Recently, the Weed Science Society of America (WSSA) and the Southern Weed Science Society (SWSS) held their 2016 annual meeting in a joint meeting between the two organizations. The event took place on February 8-11, 2016 at the Sheraton Puerto Rico Hotel and Casino.
Seventeen members of Monsanto’s Technology Development Group traveled to Puerto Rico to attend the event. One notable participation was from Alejandro Pérez-Jones, Research Scientist at Monsanto Chemistry Technology, who co-chaired the agronomic crops program committee and moderated two sessions on the subject. A paper Alejandro co-wrote, titled Metribuzin Provides Cost-effective Residual Control of Resistant Amaranthus and Other Problem Weeds in Soybeans was also part of the program discussion.
Dr. Wilfredo Robles, Associate Professor and Weed Science IR-4 State Liaison at the University of Puerto Rico Mayagüez Campus and the Agricultural Experiment Station in Corozal, who also served as the WSSA/SWSS annual meeting local arrangements committee chair, explained the safety and comparatively low level of toxicity of glyphosate and glyphosate-based weed control products. Glyphosate has lower toxicity levels than table salt, acetaminophen, aspirin, caffeine, and nicotine, Dr. Robles explained.
