What are the pesticide fungicides and antiseptic preservatives commonly used in bananas?
(1) Isobacteria
Isobacteria is a broad-spectrum contact pesticide fungicide. It has good bactericidal effect on various fungi. It is used in a variety of crops to control a variety of diseases, and is also often used as a storage and preservation treatment of fruits and vegetables. 50% of different bacteria urea wettable powder 500 times liquid soaking fruit for 1 to 2 minutes, has a good effect on banana crown rot during storage and transportation.
(2) propiconazole
Propiconazole is a systemic fungicide that acts as both a protective and a therapeutic agent. It can be absorbed by roots, stems, and leaves, and can be quickly transmitted upwards in plants. It is mainly used for the prevention and treatment of a variety of human diseases, and is used for the prevention and treatment of banana scab and leaf spot disease. It is commonly used with 25% enemy de-emulsion oil 1000-1500 times liquid mist, and the interval is 21~28 days.
(3) chlorothalonil
Chlorothalonil is a broad-spectrum pesticide fungicide. It has a good preventive effect on a variety of crop fungal diseases, but has no systemic conduction. When the crop has been invaded by the bacteria and enters the body, there is no therapeutic ability. For the prevention of banana scab and various leaf spot diseases, 75% chlorothalonil WP can be sprayed 800~1000 times, and the protection period is 7~10 days.
(4) Prochloraz
Prochloraz is a broad-spectrum fungicide of imidazoles, has no systemic action, but has osmotic conduction. Applicable to fruit preservation after harvest, the effect of preventing anthrax is obvious. Commonly used 25% prochloraz aqueous emulsion 1000 ~ 2000 times liquid soaked fruit.
(5) Inhibition
Inhibition is a broad-spectrum pesticide fungicide, which is often used to control the storage of fruits and vegetables, especially for fungal diseases that have developed resistance to Tecdo and carbendazim. 50% imazalil emulsion 500 times liquid immersion fruit for 1 to 2 minutes, control banana aphid disease during storage and transportation has a good effect.
(6) Proline phosphorus
Also known as keke phosphorus, Yishoubao, is a nematicide and insecticide, with a contact killing effect, prevention and treatment of a variety of pathogenic nematodes, has a good control effect on a variety of underground pests. It can be applied before crop planting, before planting or during growth. Each plant is covered with 20% of 20% Yibao granules around the banana head (with a stem-centered, 0.75-meter radius) and can cover a variety of banana nematodes.
(7) gram phosphorus
Also known as benzene line phosphorus, Limanchu, is a nematicide and insecticide , with contact and systemic action, the agent is absorbed by the roots and transported to the top, so insects such as aphids and thrips can be sucked. Kill. The agent can control a variety of nematodes of various crops, and the dosage of controlling the banana nematodes is 30% of the 10% force full granules per plant, and the residual effect period is up to 3 months. In addition to the reference to the phosphorus, the application method can be immersed in water because of its excellent water solubility.
(8) Potassium permanganate
Potassium permanganate is not only a commonly used disinfectant, but also used as an ethylene absorbent in the preservation of fruits and vegetables to absorb the ethylene released from fruits and vegetables, which can significantly delay the maturity of the product and prolong the storage and preservation period. Generally, diatomaceous earth, vermiculite or foam bricks which are fully adsorbed with potassium permanganate saturated solution are placed in a small bag which is ventilated, and then placed in a carton or a film bag loaded with bananas for storage and storage, and the preservation effect is obvious. It can be used together with antiseptic fungicides for better results.
(9) High fat film water emulsion
A white, non-toxic, milky substance made from high-grade fatty alcohols or higher fatty acids. After spraying or soaking the crops on water, it will form a thin layer of invisible high on the surface of the plant. The lipid film wraps the plant to regulate the physiological activities of the plant, block the invasion of the pathogen, and limit the expansion of the pathogen, and achieve the purpose of drought resistance, cold prevention, disease prevention, preservation and preservation. It has been widely used in fruit trees, vegetables, Chinese herbal medicines, crop production and storage and preservation. Spraying crops, generally 150-200 kg per kilogram of water, the field retention period is about 15 days and can be mixed with various fungicides; fruits and vegetables are preserved and preserved, generally 150-200 kg per kilogram of water, soaked for 1 minute, other chemicals, Please refer to the relevant part of mango.
