摘要

Phytophthora blight, caused by Phytophthora capsici, is a destructive disease of peppers and cucurbits in Illinois and worldwide. Fungicide use is a significant component of management strategies of Phytophthora blight of peppers. Studies were conducted in the laboratory and field to evaluate efficacy of selected fungicides for management of Phytophthora blight of peppers in Illinois. In the laboratory, sensitivity of five P. capsici isolates from Illinois was evaluated to the fungicides cyazofamid,dimethomorph, mandipropamid, and oxathiapiprolin. Development of colonies and production of sporangia of the isolates were assessed at concentrations of 0.0, 0.1, 0.5,1.0, 5.0, and 10.0 ug mL1 of cyazofamid; 0.0, 0.1, 0.5,1.0, 2.5, and 5.0 ug mL 1 of dimethomorph; 0.0, 0.05, 0.1, 0.5,1.0, and 5.0 ug mL 1 of mandipropamid; and 0, 1, 10, 50, 100, and 200 ug mL1 of oxathiapiprolin in V8 juice agar in Petri plates. Mycelial growth and sporangia production were significantly (P=0.05) reduced by all four fungicides tested in the laboratory. The ECso values of the fungicides for mycelial growth ranged from 0.34 to 3.63 ug mL1 (average 1.03 ug mL1); from 0.75 to 4.66 ug mL1 (average 2.98 ug mL1); from 0.13 to 7.18 ug mL1 (average 4.03 ug mL1); and from 0.03 to0.97 ug mL 1 (average 0.28 ug mL1) for cyazofamid, dimethomorph, mandipropamid, and oxathiapiprolin, respectively. The EC-,o value for sporangia production was 10, 2.5, 0.05, and 100 ug mL1 for cyazofamid, dimethomorph, mandipropamid, and oxathiapiprolin, respectively. In 2016, effectiveness of fungicides cyazofamid (Ranman 400SC), mandipropamid (Revus 2.09SC), cymoxanil + famoxadone (Tanos 50WDG), and oxathiapiprolin (Orondis Opti-A) for management of P. capsici in bell pepper in the field wasinvestigated. Percent asymptomatic plants in the plots drenched with Ranman 400SC or Orondis Opti-A at transplanting were significantly higher than those of the plots either were sprayed with Ranman 400SC + copper (Kocide-3000 41.6Df) or drip-delivered Orondis Opti-A at transplanting.

Capsici的管理。用Ranman 400sc或Orondis Opti-A浸没在移植处浸没的图中无症状植物的百分比显着高于用Ranman 400sc +铜（Kocide-3000 41.6df）喷涂或在移植时滴注的Orondis Opti-A的曲线。
