Embodiment Construction

[0012] 1.1 Drugs to be tested

[0013] 93% of sulfoxaflor and 97% of cypermethrin are provided by Qingdao Hailier Pharmaceutical Group.

[0014] 1.2 Test target

[0015] Wheat aphids were collected from the field population of the wheat experimental field of Qingdao Agricultural University, and wingless adult aphids of the same individual size were selected for testing.

[0016] 1.3 Test steps

[0017] 1.3.1 Liquid preparation

[0018] Dissolve the original drug with acetone first, and mix the appropriate amount of the two original drugs into 5 different ratios according to the results of the preliminary experiment, and then use acetone to dilute each treatment into 5 series of concentration gradients for use. The ratios of the active ingredients of the five sulfoxaflor and cypermethrin in different proportions were 14:6; 12:8; 10:10; 8:12; 6:14 respectively and were diluted into 5 series of concentration gradients for use.

Abstract

The invention relates to an insecticide compound which belongs to the field of pesticide compound. In the invention, nitrile sulfluramid and cypermethrin are taken as the active ingredients of the insecticide compound. The mass ratio of the two active ingredients is (1-40):(40-1), preferably (5-24):(24-5), and optimally (10-15):(5-10). The total weight percent of the active ingredients in the insecticide compound is 1%-80%, and preferably 20%-50%. The rest is allowed and acceptable auxiliary ingredients in the pesticide. According to a known method, the insecticide compound can be prepared into missible oil, concentrate emulsion, micro-emulsion, water dispersible grain and suspending agent. After the nitrile sulfluramid and cypermethrin, as the active ingredients, are compounded into the insecticide compound at a certain ratio, the insecticide compound has an obviously enhanced effect of preventing and controlling sucking pests, such as plant hoppers, aphids, aleyrodids, leafhoppers, and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing sulfoxaflor and cypermethrin. Background technique [0002] The rice planthopper is one of the main pests that harm rice production in southern my country and the middle and lower reaches of the Yangtze River. Among them, the brown rice planthopper and the white-backed planthopper are intermittent large-scale pests. Adults and nymphs gather at the base of rice plants to suck juice, causing Rice plants are yellow and dry, stems become soft or rotten and lodging. Brown rice lice are the most serious damage. According to statistics, the damage area in 2005 and 2006 was about 250 million mu. Generally, the loss of rice is 5-10%, and the rice yield is reduced by 10-20% in a major occurrence year, and some heavy fields lose 40-50%, or even no harvest. The main damage of SBPH is that adults and nymphs become poisonous bodies after suc...
