Patent ID: 8298559

Claim:
A mammalian safe, low-toxicity pesticide for delivering a physical mode of action kill comprising: (a) a mammalian safe, low-toxicity active ingredient comprising a polysaccharide selected from the group consisting of xanthan gum, alginate gum, alginic acid, propylene glycol alginate, starches, dextrins, corn starches comprising 100% amylopectin, corn starches comprising a mixture of amylopectin and amylose, glycogen, agar, pectin, carrageenan, other natural gums and combinations thereof, said active ingredient being present in a concentration of from about 0.10 wt. % to about 1.0 wt. % based on the total weight of said pesticide; (b) about 20 wt. % to about 40 wt. % of a mammalian safe, low-toxicity surfactant selected from the group consisting of salts of fatty acids, alkyl sulphates, alkyl ether sulphonates, alkyl aryl sulphonates and combinations thereof; (c) about 10 wt. % to about 25 wt. % of a mammalian safe, low-toxicity co-solvent selected from the group consisting of glycols, esters of straight-chain alcohols, esters of branched-chain alcohols, hydrocarbons, ethers, phenols, glycols, lactones, nitrated hydrocarbons, dibasic esters, ethyl acetate, butyl acetate, ethyl-3-ethoxy-propionate, propylene glycol propanediol, propylene glycol butyl ether acetate, dipropylene glycol methyl ether acetate, tetrahydrofurfuryl alcohol and combinations thereof; (d) about 40 wt. % to about 65 wt. % of a diluent comprising water; and (e) about 0.5 wt. % to about 2.0 wt. % of a mammalian safe, low-toxicity pest targeting ingredient selected from the group consisting of ionic salts, non-ionic salts, esters, amino acids, peptides, proteins and combinations thereof, said pest targeting ingredient being able to increase the effectiveness of said active ingredient; (f) optionally about 0 wt. % to about 0.08 wt. % of a mammalian safe, low toxicity coloring agent; and (g) optionally about 0.01 wt. % to about 1.0 wt. % of a mammalian safe, low-toxicity buffering agent selected from the group consisting of potassium hydroxide, ammonium bicarbonate, ammonium phosphate dibasic, diammonium phosphate and combinations thereof; wherein said polysaccharide is in the form of a micelle in a colloid suspension and is present in an amount sufficient to cause a physical mode of action kill in insects, wherein said wt. % is based on the total weight of said pesticide; with the proviso that no other pesticidally active ingredient is present in the pesticide.
