抄録

The capillary watering system raising nursery in pot mechanically inhibited the dispersal of the conidia and successfuly depressed the spread of strawberry anthracnose. It was demonstrated that the conidia of Glomerella cingulate (=Colletotrichum gloeosporioides) were effectually dispersed in the water droplets and the wind. The conidia were hardly blown off by the wind in the absence of water. When the conidia on the diseased leaves were contacted with the water, they were immediately suspended into the water droplets which was splashed and blown by the wind.
