Problems solved by technology

[0005] At present, the prevention and control of whitefly pests in tea trees is mainly the method of spraying chemical drugs. Although it has played a certain role in prevention and control, it has also brought pesticide residues on tea leaves, pollution to soil, air, water sources, and other environments. Disadvantages such as dead natural enemies
In particular, the special use of tea makes it more demanding on the use of pesticides. In order to prevent harm to people, the use of poisonous and long-lasting drugs has been banned.

Test results show that the plant-derived preparation for controlling piercing-sucking type tea pests disclosed by the invention has a high effect of controlling the piercing-sucking type tea pests, does not pollute the environment, is low in cost, simple in preparation process, safe, direct, environment-friendly and high-efficiency, and saves cost.

Description

technical field [0001] The invention relates to the field of agricultural prevention and control, in particular to a botanical preparation for preventing and treating tea tree piercing-sucking pests, a preparation method and an application method thereof. Background technique [0002] Whitefly pests widely occur on various crops such as tea trees, vegetables, and fruit trees. The damage is quite common and the losses caused are very serious, and its control is relatively difficult. It is listed as a major worldwide pest and can be called a plant pest. The stubborn disease in the disease has been paid more and more attention. Tea tree piercing-sucking pests refer to piercing-sucking insects of the family Amiptera of the order Homoptera, including tea tree blackthorn whitefly and whitefly. Adults of both sexes have wings, and the body and wings are covered with wax powder. [0003] my country's plant resources are very rich, and nearly a thousand species of plants contain in...
