Embodiment 1

[0034] A compound biopesticide for preventing and treating Fusarium wilt of banana-Panama disease is composed of the percentages of the following mass fractions:

[0035] Oligosaccharides 30%

[0036] Chitosan 45%

[0037] Lysozyme 25%

[0038] When the banana disease occurs, use the medicament of the present invention in a prescribed dose to spray the diseased banana tree with injection for three times in a known normal temperature and time.

[0039] Irrigation method:

[0040] Medication time and frequency: Spray the medicine for the first time when the diseased plants are first planted after banana planting, once every 60 days at other times, and once every 40 days during the rainy season.

[0041] How to use: When spraying the medicine, first use a small shovel to gently dig out the soil of the banana head to expose the bulb of the banana head, and then pour the prepared liquid around the tree to the banana head and nearby bulbs, young roots and soil In the middle, t...

Abstract

The invention relates to a compound biological pesticide for preventing and treating a banana wilt-panama disease. According to the occurrence characteristic of the banana wilt-panama disease, two biological inductive agents are selected by agent screening, and the two biological inductive agents and biological lysozyme are subjected to combination compound, so that a formula has a function of inducing a banana to generate disease resistance and has a bactericidal effect, and a purpose of preventing and treating the banana wilt-panama disease is achieved; the compound biological pesticide is nontoxic, harmless and pollution-free; a use method is simple; the compound biological pesticide is injected at a well-known room temperature and time and root irrigation is performed for three to five times; the cost is lower; and implementation is easy.

Description

technical field [0001] The invention relates to a compound biological pesticide, in particular to a compound biological agent for preventing and treating banana wilt-Panama disease, and belongs to the technical field of biological pesticide production. Background technique [0002] Banana Fusarium wilt is a soil-borne vascular disease caused by Fusarium oxysporum f. sp. Cubense (FOC), which is caused by the infection of Fusarium in the soil by bananas. The pathogen invades from the banana roots, colonizes and clogs the vascular bundles, leading to wilting and yellowing of the leaves. Fusarium can be transmitted through soil, water, and tools, and is highly contagious. The fungus causes the banana tree to turn reddish-brown from the woody vessels at the root, extending into the bulb, and then turn black-brown and dry up and die. [0003] This disease pathogenic bacteria spreads fast, is difficult to radical cure, has a strong impact on the development of banana industry of ...
