Examples
Embodiment 1
[0033] See Tables 1 and 2 for the determination of the measured virulence index of tomato spot disease.
[0034] Table 1 The measured toxicity index of single agents such as thiazolone and cymoxanil to tomato spot disease
[0035]
[0036] Table 2 Analysis of the results of determination of tomato spot virus force by compounding different ratios of thiamethoxam and cymoxanil
[0037]
[0038] The results showed that the control effect of thiamethoxam and cymoxanil on tomato spot disease was significantly improved, indicating that the compound ratio of the two had a significant synergistic effect on the tomato spot disease fungus between 1:10 and 10:1, and the co-toxicity coefficient All above 150, the synergistic effect is obvious.
Embodiment 2
[0040] Toxicity test of thiamethoxam and metalaxyl compounded on soft rot of Chinese cabbage, see Table 3-4 for details.
[0041] Table 3 Toxicity index of thiamethoxam and metalaxyl single agent on soft rot of Chinese cabbage
[0042]
[0043] Table 4 Analysis of the test results of soft rot virus in Chinese cabbage with different ratios of thiamethoxam and metalaxyl
[0044]
[0045] The results showed that the control effect of thiamethoxam and metalaxyl on Chinese cabbage soft rot was significantly improved, indicating that the compound ratio of the two had a significant synergistic effect on the tomato spot disease fungus between 1:10 and 10:1. The co-toxicity coefficients are all above 150, and the synergistic effect is obvious.
Embodiment 3
[0047] The test of thiamethoxam, qingkuling, and thiram paired with bean spot disease virus, the results are shown in Table 5-6.
[0048] Table 5 The virulence index of thiamethoxam, Qingkuling and thiram in bean spot disease measured, the mass ratio of Qingkuling and thiram is 1:1
[0049]
[0050] Table 6 Analysis of the results of the determination of carob spot virus potency in different ratios of thiamethoxam, Qingkuling and thiram. The mass ratio of Qingkuling and thiram is 1:1.
[0051] deal with
[0052]
[0053] The results showed that the control effect of thiamethoxamin, Qingkuling and thiram on bean leaf spot was significantly improved, indicating that the compound ratio of the two was between 1:10 and 10:1, which had a significant effect on bean leaf spot. Synergistic effect, the co-toxicity coefficient is above 120, and the synergistic effect is obvious.
