Orange disease and pest prevention and control method

Abstract

The invention relates to the technical field of disease and pest prevention and control of fruit trees, and particularly relates to an orange disease and pest prevention and control method. The methodcomprises the following steps: preventing and controlling soil-borne diseases, protecting natural enemies, removing diseased branches and diseased trees, performing prevention and control by using unmanned aerial vehicles to spray pesticide, and the like. Compared with conventional methods, the method disclosed by the invention adopts prevention methods of preventing and controlling soil-borne diseases, protecting natural enemies, and removing diseased branches and diseased trees, and combines with the prevention and control by using unmanned aerial vehicles to spray pesticide, so that diseases and pests are timely and comprehensively controlled, the use of chemical pesticides are reduced, the natural enemy and the ecological environment are protected, the pesticide residue of the fruitsmeets the standard, and the quality of the fruits is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of prevention and control of fruit tree diseases and insect pests, in particular to a method for preventing and controlling diseases and insect pests of citrus. 【Background technique】 [0002] Citrus has been planted on a large scale in the south, and it is a pillar industry in the rural areas of the main production areas in southern my country. The planting management technology has become mature, but the production and management mode of large-scale citrus is extensive, and the control of diseases and insect pests is still dominated by chemical pesticides. As a result, the use of pesticides has increased year by year, the ecological environment of orchards has been severely damaged, and the number of natural enemies has decreased. Diseases such as canker, phytophthora and other diseases are on the rise year by year, and the pesticide residues in the fruit exceed the standard, which affects the quality of t...

Problems solved by technology

[0002] Citrus has been planted on a large scale in the south, and it is a pillar industry in the rural areas of the main production areas in southern my country. The planting management technology has become mature, but the production and management mode of large-scale citrus is extensive, and the control of diseases and insect pests is still dominated by chemical pesticides. As a result, the use of pesticides has increased year by year, the ecological environment of orchards has been severely damaged, and the number of natural enemies has decreased. Diseases such as canker, phytophthora and other diseases are on the rise year by year, and the pesticide residues in the fruit exceed the standard, which affects the quality of the fruit.

In addition, the planting area is large, and most of the citrus orchards are hilly or mountainous. Only relying on backpack sprayers, pedal sprayers and motorized high-pressure spray guns for manual spraying operations, resulting in high labor intensity, high cost, serious pollution, and pesticide application. Personnel are also prone to pesticide poisoning incidents in hot and humid environments, and the speed of artificial spraying is slow, and rapid full-coverage spraying cannot be carried out in a short period of time, and the prevention and control effect is poor
