摘要： 为给番荔枝叶斑病的科学用药提供依据，开展防治番荔枝叶斑病化学药剂的筛选工作。通过田间药效试验，对300 g/L苯醚甲环唑·丙环唑悬浮剂、275 g/L氟唑菌酰羟胺·丙环唑悬乳剂等7种复配药剂进行评估，明确其对番荔枝叶斑病的防治效果以及对番荔枝产量的影响。结果显示，在供试药剂中，17%唑醚·氟环唑微乳剂170 mg/kg、19%啶氧·丙环唑微乳剂126.7 mg/kg、42.4%唑醚·氟酰胺悬浮剂226.1 mg/kg、275 g/L氟唑菌酰羟胺·丙环唑悬乳剂275 mg/kg这4个处理的防治效果最为突出。末次药后14 d，其防治效果介于83.20%~86.08%之间。田间测产结果表明，这4个处理的番荔枝产量相较于清水处理提高了16%以上。综上所述，氟唑菌酰羟胺·丙环唑等4种药剂对番荔枝叶斑病的防治效果显著，在实际生产中推荐使用这些药剂来防控番荔枝叶斑病。

Abstract:

In order to screen out chemical fungicides to control cherimoya leaf spot, an evaluation of compound fungicides was conducted through field trials in the study. Seven compound fungicides widely used in agricultural production in China, which were 300 g/L difenoconazole·propiconazole suspension concentrate (SC), 275 g/L pydiflumetofen·propiconazole suspo-emulsion (SE), 325 g/L difenoconazole·azoxystrobin SC, 400 g/L mefentrifluconazole·pyraclostrobine SC, 42.4% pyraclostrobine· fluxapyroxad SC, 19% picoxystrobin·propiconazole micro-emulsion (ME) and 17% pyraclostrobine·epoxiconazole ME, were used in the test to confirm the control effects under field conditions. The survey result showed that 17% pyraclostrobine·epoxiconazole ME 170 mg/kg, 19% picoxystrobin·propiconazole ME 126.7 mg/kg, 42.4% pyraclostrobine·fluxapyroxad SC 226.1 mg/kg, 275 g/L pydiflumetofen·propiconazole SE 275 mg/kg had control effects of 83.20%-86.08% after third application, significantly higher than other treatments, as well as the yield increase percentages were higher than 16%. The four aforementioned fungicides were safety and had positive control effects and effectively reduce production losses caused by cherimoya leaf spot, thus it is recommended for consideration of use in production.
