  1. Water primrose: Chemical control using herbicides

    A controlled, replicated, randomized study at the National Institute for Agricultural Research, Venezuela (Suárez et al. 2004) found that use of the herbicide halosulfuron-methyl (Sempra) resulted in a significant reduction in water primrose Ludwigia spp. coverage without apparent toxicity to rice plants.  Treatment of 60 g active ingredient/ha produced the highest percentage control, with average reduction in water primrose coverage of 80%.  The trial was conducted in a randomized block design with five treatments and four repetitions. Treatments were undertaken in experimental plots marked with fixed 0.25m2 metal frames. Sempra, formulated as water dispersible granules at a concentration of 75% halosulfuron-methyl by weight, was applied to rice crops 26 days after sowing at the following range of doses 0, 15, 30, 45 and 60 g active ingredient/ha.   The herbicide was applied with a manual sprayer.  Weed coverage and rice crop quality were then evaluated.
