Description

technical field [0001] The invention relates to the field of crop insecticides, in particular to an agent for removing maggots from leeks. Background technique [0002] Leek is a vegetable that the general public and ordinary people like very much. However, the current leek plantation is difficult due to stubble fall, and continuous cropping has been repeated year after year, resulting in decreased soil fertility, serious pests and diseases, decreased yield and poor quality of leek. What's more serious is that in recent years, there have been reports of poisoning incidents caused by eating leeks. The main reason is that during the peak period of leeks entering the market in spring and summer, it is also the period when leek maggots and other pests are concentrated in the underground of leeks. In the underground soil, general pesticides are difficult to kill them, so leek farmers use methamidophos, monocrotophos and other high-residue and highly toxic organophosphorus pestic...

However, the current leek planting is difficult due to the difficulty of stubble, and repeated cropping for years, resulting in decreased soil fertility, serious pests and diseases, decreased yield and poor quality of leeks

What is particularly serious is that in recent years, there have been reports of poisoning incidents caused by eating leeks. The main reason is that during the peak period of leeks entering the market in spring and summer, it is also the period when leek maggots and other pests are concentrated in the underground of leeks. In the underground soil, general pesticides are difficult to kill them, so leek farmers use methamidophos, monocrotophos and other high-residue and highly toxic organophosphorus pesticides mixed with water to kill leek maggots, because a large amount of organophosphorus pesticides will be killed by leeks. The root absorbs and remains in the leek, so it is not easy to be washed off simply, and people will be poisoned after eating it.

This not only affects the vegetable baskets of citizens, but also affects the economic benefits of vegetable farmers
