Abstract
Fusarium (mainly F. moniliforme [Gibberella fujikuroi]), Curvularia (mainly C. lunata [Cochliobolus lunatus]) and Alternaria sp. were the most commonly isolated fungi from Capitan sorghum seeds produced under humid tropical conditions in Mayaguez. Seedborne incidence of G. fujikuroi and C. lunatus was negatively correlated with seed germination and positively with seed damage. Seedborne incidence of A. sp. was not associated with either. Weekly applications of benomyl + captan (0.5 + 0.5 kg/ha) from the boot stage to physiologic maturity completely controlled G. fujikuroi and reduced C. lunatus. Fungicide application also increased seed yield, 100-seed wt. and germination.ADDITIONAL ABSTRACT:Weekly applications of 0.5 kg benomyl + 0.5 kg captan/ha from the boot stage to physiological maturity of sorghum in Puerto Rico in 1980 controlled Fusarium moniliforme and Curvularia lanata and increased seed yields from 13.8 to 18.0 g/plant and 100-seed wt. from 2.6 to 3.8 g. Germination was also increased
