油茶炭疽病(Colletotrichum camelliaeMasse.)危害油茶花蕾、叶、果、新梢、枝干等部位。据我们在茶陵县二仙林场多年观察,果实感病后常使油茶减产10-20%,严重时竟达48.3%。对油茶炭疽病采取综合防治措施虽能取得良好效果,但因我国油茶分布范围广、面积大、地形复杂,应用现有的防治措施会遇到许多困难。从长远观点看,立足于抗病品种选育,才是解决这一问题的有效途径。为此,我们从1975年开始进行了这项工作的研究。
Camellia anthracnose (Colletotrichum camelliaeMasse.) Endanger Camellia buds, leaves, fruit, shoots, branches and other parts. According to our observation in Erling Forest Farm in Chaling County for many years, we often reduce the yield of Camellia oleifera by 10-20% after being infected with the fruit and up to 48.3% in severe cases. Although the comprehensive control measures against anthracnose of Camellia oleifera can achieve good results, due to the wide distribution, large area and complex topography of Camellia oleifera, there are many difficulties in applying the existing control measures. From a long-term point of view, based on breeding of disease-resistant varieties, it is an effective way to solve this problem. For this reason, we started the research of this work from 1975.
