Abstract

The invention relates to a medicament for preventing and treating liberobacter asiaticum and a preparation method thereof. The medicament for preventing and treating liberobacter asiaticum comprises the raw material components by the mass percentage: 20%-30% of a bactericidal component, 2.0%-5.0% of a penetrant, 0.2%-0.5% of a preservative, and the balance water. The preparation method comprises the steps: mixing and stirring the bactericidal component and water, then adding the penetrant and the preservative, mixing evenly, then filtering, and filling to obtain the medicament for preventing and treating liberobacter asiaticum. The medicament for preventing and treating liberobacter asiaticum can make the drugs more effectively penetrate through a citrus bark system and be transported to aphloem tissue of citrus, kills gram-negative bacteria, achieves the purpose of preventing and treating liberobacter asiaticum, thereby solving the problems of short drug effect time and poor effect of conventional biological pesticides.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a medicament for preventing and treating citrus huanglongbing and a preparation method thereof. Background technique [0002] Citrus huanglongbing, also known as yellow shoot disease, yellow wilt and green fruit disease, is a disease that seriously threatens the growth of citrus plants. In 1919, citrus huanglongbing was first discovered in South China. In the past century, citrus huanglongbing has spread to more than 50 countries including five continents including Asia and Africa, causing great harm to citrus production. Citrus huanglongbing has spread in large numbers in citrus growing areas in southern my country, and has had a devastating impact on the local citrus industry. The survey shows that in Guangxi alone, the annual direct economic loss caused by citrus Huanglongbing disaster is close to 1 billion yuan, and the expected economic loss is even greate...
