Prevention method for strawberry anthracnose

Abstract

The invention relates to a prevention method for strawberry anthracnose. According to the prevention method for the strawberry anthracnose, drug prevention and physical cure are conducted simultaneously at the seedling stage. The drug prevention is: drug is sprayed every 13-15 days from the first day of the seedling planting to two months, every 7-8 days from the second month to the fourth month and till the planting or transplant rejuvenation period; and after the planting or transplant rejuvenation period, the drug is sprayed every 13-15 days till the bud appearing period, then the drug prevention is stopped. The physical cure is: pruning old and sick leaves at the position of 1-2cm away from the strawberry root; pruning the creeping stem from the root; and drug treatment is conducted before the planting of the strawberry. After three years of experience and practices and the popularization and application in Dandong areas, the prevention method for the strawberry anthracnose can greatly improve the survival rate after the planting of strawberries, creates considerable economic benefits for strawberry growers, and promotes the development of the local strawberry industry to a certain extent.

Description

technical field [0001] The invention relates to a method for preventing and treating strawberry anthracnose. Background technique [0002] Strawberry production is a new industry that has emerged in recent years. With the continuous improvement of people's living standards, the demand for strawberries is increasing day by day. In strawberry production, anthracnose is one of the important diseases that affect the survival rate of strawberry seedlings and the later yield. In particular, the main cultivars "Hongyan" and "Zhangji" in the local solar greenhouse started to develop disease from the seedling stage, and the disease spread quickly. The preventive effect of pesticides is good, but the treatment effect is poor, which leads to extremely low emergence rate of these two varieties, lower yield and quality, and even no yield or harvest when the disease is severe, which seriously affects the development of the local greenhouse strawberry industry.
