
Hypercalcemia. Calciferols (vitamins D), cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are used as rodenticides, which are toxic to rodents for the same reason that they are beneficial to mammals: they are affecting calcium and phosphate homeostasis in the body. Vitamins D are essential in minute quantities (few IUs per kilogram body weight daily, which is only a fraction of a milligram), and like most fat soluble vitamins they are toxic in larger doses as they readily result in the so-called hypervitaminosis, which is, simply said, poisoning by the vitamin. If the poisoning is severe enough (that is, if the dose of the toxicant is high enough), it eventually leads to death. In rodents consuming the rodenticidal bait it causes hypercalcemia by raising the calcium level, mainly by increasing calcium absorption from food, mobilising bone-matrix-fixed calcium into ionised form (mainly monohydrogencarbonate calcium cation, partially bound to plasma proteins, [CaHCO3]+), which circulates dissolved in the blood plasma, and after ingestion of a lethal dose the free calcium levels are raised sufficiently so that blood vessels, kidneys, the stomach wall and lungs are mineralised/calcificated (formation of calcificates, crystals of calcium salts/complexes in the tissues thus damaging them), leading further to heart problems (myocard is sensitive to variations of free calcium levels that are affecting both myocardial contractibility and excitation propagation between atrias and ventriculas) and bleeding (due to capillary damage) and possibly kidney failure. It is considered to be single-dose, or cumulative (depending on concentration used; the common 0.075% bait concentration is lethal to most rodents after a single intake of larger portions of the bait), sub-chronic (death occurring usually within days to one week after ingestion of the bait). Applied concentrations are 0.075% cholecalciferol and 0.1% ergocalciferol when used alone. There is an important feature of calciferols toxicology which is that they are synergistic with anticoagulant toxicants. This means that mixtures of anticoagulants and calciferols in the same bait are more toxic than the sum of toxicities of the anticoagulant and the calciferol in the bait so that a massive hypercalcemic effect can be achieved by substantially lower calciferol content in the bait and vice-versa. More pronounced anticoagulant/hemorrhagic effects are observed if calciferol is present. This synergism is mostly used in baits low in calciferol because effective concentrations of calciferols are more expensive than effective concentrations of most anticoagulants. The historically very first application of a calciferol in rodenticidal bait was, in fact, the Sorex product Sorexa® D (with a different formula than today's Sorexa® D) back in the early 1970's, containing warfarin 0.025%+ergocalciferol 0.1%. Today, Sorexa® CD contains a 0.0025% difenacoum+0.075% cholecalciferol combination. Numerous other brand products containing either calciferols 0.075-0.1% (e.g. Quintox®, containing 0.075% cholecalciferol) alone, or a combination of calciferol 0.01-0.075% with an anticoagulant are marketed.
g) Miticides, Moluscicides and Nematicides
Miticides are pesticides that kill mites. Antibiotic miticides, carbamate miticides, formamidine miticides, mite growth regulators, organochlorine, permethrin and organophosphate miticides all belong to this category. Molluscicides are pesticides used to control mollusks, such as moths, slugs and snails. These substances include metaldehyde, methiocarb and aluminium sulfate. A nematicide is a type of chemical pesticide used to kill parasitic nematodes (a phylum of worm). A nematicide is obtained from a neem tree's seed cake; which is the residue of neem seeds after oil extraction. The neem tree is known by several names in the world but was first cultivated in India since ancient times.
h) Antimicrobials
In the following examples, antimicrobials suitable for agrochemical compositions according to the present invention are given. Bactericidal disinfectants mostly used are those applying

    
    
        active chlorine (i.e., hypochlorites, chloramines, dichloroisocyanurate and trichloroisocyanurate, wet chlorine, chlorine dioxide, etc.),
        active oxygen (peroxides such as peracetic acid, potassium persulfate, sodium perborate, sodium percarbonate and urea perhydrate),

        heavy metals and their salts such as colloidal silver, silver nitrate, mercury chloride, phenylmercury salts, copper sulfate, copper oxide-chloride etc. Heavy metals and their salts are the most toxic and environmentally hazardous bactericides and, therefore, their use is strongly suppressed or forbidden; further, also
        properly concentrated strong acids (phosphoric, nitric, sulfuric, amidosulfuric, toluenesulfonic acids) and
        alcalis (sodium, potassium, calcium hydroxides) between pH<1 or >13, particularly below elevated temperatures (above 60° C.) kill bacteria.
    
