Weed Competition with Soybean

​​

Weeds can reduce soybean yield by 1% per day if left uncontrolled after the V2 to V3 stage of soybean growth. University research shows that weeds emerging with the crop sho​uld be removed by the V2 or V3 stage of soybean development, when weeds are less than 4 inches tall, to minimize yield loss due to weed competition. Pre-emergence residual herbicides with a planned POST application is the best approach to avoid losses from early season weeds.
