Application

Mode of Action:

• Nicosulfuron is branched chain amino acid synthesis inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth.

• Nicosulfuron is a selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation in xylem and phloem to the meristematic tissues.

• Nicosulfuron is absorbed by the leaves of treated plants and translocated to the meristematic tissue causing growth inhibition, discoloration, and plant death.

• Nicosulfuron is most effective against grasses when applied between emergence and tillering.

• Broadleaf weeds are most effectively controlled when treated at the 2-3-leaf stage.

• Split applications can improve the efficacy of the product.

• Nicosulfuron has no residual activity, being quickly metabolised by plants.

Usage of Nicosulfuron:

• Nicosulfuron is rainfast within six hours, the use of adjuvants such as non-ionic surfactants or crop oil concentrates to enhance the activity of its granular product.

• Nicosulfuron is selective post-emergence control in maize of annual grass weeds, including Setaria, Echinochloa, Digitaria, Panicum, Lolium and Avena spp., broad-leaved weeds, including Amaranthus spp. and Cruciferae, and perennials such as Sorghum halepense and Agropyron repens.

• Nicosulfuron shows high selectivity to maize, but treatment of maize crops with some soil insecticides sensitises the crop to nicosulfuron, resulting in crop damage.

• Applied at 35-70 g/ha.
