Embodiment 1

[0027] A raw material formula of a pesticide mixture for preventing and treating corn borer consists of:

[0028] Composition Weight %

[0029] Abamectin 1%

[0030] Beta-Cypermethrin 4%

[0031] Emulsifier 10%

[0032] Methanol 25%

[0033] Xylene 60%

[0034] Put avermectin, beta-cypermethrin, methanol and xylene into the stirring ax according to the weight percentage of the above-mentioned raw material formula, fully stir until clear and transparent, and then add emulsifier. The emulsifier is prepared by mixing triphenylethyl polyoxyethylene ether, calcium dodecylbenzenesulfonate, styrene and ethanol in a weight ratio of 35:35:15:15. Stir for 4 hours. After standing still, the product can be obtained by packing.

Embodiment 2

[0045] A raw material formula of a pesticide mixture for preventing and treating corn borer consists of:

[0046] Composition Weight %

[0047]Amainamectin 1.5%

[0048] Beta-Cypermethrin 3.75%

[0049] Emulsifier 12.75%

[0050] Methanol 30%

[0051] Xylene 52%

[0052] Put abamectin, beta-cypermethrin, methanol and xylene into the stirring ax according to the above weight percentage, fully stir until clear and transparent, and then put into the emulsifier. The emulsifier consists of a mixture of triphenylethyl polyoxyethylene ether, calcium dodecylbenzenesulfonate, styrene and ethanol in a weight ratio of 35:35:15:15. Stir for 4 hours. Pack after leaving standstill, can obtain embodiment 2 product.

[0053] Comparative example: application number is the formula disclosed in 02100024.7, abamectin, beta-cypermethrin, emulsifier, methyl alcohol, xylene are mixed and prepared by weight ratio 0.4: 1.6: 10: 28: 60 with the above-mentioned preparation method, and emulsifiabl...

Embodiment 3

[0063] A raw material formula of a pesticide mixture for preventing and treating corn borer consists of:

[0064] Composition Weight %

[0065] Amainamectin 2%

[0066] Beta-Cypermethrin 3%

[0067] Emulsifier 15%

[0068] Methanol 40%

[0069] Xylene 40%

[0070] Put abamectin, beta-cypermethrin, methanol and xylene into the stirring ax according to the above weight percentage, fully stir until clear and transparent, and then put into the emulsifier. The emulsifier consists of a mixture of triphenylethyl polyoxyethylene ether, calcium dodecylbenzenesulfonate, styrene and ethanol in a weight ratio of 35:35:15:15. Stir for 4 hours. Pack after leaving standstill, can obtain embodiment 3 products.

[0071] Comparative example: Abamectin, beta-cypermethrin, emulsifier, methanol, and xylene were mixed and prepared by the above-mentioned preparation method in a percentage by weight of 3:1.5:10.5:25:60, and the emulsifiable concentrate was prepared as a contrast agent.

Abstract

The invention relates to pesticide mixture agent for preventing ostrinia nubilalis and the application thereof. The pesticide mixture agent is missible oil mainly prepared by abamectin, high-efficientalpha cypermethrin, emulsifier, methyl alcohol and dimethylbenzene. The emulsifier is the mixture of triphenethyl phenmethyl polyoxyethylene ether, calcium dodecylbenzene sulfonate, benzene and alcohol solvent. By weight percentage, raw materials of the mixture agent are as follows: 1.0-2.0% of abamectin, 3.0-4.0% of alpha cypermethrin, 9-16% of emulsifier, 25-40% of methyl alcohol and 40-60% ofdimethylbenzene. When in use, the pesticide mixture agent is diluted with water at 600-900-fold and sprayed in maize bell-mouth period, tasseling stage and husking period in the fields, and thus can prevent ostrinia nubilalis, effectively reduce the population quantity of the ostrinia nubilalis and obviously reduce wood-boring steams, tassel and spike buds.

Description

technical field [0001] The invention relates to a pesticide mixture for preventing and treating corn borer, in particular to a pesticide mixture for preventing and controlling corn borer and a preparation method thereof, belonging to the field of pesticides. Background technique [0002] Corn borer is the main pest of corn in my country. The insect mainly damages corn by boring stems, tassels and ears, seriously affecting the yield and quality of corn, reducing corn yield by more than 30%, and causing huge losses. At present, the control of corn borer is still dominated by the application of chemical pesticides, mainly organophosphorus pesticides such as parathion, phoxim and acephate, and biological pesticides such as Bacillus thuringiensis. Organophosphorus pesticides have disadvantages such as high toxicity to humans and animals, large residues, and difficult degradation. After use, the food safety level of corn will be greatly reduced. Although Bacillus thuringiensis is...
