Biointensive Weed Management in Aerobic Dry Sown Rice– A Review

Effective and efficient weed management practices in time and space are crucial in increasing aerobic rice productivity. There have been increasingly strong economic, social and biological pressures to limit the use of herbicide nowadays. There exists possibility of exploring alternative weed management systems that have the potential to reduce herbicides use on a wide scale through mechanical and cultural methods of weed control. Most of the past researches put forth emphasis on the effectiveness of herbicides in relation to the dominant weed species and soil conditions at the time of application and the combination of herbicides and manual weed control. Whereas in this review, the current researches that pursue the refinement of cultural and biological control technologies for use in integrated weed management systems are discussed.
