Abstract

A water-dispersing tablet of probenazole as plant growth regulator with high activity to rice blast is proportionally prepared from probenazole, disintegrant, adhesive, disperser, wetting agent and filler through mixing, pulverizing, sieving and die pressing.

Description

technical field [0001] The invention belongs to the field of pesticide processing, and relates to a new formulation of allylisothiazole, an agricultural plant growth regulator, and a preparation method thereof. Background technique [0002] Allylisothiazole is a variety developed in Japan in the 1970s and is a disease resistance activator. The agent itself has no bactericidal activity, but it can resist diseases by improving crop immunity. The effect of controlling rice blast lasts for 40 days, and it is currently one of the most productive varieties of fungicides in Japan. It induces the disease resistance of rice by inducing the synthesis of phytoalexin in rice plants, the accumulation of disease process-related proteins, and improving the activity of enzymes related to disease resistance. In recent years, sales have increased rapidly due to the new awareness of anti-disease activators that have revived it. The agent is mainly used to prevent and control rice blast, and...
