As can be seen from Table 16, after fluorine mepanipyrim and active component B are composite, can effectively prevent and treat rice blast, through applicant test find fluorine mepanipyrim and active component B also can preventing and controlling green smut of rice after composite, rice sheath blight disease, Rice Leaf rot and bakanae disease of rice, control efficiency is all higher than 95%, be better than the preventive effect of single dose, and the preventive effect phase is long.In test scope of medication, target crop is had no adverse effects.
Application Example ten fluorine mepanipyrims and active component B and the composite downy mildew of garpe test of pesticide effectiveness of preventing and treating thereof
This test arrangement is at Xian District, Shanxi Province suburban area, and investigation downy mildew of garpe disease index before medicine, in the dispenser of disease initial stage of origination, investigates disease indexes and calculate preventive effect for after dispenser 3 days, 10 days, 30 days.Result of the test is as follows:
Table 17 fluorine mepanipyrim and active component B and the composite downy mildew of garpe test of pesticide effectiveness of preventing and treating thereof
As can be seen from Table 17, after fluorine mepanipyrim and active component B are composite, can effectively prevent and treat downy mildew of garpe, test and find that fluorine mepanipyrim and active component B also can effectively prevent and treat grape powdery mildew, anthrachose of grape, zonate spot, leaf spot, brown spot and gray mold after composite through applicant, control efficiency is all higher than 97%, be better than the preventive effect of single dose, and the preventive effect phase is long.In test scope of medication, target crop is had no adverse effects.
After draw through different local throughout the country tests, fluorine mepanipyrim and Prochloraz or its salt, Fenamidone, carbendazim or thiophanate-methyl are composite rear to the leaf blight in various crop, anthracnose, brown spot, downy mildew, powdery mildew, gray mold, head blight, fusarium wilt, anthrachose of grape, false smut, rice blast, epidemic disease, black spot, seedling laying disease, leaf spot, scab, ring spot, spot defoliation, banded sclerotial blight, stalk break, leaf mold, penicilliosis, smut, the preventive effect of the Common Diseases such as rot or zonate spot is all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
