Use | This product has poor anti-acetylcholine enzyme activity in vitro, but has good insecticidal activity against Spodoptera litura, the larvae of acetylcholinesterase due to this product poisoning lead to inhibition. This product shows higher inhibitory activity against insect aliphatic esterase (compared with acetylcholinesterase of nervous system). It has the effect of killing and stomach poison, and has no systemic activity to the root system. It is effective against a variety of pests such as Lepidoptera, Coleoptera, aphids, Diptera and cockroaches, and is also effective against spider mites, root mites, ticks and nematodes. Field experiments showed that the control objects included cotton bollworm, pink bollworm, coastal armyworm, cotton planthopper, tobacco thrips, potato beetle, potato tuber moth, tea moth, tea yellow thrips, alfalfa leaf elephant, tobacco day moth. The dosage was 0.5 ~ 1.5kg (active ingredient)/hm2. On the apple, citrus, pear and other fruit trees have a slight injury, with different varieties. |
production method | 1-(4-chlorophenyl) preparation of 4-hydroxypyrazole 1-(4-chlorophenyl) was prepared by cyclization of 3-chloro-acetone aldehyde hydrazone-p-chlorobenzene in the presence of sodium hydroxide in methanol.-4-hydroxypyrazole. Synthesis of thiophos pyrazole 1-(4-chlorophenyl)-4-hydroxypyrazole in the presence of triethylamine in acetonitrile solution, O-ethyl-S-propylthiophosphoryl chloride, the reaction temperature was 50 ℃, and the reaction time was 3H. |
