Pesticide composition containing copper succinate and benziothiazolinone

[0025] Example 1 Indoor Toxicity Determination Test of Copper Succinate Fatty Acid and Thiamidone Compound on Cucumber Downy Mildew Pathogen

[0026] Test method: refer to "Pesticide Indoor Bioassay Test Guidelines for Fungicides NY / T1156.3-2006", and use the plate leaf method.

[0027] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0029] Drug name and proportion (weight ratio)

[0030]As can be seen from Table 1, when copper succinate and thiamethoxamin are compounded in the range of 40:1 to 1:1 (by weigh

[0031] Example 2 Indoor Toxicity Determination Test of Copper Succinate Fatty Acid and Thiampidon Compound on Citrus Canker Pathogenic Bacteria

[0032] Test method: Refer to "Indoor Bioassay Test Guidelines for Pesticides and Fungicides NY / T1156.16-2008" and use the turbidity method.

[0033] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0047] The contents of the following substances are all percentages by weight: 20% copper succinate, 1% thiamethoxam, 6% sodium lauryl polyoxyethylene ether sulfate, 4% pull-off powder, 1% xanthan gum, Isothiazolinone 0.2%, C 10-20 Saturated fatty acid compound 0.1%, sorbitol 3%, deionized water make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a 21% copper succinate fatty acid thiamethondone suspension concentrate.

[0048] The above-mentioned 21% copper succinate fatty acid · thiamethondone suspension concentrate was used to control cucumber downy mildew. As can be seen from Table 3, 30 days E-E 0 The value is 22.95%, which shows that the combination of copper succinate and thiamethonin has a synergistic effect on cucumber downy mildew. At the same time, no phytotoxicity to cucumber was found after applying 21% copper succinate-thiamethondone suspension concentrate dur