    


As antiseptics (i.e., germicide agents that can be used on human or animal body, skin, mucoses, wounds and the like), few of the above mentioned disinfectants can be used under proper conditions (mainly concentration, pH, temperature and toxicity toward man/animal). Among them, important are

    
    
        Some properly diluted chlorine preparations (e.g. Daquin's solution, 0.5% sodium or potassium hypochlorite solution, pH-adjusted to pH 7-8, or 0.5-1% solution of sodium benzenesulfochloramide (chloramine B)), some
        iodine preparations such as iodopovidone in various galenics (ointments, solutions, wound plasters), in the past also Lugol's solution,
        peroxides as urea perhydrate solutions and pH-buffered 0.1-0.25% peracetic acid solutions,
        alcohols with or without antiseptic additives, used mainly for skin antisepsis,
        weak organic acids such as sorbic acid, benzoic acid, lactic acid and salicylic acid
        some phenolic compounds such as hexachlorophene, triclosan and Dibromol, and
        cation-active compounds such as 0.05-0.5% benzalkonium, 0.5-4% chlorhexidine, 0.1-2% octenidine solutions.
    
    


Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics only slow down their growth or reproduction. Penicillin is a bactericide, as are cephalosporins. Aminoglycosidic antibiotics can act in both a bactericidic manner (by disrupting cell wall precursor leading to lysis) or bacteriostatic manner (by connecting to 30 s ribosomal subunit and reducing translation fidelity leading to inaccurate protein synthesis). Other bactericidal antibiotics according to the present invention include the fluoroquinolones, nitrofurans, vancomycin, monobactams, co-trimoxazole, and metronidazole Preferred actives are those with systemic or partially systemic mode of action such as for example azoxystrobin.

The alkyl or alkenyl oligoglycosides representing also preferred emulsifiers may be derived from aldoses or ketoses containing 5 or 6 carbon atoms, preferably glucose. Accordingly, the preferred alkyl and/or alkenyl oligoglycosides are alkyl or alkenyl oligoglucosides. These materials are also known generically as “alkyl polyglycosides” (APG). The alk(en)yl oligoglycosides according to the invention correspond to formula (IV):

R4O[G]p  (IV)

wherein R4 is an alkyl or alkenyl radical having from 6 to 22 carbon atoms, G is a sugar unit having 5 or 6 carbon atoms and p is a number from 1 to 10. The index p in general formula (II) indicates the degree of oligomerisation (DP degree), i.e. the distribution of mono- and oligoglycosides, and is a number of 1 to 10. Whereas p in a given compound must always be an integer and, above all, may assume a value of 1 to 6, the value p for a certain alkyl oligoglycoside is an analytically determined calculated quantity which is mostly a broken number. Alk(en)yl oligoglycosides having an average degree of oligomerisation p of 1.1 to 3.0 are preferably used. Alk(en)yl oligoglycosides having a degree of oligomerisation below 1.7 and, more particularly, between 1.2 and 1.4 are preferred from the applicational point of view.

The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C8/18 alkyl or acyl group, contain at least one free amino group and at least one —COOH— or —SO3H— group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group.

INDUSTRIAL APPLICATION
Another embodiment of the present invention is related to the use of glycerol(ether)phosphates, in particular its ammonium salts, as adjuvants for biocides. Finally, glycerol(ether)phosphate represent effective sequestrants for alkaline earth metal ions, specifically for calcium and magnesium ions, in biocide compositions, in particular in glyphosate compositions comprising hard water cations.
EXAMPLES
Example 1
Manufacturing of Glycerolphosphate
250 g (2.72 moles) of glycerol and 2.2 g of hypophosphorous acid were introduced into a stirred reactor and heated to 60° C. 852 g of polyphosphoric acid 84% (5.0 moles) were added gradually keeping the temperature below 90° C. After the addition the reaction was kept one hour at 90° C. and then heated to 110° C. The reaction mixture was stirred under these conditions for two hours and neutralized by adding aqueous ammonia.
Examples 2, Comparative Examples C1 to C4
Biological Field Trials
Aqueous mixtures of ammonium salts of glycerol mono/di/triphosphates obtained according to Example 1 were combined with glyphosate isopropylamine salt and tested in the field to control Bristly Foxtail (Setaria verticillata) and White Clover (Trifolium repens). The glyphosate was applied to the subject weeds at a rate of 360 g ae/ha and the glycerol phosphate mixture at 80 g/ha in 160 liters 500 ppm (Ca2+, Mg2+) water per hectare. For comparison, the glycerol phosphate was substituted by tallowamine+20EO (TAM-20), adding optionally ammonium sulphate in an amount of 0.85 to 0.425 g/ha. The spray volume has been 160 l/ha. The treatment was conducted over a period of 28 days (4 replications). Assessments took place at 7, 14 and 28 days after treatment. The results are summarized in the following Table 1. The numbers in the table represent % control of the specified weeds. 0% represents a healthy weed population with no apparent damage, 100% represents no living tissue evident for the specified weed population. The rating is given for each 10×0.5 m2 plot containing 10 to 30 specimens. Four different plots (randomly placed throughout the location) have been averaged together to give the rating in the table.
