Knocking Back Kudzu Bugs in Soybeans
According to Clemson University Extension, average yield loss for untreated soybeans due to kudzu bugs has been observed at 20 percent in South Carolina and Georgia, but could be as high as 50 percent.
As kudzu bugs continue to spread, the threat they pose to soybean yields is becoming apparent to growers. Although these pests feed on the pesky vine for which they are named, their diet also includes legumes, especially soybeans. They feed on soybean stems and petioles by sucking nutrients with their piercing-sucking mouthparts, putting stress on the plant. Large, uncontrolled populations of these nutrient-robbing pests have definite potential to cut yield.
The first generation of kudzu bugs moves from kudzu to soybeans in early summer while the second generation migrates in late-July or early-August, making soybean crops susceptible to damage throughout the season. Because of this, it’s important that growers continually scout throughout the season.
Researchers throughout the Southeast are working to determine uniform threshold and control measures for the kudzu bug, while continuing to caution soybean growers of their yield-robbing potential. By combining three industry-leading technologies of lambda-cyhalothrin, thiamethoxam and the microencapsulation process of Zeon® Technology, Endigo® ZC insecticide can provide fast knockdown and long-lasting residual control, helping soybeans yield strong despite pest pressures.
