Embodiment Construction

[0031] A kind of method of killing underground pest grub of the present invention comprises the following steps:

[0032] ① Determine that the plant is infested by grubs: the leaves on the ground part of the plant are wilted and the tops are drooping;

[0033] ②Check that the soil moisture content after being infested by grubs is 15%-20%;

[0034] ③Detect the temperature at 13°C-18°C at a soil depth of 10 cm after being infested by grubs;

[0035] ④Prepare the microwave irradiation machine for standby: the microwave irradiation machine has a housing 1, the bottom surface of the housing 1 is provided with a through hole 3, and the microwave transmitter 2, the soil detector 6 and the controller 7 are installed in the housing 1, and the microwave transmitter 2 and the soil detector The devices 6 are respectively connected with the controller 7, and the microwave irradiation cavity 4 is installed at the bottom surface of the housing 1 and the through hole 3. The surrounding walls...

Abstract

The invention discloses a method for killing grubs of underground pests, which comprises the following steps: (1) determining that the plants are infected with pests; (2) testing if the moisture content in the soil infected with the grubs is between 15 and 20 percent; (3) testing if the temperature of soil infected with the grubs at a depth of 10 centimeters is between 13 and 18 DEG C; (4) preparing a microwave irradiator for later use; (5) killing the grubs by horizontal and intermittent irradiation with microwaves; (6) starting the microwave irradiator, setting the microwave frequency at 915MHz, and irradiating intermittently for 3 to 6 times, 60 to 90 seconds each time, wherein the time interval between each two times of irradiation is 40 to 60 seconds; and (7) detecting the grub killing effect, namely sieving soil which is 5 centimeters above the irradiated area with a sieve with an aperture of 5 millimeters, collecting grubs, needling the grubs and seeing if the grubs react with bare eyes and determining the grubs are die if they give no reaction. The pure physical method kills grubs without polluting soil, water and the like.

Description

technical field [0001] The invention relates to an agricultural insecticidal method, which is a method for killing underground pest grubs. Background technique [0002] Grubs are the collective name for the larvae of the Scarabidae, also known as the white soil silkworm. Grubs are recognized as soil-dwelling pests that are difficult to control at home and abroad. They have many types, wide distribution, miscellaneous feeding habits, hidden life, strong adaptability, and different lengths of life history. Grubs harm a variety of crops and economic crops. Its seeds, roots, tubers and seedlings are worldwide underground pests with great harm. There are currently three main methods of killing grubs: Physical methods of black light booby trapping. It is to use black light to trap the adult beetles of grubs to reduce the reproduction of grubs, but it has no killing effect on the existing grubs in the soil. Biological natural enemy control law. Commonly used natural enemies...
