A pocket reference guide used by farmers to quickly identify and manage crop problems such as weeds, diseases and insects has been updated by Purdue Extension and is available.

The 2013 Corn and Soybean Field Guide is a 324-page book that contains information about everything from planting to harvest and features color photographs and reference tables to help farmers make fertilizer and pesticide application decisions. Updates from last year's guide include improved photographs and information about soybean vein necrosis virus, which was first confirmed in Indiana this year. Other topics covered include crop development, nutrient deficiencies, planting decisions, soil fertility and herbicide injuries.

The guide has been produced since 1988.
