摘要
1993～1998年对辽宁省本溪县连山关林场和鞍山大孤山苗圃的落叶松幼苗立枯病及其防治进行了研究 ,结果表明:其致病菌是立枯丝核菌(RhizoctoniasolaniKuehn)、尖孢镰刀菌(Fusarium qxysporumSchl.)其德巴利腐霉(PythiumdebaryanumHesse)。采用多菌灵、甲基托布津、乙磷铝3种内吸杀菌剂 ,进行土壤消毒和苗期药剂喷雾试验 ,防治效果达81.6%～90.3 % 。
The preventing and treating techniques against larch seedling blight were studied at Lianshanguan forestry farm of Benxi county and Dagushan nursery of Anshan City in Liaoning Province from 1993 to 1998. It was found that the pathogenic germs were Rhizoctonia solani Kuehn, Fusarium oxysporum Schl. and Pythium debarryanum Hesse. By the combination of sterilizing soil and spraying seedling with systemic fungicides Carbendazim, thiophanate methyl and phosethyl-Al,the protecting effecliveners was obvious, reaching 81.6%～90.3%.
