赤枯病，在我国华东地区常有发。1-4年生实生苗和幼树受害最重，随树龄增长而逐渐减轻。病害初发生在苗木下部针叶和小枝上，先产生褐色小斑点，渐扩大成深褐色，使针叶和小枝枯死。以后继续蔓延到上部枝叶，还可从小枝扩展到主茎上，形成深褐色溃疡状病斑，如病斑包围主茎一周，则其上部枝叶呈赤褐色而枯死。发病严重的苗圃地，有全部苗木被毁的危险。
这种状况有利于二者在植物病害生物防治中协同作用的发挥，表明了两种微生物在松赤枯病生物防治中联合作用的可能性。
This was beneficial to cooperative role of the mentioned two antagonists in plant disease control, and also showed that two antagonists had combination possibility in biocontrol of pine blight.
从防治效果的绝对值来看，“预先接种病原菌”方式在实际生产中表现为病害已发生再进行生防菌处理，这种情况对松赤枯病的控制无实际意义。
From the absolute value of control effect, "Priority of the pathogen inoculation" means the disease has happened in the practice, the case is not meaning for controlling the pine needle blight.
