Last Updated: 2024/11/22, 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 alfoptin EC and 20--30 ml of Chongmanguang EC are selected.

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.
