Weed Control

National herbicide screening programme for lowland rice

Four new post emergence herbicides were evaluated to assess their weed controlling ability. Among the tested herbicides pyanchlor (pyribenzoxion 500 ml/ha) could be identified as broad spectrum herbicide while SETOFF (Cinosalfuron 100g/ha) and AIM (Curfentrazone 62.5 g/ha) could be identified for controlling broad leaves and sedges in wet seeded rice under dry zone conditions. Maha 2000/2001 results also showed that similar performances. These conditions confirmed the results.

Evaluation of different weed control methods for large scale, low cost maize production

Two wheel tractor mounted rotervator, non-selective herbicides, and manual weeding were compared to select suitable low cost weed control method for large-scale maize production. Experimental data clearly revealed that the weeding method had no effect on grain yield. The highest cost for weeding incurred in mamoty weeding followed by herbicides and for rotervator weeding.

Evaluations of weed controlling ability of flufenacet on maize

FLUFENACET - new herbicide was compared with ALACHLOR and it did not show any toxic effect on emerging maize seedlings FLUFENACET appears to be promising alternating herbicide to ALACHLOR for weed control in maize cultivation.
