Comparative efficacy of - nine fungicides for control of coffee leaf rust in the 1981/82 period in Kenya :
Efficacy of nine fungicides, Calirus 50 WP, A6097A 25 EC, Peremnox 50 WP, Delan 75 WP, Copper Nordox 50 WP, Kocide 101 50 WP, Sicarol 15 OD, Duter Extra 47.5 WP and Bayleton 25 WP, was compared for the control of coffee leaf rust under field conditions. All the fungicides effectively controlled coffee leaf rust under high epidemics. Under high disease pressure, at Azania, Calirus 50 WP (0.3 & 0.2*), A6097A 25 EC (0.1), Delan 75 WP (0.3), Copper Nordox 50 WP (0.35) and Kocide 101 50 WP (0.35) sprayed plots gave yields as high as plots sprayed with Perenox 50 WP (0.7), which was used as a standard fungicide. The rest of the fungicides i.e Duter Extra 47.5 (0.27), A6097A 25 EC (0.2) and Sicarol 15 OD (0.4) gave much lower yields than Perenox 50 WP (0.7) sprayed plots. The implications of these results are discussed
