Embodiment 1

[0014] 1) Trichlorfon mixed with soil: mix 40g of trichlorfon with the surface soil, cultivate it at the base of the trunk 5cm, and then cultivate the soil in a conical shape with a height of 20cm and a radius of 30cm at the bottom;

[0015] 2) After the beetle lays eggs, manually scrape off the eggs and kill the larvae;

[0016] 3) 30 days before the harvest of Huajuhong, inject 1.5mL imidacloprid liquid per centimeter trunk diameter.

Embodiment 2

[0018] 1) Trichlorfon mixed with soil: mix 50g of trichlorfon with the surface soil, cultivate it at the base of the trunk 5cm, and then cultivate the soil in a conical shape with a height of 20cm and a radius of 30cm at the bottom;

[0019] 2) After the beetle lays eggs, manually scrape off the eggs and kill the larvae;

[0020] 3) 30 days before the harvest of Huajuhong, inject 1.5mL imidacloprid liquid per centimeter trunk diameter.

Embodiment 3

[0022] 1) Trichlorfon mixed with soil: mix 60g of trichlorfon with the topsoil, cultivate it at the base of the trunk 5cm, and then cultivate the soil in a conical shape with a height of 20cm and a radius of 30cm at the bottom;

[0023] 2) After the beetle lays eggs, manually scrape off the eggs and kill the larvae;

[0024] 3) 30 days before the harvest of Huajuhong, inject 1.5mL imidacloprid liquid per centimeter trunk diameter.

[0025] By cultivating soil or mixing medicine to cultivate soil, the spawning position of pests can be significantly improved and the eggs can be relatively concentrated, which reduces the difficulty of manually scraping eggs and killing larvae, and improves the control efficiency at the same time.

Abstract

The invention provides a method for preventing and controlling pomelo tree planting insect pests, which belongs to the field of plant disease and insect pest control, and comprises the following steps: before the beetle lays eggs, mix the soil with trichlorfon and cultivate the soil: mix the trichlorfon with the topsoil, cultivate it on the base of the trunk 5 cm, and then Conical soil, the height is 20cm, and the bottom radius is 30cm. After the beetle lays eggs, the eggs are manually scraped off and the larvae are killed by hooking. 30 days before the harvest of Huajuhong, inject 1.5mL of imidacloprid liquid per cm trunk diameter. The invention can improve the spawning position of the star beetle and make the distribution of the eggs relatively concentrated, which reduces the difficulty of manually scraping the eggs and killing the larvae, and improves the control efficiency at the same time, and the pesticide residues in the fruit are always within the safe range. There was no significant effect on the active ingredients of citrus red (naringin, anacardin).

Description

technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to a method for planting plant diseases and insect pests in Huazhou grapefruit trees. Background technique [0002] In order to reduce the harm of certain pests to crops, some means are artificially adopted, which is called pest control. [0003] At present, various pests are hunted and killed by light trapping and manual killing. In the past, pests were controlled by methods such as manual hooking and white painting, but some pests lay eggs at the base of tree stems, and trees are often killed due to incomplete hooking; The main trunk of the pomelo tree is not obvious, and there are many branches at the base. In addition to the erosion of rainwater, the effect of whitening the trunk is not obvious. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the defects that pests cannot be completely controlle...
