通过产地调查和药剂防治试验表明，橡胶树炭疽病的病原菌是一种弱寄生菌，从寄主幼嫩组织的自然孔口、伤口或皮孔侵入，引起发病。病菌产孢、侵染、扩展最适温度为１８～２４℃。此病在大量嫩叶时盛发流行，受寒害、半寒害的树梢是病原菌潜伏过冬和病原增殖的主要场所，降雨和高湿是发病和流行的主要条件，风雨是病害传播的主要媒体。在橡胶树抽芽５０％以上，抽叶率２０％～３０％时，在低温阴雨来临前３～５ｄ施用烟剂Ⅰ号和Ⅱ号，药量为７．５～１０ｋｇ／ｈｍ２，防治效果可达７８．２％～９４．１％。
Through the investigation of origin and prevention and cure of pesticides, it shows that the pathogen of rubber tree anthracnose is a kind of weak parasitic bacteria, which invaded from the natural orifice, wound or lenticel of the young tissue of the host, causing the disease. Bacteria sporulation, infection, expansion of the optimum temperature of 18 ~ 24 ℃. The disease flourished in a large number of young leaves popular, cold damage, semi-chilling trembling pathogens are latent winter and pathogen proliferation of the main sites, rainfall and high humidity is the incidence and prevalence of the main conditions, the storm is the main media for disease transmission. In the rubber tree sprouting more than 50%, leaf pumping rate of 20% to 30%, before the onset of low temperature rain 3 to 5d the application of smoke agents Ⅰ and Ⅱ, the dose of 7.5 ~ 10kg / hm2, control effect of up to 78 .2% ~ 94.1%.
