Embodiment 1

[0021] Weigh spinosyn and busidicarb and prepare spinosad and busicarb emulsifiable concentrate with a weight percentage of 30% of the main active ingredient by using conventional preparation methods in different proportions. See Table 1 for specific proportions.

[0022] Toxicity of spinosad, mixicarb and their compound samples to cotton bollworm was determined by feed poisoning method, each treatment was repeated 3 times, 30 heads were treated at each concentration, and LC was used. 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0023] Table 1 Toxicity determination and co-toxicity coefficient of spinosad, mixicarb and their compound samples to cotton bollworm

[0024]

[0025] The data in the table shows that after the mixing of pleocidin and busicarb, 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, so pleocidin and mixed Dicarb mixing has a...

Embodiment 2

[0027] Weigh spinosyn and busidicarb and prepare spinosad and busicarb emulsifiable concentrate with a weight percentage of 30% of the main active ingredient by using conventional preparation methods in different proportions. See Table 2 for specific proportions.

[0028] The rice stem dipping method was used to determine the toxicity of spinosad, mixed-dicarb 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:

[0029] Table 2 Toxicity determination and co-toxicity coefficient of spinosad, mixicarb and their compound samples against rice brown planthopper

[0030]

[0031] The data in the table shows that the mixture of spinetoram and busicarb 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. Dicarb mixing has a significant synergistic effect.

Embodiment 3

[0033] Weigh 5g of spinosad, 20g of mixicarb, 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 spinetoram-bufencarb emulsifiable concentrate whose main active ingredient weight percent content is 25%.

[0034] Adopt the sample that embodiment 3 is equipped to carry out the field test of field control cotton bollworm in field, contrast agent is 60 grams per liter of spinosad SC and 50% mixed carbamide EC, 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

Disclosed are a synergistic insecticidal composition containing spinetoram and dimethacarb and an application thereof. The spinetoram and dimethacarb are used as the main active ingredients of the insecticidal composition, and the weight ratio of the spinetoram to the dimethacarb is 0.1-80: 0.5-80. The insecticidal composition has the effects of expanding a prevention and control spectrum and synergizing, can be reduce the pesticide cost, and can be formulated into emulsion oil, wettable powder, microemulsion, water emulsion, suspending agent and water dispersible granules to prevent and control various pests such as lepidoptera, hemiptera, hymenoptera, coleoptera and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition and an application thereof, which mainly use spinosad and bandicarb as active ingredients. 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] Nitenpyram, chemical name: 3,4,5-trimethylcarb; N-methyl carbamic acid mixed xylyl ester, molecular formula: C 11 h 15 NO 2 , the structural formula: [0006] [0007] Mixedcarb has contact killing, stomach p...
