PMN Produces Two New ‘Focus on Soybean’ Webcasts


Slug Management on Soybean
This presentation by Dr. Ron Hammond at Ohio State University will help users in the Midwest, Eastern, and Mid-Atlantic regions manage their slug problems in field crops when using no-till production practices. It covers the basic biology of slugs and how it relates to grower practices, and then discusses an IPM approach to managing the problem. View presentation | View other soybean talks

Value of Residual Herbicide in Reduced Soybean Stands
This webcast by Dr. Vince Davis at the University of Wisconsin will help users in the North Central U.S. evaluate the importance of residual herbicide use in soybean systems to maximize profit and proactively manage for herbicide resistance. The cost of soybean seed is dramatically increasing, and this presentation discusses the interaction and relative importance of residual herbicide verses extra soybean plants in the canopy.

Late Blight Management, Forecasting Discussed in Latest ‘Focus on Potato’ Webcast


This talk by Dr. Bill Fry at Cornell will help users understand late blight forecasts and to manage late blight more effectively. First, the epidemiological basis for (potato) late blight forecasts is described. The presentation then describes a Decision Support System (DSS) that can be used in “real time” as an aid in scheduling fungicide sprays. The DSS integrates the effect of weather, host resistance and fungicide to assure adequate disease suppression. View presentation | View other potato talks

Bacterial Blight Screening, Management Highlighted in Latest ‘Focus on Cotton’ Talk


The presentation by Dr. Tom Allen at Mississippi State University will provide users with valuable information regarding the symptoms of bacterial blight of cotton as well as the mechanisms that allow the disease to occur, thrive and spread in a cotton field. In addition, viewers will be briefed regarding a new research project to provide cotton farmers with a valuable method to screen commercially available cotton cultivars for the presence of the bacterium in cotton seed.

New ‘Focus on Corn’ Webcast Offers Slug Management Tactics for No-Till Corn


This seminar by Dr. Ron Hammond at Ohio State will help consultants, growers, and other practitioners in the Midwest, Eastern, and Mid-Atlantic regions manage their slug problems in field crops when using no-till production practices. It will cover basic biology of slugs including life history and how it relates to grower practices, and then discuss an IPM approach to managing the problem. By the end of this presentation, the practitioner should know more about slugs in field crops, and be able to appropriately manage slugs. View presentation | View other corn talks

Perennial Weed Management is Focus of Latest Tomato Webcast


The webcast by Dr. Steve Weller at Purdue summarizes weed types, examples of problem perennial weeds and a discussion of techniques available for managing these weeds. The emphasis of this talk is on site preparation, elimination of perennial weeds before tomato crop planting and methods to manage perennial weeds in the tomato crop. Discussion will also include perennial weeds management in rotation crops, especially agronomic crops, as there are many more tools available for chemical management in agronomic crops.
