For the cleanest fields and highest profits, it’s time to refocus on weed control. A recent BASF poll showed nearly 80% of growers are changing their weed management programs to head off herbicide-resistant weeds – and with resistance confirmed across 31 U.S. states, a good scouting technique is a must for every field.
“Understanding the biology of the weeds already present in the field is the first step for farmers to gain control of their weed problems,” said Luke Bozeman, Technical Market Manager, BASF. “But scouting is equally important, and keeping an eye out for weeds that may have survived an early-season application is critical.”
Scouting has evolved from a task to a science. While there are many new technologies and custom weed identification tools that farmers, crop scouts and company agents use to quickly and accurately identify common weeds in their fields, traditional scouting techniques are still critical. Moving in a diagonal pattern across fields is the best approach to capturing accurate data of persistent weeds and gaining a broad sample survey.
Timing is essential for effective weed control and scouting should be done early in the growing season. As weeds get bigger they become more difficult to control and can continue to grow and produce seed. This can keep soil weed seed banks high and increase weed problems next year, contributing to crop competition and yield loss.
