Mowing and burning Mowing breaks old stems into small fragments and helps prevent shading of favorable species. Mowing also stimulates perennial pepperweed plants to resprout and produce new growth. Combining mowing with herbicides has been shown to be an effective control strategy.
How do I get rid of pepperweed?
If your fields are full of vigorous sod-forming grasses, it will impede the spread of perennial pepperweed. Peppergrass control can also be achieved by planting herbaceous perennials in close rows, using shade trees and applying fabric or plastic mulches. You can also remove young plants by hand pulling them out.
How does pepperweed affect soil salinity?
Perennial pepperweed also acts as a “salt pump,” bringing salts from deep in the soil up through the roots and depositing them on the soil surface. The increased soil salinity further inhibits growth of existing native plants or prevents them from re- establishing in an infested area.
What kills white top?
If grasses are not to be taken out, the best selective herbicide is Telar® by DuPont. It is pricey, but very effective and label rates are at just one ounce of product per acre. GOOD agitation is required during application to keep the herbicide from settling out of the carrier water.
