experiment example 1

[0034] Experimental example 1 The present invention prevents and treats bakanae disease, damping-off disease and single-dose formula comparative test report.

[0035] The present invention prevents and cures bakanae disease and blight through multiple tests, and compares tests with commonly used medicaments in production, and the control effects are higher and more stable. In order to verify the effect of the comparative test with a single agent, this test was carried out, and the test results as follows:

Abstract

The invention relates to an agricultural chemical for controlling bakanae disease and drooping disease of rice, which belongs to agricultural chemicals and comprises the following materials with the weight percentages: 3-8% of metalaxyl, 15-25% of Prochloraz, and remaining carriers. The invention has the advantage that the invention provides a principle of integrated control technique according to the problems of control measurements existing in current production on the basis of firstly ensuring the regularity of bakanae disease and drooping disease outbreaks in the conditions of heat preservation and dry cultivation, i.e. once application by sterilizing and soaking seeds can control two diseases of bakanae disease and drooping disease; after being soaked, liquid medicine can be applied into seedbeds without environmental pollution.

Description

technical field [0001] The invention belongs to a kind of pesticide. Background technique [0002] Rice bakanae disease can occur at the seedling stage and the adult plant stage, and when it occurs seriously at the seedling stage, the seedlings will be destroyed and cannot be transplanted. When it happens to Honda, it will directly affect the output and cause economic losses. It is economical and effective to prevent and control the disease by soaking seeds with medicaments, but long-term use of a single medicament will easily lead to drug resistance of the bacteria, and the control effect is poor. [0003] Rice blight is the most important disease at the seedling stage, which is common and serious. Every year in Northeast, Inner Mongolia, Northwest, North China and other places, it occurs to varying degrees. When it occurs lightly, it forms spots, which affects the quality of rice seedling transplanting. When serious, the seedlings will die in pieces, which will affect t...
