It's always amazing to see apparently still-thriving winter annual weeds underneath the snow or following some really cold weather. Our best advice at this point on fall spraying is that once fields dry or freeze up enough to allow traffic again, there is still considerable benefit to applying herbicides for control of marestail and other weeds that persist through winter.

Winter is staking its early claim in many parts of the country, and for fall strip-tillers, it’s been a race to get strips built before snow permanently blankets their fields.
