The purpose of the resent study is to
evaluate the effectiveness of fungicides and the spray regimes on the Cocoyam
taro leaf blight control in Nsukka, Southeastern Nigeria. Cocoyam taro
(Colocasia esculenta L) is a large crop of edible aroid tuber, but blight of
cocoyam leaf The greatest constraints to
the development of cocoyam in Phytophthora colocasiae have been caused by Since 2009, Nigeria. In order to assess the
effect of fungicides and spray, field trials were carried out. Leaf growth regimens, occurrence of disease;
severity of disease; and cocoyam tuber yield. The lawsuits They were carried out at the Crop Science
Research Farm Department , University of Nigeria, Nsukka for Two seasons for planting. Two-fungicide
treatments (Ridomil Gold Plus, Ridomil+Champ Dp50 percent: Mixture and monitor of 50 percent) and five
spray regimes (No spray, weekly spray, 2nd weekly spray, 3rd weekly spray) Weekly spray and 4th weekly spray regimes)
were set out in a randomised full 3 x 5 factorial regimen With three
replications, block architecture (RCBD). Results showed that there were
substantial fungicide therapies (P < 0.05) variance in leaf / stand number,
occurrence of disease, severity of disease and tuber Yields / hectare in both
seasons of cultivation. There were no substantial differences (P < 0.05) On
all calculated parameters in both, between Ridomil and Ridomil+Champ (50
percent:50 percent) mixture) Seasons for crops. ANOVA showed substantial
variation in disease occurrence (P < 0.05) among the Ridomil treated plots
had the highest fungicides at all trial times in early season planting at 90
DAP, Incidence of disease compared to other choices for fungicides, with the
lowest incidence of disease rated By the parcels handled by the power. Taro
leaf was substantially reduced by the fungicides and spray regimes Enhanced
growth and yields, blight. In weekly spray regimens conducted, Ridomil treated
cocoyam plots Best compared to other fungicides and the treatment choices for
the spray regime. Besides the adoption of Via integrated disease management
(IDM) in Nsukka, Southeastern Nigeria, high yielding resistant cultivar(s),
weekly foliar spraying of Ridomil or Ridomil+Champ should be incorporated into
taro leaf blight control.
