1999年夏季对北京部分草坪的主要病害种类调查结果表明 :在夏季 ,北京的主要草坪病害是褐斑病和腐霉枯萎病 ,其病原物分别是丝核菌属和腐霉菌属的真菌。其中 ,草地早熟禾、多年生黑麦草及翦股颖在夏季的病害主要由丝核菌引起 ,而高羊茅病害则主要由腐霉菌引起。室内药剂筛选结果表明 :在相同浓度下 ,百菌清对丝核菌的抑制作用最强 ,而甲霜灵对腐霉菌的抑制作用最强。单一药剂代森铵及百菌清、多菌灵、三唑酮与敌克松、甲霜灵的复配药剂对这两种真菌均具有很强的抑制作用。
The investigation on the major diseases of some lawns in Beijing in the summer of 1999 showed that in summer, the main lawn diseases in Beijing were brown spot and Pythium blight. The pathogens were the fungi of Rhizoctonia and Pythium, respectively. Among them, the disease of meadow bluegrass, perennial ryegrass and populus euphratica in summer was mainly caused by Rhizoctonia solani, while the tall fescue was mainly caused by Pythium. The results of indoor pharmacy screening showed that chlorothalonil had the strongest inhibitory effect at the same concentration, while metalaxyl had the strongest inhibitory effect on Pythium. A single agent, ammonium and chlorothalonil, carbendazim, triadimefon and the enemy grams of pine, metalaxyl compound agent for both fungi have a strong inhibitory effect.
