History Insecticide developed by Takeda Chemical Industries, Ltd. (now Sumitomo Chemical Takeda Agro Company Ltd) and first marketed in 1983. Manufacturers Sumitomo Chemical Takeda

Biochemistry Analogue or propesticide of the natural toxin nereistoxin. Acts as a synaptic blocking agent for the insect central nervous system. Inhibits the action of synaptic transmitter (acetylcholine) by occupying the post-synaptic membrane where the acetylcholine receptor exists. Mode of action Insecticide with contact and stomach action. Uses Control of major agricultural insect pests, particularly Coleoptera and Lepidoptera. In particular, control of Colorado beetles in potatoes and aubergines; tea leaf rollers and yellow tea thrips in tea; rice stem borers, rice leaf rollers, rice leaf miners and rice leaf beetles in rice; Oriental corn borers and Tanymecus spp. in maize; Tanymecus spp., root weevils, and tortoise beetles in beet; grape berry moths on vines; leaf beetles in cereals; boll weevils in cotton; codling moths, blister moths, and leaf miners in apples; small cabbage-white butterfly larvae, diamond-back moths, and blossom rape beetles on brassicas and oilseed rape; etc. Typical application rate is in the range 0.25-1.5 kg/ha. Phytotoxicity May be phytotoxic to certain varieties of apple, peach and citrus. Formulation types DP; GR; WP. Compatibility Not compatible with alkaline materials.
