摘  要:
对竹柏炭疽病进行了田间观察和调查,其病原菌初步鉴定为胶胞炭疽菌。该病害危害幼苗和成年植株,以幼苗受害较重,株发病率100%,严重时大量落叶直至全株仅剩枝干。该病害4月中旬开始发生,4月底至5月中旬为发病高峰。室内药效测定结果表明,50%多菌灵可湿性粉剂、75%百菌清可湿性粉剂和10%苯醚甲环唑水分散粒剂对病原菌均有明显的抑制作用,效果最好的是多菌灵。

摘  要:
The anthracnose of Podocarpus nagi,the pathogen of which is Colletotrichum gleosporioides,infected the seedlings and the adult trees of P.nagi.The seedlings were infected more seriously than the adult trees,with an infection rate of 100%.In serious cases,the leaves fell massively and only the trunks remained.The disease began in the middle of April,and the peak came from the last ten days of April to the middle of May.The efficacy tests showed that carbendazim,chlorothalonil(Dakening),difenoconazole and chlorothalonil(Keneng)significantly inhibited the growth of the pathomycete,but the action of carbendazim was the strongest.
