Method for preventing and treating diseases in seedling stage of peanuts

Abstract

The invention relates to the technical field of agricultural planting, in particular to a method for preventing and treating diseases in the seedling stage of peanuts, which is characterized in that 10-20 g of 40% polyketone wettable powder is mixed with seeds per mu. A lower low limit is used in a disease-free or light disease area, and an upper limit is used in a continuous cropping field and aserious disease area. The method can effectively prevent and control diseases in the seedling stage, can well inhibit overgrowth, achieves the effects of disease prevention, seedling strengthening andseedling hardening, reduces the drug use cost, controls the diseased plant rate to be 0.5-0.8% through experimental verification to be equivalent to that of control defensive treatment and bright shield treatment, but has better seedling compaction and seedling strengthening effects.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for preventing and controlling peanut seedling disease. Background technique [0002] There are many diseases in the seedling stage of peanuts, especially in heavy cropping fields. Generally, the dead seedling rate is about 2%, and in severe fields, it is more than 10%. At the same time, due to the demand for high yield, the amount of base fertilizer is generally sufficient. If there is sufficient water, it is easy to cause Seedlings grow wildly, leaving hidden dangers for high and stable peanut yields. For this reason, Shilashi, Weifu, Liangdun and other antibacterial seed coating agents are commonly used in production to prevent diseases, and squatting seedlings are realized by clearing trees. The labor required is 1.0-1.5 per mu, and the cost is relatively high. Contents of the invention [0003] In order to solve the above problems, the invention pro...

Problems solved by technology

[0002] There are many diseases in the seedling stage of peanuts, especially in heavy cropping fields. Generally, the dead seedling rate is about 2%, and in severe fields, it is more than 10%. At the same time, due to the demand for high yield, the amount of base fertilizer is generally sufficient. If there is sufficient water, it is easy to cause Seedlings grow wildly, leaving hidden dangers for high and stable peanut yields

For this reason, in production, antibacterial seed coating agents such as Shilashi, Weifu, and Liangdun are commonly used to dress seeds to prevent diseases, and squatting seedlings are realized by clearing trees. The amount of labor per mu is 1.0-1.5, and the cost is relatively high.
