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.

Abstract

The invention discloses a composite for preventing and controlling an agricultural bacterial disease, and belongs to the technical field of plant protection pesticides. The composite comprises an active component A and an active component B, wherein the active component A is benziothiazolinone; the active component B is one or two of cymoxanil, qingkuling, yekuzuo, bismerthiazol, ethylicin, thiram, dioctyl divinyltriamino glycine, active ester, metalaxyl, chlorothalonil, dithiocyano-methane, bromine chlorine hydantoin, 2-bromine-2-nitryl-1,3-propylene glycol and moroxydine hydrochloride; the weight ratio of the active component A to the active component B is 1:100 to 100:1. The composite disclosed by the invention obtains the synergetic effect through the mixing of the benziothiazolinone and other bacterial medications and is used for agricultural production.

Description

technical field [0001] The invention belongs to the technical field of plant protection pesticides, in particular to a composition for preventing and treating agricultural bacterial diseases. Background technique [0002] Bacterial diseases can break out on a large scale in a short period of time and are difficult to control, causing large-scale production reduction of agricultural products and causing serious economic losses. [0003] At present, the medicaments for preventing and treating bacterial diseases in agricultural production are mainly two types of products, and copper preparations, including organic or inorganic copper preparations, are used in the largest amount. The other category is antibiotic products, including agricultural or medical antibiotics. The control effect of copper preparations is low, and a large amount of heavy metals are sprayed into the environment, polluting soil, water and food, causing environmental and food safety risks; the extensive use...
