Embodiment 1

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

[0023] The toxicity of tonamiprole, chlorantraniliprole and their compound samples to rice stem borer was determined by the 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 toxinpyran, chlorantraniliprole and their compound samples to rice stem borer

[0025]

[0026] The data in the table shows that the mixture of tonamirad and chlorantraniliprole 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. Therefore,...

[0028] Tonfenpyran and chlorantraniliprole were weighed and prepared in different proportions by conventional preparation methods to prepare tonamiprole·chlorantraniliprole 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 tolfenpyrad, chlorantraniliprole and their compound samples to rice leaf rollers, each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

Embodiment 3

[0034] Weigh 5g of fenpyran, 20g of chlorantraniliprole, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, add xylene to 100g, and put the above raw materials into Mix in a mixing tank to form tonfenpyrad-chlorantraniliprole emulsifiable concentrate whose main active ingredient is 25% by weight.

[0035] The samples prepared in Example 3 were used to carry out the field test of controlling rice leaf rollers in the field. The control agents were 15% chlorantraniliprole EC (EC) and 22% chlorantraniliprole SC (suspension concentrate). The specific dosages are shown in the 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 treatment. 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 chlorantraniliprole and an application, the synergistic insecticidal composition takes tolfenpyrad and chlorantraniliprole as main effective components, wherein the weight ratio of tolfenpyrad to chlorantraniliprole 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 chlorantraniliprole and an application thereof. Background technique [0002] Fenpyrad (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 Pow5.61. The structural formula is: [0003] [0004] The acute toxicity of the tonfenpyrad preparation is: oral LD50102 (male), 83 (female) mg / kg for rats; oral LD50104 (male), 108 (female) mg / kg for mice. 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 t...
