Abstract: Three kinds of soil disinfectants and fungicides were used in the strawberry nursery and cultivation land, and its control effect on strawberry soilborne diseases, plantlet raise and strawberry production were tested. The results showed that the three soil disinfectants had significantly reduced the disease incidence of strawberry anthracnose and fusarium wilt both in nursery and cultivation land. Chloropicrin and dazomet had the better inhibitory effects. The number of plantlets and fruit production treated with chloropicrin increased 11.23% and 14.78%, respectively. The disease incidence of anthrax was also significantly reduced after application of six kinds of fungicides. The anthracnose incidence of control treatment was 89.3%, while the 75% tebuconazole·trifloxystrobin WG dilution with 3 000 times and 43% tebuconazole SC dilution with 5 000 times had the disease incidence of 4.0%. And the control efficiency was as high as 98.41% and 98.54%, respectively．
