Yield, quality and profitability of sensor‑controlled irrigation: a case study of snapdragon (Antirrhinum majus L.) production
Saavoss, M., Belayneh, B., Lea‑Cox, J., Lichtenberg, E. (University of Maryland), Majsztrik, J. (Clemson University)
On-farm research has found a number of advantages of sensor-based irrigation compared to current irrigation practices including reduced water application, disease incidence, production time and labor, and increased profitability. We examined the effects of sensor-based irrigation in a commercial greenhouse producing cut-flower snapdragons. We calculated changes in yield, production time, quality, cost, revenue and profit, using 3 years of data before and after implementation of sensor irrigation networks. Sensor-based irrigation increased revenue by 62% and profit by 65% per year. Sensor-based irrigation was also associated with increases in the quality and the number of stems harvested per crop.

First Report of Pythium aphanidermatum Causing Root Rot and Decline of Poinsettia in Maryland
Del Castillo Múnera, J. (University of Maryland) and C.L. Swett (University of California, Davis)
The publication is one of the outcomes from the statewide monitoring of water-borne oomycetes to provide critical control point assessment to nursery producers. Pythium aphanidermatum was isolated from poinsettia exhibiting root rot symptoms. Healthy poinsettia were inoculated in a greenhouse experiment with isolates recovered from the root rot resulted in wilting and root rot symptoms. P. aphanidermatum was recovered, confirming that it is a poinsettia pathogen in Maryland. This new information enables regional diagnosticians and crop advisors to provide more accurate information to producers, and facilitates research efforts to improve root disease management.

Next Generation Sequencing of Oomycete Communities in Nursery Irrigation Water
Eberhart, J., Funahashi, F., Foster, Z.S.L., Parke, J. (Oregon State University)
Our current research is focused on helping plant nurseries monitor oomycete pathogens in their irrigation water to determine the need for water treatment, evaluate effectiveness of treatment options, and enable selection of cost-effective ways to disinfest water. Once protocols have been fully developed and validated, Illumina sequencing has the potential to be a sensitive method to detect, identify, and estimate the relative abundance of oomycete communities from water samples. We will use this knowledge to help nursery managers make informed decisions about effective water disinfestation strategies, reducing the risk of establishment of plant pathogens.
