How to completely eliminate root maggots

Root maggots is the collective name for the larvae of the Anthomyiidae family that harm the underground parts of crops and vegetables, also known as root maggots. So what can be used to eliminate root maggots?The editor will introduce it to you:

1. What are the harmful characteristics of root maggots?

Root maggots mainly gather as larvae in the underground bulbs and tender stems of green onions, garlic, Chinese chives and other plants to cause harm. Newly hatched larvae first damage the base of the leaf sheath or the upper end of the bulb. In spring and autumn, they mainly damage the underground young stems, causing the underground stems to rot, making the upper leaves turn yellow and die. In summer, the larvae move downward and bore into the bulbs; in severe cases, the bulbs rot and the entire clump of Chinese chives dies.

2. What can be used to eliminate root maggots?

1. Agricultural control: Do not use uncomposted fertilizer before sowing. After fertilizing, plow deeply to cover the soil so that seeds and fertilizer are not exposed. When topdressing, use chemical fertilizer instead of diluted manure, and applying ammonia water can also reduce maggot damage.

2. Chemical control: Spray pesticide once a week during the adult occurrence period, using 2.5% trichlorfon powder at 3-5 jin per mu or 90% trichlorfon at 1500 times dilution. You can also use 90% trichlorfon at 3-4 jin per mu when watering, and you can also spray the roots with 90% trichlorfon at 1000 times dilution.
