abstract: The effect of temperature on the latent periods of rust, late leaf spot and early leaf spot diseases of
groundnut caused by Puccinia arachidis, Phaeoisariopsis personata and Cercospora arachidicola.
respectively, was studied. The latent periods (LP) of rust, late leaf spot and early leaf spot ranged from
12-49 days, 13-38 days and 13-39 days, respectively, between 12 C and 33 C An equation relating the
rate of pathogen development (1/LP) to temperature was fitted using daily mean temperatures to provide
three cardinal temperatures: the minimum (7"m,n), optimum (r^pc), and maximum (Tm,,). T^,^ was about
I2°C for rust and about 10°C for the two leaf-spot diseases. Top, for all three diseases was close to 25 C.
7"max was Bl'C for early leaf spot, and extrapolated values for late leaf spot and rust were about 35 and
40°C, respectively.
