The larvae lurk in the soil and feed the bulbs, causing decay, and the leaves wilting until they die. Those with light hazards, poor plant growth and development, and a significant decrease in yield and quality. According to the author's investigation, serious land masses can occur, with up to 50% to 76% of the affected strains and 30% to 57% of the deaths, resulting in a 35% to 60% reduction in production, a deterioration of quality, and a reduction of more than 50%. Implementation of comprehensive prevention and control can effectively control its harm. First, choose peeling Use strong garlic seeds and peel garlic skin before sowing. This will not only shorten the emergence period of garlic, ensure that the seedlings are robust, but also shorten the rotting time, and effectively reduce the risk of root rot. Second, rotation Carry garlic and turn crops and do a good job of deep turning fertilizer. Garlic and wheat rotation can effectively reduce the number of insects. Autumn plough deep-turning, the use of fully decomposed organic fertilizer, fertilizer and garlic isolated, can effectively control the root cause damage. 三ã€Pharmaceutical seed dressing Place garlic seeds in a cool place, use 50% phoxim EC 100-150 ml, add 25 kg of water, and mix 200-250 kg of garlic. The seed dressing of pesticides shall be accompanied with sowing in order to ensure the control effect and avoid the occurrence of phytotoxicity. According to the survey, the use of pesticide seed dressing is 60%-73% lower than that of undressed seedlings. 4. Spread poisonous soil when planting With 5% phoxim granules 3-4 kg per acre, and 50-80 kg of fine soil mix well, evenly spread into the sowing ditch, and then sowing. It is safe and easy to use and has a good insecticidal effect. Fifth, chemical control Grasp the emergence of adults and larvae at the beginning of the timely use of chemical control. Available 2.5% trichlorfon powder 1.5-2 kg, applied to the plant base and surrounding soil, or 2.5% of 2.5% deltamethrin EC, 48% of 1500 times, 50% phoxim EC 2000 Liquid, into the sprayer, remove the nozzle spin water tablets, the drug droplets into the roots, once every 7-8 days, even 2-3 times. The 9-11 am application effect is the best, killing insects and killing larvae. The control effect is up to 95%.
