A field trail was conducted to study the effect of spray application of various copper and other fungicides on three rice varieties in relation to their phytotoxicity and effect on yield. The fungicides were tested at the normal recommended dosage and also slightly enhanced dosages to see the phytotoxicity. No phytotoxicity was caused by copper and fungicides and fungicide mixtures on any of the rice varieties tested yield in different fungicide treatments also did not differ significantly.
