Soybean Diseases: A Pictorial Guide For South Dakota, Lawrence E. Osborne, Darrel Deneke Jul 2010

Soybean Diseases: A Pictorial Guide For South Dakota, Lawrence E. Osborne, Darrel Deneke

SDSU Extension Circulars

This publication was assembled to provide growers and crop managers in South Dakota and nearby states with easy-to-use and handy diagnostic information for a number of major or potentially problematic soybean diseases. It is intended to provide a starting point for management decisions.

Best Management Practices For Corn Production In South Dakota: Recordkeeping, James A. Wilson, Kurtis D. Reitsma, David E. Clay May 2009

Best Management Practices For Corn Production In South Dakota: Recordkeeping, James A. Wilson, Kurtis D. Reitsma, David E. Clay

SDSU Extension Circulars

Recordkeeping is an important component of all crop production systems. The time that is spent maintaining careful records can help to improve the production, profit, and overall efficiency of the production enterprise. Records provide information needed to identify successes and failures.


Best Management Practices For Corn Production In South Dakota: Corn Drying And Storage, Richard E. Nicolai May 2009

Best Management Practices For Corn Production In South Dakota: Corn Drying And Storage, Richard E. Nicolai

SDSU Extension Circulars

The goal for a corn drying and storage system is to maintain grain quality without impeding harvesting or shipping. This chapter describes the factors that influence grain quality, proper handling techniques, drying procedures, storage management, and safety precautions.


Best Management Practices For Corn Production In South Dakota: Corn Grain Harvest, Daniel S. Humberg, Richard E. Nicolai, Kurtis D. Reitsma May 2009

Best Management Practices For Corn Production In South Dakota: Corn Grain Harvest, Daniel S. Humberg, Richard E. Nicolai, Kurtis D. Reitsma

SDSU Extension Circulars

Corn (grain) harvest can begin when grain moisture drops below 30%. However, most producers will allow corn to dry in the field until grain moisture is between 18 to 25%. Harvesting corn when grain moisture levels are high can result in excessive drying costs, kernel damage, and harvest loss from improper threshing. Allowing corn to stay in the field too long can result in excess harvest loss from stalk lodging, ear drop, or kernel shattering. An optimal harvest depends not only on the condition of the crop but also on the proper maintenance and adjustment of harvest and grain handling …


Best Management Practices For Corn Production In South Dakota: Corn Insect Pests, Michael A. Catangui, Billy W. Fuller, B. Wade French May 2009

Best Management Practices For Corn Production In South Dakota: Corn Insect Pests, Michael A. Catangui, Billy W. Fuller, B. Wade French

SDSU Extension Circulars

Historically, the major corn insect pests have been corn rootworms (northern and western), European corn borer, and black cutworm. Bt-corn hybrids are effective against most of these pests. However, Bt-corn hybrids are not effective against corn leaf aphid, corn root aphid, sap beetles, corn rootworm adults, grasshoppers, white grubs, wireworms, seed corn beetle, and seed corn maggots. These insect pests can reduce corn yields. This chapter discusses the management and biology of important corn insect pests commonly observed in South Dakota.


Best Management Practices For Corn Production In South Dakota: Soil Fertility, David E. Clay, Kurtis D. Reitsma May 2009

Best Management Practices For Corn Production In South Dakota: Soil Fertility, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Corn requires sufficient amounts of at least 14 nutrients for optimal production (fig. 7.1). Soil fertility strategies should consider soil residual plant nutrients, cost of fertilizer relative to the value of corn, and management techniques that increase efficiency.


Best Management Practices For Corn Production In South Dakota: Corn Diseases In South Dakota, Martin A. Draper, Marie A. Langham, Sharon Clay, Bradley E. Ruden May 2009

Best Management Practices For Corn Production In South Dakota: Corn Diseases In South Dakota, Martin A. Draper, Marie A. Langham, Sharon Clay, Bradley E. Ruden

SDSU Extension Circulars

Corn diseases can be separated into 1) seed and seedling diseases, 2) root-infecting nematodes, 3) leaf diseases, 4) rusts, 5) stalk rots, and 6) ear and grain molds. Yield losses can result from diseases directly reducing yields or from harvestability, spoilage, or marketing and/or use issues associated with mycotoxin contamination. See Table 9.1 for corn disease management information. Attention to optimal seed quality, hybrid selection, seed treatments, weed and insect control, crop rotation, soil fertility, irrigation, and prompt harvest can reduce disease impacts. This chapter discusses aspects of recognizing and managing South Dakota corn diseases.


Best Management Practices For Corn Production In South Dakota: Weeds And Herbicide Injury In Corn, Sharon Clay, Mike J. Moechnig May 2009

Best Management Practices For Corn Production In South Dakota: Weeds And Herbicide Injury In Corn, Sharon Clay, Mike J. Moechnig

SDSU Extension Circulars

This chapter addresses weed problems and herbicide injuries that commonly occur in South Dakota corn production. Photographs and information are provided to assist producers in managing weed pressure and to help identify herbicide injury symptoms resulting from improper application, unintentional exposure, or adverse environmental conditions.
