Pay attention to cultivation measures. First, we must use pest-resistant varieties; Second, we must rationalize crop rotation to reduce the accumulation of soil pests and diseases; Third, we must cultivate strong seedlings, close-up plants, clean gardens, reasonable irrigation and fertilization; Fourth, we must use seed disinfection and soil disinfection to kill bacteria; Light trapping, taste induction and other physical methods are used to trap and kill pests. For example: Yellow plate trap and kill aphids, whiteflies, spotted fly, etc.; light traps and other insects such as Lepidoptera and Scarab, such as Spodoptera litura; Plutella xylostella, Spodoptera litura, beet armyworm and other special attractants. Take biological control methods. Give full play to the control of pests in the field by natural enemies. First of all, choose a suitable cultivation method for the survival and reproduction of natural enemies to maintain the environment in which natural enemies live. Compared with garden cultivation methods, it is possible to maintain an environment conducive to the survival of natural enemies and achieve the goal of protecting natural enemies. Secondly, it should be noted that if pests are found in agricultural crops, they should avoid the use of chemical pesticides that have a large lethal effect on natural enemies, and biological pesticides should be preferred. Common types of biological pesticides include: BT biological insecticides and antibiotic insecticides, such as Liuyangmycin, avermectin, avermectin, agricultural anti-120, Wuyimycin, Jinggangmycin, Agricultural streptomycin and so on. Insect virus pesticides, such as the Austrian Green 1. Juvenile hormone pesticides, such as diflubenzuron (Enzoo), CPT. Plant-derived insecticides, such as oxymatrine, green wave and so on. Use low-toxic, low-residue chemical pesticides. In the late growth period of crops, when biological pesticides are difficult to control, such pesticides can be used for control. The applicable pesticides mainly include spinosad (vegetables), hits, tebufenozide (Merci, Asacarb), chlorfenapyr (dilution), fipronil (Frigid), and treflorum (Nongmonte) ), Chrysanthemum, Farmland, Deworming, Phoxim, Chlorpyrifos (XinNongBao, Le SiBen), Imidacloprid (BenXing), Broom-Breathing, Ank, Antivirus, Manganese Zinc (Ke Lu, Ke Dan), mold can spirit, procymidone, off the enemy force, pungentin, azoxystrobin (Shi Jiale), metalaxyl, can be killed, Dasheng M-45, carbendazim and so on. The use of highly toxic and high residue pesticides such as 3911, carbofuran, methyl 1605, methamidophos, and omethoate is strictly prohibited. The use of pesticides should pay attention to the use of pesticides, timely use of pesticides. Strictly control the concentration and the number of uses, using a reasonable method of drug use. Pay attention to the rotation of different types of pesticides to prevent pests from developing resistance. Strict implementation of pesticide use safety intervals.
