Problems solved by technology

[0002]In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the development of pest resistance produce
Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution.

specific Embodiment approach

[0097] Specific embodiments: joint toxicity of spirotetramat and bifenthrin in different proportions

[0098] 1.1 Drugs to be tested

[0099] 95% spirotetramat and 98% bifenthrin were provided by Jiangsu Changlong Chemical Co., Ltd.

[0100] 1.2 Sources of indoor test insects

[0101] The adults of citrus psyllids were collected from Murata japonica in urban green belts that were seldom sprayed, and reproduced with Murata japonica for 7 generations in a mesh room with an aperture of 0.45 mm.

[0102] 1.3 single dose determination method

[0103] The internationally unified drop method for the determination of rice planthopper toxicity was adopted. Accurately weigh the test agent, use a small amount of 25% acetone (because the psyllid adults are very sensitive to acetone, when using analytically pure acetone solution as a blank control, the mortality rate of the psyllid adults will exceed 30%, so dilute acetone with pure water Dilute to 25%) to dissolve the original drug, a...

Abstract

The invention discloses a fungicidal composition containing spirotetramat and bifenthrin, a preparation method and application thereof. The insecticidal composition is characterized by containing spirotetramat, bifenthrin and other additives, wherein the weight ratio of spirotetramat to bifenthrin is 1:50-70:1. It can be applied to the control of various pests of various crops. The composition is safe, environment-friendly, low in cost and good in effect. Indoor toxicity test and field efficacy test prove that the combination of these two compounds has obvious synergistic effect on target pests. And there is no report about the mixing of spirotetramat and bifenthrin at home and abroad, so this invention is proposed.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and relates to an insecticidal composition and its application, in particular to an insecticidal composition with spirotetramat and bifenthrin as main active ingredients and its application. technical background [0002] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the generation of pest resistance. Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution. Reasonable compounding or compounding of chemical insecticides can expand insecticidal spectrum, improve control effect, prolong application period, reduce dosage, reduce phytotoxicity, reduce residue, and delay the occurrence of drug resistanc...
