CGA 71818, a novel fungicide for the control of grape and pome fruit diseases. Eberle, J.; Ruess, W.; Urech, P. A. (Agro Div., CIBA-GEIGY Ltd., Basel 4002, Switz.). Int. Congr. Plant Prot., Proc. Conf., 10th, Volume 1, 376-83. Br. Crop Prot. Counc.: Croydon, UK. (English) 1983. CODEN: 52UAA9. DOCUMENT TYPE: Conference CA Section: 5 (Agrochemical Bioregulators) CGA 71818 (I) [66246-88-6] is a new fungicide with protective and curative properties. At low concns. (2.5 g/100 L), I is active in vitro and in vivo against plant pathogenic ascomycetes, basidiomycetes and fungi imperfecti. I was evaluated in the field during several seasons, primarily on grapes and pome fruits. Its activity against powdery mildew pathogens is particularly striking. I controls primary and secondary infections of apple powdery mildew (Podosphaera leucotricha) and powdery mildew of grapes (Uncinula necator). I also provides good control of black rot (Guignardia bidwellii) of grapes, scab (Venturia) on pome fruits and a range of secondary pome fruit diseases.
