Embodiment 1

[0025] A kind of compound pesticide for preventing and treating tardigrade gnats of chives, the active ingredient is compounded from the original drug phoxim (volume percentage) and the original drug Kung Fu (volume percentage), take 30kg of commercially available phoxim with a content of 97% , 70kg of Kungfu with 70% content, 10kg of emulsifier 0201 and 600kg of N,N dimethylformamide are added to the reaction kettle successively, stirred for 60 minutes to make it mix evenly, after filtering, packaging into finished products is the prevention and treatment of the present invention. Compound Pesticides of Tardigrade Chives.

Embodiment 2

[0027] Get 50ml of the finished product pesticide compounded in Example 1, mix it with water according to the volume ratio of 1:1000, apply the method of root irrigation of leeks in one mu of land at night or on cloudy days, until the first crop of leeks is harvested The percentage of diseased leeks observed at harvest was 18%.

Embodiment 3

[0029] A kind of compound pesticide for preventing and treating tardy-eyed fungus of leek, is compounded by former drug phoxim (volume percentage) and former drug Kungfu (volume percentage), gets commercially available content and is phoxim 50kg of 97%, 70 50kg of Kung Fu, 10kg of emulsifier 0201-B and 690kg of N, N dimethylformamide were added to the reaction kettle in turn, stirred for 60 minutes to make it evenly mixed, and after being filtered, packaged into finished products, which is the prevention and treatment of the present invention. Compound Pesticides of Tardigrade Chives. Take 50ml of finished pesticide, mix it evenly with water according to the volume ratio of 1:1000, apply the pesticide to the root of one mu of leeks at night or on cloudy days, and observe the proportion of diseased leeks when the first crop of leeks is harvested The percentage is 10%.

Abstract

The invention discloses a compound pesticide capable of preventing and treating bradysia odoriphaga. The compound pesticide is compounded by active compounds phoxim and lambda cyhalothrin. A field efficacy trial proves that the insecticidal efficacy of the pesticide on bradysia odoriphaga larva can reach about 95%; the insecticidal speed can be obviously improved; the rate for generating the drug resistance by injurious insects is reduced; the prevention and treatment effects are enhanced; the production cost is reduced; and the targets of reducing the cost and increasing income by peasants are facilitated.

Description

technical field [0001] The invention relates to a pesticide and insecticide, in particular to a compound pesticide for preventing and treating tardigrade mosquitoes, that is, a phoxim-gongfu compound. Background technique [0002] Chive maggots, commonly known as chive maggots, belong to the order Diptera, the family Oculomidae, and the genus Bradyphagia. They are important vegetable pests in northern my country. They mainly harm leeks, green onions, onions, shallots, garlic and other lily vegetables. Among them, leeks suffered the most. Chive tardigrade mosquitoes have adults, eggs, larvae, and pupae, and the larvae gather in the bulbs and tender stems of the leek. The newly hatched larvae first damage the base of the leek sheath and the upper end of the bulb. In spring and autumn, the young stems of leeks are mainly caused to rot, causing the leaves of leeks to wither and die. In summer, the larvae move downward and bore into the bulbs. In severe cases, the bulbs rot and...
