Guideline Tools: Weed Management in Sweet Corn, 2015
Darcy Telenko, Extension Vegetable Specialist
Cornell Vegetable Program

Herbicide effectiveness depends on many things. If the weed species you are trying to control has a poor or fair rating with a particular product, you should try other options. To be most effective, herbicides must be applied at the correct state of crop development and weed size. Effectiveness may also vary with method of application, rate, use of an adjuvant, size of weed, and soil and climatic factors.
