Embodiment 1

[0014] The method of coating urea with imidacloprid: first pour 100 kg of urea granules into a clean container, then add 1 kg of 10% imidacloprid wettable powder, and stir until the powder is evenly coated on the surface of urea granules.

[0015] How to use: The amount of urea used after coating is 11 kg per mu, and it is applied before sowing cruciferous vegetable seeds. Sow seeds after application, and then cover them with rakes and rakes.

Embodiment 2

[0017] The method of coating urea with imidacloprid: first pour 1 kg of urea granules into a clean container, then add 1 kg of 10% imidacloprid wettable powder, and stir until the powder is evenly coated on the surface of urea granules.

[0018] How to use: The amount of urea used after coating is 11 kg per mu, and it is applied before sowing cruciferous vegetable seeds. Sow seeds after application, and then cover them with rakes and rakes.

Embodiment 3

[0020] The method of imidacloprid-coated compound fertilizer: first put 100 kg of compound fertilizer granules into a clean container, then slowly add 1000 ml of 5% imidacloprid EC while stirring, and strive to make each compound fertilizer granule absorb evenly To the liquid medicine, to achieve even compound fertilizer granules.

[0021] How to use: The amount of compound fertilizer after coating is 11 kg per mu, and it is applied to the transplanting ditch before the cruciferous vegetables are transplanted, and then the ditch is covered with soil and watered.

Abstract

The invention relates to a method for controlling striped flea beetles and applying fertilizer, and relates to a method for controlling cruciferous vegetable pests. Controlling striped flea beetles and applying fertilizer can be achieved by using imidacloprid coated urea or compound fertilizer particle and scattering the coated urea or compound fertilizer particles to a cruciferous vegetable field. The weight ratio of imidacloprid to urea in the imidacloprid coated urea particles is 1:100-1:1. The weight ratio of imidacloprid to compound fertilizer in the imidacloprid coated compound fertilizer particles is 1:100-1:1. The coated compound fertilizer particles and urea particles can be used before transplanting or seeding of vegetables, and can also be used after seedling emergence or transplanting of live seedlings. During application of the method, no backpack sprayer is needed for leaf spraying of pesticides for controlling the stripped flea beetles, so that vegetable pollution by the pesticides is lessened. In addition, the method is effective in controlling the striped flea beetles, and has the controlling effect equal to or superior to that of the conventional methods.

Description

technical field [0001] The invention relates to a method for preventing and controlling cruciferous vegetable pests, in particular to a method for preventing and controlling flea beetle. Background technique [0002] The flea beetle is a worldwide pest that mainly damages cruciferous vegetables. The adult flea beetle lives on the ground and feeds on the leaves of cruciferous vegetables; the larvae live in the soil and feed on the underground parts of plants . The flea beetle was first discovered in Europe and North America. For a long period of time, this insect has become a serious pest that damages vegetables. The flea beetle is mainly distributed in Liaoning, Zhejiang, Jiangsu, Hunan, and Fujian in China. , Guangdong, Guangxi, Sichuan, Yunnan, Guizhou, Gansu, Shaanxi, Taiwan and other places, almost all provinces in the country. After the 1990s, the structure of agricultural industries in various parts of my country was adjusted, and the area of ​​vegetable planting was...
