The use of weed-free seed can reduce weeds in pastures. Examine the seed tag carefully at the time of purchase to see how well or to what extent the seed has been treated for weeds. Certain weeds are prohibited by law in certain states due to their toxic nature and the law require that the seed be treated for these.
Mowing is among the most frequently used method of controlling the growth of pasture weeds, as cited by the University of Florida Extension. You can effectively reduce broadleaf and annul weeds better with mowing as compared to the grassy, perennial weeds. Consider related costs such as fuel price and comparison with other weed management options as well as viability on targeted weeds before opting for this weed control method.
It is sometime imperative to use chemicals for weed control. The selection of appropriate herbicides depends upon the nature of grain or grass in the pastures and the target weeds, as recommended by the University of Kentucky Extension. Read all labels carefully prior to selection and use.
