New weed guides available Revised weed control publications for 2004 are now available through county Extension offices.
They are also available online from http://plantsci.sdstate.edu/weeds/.
South Dakota State University Extension Weed Specialist Leon Wrage said that the publications can help producers plan their weed control programs for this year. They also give an overview of available herbicide programs.
The information in the publications comes from nearly 200 field tests across South Dakota, he added.
The publications address topics such as herbicide products by trade name and chemical name, suggested rates based on SDSU tests, weeds controlled and a species rating table, restrictions on crop use and next rotation, conventional and herbicide-resistant crops, guidelines for additives, and estimated cost.
