With what can maggots be destroyed?
Ground maggot is a general term for the larvae of Muscidae that harm crops and vegetables, also known as root maggots. So with what can maggots be wiped out? The editor will introduce to you:
1. What are the harmful characteristics of maggots?
The ground maggot mainly harms the bulbs and tender stems where the larvae gather in the lower parts of the ground, such as scallions, garlic and leeks. The newly hatched larvae first harm the base of the leaf sheath or the upper end of the bulb, and the spring and autumn mainly damage the underground young stems, causing the underground stems to rot and make the upper leaves yellow and die. In summer, the larvae move downwards and decay into the bulbs, the bulbs rot and the whole leek dies.
With what can the maggots be wiped out?
1. Agricultural prevention and control: do not use immature fertilizer before sowing, cover the soil deeply after fertilization, do not let seeds and fertilizers be exposed, use chemical fertilizer instead of sparse manure when topdressing, and ammonia can also reduce maggot damage.
