Abstract
The field experiment was conducted in the farm attached to the Agricultural College, Vellayani frr a period of two seasons to evaluate the performance of three granular weedicides on the lethality of weeds of rice and on the growth and yield of rice. There was no effect on the growth and yield of rice or on number and dry weight of weeds. The differences between unweeded control and continuously hand weeded treatment also remained nonsignificant both in terms of rice yield and weed growth. This points to the fact that continuous water logging itself was effective in keeping down weed growth and in preventing the consequent effect on rice yield. There was no apparent toxicity of the chemicals on the existing weed species of the area.
