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...

Abstract

The invention discloses a synergistic insecticidal composition containing tolfenpyrad and metaflumizone and an application, the synergistic insecticidal composition takes tolfenpyrad and metaflumizone as main effective components, wherein the weight ratio of tolfenpyrad to metaflumizone is 0.1-80:0.5-80. The insecticidal composition has effects for enlarging the prevention and cure scope and synergia, and the medication cost is reduced, and the synergistic insecticidal composition can be prepared to a missible oil, a wettable powder, a microemulsion, an emulsion in water, a suspending agent and a water dispersible granule, and the synergistic insecticidal composition can be used for preventing and treating various pests such as Lepidoptera, Homoptera, Hymenoptera, thysanoptera and coleopteran.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic insecticidal composition containing tolfenpyrad and metaflumizone and application thereof. Background technique [0002] Tolfenpyrad (Tolfenpyrad), chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl]-methyl}-1H pyrazole -5-Carboxamide, off-white solid powder, density (25°C): 1.18g / cm, vapor pressure (25°C): <5×10Pa. Solubility (25°C): water 0.037mg / L, n-hexane 7.41g / L, toluene 366g / L, methanol 59.6g / L. Partition coefficient (n-octanol / water) (25°C): log Pow 5.61. The structural formula is: [0003] [0004] The acute toxicity of the tonfenpyrad preparation is: oral LD50 for rats 102 (male), 83 (female) mg / kg; oral LD50 for mice 104 (male), 108 (female) mg / kg. The acute percutaneous toxicity is relatively low, with LD50>2000mg / kg for rats and mice. Moderately irritating to rabbit eyes and skin. [0005] Fenpyramid is a new type...
