[operating instructions]
A agricultural control
By selecting disease-resistant varieties, adopting a set of agricultural measures such as fitness cultivation and rational rotation, the resistance of vegetables will be improved and the pests and diseases will be reduced. Including: 1 selection of disease-resistant varieties according to local conditions. 2 seed treatment and seed bed high temperature disinfection. 3 timely sowing, according to the local weather forecast and the characteristics of vegetable varieties, select the appropriate sowing date. 4 The use of greenhouses or greenhouse nursery, nutrition seedlings nursery, the use of high-temperature rooting and early hardening seedlings to prevent seedlings, can reduce seedling disease, seedlings robust and enhance resistance to disease. 5 Deeply plowing the soil preparation, applying sufficient basal fertilization, and reasonable rotation and intercropping. Deep plowing can promote the decay of diseased plants and fallen leaves under the soil and turn the underground germs and insects to the surface, which is unfavorable for wintering and reduces the source of disease and insects. 6 Improve cultivation methods and strengthen field management. Control the ecological conditions of greenhouses and greenhouses to prevent the occurrence of diseases. 7 Graft prevention and control of soil-borne diseases.
B physical control
1 The use of black light can seduce a variety of pests; use sun tannins for insecticidal sterilization; use shade nets to prevent sickness. 2 Use yellow boards, blue boards or white boards to trap and kill pests; use silver gray film or silver-grey nets, hanging strips to repel pests. 3 Shaizhong, soaking seeds and other high temperature treatment of seeds; high-temperature killing pests in the soil; high temperature stuffy shed to inhibit the disease.
C biological control
The first is the use of predatory natural enemies such as ladybugs, grasshoppers, pupas, and falcons, and the use of parasitic natural enemies such as the Trichogramma, as well as the use of predatory spider mites; second, the use of Bacillus thuringiensis (Bt) , Beauveria bassiana, Metarhizium anisopliae, nuclear polyhedrosis virus (NPV), avermectin antibiotics, microspore, and other protozoan insecticides; thirdly, use of warfarin alcohol solution, Sophora flavescens, bitter buckwheat, tobacco Alkali, di-alkali and other plant-derived pesticides control a variety of pests. Fourth, in terms of disease prevention and control, the CMV satellite vaccine S52 and the tobacco mosaic virus vaccine N14 can be used to prevent viral diseases, and jinggangmycin, polyoxin, Qingfengmycin, and Nongkang 120 can also be used. B0-10 (wuyimycin), agricultural streptomycin and neomycin and other agricultural antibiotics prevent diseases.
D Rational use of chemical pesticides
Pollution-free vegetables do not use chemical pesticides. Chemical pesticides are an effective means of preventing and controlling vegetable diseases and insect pests. In particular, epidemic diseases and pest outbreaks are effective prevention and control measures. The key is how to use them scientifically and rationally, and it is necessary to prevent and control diseases and insect pests. It is also necessary to reduce pollution and control pesticide residues in listed vegetables within the allowable range. To achieve reasonable use of chemical pesticides, attention should be paid to the following points: First, be familiar with the types of pests and diseases, understand the nature of pesticides, and achieve the right medicine; Second, strictly implement the relevant national regulations, prohibit the use of highly toxic and high residual pesticides; third is the use of high efficiency and low ( Medium) Poison, low residue pesticides.
