PEST IDENTIFICATION:
CORN, SOYBEAN, and GRAIN SORGHUM
COURSE SYLLABUS
Course Description
Corn Insect Pests. This course goes over in detail the many insects that threaten corn yield. Each species is identified according to various stages of maturity, the signs and symptoms exhibited, and the type of biological, cultural or chemical control recommended for each.
Soybean Insect Pests. This course details the various types of insects that affect soybeans, including early-season insect pests, stem and petiole feeders, and defoliators. Treatment and control strategies for specified insects within these groups are detailed throughout this lesson.
Grain Sorghum Insect Pests. Sorghum represents a large portion of the U.S. export industry. It is a versatile crop that is used as a grain, forage or sweet crop. It is subject to infestation by a variety of insect pests. Good production practices can help reduce infestation when sampled regularly from emergence to maturity. This course will outline how to manage for these pests in a timely and efficient way.
