Problems solved by technology

However, this pretreatment cannot ensure that the drug is evenly treated on the seed potatoes, and the drug effect can only be maintained for a period of time
In addition, during the growth period, the disease is not controlled because the primary infection of the spores of the exotic bacteria still exists
Delayed sowing is obviously affected by the climate. When the climate changes, the desired effect may not be achieved, and the control effect is unstable.
These two treatments are basically relatively simple to prevent or control potato late blight from a certain link. If the operation is wrong, it will be difficult to recover the damage caused by late blight

Abstract

The present invention discloses a potato late bright prevention and control agent set, which comprises a liquid a for potato seeds, a liquid b for seedlings and a liquid c used from a tuber formation period to a harvest period, wherein the raw materials of the liquid a comprise a gastrodia elata root extraction solution, MgCl2, NaH2PO4, myeena osmundieola lange spores, a black malt extraction solution and deionized water, the raw materials of the liquid b comprise KH2PO4, fumaric acid, MgSO4, vitamin B1, ethanol, acetyl salicylic acid and deionized water, and the raw materials of the liquid c comprise metalaxyl mancozeb, cymoxanil mancozeb, ethanol and deionized water. According to the invention, based on different stages in the potato growth process, the combinations of the three agents such as the liquid a, the liquid b and the liquid c are respectively adopted, the biological prevention and control is adopted as the main manner, and the chemical agent prevention and control is the auxiliary manner so as to effectively reduce the incidence rate of the potato late blight; and the raw materials are easily available, the cost is low, and the agent set and the method are particularly and easily promoted in vast rural areas in the country.

Description

technical field [0001] The invention relates to the field of potato pathogen prevention and control, in particular to a medicament group for preventing and treating potato late blight and a method for preventing and treating potato late blight. Background technique [0002] Potato late blight (Potato Late Bright) is caused by Phytophthora infestans, a devastating fungal disease that causes potato stem and leaf death and tuber rot. The pathogen overwinters mainly as mycelium in potato cubes. Sowing fungus-infected potato pieces will result in no germination or death after germination. Some become central diseased plants after unearthed. The spread expands. The sporangia on the diseased leaves can also infiltrate into the soil with rainwater or irrigation water to infect the tubers, forming diseased tubers and becoming the main source of infection in the following year. [0003] In recent years, potato late blight ranks first in the world's crop diseases in terms of losses ...
