杏树流胶病的发生与防治研究

【目的】轮台杏树(Prunus)流胶病发生严重,2011年在轮台县采用不同的方法和药剂进行防治试验,旨在选择最佳的杏树流胶病防治方法和药剂。【方法】采用刮治、涂治、主干涂白和喷施硼肥四种方案,以及四种药剂来防治杏树流胶病,对比不同方案及药剂的效果。【结果】四种方案中刮治防治流胶病效果甚微,涂治防治的效果较好,主干涂白和喷施硼肥可以减轻杏树流胶病的发生。在发病盛期四种药剂中农丰灵的防治效果最好,为57.4%石硫合剂次之,为34.4%。【结论】杏树流胶病的最佳防治方法为春季树体萌动之前和流胶病盛发期使用农丰灵进行涂治防治,并配合主干涂白和喷施硼肥。

Control Test of Apricot Gummosis

【Objective】Gummosis is the most severe disease to apricot trees(Prumus).Different medicament and different methods for prevention of gummosis in Luntai County,Xinjiang were tried during the year 2011.The objective of this study was to find the best method for controlling apricot gummosis.【Method】Four methods like scraped colloids,smeared medicament,smeared lime and sprayed boron to prevent apricot gummosis were applied.After that,the four choices were compared and contrasted in order to find the best one and the best effect.【Result】Smeared medicament is better than scraped colloids to the prevention of apricot gummosis.Smeared lime and sprayed boron both can reduce the gummosis.Nongfengling(a pesticide's brand) is the best medicament for preventing apricot gummosis,and lime sulfur followed.【Conclusion】So the best method to prevent apricot gummosis is smeared nongfengling before the tree growing in Spring and the arriving peak of gummosis.At the same time smeared lime and sprayed boron can increase the control effect.
