Product information
Kelvin Top SC, 5 litres is a nicosulfuron herbicide with powerful effects against weeds through foliar action and minimal residual activity. It is very flexible in application and provides systemic action against annual and perennial grass weeds, as well as against dicotyledonous weeds, to a lesser extent.
Benefits:
- Systemic herbicide for foliar application;
- Controls a wide range of weeds found in corn crops;
- Ideal for post-emergent applications;
- Fast absorption and fast-acting.
Action mode:
Kelvin Top SC controls invading weeds in corn:
- Blocks the enzyme acetolactate synthase (ALS) biosynthesis, required for the synthesis of essential amino acids, and weed growth stops shortly after application, within only 6 hours;
- The herbicidal activity acts in the growth points of plants, that become chlorotic in a few days, then necrotic, and their death occurs one or three weeks after application, depending on the species and environmental conditions;
- Corn is tolerant of nicosulfuron because it is rapidly metabolized to a form that does not affect it.
Methods of application:
Applications are made during post-emergence when corn plants have 4-6 leaves, annual grass weeds are in the 1-3 leaves stage, up until twinning, perennial grasses are 10-15 cm in height, and dicotyledonous weeds are small, in the 2 leaf stage.
Apply in a dose of 1 to 1.4 l per ha.
Crop | Weeds attacked | Application moment | Dose |
Corn | Johnson grass | Postemergence | 1-1.4 l/ha |
Compatibility:
Compatible with most of the crop products available on the market.
Before mixing with other crop protection products, perform a small-scale compatibility test.

Recommendations:
The best results are obtained when Kelvin Top is applied to actively growing weeds.
