Abstract
Synergistic pesticidal mixtures are provided that are effective against arthropods such as insects and mites, comprising an O,O-dialkyl diphosphoryl methyl halo-6-benzoxazolone, such as phosalone, and an O,O-dialkyl-(1,2-dicarbalkoxylalkyl)diphosphate, such as malathion. A process is also provided for control of arthropods, i.e., insects and mites, using a mixture of these two compounds.
Claims7
An arthropodicidal composition having an enhanced effectiveness against phosphate-resistant arthropods comprising O,O-diethyl-dithiophosphorylmethyl-3-chloro-6-benzoxazolone and O,O-dimethyl-S-(1,2-dicarbethoxyethyl), dithiophosphate, the weight ratio of amounts of O,O-diethyl-dithiophosphoryl-methyl-3-chloro-6-benzoxazolone and O,O-dimethyl-S-(1,2-dicarbethoxy ethyl) dithiophosphate being within the range from about 0.225:1 to about 50:1, the amounts of O,O-diethyl-dithiophosphoryl-methyl-3-chloro-6-benzoxazolone and O,O-dimethyl-S-(1,2-dicarbethoxy ethyl) dithiophosphate being selected within the stated range, each to synergize the effectiveness of the other.
