| Abstract:
Studies on weed control in no tilled pineapple cultivation were conducted in Rayong Field Crops Research Centre and Petchaburi Horticultural Research Station. Herbicides were applied as post emergence at 60 days after soil preparation and 30 days before planting pineapple suckers. The results found that bromacil, glyphosate, glyphosate+diuron and paraquat+dimethazone at the rate of 3.0, 1.5, 1.0+2.0 and 0.75+1.125 kg ai/ha, respectively provided good weed control without phytotoxicity to the crop. Imazapyr at the rate of 0.15 kg ai/ha applied at 60 days before planting showed excellent weed control for at least 5 months but it caused severely effect on growth and yield of pineapple. However, tilled cultivation before planting showed better control efficacy than no tilled cultivation in which yield was differed by 14.3%. | |
