TECHNOLOGY OF ANTHRACNOSE CONTROL ON INCREASING STRAWBERRY PLANTLETS

Strawberry anthracnose is caused by several species of fungi and C. gloeosporioides is the major fungus in Zhejiang province of China.
It is difficult to raise strawberry plantlets at the main rain season.
In this paper we describe a useful technology to raise strawberry plantlets in high temperature and humidity environments. (1) Use of disease-free planting material.
Disinfectants like Cabrio and Mancozeb also can be used to sterilize the mother plants. (2) Soil disinfection and sterilization.
Solar soil disinfection technology is a cost-effective method.
Soil disinfectants such as chlorine dioxide and trichloroisocyanuric acid can also be used in the course of solarization. (3) Rain-shelter and shading cultivation.
This measure can keep the plantlets free of rain.
The most suitable sunshade net provides 80% shade.
Under this cultivation, anthracnose disease incidence was reduced to 6.2% while the control was 61.7%. (4) Use of fungicide combinations.
The intensified fungicides reduced the disease incidence to 8.7%, significantly lower than those of a single fungicide treatment.
It’s better to use plant growth retardants in order to grow fine plantlets by early July.
Plantlet quality was increased significantly compared with the control.
