Cu-AA (Amino Acid), Zn-AA and Mn-AA mixture for preventing downy mildew

Abstract

The invention discloses Cu-AA (Amino Acid), Zn-AA and Mn-AA mixture for preventing downy mildew, and belongs to the technical field of plant disease biological prevention and control. The Cu-AA, Zn-AA and Mn-AA mixture is prepared from the following components in parts by weight: 50 to 60 parts of hibiscus coccineus bean dreg fermentation liquor, 80 to 90 parts of rice husk fermentation liquor, 20 to 30 parts of brown sugar, 1 to 5 parts of copper hydroxide, 5 to 8 parts of zinc sulfate and 5 to 8 parts of manganese sulfate. According to the Cu-AA, Zn-AA and Mn-AA mixture disclosed by the invention, all components of a recipe of the Cu-AA, Zn-AA and Mn-AA mixture are plant raw materials and are fermented into components containing Cu-AA, Zn-AA and Mn-AA, so that the Cu-AA, Zn-AA and Mn-AA mixture is non-toxic and residual-free, the downy mildew of cucurbits caused by Pseudoperonospora cubensis can be effectively restrained, and even more, the quality of commodity fruits can be increased.

Description

technical field [0001] The invention relates to an amino acid copper-zinc-manganese mixture for preventing and controlling downy mildew, which belongs to the technical field of plant disease prevention and control, and mainly aims at preventing and controlling the downy mildew of Cucurbitaceae caused by Cuban pseudoperonospora, and provides a non-toxic and non-residual biological control agent. Background technique [0002] The pathogen of downy mildew on Cucurbitaceae plants caused by Cuban Pseudomonas downy mildew is an important disease in the production of melons such as cucumbers and melons. Downy mildew can continue to occur when melons are planted in greenhouses throughout the year. Once the disease occurs, it usually It can't be controlled, and the epidemic is extremely fast, causing the middle and lower leaves to dry up, and quickly develop upwards. If it is not controlled in time, it will cause devastating losses. The spread of the disease is very fast, also commo...

[0002] The pathogen of downy mildew on Cucurbitaceae plants caused by Cuban Pseudomonas downy mildew is an important disease in the production of melons such as cucumbers and melons. Downy mildew can continue to occur when melons are planted in greenhouses throughout the year. Once the disease occurs, it usually It can't be controlled, and the epidemic is extremely fast, causing the middle and lower leaves to dry up, and quickly develop upwards. If it is not controlled in time, it will cause devastating losses. The spread of the disease is very fast, also commonly known as "horse horse pole". Once the diseased plant is found, it only needs 3-4 times of expansion and re-infection to cause a catastrophe. Therefore, prevention is more important than treatment in the prevention and treatment of this disease. , the methods commonly used are divided into high-temperature stuffy shed, fumigation, and spraying methods for prevention and control. The chemical agents used include Shuanglingwei, metalaxyl-mancozeb, anti-virus alum, ethylphosphine-aluminum, swiss-mancozeb, etc. Systemic pesticides are used for prevention and control. In the current use of greenhouses, it is common to use a single agent that cannot effectively inhibit the occurrence of the disease. Frequent replacement is required for prevention and control. The dosage of pesticides is increasing, resulting in difficulty in prevention and control. , and these chemical pesticides will cause the loss of soil vitality, pesticide residues and many other sequelae. At present, the consumer market is paying more and more attention to the food safety issues of pesticide residues. The green and pollution-free planting mode is gradually gaining popularity. The attention of growers, how to use biological control methods, avoid the use of chemical pesticides, and control the downy mildew caused by Cuban pseudoperonospora, which is easy to be directly decomposed in the soil without pesticide residues, is the current method An important topic for plant protection technicians
