Embodiment 1
[0022] Combined Toxicity of Propyridine and Chlorpyrifos in Different Ratio
[0023] Weighing propargid and chlorpyrifos are prepared in different proportions by conventional preparation methods to prepare a propargid-chlorpyrifos suspension with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.
[0024] The toxicity of propargite, chlorpyrifos and their compound samples to citrus spider mite was determined by dipping slides. Each treatment was repeated 3 times, and each concentration was treated with 30 heads. 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:
[0025] Table 1 Toxicity determination and co-toxicity coefficient of citrus red spider mite, chlorpyrifos and its composite samples
[0026]
[0027] The data in the table shows that the mixture of propargite and chlorpyrifos has a synergistic effect on citrus spider mites, and the co-toxicity coefficients of the four ratios listed in the table are al...
Embodiment 2
[0029] Weighing propargid and chlorpyrifos were prepared in different proportions by conventional preparation methods to prepare propargid-chlorpyrifos emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.
[0030] The test method uses the method of soaking the leaves first and then inoculating the insects to determine the toxicity of propargite, chlorpyrifos and their compound samples to the brown planthopper. Each treatment is repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:
[0031] Table 2 Toxicity determination and co-toxicity coefficient of propargite, chlorpyrifos and their compound samples to brown planthopper
[0032]
[0033] The data in the table shows that the mixture of propargid and chlorpyrifos has a synergistic effect on brown planthoppers, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120...
Embodiment 3
[0035] Weigh 5g of propargite, 20g of chlorpyrifos, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and 100g of xylene, and put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrate. A propargite·chlorpyrifos emulsifiable concentrate with a main active ingredient weight percentage of 25% is formed.
[0036] Adopt the sample of embodiment 3 to carry out the field test of controlling citrus spider mite in field, contrast agent is 57% propargite EC and 2.5% chlorpyrifos EC, and concrete consumption is shown in Table 3, and water consumption per mu is 30kg, check 3 days after medicine , 7 days, 14 days, 28 days results, the test results are shown in Table 3:
[0037] Table 3 example 3 sample is to the field test result of citrus spider mite
[0038]
[0039] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on citrus spider mite, and has a relatively ...
