Scouting is Insurance to Protect Your Soybean Crop

Don’t let stealthy, unpredictable insect and disease pests steal yield.

Whether you grow conventional or double-crop soybeans, or both, each field you’ve planted required an investment of capital, labor and crop inputs. Monitoring and controlling weeds, insects and diseases throughout the growing season is vital to protect your investment and ensure you get the optimum return on that investment.

Weekly, in-season crop scouting should begin as soon as the crop emerges. Keep an eye out for weeds early in the season, because controlling weeds is most effective when they are less than 6 inches in height. Early control may allow lower herbicide use rates and also reduces the amount of nutrients and soil moisture weeds steal from the crop.

Resources help anticipate unpredictable pests

The occurrence of yield-reducing insect populations and diseases is unpredictable and often impacted by the weather, so weekly full-field scouting is important. For a better understanding of the insects and diseases expected or occurring in your area, local Extension agronomists and your Southern States representative are good resources. Also, before planting be sure to search online using the term “crop pest management resources” for your location and sign-up for pest alerts and updates available throughout the season.

Insect types coincide with plant growth stages

When scouting, remember the type of insects plaguing soybeans coincides with the crop’s growth stage. Foliar feeders include various worms such as soybean loopers, armyworms and green clover worms, plus several varieties of beetles such as bean leaf, cucumber, blister and Japanese beetles. Foliar feeders can begin feeding on leaves as soon as young plants emerge, while others are most severe in late July through September. Be especially vigilant in scouting double-crop soybeans for army worms since they are often found in small grain residue.

As soybeans reach the reproductive stage and begin pod set, look for pod-feeders such as stink bugs and corn earworm. Throughout the season, aphids are particularly nasty pests to watch for because they multiply very rapidly with populations reaching economic treatment thresholds in as little as three days. These sap suckers literally suck the sap out of the plants and also damage pods.

Stem feeders such as kudzu bugs are particularly dangerous. They use piercing, sucking mouthparts to tap through the veins of plants to reach the phloem, causing injury from nutrient and moisture loss. Yield losses of up to 47 percent have been recorded on untreated soybeans.

Watch for weather and environmental factors to spark disease occurrence

Many soybean diseases are endemic to specific geographies, but occurrence is often the result of weather or environmental conditions. Frogeye leaf spot is more prevalent mid- to late-season during warm, humid weather while white mold is more prevalent during cool, wet weather and within fields drilled or planted in narrow rows. Irrigated soybeans more frequently are infected by downy mildew.

Be sure to talk with your local Southern States Cooperative agronomy professional for scouting tips, economic treatment thresholds and the most appropriate products to control weeds, insects and diseases in your soybeans.
