Topkat® is a residual herbicide that can be used on all varieties of winter oilseed rape and sugar beet and fodder beet and may be applied pre or post-emergence of the crop. For optimum activity, application must be pre-emergence or early post emergence of the weeds.
Topkat® is taken up via cotyledons and roots and takes maximum effect before, or shortly after, weed emergence. Optimum results are obtained from applications made to fine, firm and moist seedbeds. The effects on the target weeds are the result of root inhibition and hormone-type effects.
Topkat® is suitable for use on all soil types as defined by Soil Texture (85) System, except sands and very light soils and soils containing more than 10% organic matter.
