【 摘 要 】

The new cultivation method of spring wheat sowing before continuous snow cover has many advantages, such as increase of yield and avoidance of scab, but has the flaw of uncertainty of overwintering. Since our previous paper showed that the decrease of overwintering of spring wheat sown before continuous snow cover was caused by snow mold diseases, we examined the effect on overwintering of some fungicides against snow mold sprayed on soil surface after sowing or coated on seeds in this report. Spraying of the fungicide (fluazinam) showed a variable effect. On the other hand, coating seeds with the fungicide clearly improved the overwintering ability. Though the most effective amount of coating was 2.5% of seed weight, we could decrease the effective amount of the fungicide by mixing with calcium peroxide including gypsum. We concluded that coating seeds with the fungicide improves the overwintering ability of spring wheat sown before continuous snow cover.
