As can be seen from Table 20, after azoles mepanipyrim and active component B are composite, can effectively prevent and treat citrus anthracnose, test and find that azoles mepanipyrim and active component B also can effectively prevent and treat citrus scab after composite through applicant, control efficiency is all higher than 96%, 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, azoles mepanipyrim and pyraclostrobin, oxime bacterium ester, ZJ0712, fluoxastrobin or ZEN 90160 composite rear to the preventive effect of the Common Diseases such as the downy mildew in various crop, scab, epidemic disease, rust, powdery mildew, spot defoliation, rice blast, banded sclerotial blight, false smut, bakanae disease, damping off, leaf mold, shot hole, peronospora tabacina, anthracnose, brown spot, ring spot, fusarium wilt, root rot, leaf spot or leaf blight all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
