Embodiment 1

[0013] Preparation of 60% etofenprox·thiodicarb water-dispersible granule 100kg:

[0014] Take by weighing 10kg of etofenprox former powder, 50kg of thiodicarb, 5kg of wetting agent sodium alkylbenzenesulfonate, 10kg of dispersant naphthalene sulfonate formaldehyde condensate, 25kg of filler white carbon black, and fully weigh the above raw materials Mix evenly, after granulation by spray granulation method, the finished product of 60% etofenprox thiodicarb water dispersible granule is obtained, and the preparation 2000~2500 times of the preparation according to the above ratio has a control effect on vegetable cabbage caterpillar in 92 % above, better than single use.

Embodiment 2

[0016] Preparation of 60% polyethrin · thiodicarb wettable powder 100kg:

[0017] Weigh 20kg of etofenprox raw powder, 40kg of thiodicarb, 7kg of wetting agent calcium alkylbenzenesulfonate, 15kg of dispersant NNO, and 18kg of filler white carbon black. Fully mix the above-mentioned raw materials that have been weighed, pulverize them in an airflow mill, and then mix them evenly to obtain the finished product of 60% etofenprox-thiodicarb wettable powder. The preparation according to the above ratio is 2000-2500 times liquid The control effect on vegetable cabbage caterpillar is more than 95%, which is better than single use.

Embodiment 3

[0019] Preparation of 60% etofenprox-thiodicarb suspension concentrate 100kg:

[0020] Weigh 13kg of the original powder of etofenprox, 50kg of thiodicarb, 8kg of dispersing wetting agent nonylphenol polyoxyethylene ether, 2kg of antifreeze propylene glycol, 0.9kg of thickener xanthan gum, 3kg of silicone defoamer, filler 23.1kg of water. The above-mentioned raw materials that have been weighed are fully mixed and evenly ground, and then mixed evenly after being ground and pulverized by a sand mill to obtain a finished product of 60% etofenprox-thiodicarb suspension concentrate. The control effect of 2000-2500 times of the preparation prepared according to the above ratio on vegetable cabbage caterpillar is more than 90%, which is better than single use.

[0021] The preparation method of the wettable powder, water dispersible granule, emulsion in water and suspending agent of the insecticide composition containing etofenprox according to the present invention is as follows: ...

Abstract

The invention discloses an etofenprox containing insecticide compound, which includes three constituents of effective active ingredient, assistant, and a carrier. The effective active ingredient includes one of the etofenprox, the thiodicarb, and the diafenthiuron, and the weight percentage is 1-99 percent, the mixing ratio in weight of the etofenprox to the thiodicarb when being mixed is between 1:80 and 30:1, and the mixing ratio in weight of the etofenprox to the diafenthiuron when being mixed is between 1:75 and 30:1. When the invention is in use, the pollution is less, the production cost is low, the preventing effect is excellent, and the duration is long. After the etofenprox, the thiodicarb, and the diafenthiuron are compounded, the common toxicity coefficient is more than 100 obviously, the synergistic effect is obvious, and the safety is high.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to an insecticide composition containing etofenprox which is used in combination with quick-acting ingredients and sustained-acting ingredients. Background technique [0002] At present, there are many agricultural insecticides, and etofenprox is one of them. It is mainly used to prevent and control insect pests of crops. It has good safety, wide insecticidal spectrum and outstanding effect. Containing only one active ingredient, there are often defects in varying degrees in the control of agricultural pests and pest mites. After continuous use, pests and pest mites are prone to develop drug resistance, and frequent use will cause environmental pollution. However, the insecticide and acaricide of two or more active components are mixed into a mixed component insecticide and acaricide, which can effectively overcome the above shortcomings. At the same time, using the synergistic effect...
