甜菜根腐病的生物和化学控制初步研究

采用小区和大区对比相结合的试验方法，探讨了生物和化学药剂防治甜菜根腐病的效果。研究结果表明，５０％福美双可湿性粉剂与７０％土菌消可湿性粉剂等量混合后种子重量的０．８％拌种、荧光假单胞菌１００倍液浸种２４ｈ、５％菌毒清水剂３００倍液浸种２４ｈ与５０％福美双可湿性粉剂种子重量０．８％拌种（对照）比较，防治甜菜根腐病效果均达５０％以上，差异显著，并且具有兼防甜菜立枯病和明显的增产增糖作用

A Preliminary Study on the Biological and ChemicalControl of Sugarbeet Root Rot

Approaching on effect of the biological and chemical control of sugarbeet root rot with small plots and large plots tests. The test results have shown that 50% TMTD and Hymexazol mixed on seed at seed weight 0.8% which comparing with seed soak for 24h in the liquid 100 times of fluoro false single spore and seed soaking with liquid of 5% Junduqing 300 times for 24h. The effect of sugarbeet root rot could controlled to more than 50%, difference significantly and sugarbeet damping-off controlled also, sugar yield and sugar content increased significant.
