摘要
研究表明，火炬松干枯型枯梢病始于６月，在７～９月的高温干旱期，病害较严重，但整个病变过程比较缓慢。１９９３～１９９６年防治试验说明，５～６月，土壤或叶面施硼砂、微肥复合晶、钼酸铵、柑桔微肥，防治效果好。尤其是硼砂，防效高，肥效稳定。土壤施硼砂２３～２５ｇ／株，１ａ一次；叶面喷０．２％的硼砂水溶液，连喷３次，可以在生产上推广应用。
The incidence of dried up die back of loblolly pine begins in June,it becomes more serious during the dry season from July to September,but the whole process of pathological changes is slow.Three year experiments have showed that it will achieve good effects to apply sodium borate,compound fertilizer of minor element,ammonium molybdate and citrus minor element fertilizer to the roots or crown of the pines in May or June.The controlling effect of sodium borate,which is applied to the roots 23～25 g/plant yearly or to the crown with its 0.2% water solution,is especially good and stable.This can be popularied and applied in the production.
