Klass

Klass 80 WP controls broad spectrum of mono and dicotyledonous weeds before emergence. Most of those weeds are also controlled at an early (1 to 3 leaves) post emergence stage.

Mode of Action :

The active ingredient, Diuron is taken up by the roots of germinating weeds, and translocated into the young leaves, where it interacts with the Hill Reaction of photosynthesis. Chlorosis and finally necrosis follows within a few (3–8) days, depending on species, temperature, and soil conditions. To a certain degree, Diuron is taken up via the leaves, and penetrates directly to the site of action. This foliar activity takes place only with young, tender leaves, i.e., early post-emergence. The selectivity of Klass is based on the availability of the a.i. for the root system, i.e., it is purely physical and not physiological. Herbicide Resistance Action Committee (HRAC) Classification Group C2

Advantages :

  • Broad-spectrum residual control.
  • Pre and early post emergence action on grassy and broad leaf weeds.

Recommendations for Use:

How To Use

  • Apply on moist, clean soil. Newly emerged weeds at the 1 to 3 leaf stage can be controlled as well.
  • Apply with a knapsack or tractor mounted sprayer, fitted with flat fan or flood jet nozzles.
  • The soil surface should not be disturbed after application.
  • Do not apply on sand, loamy sand, or gravel soil.
