Occurrence species and control methods of garlic pests
In garlic production in Dali City, there are two main insect pests, namely Liriomyza huidosa and Pholiophora leonii. Liriomyza sativae mainly damages garlic at the early stage of growth (3- 6 leaves), and Oniophoris allii damages garlic at the whole growth stage, especially at the middle and late stages. In the control, Liriomyza huidobrensis can be used when garlic has 3--4 leaves. According to the situation, 1.8% of avermectins 10--15 ml/mu, 1.8% of Efodin EC and 20--30 ml/mu of Chongmanguang EC are selected for control. The harm of Liriomyza punctata to garlic can be controlled effectively by controlling it twice every 10 days, and the average control effect is 90%EX2. The harm of Liriomyza punctata to garlic can be controlled by controlling it with 40% dimethoate emulsifiable concentrate 100ml/mu, 30% phoxim emulsifiable concentrate 80ml/mu or chrysanthemum ester pesticide when the number of 100 plants (larvae) reaches more than 20, once every 7 days, and continuously controlling it for 2 - 3 times. In addition, other pests that occur on garlic in our state include thrips, aphids and other pests. Because the harm to garlic is light, when controlling the main pests, it has a concurrent effect on these pests. Therefore, it is generally unnecessary to control them separately.

After harvest, cut off the whisker root, cut off the stem disk, soak 1 Mel for 2 days, scrub and peel, wash and dry and cut into thin slices, steam and blanch for 5 minutes. The far-infrared drying device is used, the loading capacity is 5 ℃ per square meter, 6 kg per square meter, the temperature is 65 ℃-75 min, 6 min 7 hours, and when the moisture content of the dry product reaches 5%-8%, it is packed and stored immediately.

The garlic is caught early after the spring tube.
The temperature of autumn sowing garlic in 2006 was higher than that in previous years from planting to the first ten days of December, which accelerated the growth of garlic seedlings. Before winter, garlic grows to 710 leaves (the best seedling age for overwintering is 57leaves), the phenomenon of seedlings has appeared, and the mother has been rotten, resulting in insect pests. As a result, garlic grows too fast, resulting in poor nutrition accumulation, reduced stress resistance, slow return to green after years, serious disease and low potential for high yield. Garlic should complete a series of growth processes in spring, such as turning green, vigorous growth of seedlings, elongation of garlic vines, expansion of garlic and so on. On the basis of applying sufficient base fertilizer to garlic, spring
