Title: Use of n-arylhydrazine derivatives for combating non-crop pests

Description:
The present invention relates to the use of hydrazine derivatives of formula I:  
                 
 
 wherein 
      W is chlorine or trifluoromethyl;     X and Y are each independently chlorine or bromine;     R 1  is C 1 -C 6 -alkyl, C 3 -C 6 -alkenyl, C 3 -C 6 -alkynyl, or 
        C 3 -C 6 -cycloalkyl which may be substituted with 1 to 3 halogen atoms, or C 2 -C 4 -alkyl which is substituted by C 1 -C 4 -alkoxy;    
        R 2  and R 3  are C 1 -C 6 -alkyl or may be taken together to form C 3 -C 6 -cycloalkyl which may be unsubstituted or substituted by 1 to 3 halogen atoms;     R 4  is hydrogen or C 1 -C 6 -alkyl, 
 
 or the enantiomers or salts thereof, 
 
 for combating non-crop pests. 
   

      The invention also relates to a method for controlling non-crop pests comprising contacting the pests or their food supply, habitat, breeding grounds or their locus with a pesticidally effective amount of a compound of formula I.  
      The invention also relates to compositions containing compounds of formula I for in pesticidally effective amounts for controlling non-crop pests.  
      The invention further relates to the use of compounds of formula I for the protection of non-living organic materials against non-crop pests.  
      Typical problems arising with the use of presently available non-crop pest control agents such as pyrethroids are e.g. resistance of pests or unfavorable environmental or toxicological properties. Another problem encountered concerns the need to have available non-crop pest control agents which are effective against a broad spectrum of non-crop pests. Accordingly, there is a need to provide new and improved non-crop pest control agents that overcome these problems.

      The hydrazine derivatives of formula I which can be used according to the invention are known from and can be prepared according to preparation methods described or referenced in EP-A 604 798. This document relates to plant protection in the agricultural field and discloses the insecticidal and acaricidal activity of compounds of formula I and other compounds against crop pests of the Coleoptera, Lepidoptera and Acarina orders.  
      In J. A Furch et al., “Amidrazones: A New Class of Coleopteran Insecticides”, ACS Symposium Series 686, Am. Chem. Soc., 1998, Chapter 18, p. 178 ff, the use of certain amidrazones against southern corn rootworm is exemplified, some of which amidrazones are compounds of formula I. It is taught that these compounds target specifically certain coleopteran insects while being little toxic or non-toxic to Lepidoptera and other insects as well as to Acarina.  
      In D. G. Kuhn et al., “Cycloalkyl-substituted Amidrazones: A Novel Class of Insect Control Agents”, ACS Symposium Series 686, Am. Chem. Soc., 1998, Chapter 19, p. 185 ff, it is taught that certain amidrazones, some of which amidrazones are compounds of formula I wherein R 2  and R 3  together form a cyclopropyl ring, are active against certain Coleopteran and Lepidoptera species. Biological tests show that the compounds are quite selective, only some exhibiting good activity against both Coleoptera or Lepidoptera.  
      Activity of a compound against pests for plant protection in the agricultural field, that is, against crop pests, does not generally suggest activity of that compound against non-crop pests. Crop pest control always is a part of plant protection. Non-crop pest control, on the contrary, e.g. relates to protection of non-living organic materials, or hygiene and disease prevention (public health).  
      The differences in requirements for crop/non-crop pest control generally and mainly—beside a possible difference in biochemical targets—emerge from the differences in the food and/or habitat of the pests.  
      Crop pests like that of the order Homoptera feed on the green parts of the plant by piercing them and sucking the plant liquids. Other crop pests of the Lepidoptera and Coleoptera order feed on the green parts of plants by biting off parts. On the contrary, non-crop pests do not live on plants and do not or only in rare occasions feed on the green parts of the plant. Non-crop pests e.g. feed on non-living organic materials such as the homes, clothing and the food etc of human beings and animals but also on electric wires etc thereby introducing pathogenic germs into the human being&#39;s environment and destroying their homes and food. An example is the termite (order Isoptera) that primarily feeds on cellulose which is the major component of wood and paper products. Another example is the mosquito (order Diptera) whose larvae feed on microorganisms and organic matter in the water and whose adults feed on blood.  
      The properties of pesticides need to be adapted to their specific use. Systemic pesticides for example that by virtue of their water-solubility are introduced into the plant parts are suitable for controlling piercing-sucking or biting (i.e. crop) pests. However, they cannot generally be expected to show equal activity against non-crop pests who do not feed on the green plant parts but are controlled by mostly water-insoluble pesticides in baiting systems or by direct treatment. In many cases crop pest control pesticides are not suitable for non-crop pest controlling and vice versa. The market insecticides pirimicarb, acephate, pyrimidiven, and pyridaben are examples. They are active against crop insects but show low activity against non-crop pests.  
      Summing up, prior art teaches the artisan that amidrazones of formula I and of similar structure exhibit selective activity against certain crop pests of the orders Coleoptera or Lepidoptera and that small changes of the structure have a tremendous effect on selectivity.  
      Suprisingly, it has now been found that a certain group of amidrazones, namely the compounds of formula I, exhibit broad spectrum activity against non-crop pests.

