大樱桃的流胶病及防治试验
Deciduous Fruits(2000)
Abstract
研究明确了大樱桃流胶病分真菌性流胶病和细菌性流胶病。前者又分枝干干腐型和溃疡型。枝干干腐型流胶病致病菌为Botryosphaoria ribis Grossenb et Duggar;溃疡型流胶病致病菌为Bortyosphaeria dothidea Ces.st de Not.。细菌性流胶病的致病菌种类尚不清楚。防治方法以刮除病斑后再用生石灰10份+石硫合剂1份+食盐2份+花生油0.3份+适量水涂抹效果最好,防效达100%,但病斑大刮皮后不易愈合。不刮病斑,用生石灰10份+石硫合剂1份+食盐2份+花生油0.3份+适量水涂抹的防治效果次之,为93.8%。
