Application Example 11 Gentrin Knotweed P.E and active component B and compositely prevent and treat the sigatoka test of pesticide effectiveness.
This test arrangement is in Pubei County, Guangxi, Shaanxi Province, and investigation sigatoka disease index before medicine, in the dispenser of disease initial stage of origination, 3 days, 10 days, 20 days investigation disease indexes after dispenser also calculate preventive effect.Result of the test is as follows:
Table 18 Gentrin Knotweed P.E and active component B and compositely prevent and treat the sigatoka test of pesticide effectiveness
As can be seen from Table 18, Gentrin Knotweed P.E and active component B composite after effectively can prevent and treat sigatoka, through applicant test find Gentrin Knotweed P.E and active component B composite after also effectively can prevent and treat banana freckle, control efficiency is all higher than 97%, 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, Gentrin Knotweed P.E and the composite rear preventive effect to Common Diseases such as the powdery mildew in various crop, white rot, scab, rust, smut, false smut, leaf spot or banded sclerotial blights of active component B are all more than 97%, be better than single dose preventive effect, synergistic effect is obvious.
