‘Help the farmer make the decision to replant or cut back’

LSU AgCenter weed scientists hope new predictive model for dicamba injury will be available in 2017.

Jim Griffin says he was surprised at how close the model he and graduate assistant Matthew Foster developed came – on average – to predicting the amount of yield loss from off-target or off-label applications of dicamba in soybeans.

Dr. Griffin, retired weed scientist with the LSU AgCenter in Baton Rouge, says the model isn’t quite as accurate on high yield losses vs. less serious injury, but that may not be a major consideration for farmers when their fields have been hammered by dicamba.

He and Foster discussed the model at the Louisiana Agricultural Consultants Association’s  Louisiana Agricultural Technology and Management Conference held earlier this year in Marksville, La.
