Seed is one of the largest input costs for growers, and establishing a healthy stand is critical to maximizing yields.
And with more farmers switching to no-till and planting earlier in the year, the risk of seedling diseases and stand loss increases.
Through the latest Focus on Corn presentation, titled “Seedling Diseases of Corn”, Dr. Martin Chilvers, Assistant Professor and Extension Specialist at Michigan State University, examines the identification and management of seedling diseases that can occur in corn.
In this 15-minute talk, Chilvers discusses:
This presentation is open access through February 2014.
Herbicide-resistant weeds pose significant economic and production challenges, particularly in specialty crops such as potatoes where weed control options are limited.
And as the threat of herbicide-resistant weeds continues to grow due to these limited modes of action, growers must focus on practical considerations of weed management that minimize the risk of herbicide resistance in weeds.
In the latest ‘Focus on Potato’ webcast, titled “Managing Weed Resistance to Herbicides in the Potato Rotation,” Dr. Jed Colquhoun, weed science professor at the University of Wisconsin-Madison gives users an update on herbicide-resistant weeds and a systematic way to assign herbicides to crops across the rotation in a manner that maintains weed control while utilizing multiple herbicide modes of action.

Whiteflies are known for their ability to carry and spread disease. Throughout the world, they’re responsible for hundreds of millions of dollars in crop damage each year.
In United States tomato crops, Whiteflies vector a number of damaging viruses. Among the most potentially troublesome in the Southeast is Tomato Yellow Leaf Curl Virus (TYLCV), which can cause yield losses of up to 90%.
In the latest Focus on Tomato presentation, titled “IPM of Whiteflies and TYLCV in Florida Fresh Market Tomato”, University of Florida entomology professor Phil Stansly helps consultants, growers, and other practitioners develop a balanced approach to management of this pest and this associated virus.
This integrated approach includes various biological, cultural, insecticidal, and host plant resistance strategies.
By the end of this presentation, viewers in tomato growing regions of the U.S. will understand the strengths and weakness of each approach and also have a roadmap for integrating them into a workable and sustainable system.
This presentation is open access through February 28, 2014.
Tomato Spotted Wilt Virus (TSWV) and the thrips that transmit it can cost growers millions of dollars in yield losses, not just for tomatoes but also for peanuts, tobacco, peppers, potatoes, and many other crops.
Dr. Scott Adkins, Research Plant Pathologist at the USDA Agricultural Research Service, addresses this important issue in the latest Focus on Tomato webcast, titled “Tomato Spotted Wilt Virus”.
This presentation will help consultants, growers, and other practitioners in the Southeastern U.S. and other regions of North America to identify and manage TSWV. The presentation also includes:
By the end of this presentation, viewers should know more about the tomato spotted wilt virus’ biology and its relation to virus management.
Tomato Spotted Wilt Virus” is open access through January 31, 2014.