      J ULV Solutions (UL)  
      10 parts by weight of a compound according to the invention are dissolved in an organic solvent, for example xylene. This gives a product to be applied undiluted.  
      The active ingredients can be used as such, in the form of their formulations or the use forms prepared therefrom, eg. in the form of directly sprayable solutions, powders, gels, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, microcapsules (CS), pellets or tablets, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; it is intended to ensure in each case the finest possible distribution of the active ingredients according to the invention.  
      Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.  
      The active ingredient concentrations in the ready-to-use products can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1%.  
      The active ingredients may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active ingredient, or even to apply the active ingredient without additives.  
      Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate just immediately prior to use. These agents usually are admixed with the agents according to the invention in a weight ratio of 1:10 to 10:1.  
      The compounds of formula I are effective through both direct and indirect contact and ingestion, and also through trophallaxis and transfer.  
      Preferred application methods are into water bodies, via soil, cracks and crevices, pastures, manure piles, sewers, into water, on floor, wall, or by perimeter spray application and bait.  
      According to a preferred embodiment of the invention, the compounds of formula I are employed via soil application. Soil application is especially favorable for use against ants, termites, wasps, crickets, or cockroaches.  
      According to another preferred embodiment of the invention, for use against non crop pests such as ants, termites, wasps, flies, mosquitoes, crickets, locusts, cockroaches, and firebrats the compounds of formula I are prepared into a bait preparation.  
      The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). Solid baits can be formed into various shapes and forms suitable to the respective application e.g. granules, blocks, sticks, disks. Liquid baits can be filled into various devices to ensure proper application, e.g. open containers, spray devices, droplet sources, or evaporation sources. Gels can be based on aqueous or oily matrices and can be formulated to particular necessities in terms of stickiness, moisture retention or aging characteristics.  
      The bait employed in the composition is a product which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitoes, crickets etc. or cockroaches to eat it. This attractant may be chosen from feeding stimulants or para and/or sex pheromones. Suitable feeding stimulants are chosen, for example, from animal and/or plant proteins (meat-, fish- or blood meal, insect parts, crickets powder, egg yolk), from fats and oils of animal and/or plant origin, or mono-, oligo- or polyorganosaccharides, especially from sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molasses or honey, or from salts such as ammonium sulfate, ammonium carbonate or ammonium acetate. Fresh or decaying parts of fruits, crops, plants, animals, insects or specific parts thereof can also serve as a feeding stimulant. Pheromones are known to be more insect specific. Specific pheromones are described in the literature and are known to those skilled in the art.  
      Formulations of compounds of formula I as aerosols (e.g in spray cans), oil sprays or pump sprays are highly suitable for the non-professional user for controlling pests such as flies, fleas, ticks, mosquitoes, locusts or cockroaches. Aerosol recipes are preferably composed of the active compound, solvents such as lower alcohols (e.g. methanol, ethanol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffin hydrocarbons (e.g. kerosenes) having boiling ranges of approximately 50 to 250° C., dimethylformamide, N-methylpyrrolidone, dimethyl sulphoxide, aromatic hydrocarbons such as toluene, xylene, water, furthermore auxiliaries such as emulsifiers such as sorbitol monooleate, oleyl ethoxylate having 3-7 mol of ethylene oxide, fatty alcohol ethoxylate, perfume oils such as ethereal oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds, if appropriate stabilizers such as sodium benzoate, amphoteric surfactants, lower epoxides, triethyl orthoformate and, if required, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide, or mixtures of these gases.  
      The oil spray formulations differ from the aerosol recipes in that no propellants are used.  
      The compounds of formula I and its respective compositions can also be used in mosquito coils and fumigating coils, smoke cartridges, vaporizer plates, long-term vaporizers, or other heat-independent vaporizer systems.  
      Methods to control infectious diseases transmitted by insects (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) with compounds of formula I and its respective compositions also comprise treating surfaces of huts and houses, air spraying and impregnation of curtains, tents, clothing items, bed nets, tsetse-fly trap or the like. Insecticidal compositions for application to fibers, fabric, knitgoods, nonwovens, netting material or foils and tarpaulins preferably comprise a mixture including the insecticide, optionally a repellent and at least one binder.  
      The impregnation of curtains and bed nets is mostly done by dipping the textile material into emulsions or dispersions of the insecticide or spraying them onto the nets.

