Prevention method of citrus yellowshoot

Abstract

The invention discloses a new prevention method of citrus yellowshoot. The method covers an insect-proof screen and a farm film to perform physical shield, and applies nutrient to supplement nutritionto plants, thus the plant immunity is improved, and orange tree can be prevented by adjusting PH value of soil. A sick tree is treated by chemical drug firstly while the root part is treated; the sick tree is performed with biological drug treatment by mixing concentrated solution prepared from azedarach, ailanthus, lettuce, cordate houttuynia, rheum officinale, mangnolia officinalis, folium artemisiae argyi and other Chinese herbal medicines and adding with plant growth hormone and inorganic salt synthesis agent. Through implementing the work, the sick tree of the orange tree is recovered, thus the citrus yellowshoot can be prevented, controlled, and treated; the method takes prevention mainly and treatment secondly, and combines prevention and treatment; the method is simple in operation, scientific and high-efficient in use, low in running cost, complete in prevention, good in treatment effect, and not easy to appear dust resistance and others.

Description

technical field [0001] The invention relates to the technical field of agricultural plant protection, in particular to a method for preventing and treating citrus huanglongbing. Background technique [0002] Citrus industry is the pillar industry of domestic fruit category. Guangxi's citrus planting area and output have ranked first in the country for many years. At present, the industry is facing difficulties due to the citrus Huanglongbing disease. Citrus huanglongbing is a disease caused by a Gram-negative bacterium that is limited to the phloem control department and belongs to Phloembacterium. The citrus psyllid is used as the transmission medium, which can be propagated by grafting and dodder. Whether the number of citrus psyllid can be effectively controlled in orchards is the key technology to control the outbreak of Huanglongbing in orchards. The fungus can also infect a variety of Rutaceae plants including Citrus, Citrus, Kumquat and Murata. [0003] Citrus huan...

Problems solved by technology

[0006] 1 Virus-free seedlings exist: one is incomplete detoxification, the other is genetic instability, and the third is inconsistent quality of seedling batches;

[0007] 2. Psyllids are mainly controlled by chemical drugs. Over the years, the control effect is getting worse and worse, and the resistance of psyllids is getting stronger and stronger. The frequency of application is increasing, and the dosage is increasing;

[0008] 3 There are growers who do not cooperate in digging up diseased trees, and there are many loopholes in the actual operation, and there are legal obstacles tha
