Herbicides for pocket friendly weed control in rice

Abstract

Herbicides can provide effective and economical control of weeds in rice field. It saves labour cost up to 40% and reduces drudgery. It also plays important role in facilitating the adoption of direct-sown rice (DSR) technology, but over reliance on one type of herbicide or faulty way of application can lead to herbicide resistance development in weeds and adversely affect environment and human health. Herbicides, if not properly applied, may also cause problems of phyto-toxicity. Therefore, correct use of herbicide is essential to ensure that chemical residues on crops do not exceed the limits. Recommended doses of herbicides do not generally injure people, livestock, or crops if used properly following recommended precautions.
