US weather patterns favor late-season soybean pests

To improve soybean yields and profitability in 2013, Syngenta encourages growers to continue scouting their fields for soybean pests. After a brief respite from heavy pest pressures last year, growers are seeing signs of substantial Japanese beetle and soybean aphid presence this season. Both are among the many prevalent and threatening soybean pests taking advantage of this year’s weather patterns. Growers are encouraged to increase scouting and consider utilizing Endigo® ZC insecticide to combat the increased threat of crop damage.
 
“Unfortunately, the likelihood of foliar insect damage occurring during the reproductive growth stages is high this growing season,” said Rich Lee, Syngenta agronomic service representative. “Although damage may vary, parts of the Midwest are already experiencing insect infestations. It’s important to consider potential losses and take the necessary preventive steps. Endigo ZC offers fast knockdown and long residual control of a broad spectrum of soybean insect pests.”

Reports of soybean aphid development came earlier and are more numerous than last season. According to Purdue University research, soybean aphids can be detrimental to soybean plants during the summer months because of the female aphid’s ability to reproduce rapidly when soybean field conditions are favorable. As aphids reach the economic threshold for treatment, researchers recommend growers consider a late-season insecticide application to help ensure soybeans yield strong.

While the Japanese beetle made an early appearance in 2012, its development was delayed this year due to the cooler spring temperatures. According to the University of Illinois Extension, the lifecycle of the Japanese beetle is 30 to 60 days, meaning populations may thrive much later into the fall this year. Japanese beetle injury builds on other stresses that soybeans are experiencing, such as moisture or disease, so growers may want to consider adjusting economic thresholds accordingly to prevent damage.

This season, growers can keep up to date on pest pressures that threaten yields. The Syngenta Pest Patrol hotline connects growers and retailers with expert advice and timely pest management recommendations from local agronomists and university entomologists. By calling (877) 285-8525 or visiting www.SyngentaPestPatrol.com, growers can hear the latest update for their area. Growers can also register to receive a text message when an update is posted to help stay one step ahead in the battle to manage pests.
