Problems solved by technology

However, due to various reasons, the effects of these control methods are limited, some related research is still in the preliminary stage, and the continuity of the effect has not been confirmed, so it is impossible to fundamentally solve the problem.
[0004] At present, there is no effective control method for citrus Huanglongbing

[0049] 1. Experimental materials and methods

[0050] 1.1. Experimental plant material

[0051] (1) Cultivate susceptible branches in the laboratory: In April 2016, we grafted Shatangju trees infected with Huanglongbing onto healthy 2-year-old Shatangju seedlings, and then kept them in the culture room for cultivation. After 10 months, the typical symptoms of Huanglongbing appeared on the leaves with blocked veins and spots.

[0052] (2) Field test field I: from orchards in Guangdong Province, China - about 10-year-old Shatang orange trees infected by Huanglongbing.

[0053] (3) Field test field II: about 10-year-old navel orange trees infected with Huanglongbing disease from an orchard in Ganzhou City, Jiangxi Province, China.

[0054] (4) In order to minimize the influence of uneven distribution of Huanglongbing bacteria, the sampling method is as follows:

[0055] In the experiment of soaking the isolated branches with copper ammonia, sampling method: collect one leaf at...

Abstract

The invention discloses a medicine and a method for preventing and treating citrus liberobacter asiaticum. The medicine comprises thiazoline and cuaminosulfate, and the method specifically comprises the steps that the thiazoline and the cuaminosulfate are sequentially applied, and the thiazoline and the cuaminosulfate are combined to be used for treating, preventing and controlling the citrus liberobacter asiaticum. Experimental results show that the scheme has a remarkable treatment effect on liberobacter asiaticum, and the treatment method can have very long persistence. Meanwhile, the prevention and control mechanism is also explored, and a new direction and thought are provided for research of the Huanglongbing mechanism and prevention and control means. The invention has important application value and prospect for the treatment and prevention and control of liberobacter asiaticum.

Description

technical field [0001] The invention belongs to the field of agricultural technology. In particular, it relates to a medicine and a method for preventing and treating citrus huanglongbing. Background technique [0002] Citrus Huanglongbing, also known as citrus greening disease, is a serious and devastating disease of citrus. Typical symptoms include yellow buds, mottled leaves, clogged leaf veins, early fruit ripening, shriveled and smaller fruits, branch wilting and tree death, reducing fruit yields and quality, while seriously damaging the growth of citrus trees. The annual average yield loss of huanglongbing trees is 30-100% of the total yield, and usually loses fruiting ability or dies within 2-5 years after being infected. If it is not controlled in time, its spread speed is very alarming. It is called "citrus cancer". ", affecting the citrus industry all over the world, and is the number one quarantine disease in the citrus industry at home and abroad. [0003] At ...
