Which of the following is true about herbicide effectiveness?

Herbicide effectiveness can indeed be significantly influenced by temperature. Higher temperatures can enhance the absorption and activity of many herbicides, allowing them to work more effectively, while cooler temperatures may slow down their action or even lead to reduced efficacy. Certain herbicide formulations are designed to perform optimally within specific temperature ranges, and deviations from these ranges can hinder effective control of target weeds.

Wind, application techniques like shotgun application, and the timing of application all play critical roles in herbicide performance and are factors that practitioners must carefully consider to ensure successful weed management. However, acknowledging that temperature is a key factor highlights the complexity and interaction of environmental variables in successful herbicide applications.
