CAS No.2550-02-9 is a white crystalline powder which is an organophosphorus compound. It is mainly used as an insecticide, herbicide and fungicide.
This CAS No.2550-02-9 is an organophosphorus compound, which is a versatile pesticide used in agriculture and public health. It has wide spectrum and strong killing effect to pests, and it is mainly used to kill lepidoptera, coleoptera, diptera, and homoptera. CAS No.2550-02-9 can be used as a contact and stomach poison, which can not only kill the pests directly, but also inhibit the activity of the pest enzyme and disrupt the normal metabolism. It can also be used to control plant diseases and weeds, and has good preventive effect.
CAS No.2550-02-9 has good stability in aqueous solution, good solubility in organic solvents, low toxicity to humans and mammals, low volatility, no pollution to environment and crops, and no residue. Moreover, it has certain selectivity, so it does not kill beneficial organisms. CAS No.2550-02-9 is widely used in cottons, vegetables, fruits, tobacco, rice, melons and other crops, and can control more than 30 pests.
CAS No.2550-02-9 can be applied by foliar application, seed treatment, soil application, and spraying. However, it should be noted that the recommended dosage should not be exceeded, and the general dosage is 0.5-1.5 kg/ha. It is also possible to mix it with other insecticides, fungicides or herbicides to strengthen its control effect.
