The wet spring and record planting delays mean soybean development is behind, but the South Dakota Department of Agriculture is not moving the cutoff date for spraying dicamba. South Dakota Soybean Association President and Colton farmer Jeff Thompson says June 30 is the last date for spraying the herbicide in the state.

He says to decrease the chance for application error he uses a weather app from SDSU when he applies dicamba.

Thompson says the wet spring is making weed control a challenge in crops, but he’s also seeing additional pressure on the edges of his fields.

Thompson says farmers that have prevented plant acres will also need to consider their weed control options. He was only able to plant half of his corn and about 60 percent of his soybeans.
