Method for killing garlic maggots in garlic growth period

Abstract

The invention discloses a method for killing garlic maggots in the garlic growth peroid. The method comprises the following steps of: (1) finding out garlic infected by garlic maggots; (2) determining the distribution range of the garlic maggots; (3) manufacturing a microwave irradiator, wherein the microwave irradiator comprises a garlic overground-part protection cavity, wherein two sides of the protection cavity are respectively connected with a shell, a microwave emitter and a controller are arranged in the shell, a bottom plate of the shell is provided with a through hole, the lower partof the outer wall of the bottom plate of the shell is provided with an irradiation cavity, a reflective plate is arranged between the outer side wall of the irradiation cavity and the bottom plate ofthe shell, and two sides of the bottom of a tapered body of the protection cavity are respectively provided with a microwave leakage-proof brush; (4) selecting the irradiation frequency of the microwave irradiator to be 450MHz; (5) inserting the bottom end of the irradiation cavity of the microwave irradiator into soil where the garlic grows; (6) starting up for irradiating; and (7) detecting thetemperature of the irradiated soil to be less than 50 DEG C. The method disclosed by the invention is used for killing the garlic maggots, has no any harm to environments, such as people and livestock, soil and the like and ensures that the killing rate of the garlic maggots reaches 100 percent.

Description

technical field [0001] The invention relates to an agricultural insecticidal method, which is a method for killing garlic maggots during the growth period of garlic. Background technique [0002] Garlic maggots are important underground pests harmful to garlic production, parasitic in the bulbs at the roots of garlic and in the surrounding soil. Because the garlic bulbs are relatively shallow from the ground, the area 10 cm around and 5 cm deep around the garlic is the area where garlic maggots are seriously harmful. Garlic maggots eat the bulbs, resulting in partial rot of the bulbs, yellowing and cracking of the garlic petals, and loss of edible value. At the same time, the leaves appear poor growth, wilting and yellowing, and even the whole tree dies. According to statistics, the harm rate of garlic maggots can generally reach more than 30%, and in severe cases, it can reach 50%-70%, and even lead to extinction. At present, chemical pesticides are commonly used in agric...

AI Technical Summary

Problems solved by technology

At present, chemical pesticides are commonly used in agricultural production to kill garlic maggots, and the pesticides that can kill garlic maggots are all highly toxic pesticides. These highly toxic pesticides are also absorbed by garlic while killing garlic maggots, directly causing drug residues in garlic increase, which poses a great threat to human health

Therefore, in order to improve the safety of food, those skilled in the art have provided the root sprinkling ash deworming method, sweet and sour liquid trapping and killing method, biological method, but these methods all have heavy workload, low efficiency, high input cost, killing garlic Poor effect of maggots and other deficiencies

Therefore, the current method of killing garlic maggots is still to use highly toxic pesticides
