As can be seen from Table 23, Fenarimol and active component B composite after can effectively prevent and treat flowers powdery mildew, 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.
Draw by all parts of the country test, Fenarimol and the composite rear preventive effect to Common Diseases such as the scab in various crop, powdery mildew, spot defoliation, shot hole, false smut, rice blast, banded sclerotial blight, leaf spot, rust, downy mildew, peronospora tabacina, leaf mold, anthracnose, damping off, glume blight, epidemic disease, net blotch, white rots of active component B are all greater than 95%, be better than single dose preventive effect, synergy is obvious.
