Abstract
Rice (Oryza sativa), the staple food of more than half of the population of the world, is an important target to provide food security and livelihoods for millions. Direct seeding of rice (DSR) refers to the process of establishing the crop from seeds sown in the field rather than by transplanting seedling from the nursery. Therefore, field experiment was conducted on clay loam soils at Agricultural Research Station, Jangamaheswarapuram, Guntur Dist. Andhra Pradesh, India, during 2017-18 and 2018-19 in direct sown rice (DSR) to test the efficacy of Triafamone 18.52 SC herbicide on production and to evaluate the lasting impact of herbicides on succeeding blackgram. Among the herbicides tested only Triafamone 18.52 SC @ 100 g a.i. ha-1 had a slight phytotoxic effect on direct sown rice. Phytotoxicity of Triafamone 18.52 SC @ 100 g a.i. ha-1applied at 2-3 leaf stage of weed effect the rice crop, exhibiting slightly stunted growthand the leaves failed to fully expand and became yellow at 7 days after application. However, those symptoms disappeared, and the Rice plants recovered within a week. Further, it was observed that none of the herbicides applied at tested rates had adverse effect on succeeding blackgram. In among the herbicides Triafamone 18.52 SC @ 100 g a.i. ha-1(T5) and Triafamone18.52 SC @ 50 g a.i. ha-1(T4) applied at 2-3 leaf stage of weedwere at par recorded significantly higher grain yield over weedy check (T1).
