[0020] Indoor toxicity test of a pesticide composition containing bifenhydrazate and fenpropathrin to apple red spider

[0021] Test insects: apple red spider.

[0022] Test agents: All were provided by Shaanxi Thompson Biotechnology Co., Ltd.

[0023] Experimental design: Adopting the method of soaking the leaves first and then catching the insects, soak the fresh apple leaves of the same size without any medicine in the prepared medicine solution for 5 seconds, then take them out, dry them naturally, put them in the insect breeding box, and then pick them up. The 3rd instar larvae were reared at 25°C. Each treatment was repeated for 3 times. The number of test insects used in each repetition was 20. A blank control was also set up. The number of dead insects was checked at 72 hours, and the mortality and corrected mortality were calculated. Obtain the virulence regression equation and calculate the LC 50 value. If the control mortalit...

Abstract

The invention relates to a pesticide composition comprising the main effective components of bifenazate and fenpropathrin, and a suitable amount of addition agents and filling materials are added into the pesticide composition. The pesticide composition is characterized in that the weight percentage of the bifenazate to the fenpropathrin as the effective active components is 1-40:1-20; and after the bifenazate and the fenpropathrin are compounded, the pesticide composition has obvious synergistic action and continuous control effect, saves time and labor, enlarges an insecticidal spectrum, treats insects and acarid in a combined mode and has higher activity on fruit trees, vegetables, cotton acarid, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition containing bifenazate and fenpropathrin as effective active ingredients for preventing and controlling crop mites. technical background [0002] Bifenazate (bifenazate) chemical name: 3-(4-methoxybiphenyl-3-yl) isopropyl carbazate, molecular formula: C 17 h 20 N 2 o 3 , bifenazate is a new selective foliar spray acaricide effective against all life stages of mites. It has ovicidal activity and rapid knockdown activity on adult mites, and has minimal impact on predatory mites, and is very suitable for comprehensive management of harmful mites. Not poisonous to plants. [0003] Fenpropathrin, chemical name: α-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropanecarboxylate, [0004] Structural formula: [0005] Molecular formula: C 22 h 23 NO 3 . [0006] Fenpropathrin is a kind of pyrethroid insecticide with broad insecticid...
