Table 20 nitre benzene bacterium amine and active component B and the composite control citrus anthracnose test of pesticide effectiveness thereof
As can be seen from Table 20, nitre benzene bacterium amine and active component B composite after effectively can prevent and treat citrus anthracnose, through applicant test find nitre benzene bacterium amine and active component B composite after also effectively can prevent and treat citrus scab, 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.
After draw through tests different local throughout the country, nitre benzene bacterium amine and pyraclostrobin, oxime kresoxim-methyl, kresoxim-methyl, Enestroburin, azoles bacterium ester, the composite rear preventive effect to Common Diseases such as the downy mildew in various crop, scab, epidemic disease, rust, powdery mildew, spot defoliation, rice blast, banded sclerotial blight, leaf mold, shot hole, peronospora tabacina, anthracnose, brown spot, ring spot, fusarium wilt, root rot, leaf spot, leaf blights of ZEN 90160 are all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
