Effect of Tillage and Cultivar on Plant Population, Sudden Death Syndrome, and Yield of Soybean in Iowa
Field trials were established in a field with a history of sudden death syndrome (SDS) in Iowa in 2011 and evaluated for 5 consecutive years to determine the impact of tillage on SDS and yield. Kandel et al.'s findings suggest planting resistant cultivars can be an effective management tactic, but tillage does not improve SDS management.
Ralstonia solanacearum is ranked second among the top 10 most economically important plant-pathogenic bacteria. The objectives of this diagnostic guide are to provide adequate methods for isolation, storage, and identification and to discuss other relevant aspects related to this important bacterium.

PeerReviewed.gifSubmit Your Paper to Plant Health Progress
Plant Health Progress (PHP), a science-based, electronic outreach journal, is seeking high-quality manuscripts. Share your knowledge with plant health practitioners worldwide by submitting a manuscript today.
Focus on Cotton
The density and configuration of cotton in the field is crucial to achieving crop yield and economic goals, especially as seed costs increase. Curtis Adams draws on his work to better characterize the cotton yield response to plant population and discusses current recommendations, causes of stand loss, and crop production trade-offs with high and low populations.
Focus on Potato
Chad Hutchinson describes the ways Chloropicrin improves soil health, which is “the foundation of a positive crop production system.” Chloropicrin has been safely and successfully used as a preplant soil treatment for more than 60 years. The chemical compound suppresses soilborne pathogenic fungi while promoting soil growth and increasing beneficial organisms.
Focus on Soybean
The rapid adoption of dicamba-resistant soybean varieties (Xtend) to control herbicide-resistant weeds and the use of dicamba postemergence in these varieties has led to numerous incidences of off-target damage to sensitive soybean varieties. Bill Johnson explains how dicamba exposure affects non-Xtend soybean growth, development, and yield.
