The high temperature in the winter and the spring, which aggravated the occurrence of garlic pests and diseases, was beneficial to the overwintering and spring damage of garlic sprouts. It is suggested that the garlic farmers should work harder and earlier on the prevention and control of garlic sprouts.
Symptoms of damage: Garlic grubs eat larva bulbs with larvae, cause the bulbs to rot, and the leaves above the ground show yellow, wilting and even death. 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 easy to pull out and pull off.
Occurrence characteristics: Garlic pods can cause damage before the winter, phlegm overwintering after entering the winter, and the pupa emerged into adult worms in March of the following year. Adult eggs are produced in the earth seams or clumps under the garlic roots or in the leaf sheaths. Eggs can be hatched as larvae and eaten for garlic after 5 to 7 days. Garlic maternal period is the peak period of egg hatching of garlic sprouts.
Control measures: According to the weather and the characteristics of garlic sprouts this year, the following effective prevention measures should be taken.
Artificial trapping of adult worms: Into the available March brown sugar, vinegar, water ratio of 1:1:2.5 dubbed lure, and add sawdust and trichlorfon mix, into the trap basin. Insect worms are concatenated into garlic. In this way, killing adults before spawning can have a multiplier effect.
To kill adult worms: Kill adult flies and eggs with 1.8% chitin 1000 times during the adult spawning period, once every 7 days, and spray twice. Reduce the number of laying eggs laid by the fly and reduce the damage.
Topdressing nitrogen and sulphur fertilizers: combined with watering topdressing nitrogen and sulphur fertilizers that have a deterrent effect on garlic sprouts to reduce the degree of damage.
Chemical control: In the field, if the infected plant is found to be infected with Garlic Sprouts, it may be treated with phoxim plus chlorphenirone or chlorpyrifos before flushing with water or irrigating the roots before rain. Severe blocks are treated again every 10 to 15 days.
