The use of agricultural physics measures: such as reasonable rotation, seed treatment, soil disinfection, grafting and disease prevention, high-temperature stuffy shed, Lianyungang light, and yellow-trap sex traps, can effectively control the occurrence of insect pests. If there are still pests and diseases, drug control must be carried out. Biopesticides are used first, followed by rational use of chemical pesticides. Commonly used biological pesticides mainly include: 1. Insecticides: BT biological pesticides (such as 1000 wins), 1.8 Aforein, 1.5-dimensional force, 1.8 insects light, 0.9 insects grams, Abade, family haha, NPV , cotton smoke Ling, to a young urea, inhibit Tai Bao, oxymatrine, green spirit, resveratrol. 2. Fungicides: Agricultural anti-120, Wuyisu, zithromycin, bacillus drug grams, agricultural streptomycin, neo-mycin 751 and so on. Scientific use of chemical pesticides: 1. The use of highly toxic, high-residue pesticides is strictly prohibited. 2. Select pharmaceuticals suitable for use with vegetables: phoxim, thosphos, dimethoate, trichlorfon, metalaxyl manganese zinc, cadmium, beta-aluminum, antivirus, fast-acting, acetaminophen, Tokamak spirit, virus, etc. 3. Strict implementation of pesticide safety standards. The State sets out, for all pesticides, the number of days used per mu per crop, the highest dose, the maximum number of applications, the method of application, and the number of days from the last application of harvest. In the control of pests and diseases can not be arbitrarily increased the amount of application and increase the number of applications and shorten the safety interval. 4. Select the appropriate pesticide formulation. The use of dusts and aerosols on protected vegetables should not only reduce the humidity in the shed, but also prevent the spread and pollution of germs. The varieties are: 6.5% moldewin, 5% chlorothalonil, 5% extinguish, 5% penicillin, and 45% chlorothalonil. 5. alternate rotation medication. Try to use pesticides of different types and formulations in alternation to avoid disease resistance. 6. Harvested vegetables, such as cucumbers, tomatoes, and peppers, must be harvested first and then applied.
