The specific mode is as follows:
dissolving the above active components or compositions with acetone or water (the volume ratio of acetone to spray amount is equal to or less than 0.05), diluting with water containing 0.1% Tween 80, and preparing into desired concentration solution to be tested, and mixing the solutions to be tested according to a set proportion. And spraying the liquid to be detected on the disease host plants on a crop sprayer, and inoculating the disease after 24 hours. According to the disease characteristics, the disease plants which need to be subjected to temperature control and moisture preservation culture are inoculated and then placed in a climatic chamber for culture, and after the infection of the disease is completed, the plants are transferred into a greenhouse for culture. After the control is sufficiently ill, the percentage of leaf area of the pathogen-infected crop is determined and calculated using the Abbot formula to obtain the observed efficacy (W):
W＝(1-α/β)×100
wherein:
alpha: percent fungal infestation of the treated crop;
beta: percent fungal infestation of untreated (control) crops;
efficacy of "0" means that the level of infestation of the treated crop is the same as the level of infestation of the untreated control crop; efficacy of "100" means that the treated crop was not infested.
The expected efficacy (calculated efficacy) of the composition was determined using the Colby formula (see r.s. Colby, weeds, 1967, 15, 20-22) and compared to the observed efficacy.
E＝X+Y–XY/100
Wherein:
e: the expected efficacy (calculated efficacy in the tables below) when using the compositions of active components a and B at concentrations a and B, expressed as% of untreated control;
x: efficacy of active ingredient a at a concentration a was used, expressed as% of untreated control;
y: the efficacy of active ingredient B at a concentration B was used, expressed as% of untreated control.
When the observed efficacy value is greater than the calculated efficacy value, the composition is indicated to have a synergistic effect; when the observed efficacy value is equal to the calculated efficacy value, the composition is indicated to be additive; when the observed efficacy value is less than the calculated efficacy value, the composition is indicated to be antagonistic.
