Face the Weed Challenge to Thin Wheat Stands
As winter wheat growers evaluate their crops to determine if they're worth keeping, Purdue Extension weed science specialist Dan Childs is offering weed-fighting advice for those who plan to keep their wheat.
"My guess is that with the current wheat prices, most will try to save poor stands," Childs says. "These poor stands will most likely be invaded by weeds, namely winter and summer annuals such as chickweed, giant ragweed and common ragweed."
Childs says herbicides will be necessary to ensure the crop's survival in weedy fields. "Growers will have to consider the cost of the herbicide and application when making their decision of whether to keep the stand," he says.
Childs recommends that growers read the table on weed options for wheat in the March 15 issue of the Pest and Crop newsletter available at Indiana Extension offices or on the World Wide Web at http://info.aes.purdue.edu/entomology/Pest&Crop/index.html
Childs urges farmers to hurry if they want to use one particular herbicide: "If using 2,4-D, it must be applied before the wheat begins to form joints in the stem."
