Embodiment 1

[0022] Weighing tonamiprole and metaflumizone were prepared in different proportions by conventional preparation methods to prepare tonamiprole-metaflumizone EC with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.

[0023] The toxicity of tonamiprole, metaflumizone and their compound samples to rice stem borer was determined by feed poisoning method. 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:

[0024] Table 1 Toxicity determination and co-toxicity coefficient of pyrenpyran, metaflumizone and their compound samples to rice stem borer

[0025]

[0026] The data in the table shows that the mixture of tonamifen and metaflumizone has a synergistic effect on rice stem borer, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. The mixture of vermizone has a significant syn...

Embodiment 2

[0028] Weighing tonamiprole and metaflumizone were prepared in different proportions by conventional preparation methods to prepare tonamiprole-metaflumizone EC with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0029] The rice stem dipping method was used to determine the toxicity of pyrenpyramid, metaflumizone and their compound samples to the rice leaf roller. Each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0031]

[0032] The data in the table shows that the mixture of tonamifen and metaflumizone has a synergistic effect on the rice leaf roller, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. The compounding of fluorflumizone has a significant synergisti...

Embodiment 3

[0034] Weigh 5g of pyrenpyran, 20g of metaflumizone, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, add xylene to 100g, and mix the above raw materials according to the conventional method of preparing EC mixing in a kettle to form tonamiprole metaflumizone emulsifiable concentrate whose main active ingredient is 25% by weight.

[0035] The sample prepared in Example 3 was used to carry out the field test of controlling rice leaf roller in the field, and the contrast agent was 15% pyrenpyrrole EC (emulsifiable concentrate) and 22% metaflumizone SC (suspension concentrate), and the specific dosage is shown in Table 3 , the water consumption per mu is 30kg, and the results will be checked in 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:

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...
