SOYBEAN INSECT CONTROL RECOMMENDATIONS

Christian H. Krupke, John L. Obermeyer and Larry W. Bledsoe, Extension Entomologists


Read and Follow ALL Label Rate, Application, and Use Directions

This publication is intended to aid pest managers in treating pest infestations in soybean during the growing season and in situations where replanting is needed. Consequently, many current preventative pest management decisions that are made pre-planting (e.g., seed-applied insecticides) are not included in this list.
