Abstract

The invention discloses a potato serious insect attack green prevention and control method. The method includes the following steps that in winter, a planting site is deeply ploughed by 25 cm to 30 cm, and eggs preparing for overwintering are killed through low temperature; before sowing, potato seeds and the planting site are disinfected; sowing is carried out in the mode of potato and mint intercropping, and mint belts are planted around the planting site; after sowing, steinernema is put in water and sprayed to the ground at dusk after raining; after greenhouse trialeurodes vaporariorum is found, artificially propagated encarsia formosa is released into the planting site; after garlic is mashed, water is added, and then the mixture is sprayed to potato branches and leaves. According to the method, a disinfector not polluting the environment is adopted in the whole planting process, no pesticide or insecticide with high toxicity is adopted, environmental friendliness is achieved, no environmental pollution is caused, the problems of pesticide standard exceeding, soil quality and environment affecting and the like are avoided, economic benefits are increased, and development of ecological planting is promoted.

Description

technical field [0001] The invention relates to the technical field of potato planting, in particular to a green prevention and control method for major potato pests. Background technique [0002] Insect pests are one of the important reasons that affect potato production. At present, the main pests that harm potatoes include potato tuber moth, ladybug, aphids and whitefly in greenhouse. These pests not only directly eat potato tubers, plants, etc., but also Carrying and spreading viruses, causing diseases, therefore, pest control is an important issue in the potato planting process. At present, these pests are generally killed by spraying pesticides, which may cause problems such as excessive pesticides and affecting soil quality and the environment. With the use of pesticides, the resistance of pests is gradually enhanced, and the amount of pesticides is increasing, which is not conducive to ecology. Planting development. Contents of the invention [0003] The purpose ...
