摘　　要：松树抽梢期,于树冠喷洒0.2％硼酸水溶液,防止芽坏死效果明显。抽梢初期,用烟雾机喷6.5％百菌清油雾,有较好的防梢枯效果。使用此法防治松梢枯病,在当前经济水平下,易为林业单位所接受。上述两法结合起来,配成硼和百菌清乳油,用烟雾机喷油雾防治松梢枯病,效果更好,有推广应用前途。Spraying an 0.2% aqueous solution of boric acid upon the crown of pines during developing shoots in order to prevent necrosis of buds achieved good results. Employing a smoking sprayer in spraying 6.5% chlorothalonil during the initial stage of developing shoots also achieved fairly good results. If a combined operation with both chemical compounds mentioned above to make a mixed emulsion are in progress, the result will become even more effective. Under the economic standard today,the above-mentioned control measures for die-back of pines are readily accepted by forest productive units and open up prospects for popularization and application.
