This test arrangement, in Weinan City Dali County, Shaanxi Province, is investigated the downy mildew of garpe state of an illness before medicine, in the dispenser for the first time of state of an illness initial stage, once, dispenser is 2 times altogether in dispenser in every 7 days.Within after dispenser 7 days, 14 days, 30 days for the second time, investigate respectively disease index and calculate preventive effect.Experimental result is as follows:
Table 21 fluorine pyrrole bacterium acid amides 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 21, after fluorine pyrrole bacterium acid amides and active component B are composite, can effectively prevent and treat downy mildew of garpe, 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.
Application Example ten trifluoro pyrrole bacterium acid amides and active component B and the composite control pear scab test of pesticide effectiveness thereof
This test arrangement, at Xianyang, Shanxi province suburban area, is investigated the pear scab state of an illness before medicine, in the dispenser for the first time of state of an illness initial stage, once, dispenser is 2 times altogether in dispenser in every 7 days.Within after dispenser 10 days, 20 days, 45 days for the second time, investigate respectively disease index and calculate preventive effect.Experimental result is as follows:
Table 22 fluorine pyrrole bacterium acid amides and active component B and the composite control pear scab test of pesticide effectiveness thereof
As can be seen from Table 22, after fluorine pyrrole bacterium acid amides and active component B are composite, can effectively prevent and treat pear scab, 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.
After through different local throughout the country tests, draw, the preventive effect that can effectively prevent and treat the Common Diseases such as powdery mildew, downy mildew, epidemic disease, rust, anthracnose, gray mold, scab, net blotch, glume blight, leaf mold, ring spot, rice blast, banded sclerotial blight, shot hole, leaf spot, spot defoliation, anthrachose of grape after fluorine pyrrole bacterium acid amides and dithianon, cyprodinil, captan, phosethyl-Al, tpn, bromothalonil compounded is all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
