- <p><span>Effective weed management is essential for ensuring the profitability of sugarcane cultivation, as weeds compete with the crop for vital resources such as moisture, nutrients, and sunlight throughout the growing season. Taller sugarcane plants have demonstrated a greater tolerance to glyphosate-based herbicides. A significant aspect of the present study was the strategic application of herbicides four months after planting, a stage at which sugarcane appears to exhibit increased resistance to herbicidal stress. </span><span>As presented in Table 2, the post-emergence application of herbicides resulted in varying degrees of weed suppression, measured in terms of dry weight. The treatment yielding the most effective control showed a reduction in weed biomass to 38.8 g/m², in contrast to the untreated control, which recorded a significantly higher weed biomass of 105 g/m². Specific herbicidal treatments, such as 2,4-D sodium salt and Metribuzin, resulted in weed dry weights of 65.9 g/m² and 61.2 g/m², respectively, while Paraquat was less effective, yielding 83.3 g/m². </span><span>Previous research indicates that early application of herbicides such as glyphosate—particularly within the first 90 days after planting—can negatively affect sugarcane yield. However, findings from the current study suggest that when applied at an appropriate growth stage, glyphosate demonstrates superior efficacy in controlling weed populations compared to other herbicidal treatments. </span><strong><span>Conclusion: </span></strong><span>The study concludes that glyphosate is a highly effective post-emergence herbicide for weed control in sugarcane cultivation. Its application, particularly after the initial growth phase, may provide efficient and selective weed management without adversely affecting crop performance.</span></p>
