Corn, Soybean, Wheat, and Forages Field Guide (PDF)
The newly revised Corn, Soybean, Wheat, and Forages Field Guide is a compilation of the latest research by Extension specialists from The Ohio State University in partnership with Pennsylvania State University.
Designed as a guide for scouts, crop advisors, and farmers, this handy spiral-bound book contains updated information and images to aid with insect, disease, and weed identification. Major revisions to the book include the latest fertilizer recommendations, broadleaf weed ID keys, and a manure sampling and manure applicator calibration section. Tar spot, a new disease to Ohio, is now included in the Corn Disease section.
The guide is divided into six sections: Corn Management, Soybean Management, Wheat Management, Forage Management, Weed Identification, and General Crop Management, which includes updated sampling information. The index at the back of the book can be used to quickly locate page numbers for your topic of interest while in the field.
