摘要
为探明樟树溃疡病菌侵入樟树的途径，找出有效防治办法，进行了樟树溃疡病病菌入侵途径及药剂防治试验．结果表明，樟树溃疡病菌主要从伤口侵入樟树，并以针伤的发病率和死亡率最高，达９０％～１００％．７０％甲基托布津、４０％多菌灵可抑制菌丝生长．７０％代森锰锌２０００倍液和波尔多液可抑制孢子萌发，且效果好．伤口涂抹７０％甲基托布津１０００倍液，防治效果最佳，４０％多菌灵１０００倍液次之．
Experiments are conducted to study the ways that camphor tree canker bacterium infect camphortrees. This is also aimed at working out a method to prevent the spread of the disease and cure the disease. The result shows that most of the pathogenic bacterium enter camphortrees throuth camphortree′s wounds. The sick rate and death rate caused by needle rank the highest,which is between 90% and 100%. 70% Thiophanate Methyl and 40% Carbendazol have significant effect on checking the growth of hypha as well as 70% Mancozeb and Bordeaux mixture which is highly capable of checking the germination of a spore. To treat cuts or wounds with 70% Thiophanate Methyl (×1000) is the most effective way. While 40% Carbendazol (×1 000) ranks the second.
