CGA 169374 SCORE is a new systemic broad-spectrum triazole fungicide with excellent protective and curative properties against a wide range of diseases caused by plant pathogenic Ascomycetes Basidiomycetes and Deuteromycetes. Extensive field trials have shown that CGA 169374 is highly active in different environments with great potential to manage important diseases in tropical and subtropical regions. Foliar sprays gave effective control of Oncobasidium theobromae on cocoa; Oidium mangiferae and Colletotrichum sp. in mangoes; Elsinoe spp. and Mycosphaerella citri in citrus; Cercospora sp.

Erysiphe sp. Alternaria sp. and Colletotrichum sp. in beans; Cercospora sp. and Colletotrichum spp. on chili; Erysiphe sp. Sphaerotheca sp. and Mycosphaerella melonis in cucurbits. The excellent activity of CGA 169374 against leaf spot diseases rusts and powdery mildews was not increased by mixtures with contact fungicides. The control of anthracnose however was enhanced by mixtures with e.g. mancozeb or chlorothalonil which resulted in increased fruit set and improved yield and quality. CGA 169374 was generally well tolerated by all target crops under a range of different geographical and climatical conditions. Due to the broad-spectrum and the long-lasting protective and strong curative activity CGA 169374 will significantly contribute to an improved disease management in many important tropical crops.

Abstract

CGA 169374 SCORE is a new systemic broad-spectrum triazole fungicide with excellent protective and curative properties against a wide range of diseases caused by plant pathogenic Ascomycetes Basidiomycetes and Deuteromycetes. Extensive field trials have shown that CGA 169374 is highly active in different environments with great potential to manage important diseases in tropical and subtropical regions. Foliar sprays gave effective control of Oncobasidium theobromae on cocoa; Oidium mangiferae and Colletotrichum sp. in mangoes; Elsinoe spp. and Mycosphaerella citri in citrus; Cercospora sp. Cercosporidium sp. Sphaceloma sp. Phoma sp. and Puccinia sp. in peanuts; Alternaria spp. in potato onions and tomato; Septoria lycopersici in tomato; Cercospora sp. Uromyces sp. Isariopsis sp. Erysiphe sp. Alternaria sp. and Colletotrichum sp. in beans; Cercospora sp. and Colletotrichum spp. on chili; Erysiphe sp. Sphaerotheca sp. and Mycosphaerella melonis in cucurbits. The excellent activity of CGA 169374 against leaf spot diseases rusts and powdery mildews was not increased by mixtures with contact fungicides. The control of anthracnose however was enhanced by mixtures with e.g. mancozeb or chlorothalonil which resulted in increased fruit set and improved yield and quality. CGA 169374 was generally well tolerated by all target crops under a range of different geographical and climatical conditions. Due to the broad-spectrum and the long-lasting protective and strong curative activity CGA 169374 will significantly contribute to an improved disease management in many important tropical crops.
