Make sure you know what you are spraying!

June 15, 2006 -  Given the difficulties in getting POST herbicides applied and the aggressive weed growth which is effectively reducing crop yields, it seems that due consideration of the “details” has been avoided.  This has resulted in costly unintended consequences; loss of fields due to herbicide treatments contaminated with other herbicides or the application of the wrong herbicide (e.g. glyphosate applied to Liberty Link corn).  It is important that sprayers and nurse tanks be safely and thoroughly rinsed prior to switching herbicides and/or crops.  Also, take the time to check and make sure you are spraying the correct field, corn hybrid or soybean variety with the appropriate herbicide.
