Embodiment 1

[0022] Weigh spinosyn and Zhongbuwei and prepare spinosad and Zhongbucarb emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 1 for specific proportions.

[0023] The toxicity of spinosad and Zhongbuwei and its compound samples to cotton bollworm was determined by feed poisoning method, each treatment was repeated 3 times, and 30 heads were treated at each concentration, and the LC was used to 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0024] Table 1 Toxicity determination and co-toxicity coefficient of spinosad, zhongbucarb and their compound samples to cotton bollworm

[0025]

[0026] The data in the table shows that after the mixing of spinetoram and zhongbucarb, there is a synergistic effect on cotton bollworm, and the co-toxicity coefficients of the four ratios listed in the table are all greater than 120. The compounding of Dingwei h...

Embodiment 2

[0028] Weigh spinosyn and Zhongbuwei and prepare spinosad and Zhongbucarb emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 2 for specific proportions.

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

[0030] Table 2 Toxicity determination and co-toxicity coefficient of spinosad, Zhongbucarb and their compound samples against rice brown planthopper

[0031]

[0032]

[0033] The data in the table shows that the mixture of spinetoram and zhongbuwei has a synergistic effect on rice brown planthopper, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. The compounding of Dingwei has obvious synergist...

Embodiment 3

[0035] Weigh 5g of spinosad, 20g of butylcarb, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and mix the above raw materials according to the conventional method of preparing emulsifiable concentrate Mix in the kettle to form the ethyl spinosyn · Zhongbuwei emulsifiable concentrate whose main active ingredient weight percent content is 25%.

[0036] The sample that adopts embodiment 3 to carry out the field test of field control cotton bollworm in field, contrast agent is 60 grams per liter of ethyl pleosyn SC and 25% Zhongbuwei WP, and concrete consumption is shown in Table 3, and water consumption per mu is 30kg 3 days, 7 days, 14 days, and 28 days results were checked after the medicine. The test results are shown in Table 3:

Abstract

The invention discloses a synergistic insecticidal composition containing spinetoram and fenobucarb and an application thereof. In the synergistic insecticidal composition, the spinetoram and the fenobucarb are employed as main active components, wherein a weight ratio of the spinetoram to the fenobucarb is 0.1-80:0.5-80. The synergistic insecticidal composition can achieve a prevention and treatment spectrum expanding effect and a synergistic effect, is reduced in application cost, can be prepared into emulsion oil, wettable powders, micro-emulsions, emulsion in water, suspending agents and water dispersible granules, and is used for preventing various pests comprising lepidoptera pests, hemiptera pests, hymenoptera pests, coleopteran pests and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with spinosad and secbutacarb as main active ingredients and an application thereof. Background technique [0002] Spinetoram, the structural formula is: [0003] [0004] XDE-175-J is a new spinosad insecticide produced by Dow AgroSciences and has received the first global registration, it can effectively control important pests on fruit trees and nuts, especially on fruit trees One of the thorny main pests of the apple moth. It is mainly used to control Lepidoptera larvae, thrips and leafminers, etc. It has good control effects on diamondback moth, beet armyworm, leafminer, thrips, Spodoptera litura and pod borer. [0005] The chemical name of Fenobucarb is: 2-sec-butylphenyl-N-methylcarbamate. The structural formula is as follows: [0006] [0007] Zhongbucarb is a carbamate insecticide, which mainly poisons and kills pests by inhibit...
