An evaluation of some fungicides in the management of fruit and leaf spot (Phaeoramularia Angolensis) of citrus

Abstract

Four fungicide treatments viz Ben late (Benomyl), Cupravit (Copper oxychloride), Dithane M45 (Mancozeb), and
Ben late alternated with Dithane M45 were applied to control P!laeoramularia angolensi~ In a block of the variety
"Valencia" in the citrus orchard at Kiige, Uganda. No fungicide was applied to the control. Benlate, Cupravit and
Benlate alternated with Dithane M45 kept the disease level to about 50% compared to the 90% disease in the control.
Dithane M45 alone performed poorly with disease level of up to 80''/n. Therefore, the useofsuitablcfungicide can be
effectively integrated in the overall disease control strategy.
