Summer Early summer opens the window for treating many perennial weeds, including Canada thistle, tall ironweed and western ragweed. Those undesirable weeds can leave your grass susceptible to weed pressure and leave your herd hungry. • Later-season weeds like ironweed and cocklebur can rapidly reach enormous heights, easily choking out grasses and becoming undesirable weeds in pastures. Be vigilant against these and other damaging weeds. • Don’t forget to keep an eye out on the ground for shorter weeds like leafy spurge, which may also start popping up. The weed reaches its true flower growth stage in mid- to late June, but all isn’t lost if it starts to flower. GrazonPD3™ herbicide provides the best leafy spurge control available and is effective on most other noxious and invasive weeds. • While you’re treating broadleaf weeds, resist the temptation to treat brush and other woody plants too early. Take time to ensure undesirable brush and wood plants are fully leafed out and actively growing, which usually doesn’t start before mid- to late June. • For renovation-type brush control programs, work with your aerial applicator to inventory species and develop a prescription tank mix that could include a foundational product such as Remedy®, Remedy® Ultra, DuraCor® or PastureGard® HL herbicides.
Fall The leaves are changing, and the temperature is dropping — fall is here. The season of recovery is the perfect time to take steps to help your grasses recover from spring and summer and prepare for winter. • Fall moisture will germinate new weed seedlings. Most are easier to control at this stage, which makes herbicide applications especially effective during this season. • Perennial weeds are also more vulnerable to fall applications. As the weeds prepare to overwinter, they intake winter food reserves — and your herbicide application. • Brush control also becomes more pleasant this time of year because of the cooler temperatures and more comfortable weather conditions. Dormant-season individual plant treatments, such as low-volume basal and basal cut-stump, can help improve pastures during the off-season. • Don’t forget to feed your pastures. Cool-season grasses benefit from fall fertilizer applications. UltiGraz℠ Pasture Weed & Feed lets you fertilize and control weeds in a single pass, saving you time and money.
