Managing weed burden for existing pasture
If you’re looking for ways to get more out of your existing land and pasture this season, a herbicide spray programme may be just the solution you need.
Weeds like thistles, pennyroyal, water pepper, willow weed, buttercup, fleabane, hedge mustard and daisy germinate under existing pasture covers.
Once pastures are grazed, however, these weed seedlings and small plants are then exposed to sunlight and their growth takes off rapidly which will reduce the amount of quality pasture dry matter (DM) that can be grown productively in future seasons.
The best time to control weeds is between germination and flowering when they are growing fast and are still susceptible to herbicides. To get the best out of your spray application, graze paddocks before spraying to expose the target weeds, and to reduce clover leaf area which in turn minimises clover damage.
Let the paddock freshen for two to three days, and aim to spray as soon as possible thereafter, weather permitting.
Observe any withholding periods and restrictions before grazing treated pastures. Choosing the right product for your specific needs will come down to your weed species range, application method, clover selectivity requirements, timing, seasonality and location.