Each vial was rolled uncapped for ca. 10 minutes to allow the a.i. to completely coat the vial and to allow for full drying of the acetone. Insects or ticks were placed into each vial. The vials were kept at 22° C. and were observed for treatment effects at various time intervals. Results are presented in Table I.  
      2. Activity Against Argentine Ant, Acrobat Ant, Carpenter Ant, Fire Ant, and Eastern Subterranean Termite Via Soil Contact  
      For ants, tests were conducted in Petri dishes. A thin layer of 1% agar in water was dispensed into the dishes and Florida sandy soil was spread over the agar (5 g for the small dishes and 11 g for the larger dishes). The active ingredient was dissolved in acetone and dispensed over the sand. Dishes were vented to evaporate the acetone, infested with ants, and covered. A 20% honey water solution was placed in each dish. The dishes were maintained at 22° C. and observed for mortality at various time intervals.  
      For termites, a thin layer of 1% agar was dispensed into Petri dishes. A thin layer of pre-treated soil was spread over the agar. For soil treatment, the active ingredient was diluted in acetone on a weight-to-weight basis and incorporated into 100 g of soil. The soil was placed in a jar and vented for 48 hours. The moisture level of the soil was brought to field capacity by adding 7 ml of water. Termite workers were introduced into each dish. A small piece of filter paper was placed into each dish after 1 day as a food source, and additional water was added as needed to maintain soil moisture. Test dishes were held at a dark incubator at 25° C. and appr. 80% relative humidity. Termites were observed daily for mortality (dead or unable to stand upright and showing only weak movement). Results are shown in Table I.  
      3. Activity Against Argentine Ant, Acrobat Ant, Carpenter Ant, Fire Ant, House Fly, Eastern Subterranean Termite, Formosan Subterranean Termite, and German Cockroach Via Bait  
      For Argentine ant, acrobat ant, and carpenter ant, tests were conducted in Petri dishes. Ants were given a water source, and then were starved of a food source for 24 hours. Baits were prepared with either 20% honey/water solutions or ground cat chow. Active ingredient in acetone was added to the bait. 0.2 ml of treated honey water solution or 150 mg of treated cat chow, placed in a cap, was added to each dish. The dishes were covered and maintained at a temperature of 22° C. The ants were observed for mortality daily. Results are shown in Table I.  
      For the fire ants, corn grit was used as a bait matrix. Corn grit bait was prepared using a mixture of defatted corn grit (80%), soybean oil (19.9%), acetone, and the active ingredient (0.1%). Petri dishes were supplied with a water source. Fire ant adults were placed into each dish. The next day, 250 mg of bait in bait containers was placed into the dishes. The ants were observed for mortality daily. Results are shown in Table I.  
      For house flies. Bait tests were conducted with adults aged 2-5 days post-emergence. Active ingredient in acetone was applied to a bait matrix consisting of a 1:1 mixture of powdered milk and sugar which was then allowed to dry. Assays were conducted in jars with 250 mg of bait in a pan placed in the bottom of each jar. House flies were placed into the bait jars which were covered. The test jars were held at 22° C. Test jars were observed at 4 hours after treatment for knockdown (death plus morbidity (unable to stay upright). Results are shown in Table I.  
      For termites, active ingredient in acetone was applied to filter papers. % a.i. were calculated on basis of the weight of the filter paper. Acetone only was applied for untreated controls. Treated papers were vented to evaporate the acetone, moistened with ml water, and placed Petri dishes with sand. Water was added during the test as needed. Bioassays were conducted with one treated filter and ca. 30 termite workers per test dish. Test dishes were maintained at 25° C. and appr. 85% relative humidity and observed daily for mortality (dead or moribund insects) or intoxication. Dead or moribund insects were removed daily. Results are shown in Table I.  
      For cockroaches, plastic roach boxes with ventilated lids were used as test arenas. The top 3-4 cm of the arenas was treated with Vaseline and mineral oil to prevent roaches from escaping. Water was provided as needed. The bait was prepared using ground cat chow, and the active ingredient in acetone was incorporated on a weight- to-weight ratio. The treated chow was allowed to dry. The cockroaches were placed in the boxes and starved for 24 hours prior to bait introduction. 0.03 grams of bait per box were placed in a weigh boat. The boxes were maintained at 22° C. and observed daily for mortality of the cockroaches. Results are shown in Table I.  
      4. Activity Against Yellowfever Mosquito, Southern House Mosquito, and Malaria Mosquito Larvae Via Water Treatment  
      Well plates were used as test arenas. The active ingredient was dissolved in acetone and diluted with water to obtain the concentrations needed. The final solutions containing appr. 1% acetone were placed into each well. Approximately 10 mosquito larvae (4 th -instars) in 1 ml water were added to each well. Larvae were fed one drop of liver powder each day. The dishes were covered and maintained at 22° C. Mortality was recorded daily and dead larvae and live or dead pupae were removed daily. At the end of the test remaining live larvae were recorded and percent mortality was calculated. Results are shown in Table I.  
      Each test was replicated at least 3 times.
