Garlic pest control method
First, the symptoms of victimization
Garlic larvae eat garlic bulbs as larvae, causing the bulbs to rot. The aboveground leaves are yellow, wilting and even dead. Pulling out the victim can be found in maggots. The damaged garlic skin is yellow-brown and rot. The garlic is drilled into holes by the larvae. The incomplete, incomplete, garlic cloves are exposed, burst, and accompanied by foul smell. Victims are easily removed and disconnected.
Second, the characteristics of occurrence
Garlic pods can begin to damage before the winter, phlegm overwintering after entering the winter, in the following year the pupa emerged into adults. Adult eggs are produced in the earth seams or clumps under the garlic roots and even in the leaf sheaths. Eggs can be hatched into larvae after 5-7 days, and the larvae can crawl to garlic for food. Garlic maternal period is the peak period of egg hatching of garlic sprouts.
Third, prevention and control measures
1. Artificial trapping of adult worms. You can use brown sugar, vinegar, and water in a ratio of 1:1:2.5 to prepare a trapping liquid, and add sawdust and trichlorfon and mix well, and put it into a trap basin to trap and kill adult insects in a piece of garlic. In this way, killing adults before spawning can have a multiplier effect.
2. Kill adult worms. In the adult spawning period, 1.8% of epimedin was sprayed to kill adult eggs and eggs, sprayed once every 7 days, and sprayed twice to reduce the number of adult ovipositors and reduce the damage.
3. Topdressing nitrogen and sulfur fertilizers. Combined with water and topdressing, the nitrogen and sulphur fertilizers that have a deterrent effect on garlic sprouts can reduce the damage.
4. Pharmaceutical irrigate root. In the field, when the garlic sprouts were found in the field, they could be irrigated with phoxim and water, or irrigated before the rain. Severely irrigated every 10-15 days.
