| 中文摘要: |
| 柑橘黄斑落叶病(Pestalotiopsis microspora)在广西柑橘上发生日趋严重,导致春梢和秋梢叶片大量落叶,严重影响树势和产量。通过菌丝生长速率法、孢子萌发法及田间药效试验评价了几种药剂对该病的防效,结果表明：乙蒜素、咪鲜胺、代森锰锌、苯醚甲环唑、吡唑醚菌酯等几种供试药剂均能完全抑制菌丝生长；咪鲜胺、嘧菌酯、苯醚甲环唑、乙蒜素、吡唑醚菌酯等几种供试药剂均能完全抑制孢子萌发；吡唑醚菌酯、吡唑醚菌酯+领美、吡唑醚菌酯.代森联、苯醚甲环唑的田间防效基本在95%以上,克菌丹防效为86%,硫磺的防效为79%。 |
| 英文摘要: |
| Yellow leaf spot disease on citrus was very serious in Guangxi province in recent years. It seriously causes spring-shoot and autumn-shoot falling leaves, It also seriously influences tree potential and yield. Using growth rate method of mycelium 、spore germination method and field efficacy test evaluate several fungicides efficacy, the results show：Ethylicin、Prochloraz、Mancozeb、Diphenoxazole、Pyraclostrobin can absolutely confine mycelium growth; Prochloraz 、Azoxystrobin 、Diphenoxazole 、Ethylicin 、Pyraclostrobin can absolutely confine spore germination.Pyraclostrobin、Pyraclostrobin+Lingmei、Pyraclostrobin.Thioneb、Difenoconazole control above 95% in yield. Captan has 86%, Sulfur has79%. |
