Chemical property

Industrial products are yellow to light brown transparent liquid, with a foul smell. B.p.154 C /1.33Pa, relative density 1.23 (20 C), refractive index n22D1.61. Soluble in methanol, ether, chloroform, acetone, benzene, xylene and other organic solvents, insoluble in water. The half-life at 1.135h was 25 (pH=7) and 49h (pH=9). Acidic conditions are relatively stable, and hydrolysis or transesterification reactions are easy to occur in alkaline conditions, especially at higher temperatures.

Purpose

Broad-spectrum organophosphorus fungicide has the function of internal absorption and protection and treatment. It is mainly used to control rice blast, and has good control effect on rice leaf blast, ear neck blast and seedling blast. For example, spraying water with 40% EC 7.5-10.5mL/100m2 before disease, 11.3-15mL/100m2 10-14 days after relapse, the same dosage of EC and seed treatment can prevent and cure seedling blast. In addition, it can also be used to control wheat scab, rice granular sclerotinia, rice sheath blight, corn leaf spot, flax leaf spot, rice leafhopper, rice borer and so on. This agent has obvious effect before the invasion of pathogenic bacteria.

It is an organophosphorus fungicide, mainly used to control rice blast. It can also control rice flax leaf spot, rice granular sclerotinia, sheath blight and so on. It also can control rice planthopper and leafhopper. Mice were given oral LD50 for 214mg/kg.
