摘要
甜菜生育期褐斑病罹病率达5%～10%时,喷洒1次含三苯基醋酸锡20%的禾本卡克15kg/hm^2兑水600kg/hm^2,比对照(喷洒清水)提高块根产量25.0%,提高含糖率1.5度,增加产糖量39.8%;经济效益显著,投入产出比达1∶28。
When the disease occurring rate of sugarbeet cercospora leafspot was 5%～10%, 20% triphenyl-tin-acetate(15kg mixed with 600kg water per ha) was sprayed in the sugarbeet field, the control result indicate that the root yield, sugar content and sugar yield were respectively increased by 25.0%, 1.5°S and 39.8% in comparison with the non-treatment, furthermore, there was a significant benefit was visible and input-output ratio was 1∶28.
