摘要
:1995～ 1996年利用沤肥浸渍液对苹果斑点落叶病进行先期预防 ,取得了较好的效果 ,与清水对照相比 ,所用沤肥浸渍液的防效均在 80 %以上 ,且效果优于同期处理的多菌灵、高美施。采用悬滴法对苹果斑点落叶病孢子在各类沤肥浸渍液中的萌发率进行测定 ,与清水对照相比 ,各浸渍液对孢子萌发的抑制率均在 70 %以上 ,最高达 84 .5%。
Field trials were conducted to confirm the efficacy of various livestock manure compost extracts to apple alternaria leaf spot ( Alternaria mali Roberts) in 1995～1996. The relative efficiencies of 4 compost extracts made from horse, cow, pig, and sheep manure were >80% compared with control and higher than that of Carbendazim and Komix. Using hanging drop method, the effects of compost extracts on conidia germination of A. Mali were tested. The inhibiting rates were all >70%. The highest reached 84.5%.
