The mission of the Southwest Purdue Agricultural Program is to maintain a safe, quality food supply and a healthy environment while supporting families and communities associated with the agricultural industry.


ChuckCharles Mansfield 

Charles Mansfield is the Agronomy Extension Specialist for southwestern Indiana. His focus is on small grains, primarily wheat and wheat cropping systems. Chuck also manages Purdue’s wheat variety testing program with three locations in southwestern Indiana. This testing program is done in cooperation with Extension Educators and landowners of the respective counties that host the variety test plot. In addition, Chuck is a regular speaker at the southwestern Indiana Diagnostic Training Clinic held biennially at the Southwest Purdue Agriculture Center. His topics include wheat production and management, and soils. In his effort of general outreach Chuck aids growers, industry personnel, and extension educators with general agronomic information and troubleshooting on the major agronomic crops – corn, soybean, wheat, and forages.

Evaluation of Foliar Fungicides and Genetic Resistance to Mitigate Head Blight and Mycotoxin Levels in Winter Wheat
Head Blight is a major disease of winter wheat in the humid Midwest. It can greatly reduce grain yield and grain quality. Reduction in grain quality due to the presence of mycotoxin results in significant price discounts to growers at the point of sale. This study is to evaluate several fungicide application strategies along with genetic resistance to reduce the incidence and severity of head blight as well as lower the level of mycotoxin contamination in grain.

Evaluation of Previous Crop on Performance of Double-Crop Soybean
This study is to evaluate yield and plant health of double-crop soybean following winter canola as compared to winter wheat. Growers in southwestern Indiana typically plant double-crop soybean in June after wheat harvest. Canola is harvested at the same time as wheat affording growers the opportunity to plant double-crop soybean; however, the effect of winter canola on double-crop soybean production is unknown.

Winter Wheat Variety Testing
Soft, red winter wheat is an important crop in southwestern Indiana with approximately 25 % of Indiana’s wheat crop being grown in this area. Industry representatives support the variety testing program by entering varieties that are commercially available to southern Indiana growers. It is done in cooperation with the Agriculture and Natural Resource Extension Educators and landowners in the respective counties that host the test plot.

The goal of my extension program is the dissemination of up to date technical information via my own research, Purdue University campus based work or other established programs.  Information exchange takes the form of in-season twilight meetings, winter technical meetings, field visits to commercial fields, grower office visits to SW Purdue Ag Center, phone calls, e-mails and extension publications.  In season I conduct diagnostic work in conjunction with the Plant Pest Diagnostic Laboratories in West Lafayette.  As with all extension programs sponsored by Purdue University, the programs I am involved in emphasize Integrated Pest Management (IPM).  An example of such a program is MELCAST, a weather-based disease-forecasting program (administered with Rick Latin) for the management of foliar diseases of muskmelon and watermelon


The focus of my research involves the management of vegetable diseases important in Indiana.  Fungicide trials on diseases such as gummy stem blight of watermelon, Alternaria leaf blight of muskmelon, downy mildew of pumpkin and early blight of tomato aid in the management of these diseases.  Other research concerns diseases that are not fully understood.  An example would be mature watermelon vine decline which has caused huge losses among Indiana growers.  I have also conducted research that has elucidated the pathogen race situation of Fusarium wilt of watermelon in Indiana
