Claims
- 1. 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.
- 2. A composition according to claim 1, in which the ratio is within the range from 10:1 to 20:1.
- 3. A composition according to claim 1, comprising an inert carrier and a content of active arthropodicide within the range from about 0.1 to about 95%.
- 4. A composition according to claim 3, in the form of a solution of active anthropodicides in a solvent therefor as the inert carrier.
- 5. A composition according to claim 4, in the form of an aqueous emulsion of the solution of the active arthropodicides in a solvent and comprising a wetting agent or dispersing agent.
- 6. A composition according to claim 4, in which the carrier is a solid and the composition is in particulate form.
- 7. A process for control of arthropods, which comprises applying to the arthropod a toxic amount of a composition according to claim 1.
