Problems solved by technology

Due to the use of existing conventional insecticides for many years, many agricultural pests have produced varying degrees of resistance to them, and their effects have declined. For example, the effects of monosultap and triazophos on controlling rice stem borers have dropped by about 1 / 3; On the one hand, imidacloprid and buprofezin can only control aphids and planthoppers, but are ineffective against lepidopteran pests

Embodiment 1

[0018] Weigh 5% tebufenozide, 50% monosultap, 3% sodium lignosulfonate, 3% NNO, 4% propylene glycol, 0.3% xanthan gum, 0.05% silicone defoamer, add water to 100% by weight share. Put the above raw materials into the high-speed mixer in turn according to the conventional method of preparing suspending agent, mix them into a coarse dispersion liquid, enter the colloid mill for fine grinding, and then enter the sand mill for ultrafine grinding, that is, 55% tebufenozide-killing Insect single suspension.

[0019] In this embodiment, the weight ratio of tebufenozide and monosultap can be 1:1~100 (for example 1:2, 1:8, 1:20, 1:30, 1:50, 1:70, 1:90 , 1:100), the total weight composition of the two is still 55%, forming a new embodiment; meanwhile, monosultap can also be replaced by buprofezin, forming a new embodiment.

Embodiment 2

[0021] Weigh 3% tebufenozide, 47% dimehypo, 5% lignosulfonate, 4% NO, 2% wetting penetrant T, 10% white carbon black, and diatomaceous earth to add up to 100% by weight. The above raw materials are conventionally prepared into wettable powder by superfine pulverization and mixing steps to prepare 50% tebufenozide-dimehypo wettable powder.

[0022] In this embodiment, the weight ratio of tebufenozide and dimehypo can be 1:1~100 (for example 1:2, 1:8, 1:20, 1:30, 1:50, 1:70, 1:90 , 1:100), the total weight composition of the two is still 50%, forming a new embodiment; Dimehypo can also be replaced by phoxim, forming a new embodiment.

Embodiment 3

[0024] Weigh 5% tebufenozide, 65% triazophos, 20% fatty alcohol polyoxyethylene ether, 0.2% xanthan gum, 0.02% organic silicon defoamer, add water to 100% by weight. Put the above raw materials into the high-speed mixer in turn according to the conventional method of preparing suspending agent to form a coarse dispersion, enter the colloid mill for fine grinding, and then enter the sand mill for ultrafine grinding to obtain 70% tebufenozide-three Azophos suspension.

[0025] In this embodiment, the weight ratio of tebufenozide and triazophos can be changed between 1:1~50 (example 1:2, 1:8, 1:20, 1:30, 1:50). The weight composition is still 70%, forming a new embodiment batch; triazophos can be replaced by chlorpyrifos simultaneously, forming a new

Abstract

The pesticide composition containing tebufenozide includes tebufenozide as the first active component and one kind of the second active component selected from monosultap, bisultap, triazophos, chlorpyrifos, trichlorfon, phoxim and other five kinds of pesticides. The present invention has reasonable component, low use, cost, and high pesticidal effect higher than the accumulation of its components.

Description

Technical field: [0001] The present invention relates to an insecticide. Background technique: [0002] It is well known that the regulation of ecdysone is very important in the growth, development and metamorphosis of holometabolous insects. The main component of ecdysone is 20-hydroxyecdysone. When the titer of 20-hydroxyecdysone increases, the epidermal cells of insect larvae will reorganize, and by tightly combining with the ecdysone receptor protein, the receptor protein will be activated, resulting in a large amount of protein synthesis, and the new upper epidermis and cuticle will be continuously secreted. Tebufenozide insecticides are analogues of 20-hydroxyecdysone. After being eaten by larvae, it interferes or destroys the original hormone balance in the insect body, so that new deformities and new skins continue to form in the old epidermis of the larvae. , resulting in blocked or abnormal growth and development of insects. Symptoms appear, the larvae stop feed...
