Effect of repeated annual application of preemergence herbicides on paddy field weed populations


, : Effect of repeated annual application of preemergence herbicides on paddy field weed populations. Proceedings of 5th Asian Pacific Weed Science Society Conference, Tokyo, Japan, 1975: 287-292

Repeated annual application of butachlor at 1.5 kg, thiobencarb + simetryne 2.55 kg, nitrofen 2.1 kg and 2,4-D-isopropyl 0.9 kg/ha 4-6 days after transplanting rice on loam soil to control annual weeds, increased weed dry wt. creating a predominance of the perennial sedges Eleocharis kuroguwai and Cyperus serotinus and the annual sedge Scirpus juncoides; these species increased from 45% of the total weed population after the first year's treatment to 69% after the fourth year.
