Nicosulfuron is primarily used as a post-emergent herbicide for weed control in various crops. Here are some of the common applications of nicosulfuron:

1. Corn: Nicosulfuron is widely used in corn (maize) crops to control broadleaf weeds and grasses. It is effective against several common weeds such as common lambsquarters, pigweed, velvetleaf, foxtail, crabgrass, and barnyard grass, among others. It helps to improve weed control and promote healthy corn growth.

2. Sorghum: Nicosulfuron is also used in sorghum crops to control various grass and broadleaf weeds. It provides control over species such as foxtail, crabgrass, witchgrass, bermudagrass, and morning glory, among others. Proper application timing is crucial to ensure effective weed control while minimizing any potential crop injury.

3. Sugarcane: Nicosulfuron is employed in sugarcane cultivation to control grass weeds and select broadleaf weeds. It helps to manage weeds such as nutgrass, barnyard grass, goosegrass, bermudagrass, and broadleaf signalgrass. Care should be taken to prevent drift or direct application to sugarcane foliage, as it may cause injury to the crop.

4. Other Crops: While corn, sorghum, and sugarcane are the primary crops where nicosulfuron is widely used, it may also be approved for use in other crops depending on local regulations and label instructions. These may include crops like rice, barley, wheat, and some vegetable crops, where nicosulfuron can control specific weeds while minimizing crop damage when used according to label directions.
