Managing Corn Earworm Infestations In Louisiana Soybean Fields

Recently, there have been increased reports of corn earworms infesting soybean fields across the state. Corn earworm (aka bollworm or soybean podworm) can cause occasional but severe damage to soybean.

Don't Forget About Nematodes When Diagnosing Irregular Patches Of Poor Soybean Growth
