ABSTRACT
The field experiment was conducted during the kharif season 2013-14 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to investigate the “Phytotoxicity ratings and weed control ratings as influenced by weed control treatments in greengram (Vigna radiata L.)”. The experiment was laid out in Randomized Complete Block Design with three replications and ten treatments. The crop toxicity rating observed at 7, 14 and 21days after pre emergence herbicides application revealed that none of the herbicide dose had any injury on the crop growth and the crop was grown normally. The application of post-emergence herbicides treatments T4, T6 and T8 showed the phytotoxicity effect on the crop at seven and 14 days after spray. The rest of the treatments recorded no phytotoxicity injury on the crop. However, the crop recovered completely after 21 days after spray. All the pre-emergence herbicide application treatments T1, T2, T5, T6, T7 and T8 recorded good to excellent control of weeds at 7 days after spray and good control at 14 days after spray. At 21 days after spray, T1 and T6 treatments were recorded good control of weeds, while the treatments T2, T5, T7, T8 and farmers practice observed satisfactory control of weeds.
Key words: Greengram, Herbicide, Sequential application, Weed.
