Embodiment 1
[0021] Example 1 The control effect of thiazinamide composition on rice blast
[0022] A single compound or composition is dissolved in an organic solvent to prepare a 1000 mg / L mother solution. According to the pretest of biological activity determination, a certain amount of the above mother solution was diluted with 0.1% Tween 80 to prepare the required concentration. During the determination, spray the medicinal solution on the potted rice plants first, then inoculate the pathogenic bacteria, and after moisturizing and cultivating for 24 hours,
[0023] Place them in a greenhouse for cultivation, and measure the percentage of plant foliage infection after a certain period of time. Using Abbot's formula,
[0024] Convert percentages to efficacy.
[0025]
[0026] Theoretical control effect (%)=x+y-xy / 100
[0027] x is the control effect of active component A when the concentration is a, and y is the control effect of active component B when the concentration is b. C...
Embodiment 2
[0032] Example 2 Control effect of thiazilamide composition on cucumber downy mildew
[0033] A single compound or composition is dissolved in an organic solvent to prepare a 1000 mg / L mother solution. According to the pretest of biological activity determination, a certain amount of the above mother solution was diluted with 0.1% Tween 80 to prepare the required concentration. During the test, the cucumber plants were basically at the 4-leaf stage, and the incidence of downy mildew was investigated before the first medicine. A potted test of cucumber downy mildew was carried out with the thiazilamide composition, and a corresponding single agent and a blank control were set up, and a hand-held sprayer was used for conventional constant spraying, and 10 plants were sprayed with each agent, and sprayed once and then sprayed again 7-10 days after spraying once. 10-14 days after the second spraying, survey all the leaves of each plant, record the total number of surveyed leaves ...
Embodiment 3
[0049] Example 3: Field test on wheat powdery mildew of thiazinil composition
[0050] The field test of wheat powdery mildew was carried out with the composition, and a corresponding single dose and a blank control were set up, and a plot of 30m was set up for each dose. 2 . A knapsack sprayer was used for regular constant spraying, and the test was sprayed once at the booting stage and the early stage of flowering, before the drug and 7-10 days after the second spraying, and each treatment was sampled at five points, 50 plants at each point, and all leaves were investigated for each plant. Record and investigate the total number of leaves and the number of diseased leaves, and calculate the disease index and control effect according to the following grading method.
[0051] Leaf Grading Method:
[0052] Level 0: no disease
[0053] Level 1: The connected area of disease spots accounts for less than 1% of the entire leaf area;
[0054] Grade 3: The connected area of d...
