Abstract

The efficiency of trifluralin (a,a,a-trifluoro- 2,6-dinitro-N,Ndipropyl-p-toulidine), as influenced by rate (0, 0.25, 0.50, 1.0 and 2.0 kg/ha) and method of application (soil mixed, surface applied and simulated harrow) was studied using rice as test plant.

Trifluralin cause stunting, inhibition of root growth and reduction of fresh and dry weights of roots and shoots of rice seedlings. this inhibitory effect of trifluralin was noted in all rates and methods of application. However, greater retardation of growth was observed in higher rates and when application was done by either soil mixed or simulated harrow method.

Injury ratings taken at 14 and 35 days after sowing showed that the maximum damage occured at 2.0 kg/ha rate of application. Application at 1.0 kg/ha rate was as effective as 2.0 kg/ha in causing phytotoxicity when applied by simulated harrow method.
