Weeds that escape control can be a headache and an eyesore for growers, and in some instances, can affect crop yields under the right conditions. While later in the crop growing season, weeds can still threaten the overall health of the crop and be a problem next year in the field. Most of the time, the healthiest crop in the field isn’t corn or soybeans; it’s the weed itself as they have no competition for sunlight. Because it is late in the growing season, there are limited options for growers. The E4 Team will help demystify the different options available for both weed-infested corn and soybean fields.

Late-Season Weed Control Options for Corn

One of the easiest solutions for cornfields dealing with weed problems is to utilize the herbicide known as 2,4-D. The effectiveness of the late-season application of 2,4-D is dependent on the sensitivity of the weed to the herbicide and the maturity of the weed seed at the time of application. 

Late-Season Weed Control Options for Soybeans

Slow canopy development in a soybean field can leave the door open for weeds to re-emerge and infest fields once again. While late-emerging weeds don’t compete for the same resources at the same level as soybeans, in certain circumstances, the presence of weeds can impact yields, and if left unchecked, the unwanted plants could produce a high volume of weed seeds that could end up being distributed during harvest, potentially affecting next year’s crop. 

The total amount of glyphosate that can be applied to the RR soybean is limited. Always be sure to follow label instructions. For more information about topics such as weeds and crop management, please visit E4CropIntelligence.com.
