Problems solved by technology

The spinetoram currently sold on the market is 60 grams per liter of suspending agent, and the spinetoram has the disadvantages of high cost of use, increased resistance, and general duration of effect during use. Reasonable mixing of insecticides with the mechanism of action plays an important role in fully and effectively promoting spinosad and prolonging its service life
[0007] At present, the pesticide preparations with clothianidin as the active ingredient are mainly 20% clothianidin suspension concentrate. In the actual use process, the long-lasting effect is long, but the quick-acting effect is average and the cost of use is high; the insecticidal effect of biological sources is good. , the quick-acting effect is fast, but the long-lasting effect period is average. It is used year by year, and the resistance develops rapidly. The inventor unexpectedly found that the mixed use of clothianidin and biological sources has a significant synergistic effect, which can reduce the cost of use and slow down the pests. The role of resistance

The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 22% clothianidin emamectin benzoate suspension concentrate.

[0058] In this embodiment, the weight ratio of clothianidin and biological source insecticide can be changed between 1:40-40:1, and the total weight content of the two is still 22%, forming a new embodiment.

[0059] The formula is used to prevent and control rice leaf roller, the dosage per mu is 10g, diluted with 50kg of water and sprayed, the control effect is 90.2% after 7 days of application, and 92.6% after 14 days of application. The dosage of 8% emamectin benzoate EC is 30g per mu and the dosage of 20% clothianidin suspension is 15g...

Embodiment 3

[0061]Weigh 20% clothianidin, 10% spinosad, 3% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2425, 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone disinfectant Add foam agent s-29 and deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% clothianidin spinosad suspension.

[0062] In this embodiment, the weight ratio of clothianidin and biological source insecticide can be changed between 1:40-40:1, and the total weight content of the two is still 30%, forming a new embodiment.

[0063] The formula is used to prevent and control rice leaf roller, the dosage per mu is 8g, diluted and sprayed with 50kg of water, the control effect is 94.3% after 7 days of application, and 95.6% after 14 days of application. 20% clothianidin suspension concentrate 15g per mu and 2.5% spinosad suspension concentrate 80g per mu, use the same method, the control effect is...

Abstract

The invention discloses an insecticidal composition containing thiacloprid amide and a biogenic insecticide. The biogenic insecticide is selected from avermectin, emamectin benzoate, spinosad or spinetoram, and the ratio by weight of the thiacloprid amide to the biogenic insecticide is 1:40-40:1. The composition can be prepared into a dosage form which is agriculturally acceptable, such as water dispersible granules, wettable powder, a suspending agent, a dispersible oil suspending agent, a microcapsule suspending agent, missible oil or a micro emulsifier. The insecticidal composition has reasonable ingredients, great insecticide effect and low chemical cost. The activity and the insecticidal effect of the insecticidal composition are not just the simple sum of the activity and the insecticidal effect of all ingredients. Compared with the traditional single preparation, the insecticidal composition not only has remarkable insecticidal effect, but also has remarkable synergistic function, mitigates resistance generation, has small preparation residual quantity and high safety, does not pollute crops and meets the safety requirements of agricultural pesticide preparations. The insecticidal composition disclosed by the invention has better control effects on rice stem borers, vegetable plutella xylostella, beet armyworms, cotton bollworms and apple olethreutid.
