Protect and Nourish Double Crop Soybeans

Insects are a big issue on second-crop soybeans, according to Darrin Holder, regional product manager, WinField. “As corn and cotton start to desiccate, cotton boll worms (also known as corn ear worms and tobacco budworms) look for another food source. Second-crop soybeans provide an inviting source of food for bollworms and other insects.

“With a shorter development period than full-season soybeans, it’s important to protect every pod,” he adds.

Scout for Insects Regularly
Holder advises farmers to monitor fields for damaging insects throughout the season and apply appropriate insecticides when economic thresholds are met.

“Getting insecticides deep within the crop canopy where insects thrive is the key to effective protection,” Holder notes. “Adding an adjuvant to the spray mixture promotes good plant coverage throughout the canopy and minimizes drift.”

Maintain Nutrition Levels
Ensuring second-crop soybeans have adequate nutrition helps optimize production. “Farmers miss the boat when they rely solely on leftover plant nutrients from the wheat crop,” Holder says. “Take tissue samples at key stages to identify nutrient deficiencies, such as potassium, manganese or zinc, while there’s time to apply missing nutrients and protect against yield loss.”
