鱼雷草组织在施用量为 0.28、0.56、1.12、2.24 和 4.48 kg/ha 时暴露于草甘膦的比例影响了通过再生长测量的控制。随着施用量的降低，组织暴露的影响更加明显。这项研究表明，在水位较高时，需要使用较高剂量的草甘膦，此时鱼雷草组织暴露于除草剂喷雾的情况较少，而在水位较低期间，可以使用较低剂量的草甘膦。在草甘膦喷雾混合物中添加水调节剂 Quest (R) (0.25% v/v) 可减少草甘膦施用后模拟降雨事件的影响。其他十二种助剂不影响模拟降雨事件的效果。
The proportion of torpedograss tissue exposed to glyphosate at application rates of 0.28, 0.56, 1.12, 2.24, and 4.48 kg/ha affected control as measured by regrowth. The effect of tissue exposure was more pronounced as application rate decreased. This study suggests that higher rates of glyphosate need to be used during higher water levels, when less torpedograss tissue is exposed to herbicide spray and lower rates may be used during periods of low water levels. Addition of the water conditioning agent Quest (R) (0.25% v/v) to glyphosate spray mixtures diminished the influence of simulated rain events following glyphosate application. Twelve other adjuvants did not influence the effect of simulated rain events.
