Initial stage dispenser 3 days after dispenser, investigates disease indexes and calculates preventive effect for 10 days, 20 days.Test result is as follows：
18 fluorine ether bacterium amide of table and active constituent B and its compounding prevention downy mildew of garpe test of pesticide effectiveness
As can be seen from Table 18, downy mildew of garpe can be effectively prevented after fluorine ether bacterium amide and active constituent B compoundings, through Shen
It asks someone effectively prevent uncinula necator, white rot, white powder after experiment finds fluorine ether bacterium amide and active constituent B compoundings
Disease, anthrachose of grape and anthracnose, control effect are above 97%, are better than the preventive effect of single dose, and preventive effect phase is long.In experiment medication model
It encloses and interior has no adverse effects to target crop.
The experiment by different places throughout the country obtains afterwards, fluorine ether bacterium amide with after active constituent B compounding to a variety of
It is downy mildew, gray mold, epidemic disease, shot hole, smut, leaf spot, scab, stem wilt, spot defoliation on crop, black
The preventive effect of the Common Diseases such as acne disease, anthracnose, banded sclerotial blight, powdery mildew, rust or white rot 97% or more, is better than single dose
Preventive effect, synergistic effect are apparent.
