Below be that ternary built wetting powder of the present invention is used to prevent and treat the field control effectiveness test of downy mildew of garpe.
1, test medicine: get 34%wt ternary built wetting powder, 44%wt ternary built wetting powder, 54%wt ternary built wetting powder that embodiment 1,2,3 makes;
2, contrast medicament: 50%wt folpet wetting powder
The 80%wt mancozeb wettable powder
3, for studying thing: grape;
4, controlling object: downy mildew of garpe (Plasmopara uiticola);
5, experimental scheme:
(1) 24%wt ternary built wetting powder;
(2) 34%wt ternary built wetting powder;
(3) 54%wt ternary built wetting powder;
(4) 50%wt folpet wetting powder
(5) 80%wt mancozeb wettable powder;
(6) contrast sprays clear water.
6, application method
Adopt the BP-16 type to bear the manual sprayer spraying, convert water 50Kg for every mu;
Control efficiency adopts following disease index to calculate, and test data is through variance analysis, with the significance of difference of LSR method check control efficiency.
Disease index=(∑ (the sick numbers of sheets at different levels * relative level numerical value)/investigate total number of sheets * 9) * 100
Control efficiency=((check plot disease index-treatment region disease index)/check plot disease index) * 100
7, result of the test
Result of the test is seen following two forms.
Table 1 (mancozeb+folpet+white urea cyanogen) ternary built wetting powder is prevented and treated the downy mildew of garpe result of the test
Table 2 (mancozeb+folpet+white urea cyanogen) ternary built wetting powder is prevented and treated the downy mildew of garpe test effect
The result shows: 44% and 54% ternary built wetting powder has the better prevention effect to downy mildew of garpe, and preventive effect is respectively 81.18% and 79.46%; Two kinds of contrast pharmacy control efficacies are lower slightly, but good than the preventive effect of 34% ternary built wetting powder.The results of analysis of variance shows that 44% ternary built wetting powder and contrast medicament there are differences significance, not there are differences significance with the preventive effect of 54% ternary built wetting powder, but saves cost, and environmental pollution is few.
