Table 28 simeconazoles and methoxy acrylic and the composite powdery mildew of cucumber test of pesticide effectiveness of preventing and treating thereof
As can be seen from Table 28, after simeconazoles and methoxy acrylic are composite, can effectively prevent and treat powdery mildew of cucumber, control efficiency is all 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.
By all parts of the country test, draw, simeconazoles and methoxy acrylic are composite rear to the leaf spot in various crop, moire disease, net blotch, glume blight, rust, powdery mildew, scab, spot defoliation, downy mildew, peronospora tabacina, anthracnose, leaf mold, late blight, shot hole, climing rot, epidemic disease, anthrachose of grape, black spot, rice blast, false smut, banded sclerotial blight, damping off, bakanae disease, brown spot, leaf rust, yellow rust, spike rot, ring spot, fusarium wilt, rot, the preventive effect of the Common Diseases such as gray mold is all greater than 95%, be better than single dose preventive effect, synergy is obvious.
