specific Embodiment approach

[0096] Specific embodiments: joint toxicity of different ratios of spirotetramat and imidacloprid

[0097] The present invention is further explained by the following examples, but the scope of the present invention is not limited to the following examples.

[0098] 1.1 Drugs to be tested

[0099] 95% spirotetramat (imidacloprid) and 95% imidacloprid (carbosulfan) were provided by Jiangsu Yangzhou Lvyuan Biochemical Co., Ltd.

[0100] 1.2 Sources of indoor test insects

[0101] Rice leaf rollers were collected from the field, and were reared indoors with rice seedlings until the third instar for testing. Indoor conditions: temperature (25±2)℃. The relative humidity is 65%±5%, and the photoperiod is 12 / 12h (L / D).

[0102] 1.3 single dose determination method

[0103] Using the rice stem dipping method, dig out robust and consistent rice plants at the mid-booting stage, wash them, cut them into 15cm-long connected rice stems, and dry them in a cool place until there is no w...

Abstract

The invention discloses a bactericidal composition containing imidacloprid and spirotetramat, a preparation method and application thereof. The insecticidal composition is characterized by containing imidacloprid, spirotetramat and other additives, wherein the weight ratio of imidacloprid to spirotetramat is 1:50-80:1. 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 imidacloprid and spirotetramat at home and abroad, so this invention is proposed.

Description

technical field [0001] The invention belongs to the field of agricultural chemicals, and relates to an insecticidal composition and application thereof, in particular to an insecticidal composition with imidacloprid and spirotetramat as main active components. Background technique [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 mixing of chemical insecticides and acaricides can expand the prevention spectrum, improve the control effect, prolong the application period, reduce the dosage, reduce the drug damage, reduce the residue, and delay the occurrence a...
