Problems solved by technology

Banana Panama disease is a fungal disease, and it is easy to occur in acidic sand texture. The pathogenic bacteria are Fusarium oxysporum and its variants. It survives as chlamydospores, and its survival period can last for several years. It has the characteristics of rapid onset and severe disease. Among the existing ones, there is no specific drug to eradicate the disease. It is mainly based on prevention and treatment. The prevention and control methods are as follows: The diseased plants are filled with herbicides in a pressure sprayer barrel and injected with the medicine. One week later, the leaves of the diseased plants dry up rapidly. After two months, the leaves and pseudostems are completely dry, and they can be burned by fire. Some tuber tissues left in the diseased spots have not yet rotted. , can also be dug out and chopped, and burned together with the pseudostem. When developing new land and establishing banana garden rotation, the banana garden with a disease incidence of more than 10% should be rotated with rice or sugar cane for more than two years before planting bananas.
This kind of prevention and control method has high work intensity, very poor effect, incomplete removal, pathogens will attack at any time, and cannot play an effective role in prevention and treatment.

Embodiment 1

[0013] Each component was weighed according to the following parts by weight: 6 parts of beffendex, 60 parts of calcium oxide, 1 part of carbendazim, and 3 parts of thiophanate-methyl. Mix evenly to obtain the composition for preventing and treating banana Panama disease.

[0014] The use method of the composition of preventing and treating banana Panama disease, 1 part of said composition is mixed with 100 parts of water to be formulated into aqueous solution, selects the banana field that planted banana for many years and frequent Panama disease, plant 100 banana plants, from banana plant leaflet stage From the beginning, the aqueous solution that will be configured is poured on the roots of banana plants, and each banana plant is sprayed with 0.5 kg. The interval between two adjacent sprays is 15 days, until the buds are broken, and there are 10 banana plants with disease.

Embodiment 2

[0016] Each component was weighed according to the following parts by weight: 10 parts of beffendex, 75 parts of calcium oxide, 3 parts of carbendazim, and 5 parts of thiophanate-methyl. Mix evenly to obtain the composition for preventing and treating banana Panama disease.

[0017] The use method of the composition of preventing and treating banana Panama disease, 3 parts of said composition is mixed with 150 parts of water to be formulated into aqueous solution, select the banana field that planted banana for many years and frequent Panama disease, plant 100 banana plants, from banana plant leaflet stage From the beginning, the aqueous solution that will be configured is poured on the roots of banana plants, and each banana plant is sprayed with 0.7 kg. The interval between two adjacent sprays is 20 days, until the buds are broken, and there are 8 banana plants with disease.

Embodiment 3

[0019] Each component was weighed according to the following parts by weight: 15 parts of beffendex, 70 parts of calcium oxide, 5 parts of carbendazim, and 8 parts of thiophanate-methyl. Mix evenly to obtain the composition for preventing and treating banana Panama disease.

[0020] The use method of the composition of preventing and treating banana Panama disease, 5 parts of said composition is mixed with 200 parts of water to be formulated into aqueous solution, select the banana field that planted banana for many years and frequent Panama disease, plant 100 banana plants, from banana plant leaflet stage From the beginning, the aqueous solution that will be configured is poured on the roots of banana plants, and each banana plant is sprayed with 1 kg. The interval between two adjacent sprays is 30 days, until the buds are broken, and there are 12 banana plants with disease.

Abstract

The invention discloses a composition for preventing and treating the panama disease of bananas. The composition comprises the following components in part by weight: 6 to 15 parts of beifende, 60 to 70 parts of calcium oxide, 1 to 5 parts of carbendazim and 3 to 8 parts of thiophanate methyl. The using method of the composition comprises the following steps: adding 100 to 200 parts of water into 1 to 5 parts of composition to prepare an aqueous solution; and spraying the prepared aqueous solution at the roots of banana plants from the leaflet stage of the banana plant to the bud breaking period, wherein 0.5 to 1 kilogram of the aqueous solution is sprayed on each banana plant, and the interval time of adjacent spraying is 15 to 30 days. The prepared composition can increase the pH value of soil and inhibit pathogenic bacteria, has interference effect on the fission process of the panama pathogens of the bananas, fulfils the aim of effectively preventing and treating the panama disease of the bananas, and is sprayed on the banana trees easily on a large scale.

Description

technical field [0001] The invention relates to the field of disease and insect control of crops, in particular to a composition for preventing and treating banana Panama disease and an application method thereof. Background technique [0002] Banana Panama disease is also known as banana yellow leaf disease. The lower old leaves of the affected banana plant turn yellow first, gradually expanding to the middle rib, the petiole softens, bends and droops, and finally withers, and the upper young leaves also gradually turn yellow, eventually causing the entire banana plant Withered and died, sometimes the leaf sheath around the pseudostem of the diseased plant splits longitudinally from the base. Banana Panama disease is a fungal disease, and it is easy to occur in acidic sand texture. The pathogenic bacteria are Fusarium oxysporum and its variants. It survives as chlamydospores, and its survival period can last for several years. It has the characteristics of rapid onset and ...
