An agricultural weed wiper is a device used for the targeted application of herbicides to weeds in fields, pastures, and other agricultural settings, minimizing the impact on surrounding desirable plants. It works by wiping a herbicide-soaked wick or pad directly onto the weed, effectively delivering the chemical only to the targeted plants. This selective approach reduces herbicide usage, minimizes drift, and is particularly useful in areas where spray drift could be problematic, like near waterways or sensitive crops.
