Embodiment 1

[0017] Example 1 In order to understand and verify the control effect of spinosyn and pyraclofen in different ratios on pest mites, the inventors used spinosyn and pyraclofen in different ratios to control the 3rd instar larvae of beet armyworm and tea green leafhopper. Nymphs were tested for virulence indoors for 72 hours. According to the different proportions of spinosad and pyraclofen in Table 1 and Table 2, different concentrations were prepared, and the indoor effect test was carried out to determine the co-toxicity coefficient. The test results are shown in Table 1 and Table 2. According to the calculation of the co-toxicity coefficient formula of Sun Yunpei method, when the co-toxicity coefficient is greater than 100, it means that there is a synergistic effect.

Embodiment 2

[0025] Example 2 Mix 1 kg of spinosad, 9 kg of fenpyroxan, 1.5 kg of styrylphenol polyoxyethylene polyoxypropylene ether, 3 kg of naphthalenesulfonic acid formaldehyde condensate, N-methyl fatty amido taurate 1 kg, 3 kg of ethylene glycol, 0.1 kg of octanol, and 81.25 kg of water are mixed evenly, and sanded by a sand mill for 50 minutes, and then 0.15 kg of xanthan gum is added, and stirred evenly to obtain 10% spinosad * pyraclofen suspension agent.

Embodiment 3

[0026] Example 3 10 kilograms of spinosad, 25 kilograms of pyraclofen and 2.5 kilograms of styrylphenol polyoxyethylene ether polyoxypropylene ether, 3.5 kilograms of naphthalenesulfonic acid formaldehyde condensate, N-methyl fatty amido taurine 1.5 kg of salt, 3 kg of ethylene glycol, 0.15 kg of tributyl phosphate, 53.85 kg of water, stirred evenly and sanded for 50 minutes, then added 0.5 kg of polyvinyl alcohol and stirred evenly to obtain a 35% spinosad * fenpyroxan suspension concentrate.

Abstract

The invention relates to a pesticide compound which comprises the following components by weight percent: 0.3 percent to 10 percent of spinosad, 1 percent to 30 percent of fenpyroximate, 3 percent to 20 percent of additive, and the balance of excipient, wherein the weight ratio of the spinosad and the fenpyroximate is 1:1 to 1:100. The pesticide compound can be used for preparing environmental protection formulations such as micro-emulsion, water emulsion, suspension concentrate and the like, is used for controlling lepidopterous pests, dipterous pests, homopteran pests and mites generated on crops, in particular to beet armyworms and high-resistance tea leafhoppers, and has obvious synergistic action.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing spinosyn and pyraclofen. Background technique [0002] In recent years, crop diseases and insect pests have a trend of continuous large-scale rapid occurrence and development. In order to ensure a good agricultural harvest, the actual level and dosage of pesticides used by farmers are constantly increasing, which directly leads to the increasingly prominent problem of pesticide resistance of pests. and the focus of attention of pesticide manufacturers. [0003] Spinosyn, also known as spinosad (Spinosad), is a macrolide pollution-free and efficient biopesticide extracted from the fermentation broth of Saccharopolyspora spinosa. Spinosad has a novel mode of action, which can continuously activate the target insect acetylcholine nicotinic receptor, but its binding site is different from that of nicotine and imidacloprid. Spinosad can also affect GABA ...
