Phenthoate solution is a non inhalant insecticide with the advantages of poisoning, low residue and wide insecticidal spectrum. It can protect rice, cotton, vegetables, oil plants, fruit trees and other crops from Lepidoptera, Cicadellidae, aphids and soft beetles. It can be used to replace methamidophos and other pesticides. It is a pesticide variety encouraged to be developed during the Tenth Five Year Plan period. Due to the long-term development of organophosphorus, it is very difficult to develop new active structures. However, in recent years, it has been found that ternary asymmetric structures and heterocyclic structures have the advantages of no interaction and have market prospects. Phenthoate solution is a toxic insecticide, which has no irritating effect on eyes and skin, and has no carcinogenic, teratogenic and mutagenic effects on animals at the test dose. It is toxic to bees and its toxicity to natural enemies is lower than that of general organophosphorus insecticides. Phenthoate solution has contact killing and stomach toxic effects, and its mechanism is to inhibit acetylcholinesterase. Phenthoate solution is a highly effective, broad-spectrum and low toxic non absorbable organophosphorus insecticide, egg and acaricide. Phenthoate solution is suitable for controlling a variety of pests on rice, cotton, fruit trees, vegetables and other crops.
Control of rice pests: Chilo suppressalis, yellow rice borer, use 100-200 ml of 50% missible oil per acre, spray 60-75 kg of water, or add 20-50 kg of fine soil and mix well. This method can also be used to control rice planthoppers, leafhoppers, and mudworms.
Control of cotton pests: To prevent cotton bollworms, aphids and leafhoppers, use 200 ml of 50% missible oil per mu and add 60-75 kg of water to spray.
Control of vegetable pests: To control aphids, cabbage caterpillars, diamondback moths, Spodoptera litura, leafhoppers, use 120-150 ml of 50% missible oil per acre, and spray 50-60 kg of water.
Control of fruit tree pests: Apple leaf rollers, scale insects, heartworms, aphids, citrus blue scales, brown round scales, black spiny whiteflies are sprayed with 50% missible oil 1000 times.
Citrus thrips and citrus leaf miner are sprayed with 800 times liquid of 50% missible oil. The general dosage of phenthoate solution has little impact on fish and scale, but has a great impact on mullet and trout.
