EC FORMULATIONS COMPRISING ORGANOPHOSPHATE INSECTICIDES

摘要

Solvent formulations under EC form comprising (% by weight): - 10-40% of one or more compounds having an insecticidal activity selected from the organophosphate class, comprising the following group (formula (I) ) wherein: L1 is selected between oxygen and sulphur, L2 and L3, equal to or different from each other, are selected from oxygen, sulphur or a NH group, with the proviso that at least one from Li, L2 and L3 is sulphur and at least one from L1, L2 and L3 is oxygen, M is selected from oxygen, sulphur or NH; - 1-20% of an additive (A) methyl or ethyl esters of carboxylic acids having a C10-C20 chain, saturated or unsaturated, or mixtures thereof, the fatty acids deriving from vegetal oils; - 0.5-10% of an additive B) of a cellulose derivative soluble in the organic solvent of EC formulation; - 3-15% of one or more surfactants selected from non ionic and anionic surfactants, or thereof mixtures; the complement to 100% being of one or more organic solvents having the following characteristics: - capable to solubilize the active principle, expressed as % by weight, at room temperature (20-25°C) for at least 5%; preferably 10%, more preferably at least 20%, immiscible with water.
