Problems solved by technology

At present, chemical pesticides are mainly used in the prevention and treatment of Western flower thrips, but at present, chemical pesticides cannot fundamentally affect the hermaphroditism and parthenogenesis of Western flower thrips, and lead to the generation of pesticide resistance of Western flower thrips. The problem of thrips’ resistance to pesticides is very serious, and spraying pesticides will also cause pesticide residues, which is not conducive to the healthy consumption of the public

Embodiment 1

[0087] With the comprehensive control method of the present invention as test group 1, spray as test group 2 with 60g / L ethyl spinosad suspension (U.S. Dow AgroSciences Co., Ltd.), clear water is as a control group, and carry out Chinese and western medicine in the coriander planting process in greenhouse. The control of flower thrips is repeated 3 times (i.e. 3 plots) for each treatment. On the 1st day, the 3rd day and the 7th day after the treatment, the population of each treatment is investigated, and 5 points of each plot are sampled, and each point is randomly selected. Investigating the population of Thrips occidentalis on 10 coriander plants. Statistical insect population reduction rate and corrected control effect. The insect population reduction rate and corrected control effect are calculated according to the following formula:

Abstract

The invention discloses a prevention and control method for coriander frankliniella occidentalis. The method comprises the steps that 1) preparation is completed before planting; 2) a silicon fertilizer is applied, and the applying method is that in the early stage of coriander planting, the silicon fertilizer with the concentration of 2-10 kilograms per mu is used for flushing, applying and dropirrigation; 3) a nitrogenous fertilizer is applied, the nitrogenous fertilizer is one or more of 1.0%-3.0% of urea solution, 0.5%-1.5% of ammonium bicarbonate solution, 0.3%-1.0% of sal volatile solution and 0.1%-1.0% of hartshorn, and the fertilizer is sprayed to portions outside roots; 4) artificial isolation is adopted. The method is used for preventing and controlling the frankliniella occidentalis, pesticide residues on coriander are reduced, coriander quality is improved, safety threat of pesticide to creatures is reduced, and chemical pesticide resistance generation of the frankliniellaoccidentalis is reduced.
