Abstract
Background: Purple nutsedge is a weed that has a tough profuse underground tuber system, and is predominantly a perennial species in many crops. Objective: To evaluate the influence of different water regimes to the effectiveness of herbicides used for controlling the purple nutsedge. Methods: Experiment was arranged in a Randomized complete block design (RCBD) with a two-factor factorial design and three replications. The net-house tests were conducted with six treatments and two different water regimes of “watered daily” and [...]

Purple nutsedge is one of the most competitive sedge species in many cropping systems of tropical agriculture
The purpose of this study was to evaluate the efficacy of florpyrauxifen-benzyl versus commercial standards on purple nutsedge under different water regimes
3.1 Herbicide treatment and water regime affect the viable shoots of purple nutsedge
Summary
Purple nutsedge is one of the most competitive sedge species in many cropping systems of tropical agriculture. Controlling purple nutsedge is a difficult and costly treatment because the herbicides kill only the above ground parts and leave the underground tubers undamaged. Different methods have been studied to control purple nutsedge, including chemical herbicide and non-chemical options. Mulching with black polyethylene is an effective solution for controlling purple nutsedge (Webster, 2005). Allelopathy could be considered as another method for controlling the purple nutsedge. Crop-weed competition may suppress the purple nutsedge population in rice production. Purple nutsedge is a weed that has a tough profuse underground tuber system, and is predominantly a perennial species in many crops. Objective: To evaluate the influence of different water regimes to the effectiveness of herbicides used for controlling the purple nutsedge. The tested herbicides were florpyrauxifen-benzyl, halosulfuron-methyl, 2,4-D and glyphosate
