Abstract:
Various fungal diseases
reduce groundnut yield but Cercospora leaf
spot commonly called, Tikka disease is most
detrimental one. A field experiment was
conducted to evaluate the efficacy of
different fungicides and their doses on
Cercospora leaf spot of groundnut. Five
different fungicides (Chlorothalonil,
Propineb, Mancozeb, Nativo and Triazole)
having three different doses (prescribed,
half & prescribed+half) were used to control
Cercospora leaf spot of groundnut.
Groundnut variety (YH-14) highly
susceptible to Cercospora leaf spot was
used. The experiment was laid down in
RCBD design. The data were analyzed
statistically by Fisher’s analysis of variance
technique. Results showed that maximum
disease control with high pod yield was
observed with Nativo and Triazole
treatments. Efficacy of Chlorothalonil was
also better than Mancozeb and Propineb.
Maximum disease control and pod yield was
observed when Nativo was used @ 0.97g/L
of water, followed by @ 0.65g/L and 0.32
g/L, respectively. Propineb was the least
effective in controlling Cercospora leaf spot
of groundnut as well as having minimum
pod yield.
