Example Embodiment
[0021] Example 1:
[0022] Tolfenpyrad and cyfluthron were weighed and formulated into Tolfenpyrad·Meflufluzone EC with the main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. The specific ratio is shown in Table 1.
[0023] Toxicity of Tolfenpyrad, Meflufluzone and their compound samples to Chilo suppressalis were determined by feed poisoning method. Each treatment was repeated 3 times, each concentration treated 30 heads, with LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient:
[0024] Table 1 Toxicity determination and co-toxicity coefficient of Tolfenpyrad, cyfluthron and their compound samples against Chilo suppressalis
[0025]
[0026] The data in the table shows that the mixture of Tolfenpyrad and Mehalofluron has a synergistic effect on Chilo suppressalis, and the co-toxicity coefficients of the four ratios listed in the table are far greater than 120. Therefore, Tolfenpyrad and Cyanoflurz...

[0027] Example 2:
[0028] Tolfenpyrad and cyfluthron were weighed and formulated into Tolfenpyrad·Meflufluzone EC with the main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. The specific ratio is shown in Table 2.
[0029] The toxicities of Tolfenpyrad and Meflufluzone and their compound samples to Cnaphalocrocis medinalis were determined by the rice stem dipping method. Each treatment was repeated 3 times, using LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient:
[0030] Table 2 Toxicity determination and co-toxicity coefficient of Tolfenpyrad, cyfluthron and their mixed samples to Cnaphalocrocis medinalis
[0031]
[0032] The data in the table shows that the mixed mixture of tolfenpyrad and fenflurzone has a synergistic effect on the rice leaf roller, and the co-toxicity coefficients of the four ratios listed in the table are far greater than 120, therefore Fipronil mixing has a significant s...
Example Embodiment
[0033] Example 3:
[0034] Weigh 5g tolfenpyrad, 20g cyanflurzone, 4g calcium dodecylbenzene sulfonate, 3g phenethylphenol polyoxyethylene ether, add xylene to 100g, and mix the above raw materials according to the conventional method of preparing emulsifiable concentrates Mix in a kettle to form Tolfenpyrad·Meflufluzone EC with a main active ingredient weight percentage of 25%.
[0035] The samples prepared in Example 3 were used for field trials of controlling rice leaf rollers. The control agents were 15% Tolfenpyrad EC (emulsifiable concentrate) and 22% Cyhaloflozone SC (suspending agent). The specific dosage is shown in Table 3. , The water consumption per mu is 30kg, and the results will be checked 3 days, 7 days, 14 days and 28 days after the medicine. Use clear water as a blank control, and the test results are shown in Table 3:
[0036] Table 3 Field test results of Example 3 samples on rice leaf roller
[0037]
[0038] It can be seen from Table 3 that Example 3 has excell...
