2、田間調(diào)查，結(jié)果顯示，常發(fā)生的病害有葉斑病、花/果/莖腐病、枝枯病等，病害類(lèi)型有39種。分離鑒定的結(jié)果表明，真菌性病害32種，細(xì)菌性病害1種，根結(jié)線(xiàn)蟲(chóng)引起的病害1種，病毒類(lèi)病害3種，植原體病害1種，寄生性藻類(lèi)病害1種。初步查明海南省主要熱帶牧草病害的種類(lèi)和為害狀況，其中柱花草為害最為嚴(yán)重的病害為炭疽病（ColletotrichumgloeosporioidesPenZ.），王草則以瘟病[Pyriculariagrisea（Cke.）Sacc]發(fā)生最為嚴(yán)重，其他牧草以葉斑病為害居多，為害水平中等至輕微。關(guān)鍵
