This kind of pest is very common in the main producing areas of garlic, so what kind of pesticide should be used to treat this pest when it occurs?

I. treatment of garlic maggots

After the temperature continues to rise in April, garlic maggots will begin to wreak havoc in garlic producing areas, especially after rainy days, the harm of garlic maggots will be aggravated. If it is not prevented in time, the quality of garlic will decline, loose cloves and red garlic will affect the income of garlic farmers. Timely prevention can effectively reduce diseases, improve the quality of garlic and increase the commercial performance of garlic.

The main chemical control measures are as follows: 0.5 kg dimethoate emulsion for 3 kg of water before sowing, and 100 kg garlic cloves after dilution. Can also be used every 667 square meters with trichlorfon powder 1.5 kg ~ 2 kg, 25 kg of fine dry soil, scattered in the ditch for soil disinfection. During the adult occurrence period, 50% dichlorvos or 50% phoxim 1000 times solution was sprayed to kill the adult. During the larval stage, the roots were irrigated with garlic maggot or 48% Lesbon EC 1500 times, 52.25% Fangdile EC 1500 times, 50% phoxim 1500 times or 90% trichlorfon 1000 times, once every 7 to 10 days, two or three times in a row.

II. Planting of garlic

Garlic originated in Central Asia and the Mediterranean region. It was introduced to China during the Han Dynasty. Now it has been widely cultivated in China. The main production areas are Shandong, Jiangsu, Henan, Sichuan, Shaanxi and so on. At present, the total output of garlic in China ranks first in the world. The sowing period of garlic is generally carried out from late September to early October every year. When planting garlic, it is necessary to apply sufficient base fertilizer, topdressing in the seedling stage, flower stem extension period and garlic expansion period, and generally apply special compound fertilizer for garlic. In addition, in all periods after garlic sowing, the soil should be kept hydrated and free from stagnant water until watering is stopped 5 days before harvest.

The above is some relevant knowledge about garlic planting. When planting garlic, we should patrol the fields, observe carefully, and control it in time after the emergence of garlic maggots, so as not to reduce production.
