Technical Field

The invention relates to the technical field of pesticides, in particular to a banana mosaic heart rot and banana streak prevention and control agent and a preparation method thereof.

Background

The banana mosaic heart rot is one of important virus diseases of bananas, and the pathogen of the banana mosaic heart rot is a strain of Cucumber Mosaic Virus (CMV). CMV is Cucumovirus (Cucumovirus) of the family brommosaic virus (bromovridae), whose genome is single-stranded positive sense RNA (+ ssRNA). It has been shown that CMV infects over 1000 plants, including monocots and dicots, and is also one of the important devastating pathogens for many crops and ornamentals. The leaves of the CMV-infected banana plants are in a yellow and green stripe, and are in a typical mottled flower-leaf shape, and particularly 1-2 leaves near the top are most obvious. The adult canna grows weakly and can not bear fruit, and even if the adult canna fruits are fruited, the adult canna fruits are difficult to grow into normal canna fruits. The close spread of the diseases in the banana orchard mainly depends on the medium of the cotton aphids, the corn aphids, the green peach aphids and the like, and the long-distance spread depends on the regulation and transportation of the disease-carrying suckers. The heart rot disease rate of the banana leaves is more than 90 percent under natural conditions, and the heart rot disease is not inferior to the banana bunchy top disease in harmfulness.

Banana streak is also one of the important viral diseases of bananas, and the pathogen is Banana Streak Virus (BSV). BSV belongs to the genus of baculovirus (Badnavirus) of Cauliiodoviridae (Caulimoviridae), and the genome of BSV is circular double-stranded DNA with the size of 7.5-8.0 kb. BSV infection of bananas can cause a variety of symptoms, typically intermittent and/or continuous chlorosis and spindle marks on the leaves, which gradually become necrotic black streaks as the symptoms progress. BSV infection can also cause many other symptoms, such as leaf shrinkage, curling, necrosis into heart rot, and the like. The symptoms of banana streak disease and banana mosaic heart rot are very similar and are easy to be confused in the field. Studies have shown that BSV can both integrate into the banana host genome and cause infection under appropriate conditions, producing viral particles. Therefore, the potential hazard of BSV viruses to cause sigatoka is not negligible.

However, in the prior art, the single control technology is adopted to control the banana mosaic heart rot and the banana streak disease, and a large amount of manpower and material resources are needed to distinguish and control in the process, so that the input cost is high. At present, the common control technology of the banana mosaic heart rot and the banana streak disease is rarely researched at home and abroad, so that how to research and design a banana mosaic heart rot and banana streak disease control medicament and a preparation method thereof are the problems which are urgently needed to be solved at present.
