油茶炭疽病是油茶的主要病害,在严重发病区因病落果可达20％以上,因此该病的防治是油茶丰产措施的重要一环。病菌主要在病树上的枝、蕾(芽)、叶、果的病部越冬。次春病组织中菌丝向健部蔓延,孢子随雨露及雨夹风传播,先侵害春梢,继而多次侵染新果及叶、蕾(芽)等。夏秋时还侵染不定芽萌发梢,导致落果、落蕾、枝条溃疡和枯死。秋后可以从果皮蔓延侵染近熟种子,并可侵染花器。伤口有利于病菌侵入。每年7—9月初是果实炭疽病的发病盛期,也是
Camellia anthracnose is the main disease of Camellia oleifera in the serious disease area up to 20% or more, so the disease prevention and control is an important part of the oil-yielding measures. Pathogens mainly in the tree branches, buds (buds), leaves, fruit of the disease overwinter. Secondary spring disease mycelium to the Department of Health spread spores with rain and rain wind spread, the first invasion of spring shoots, and then repeatedly infested new fruit and leaves, buds (buds) and so on. Summer and autumn also affect adventitious buds sprouting shoots, leading to falling fruit, falling buds, branches of ulcers and dead. Autumn after the infection can spread from the peel near-ripening seeds, and can invade flowers. Wound conducive to bacteria invade. The beginning of July-September each year is the peak of fruit anthrax disease, too
