Cal-Poly Students And Faculty Ask Industry To Help Save Horticulture Facilities
California Polytechnic State University, San Luis Obispo, has released an update to its Master Plan that indicates that almost all of its orchards, horticulture facilities and field sites could be repurposed for buildings, including residential, and/or recreational space. According to a letter from Scott Steinmaus, the horticulture and crop science department head, the proposed changes directly affect the current orchard plantings and other long term plans for the department. The department is committed to making sure that its facilities remain invaluable teaching environments that enable its students to learn about crop, fruit and horticulture production, food safety and pest protection, in addition to providing sites for externally funded research projects that benefit the industry. Industry members are invited to submit comments to the university. According to Steinmaus, a recent eMail to the Cal-Poly community from the university president indicates that all of the input gathered through the end of May will be studied by the planning […]

Growers Working Hard To Protect Pollinators — And Their Businesses (Opinion)
Editor’s Note: This editorial was written and published just prior to the news coming out about Lowe’s phasing out neonicotinoids by 2019. However, that news doesn’t change the fact that growers have a long history as good stewards of their land and of the environment. As evidenced by the 2015 Top 100 Growers Report, the nation’s largest growers continue to adapt their production practices to be cognizant of environmental factors, worker safety, retailer preferences and consumer concerns. In light of Lowe’s announcement, growers who produce for the retailer are certainly working toward that mandate; but they’re also hopeful that the research currently underway will provide scientific reason for decisions made on production going forward. When the news broke last year that growers would be required to label plants treated with neonicotinoids at The Home Depot, and that other retailers were mandating growers to produce crops without neonics, I sucked in air and […]

SAF And AmericanHort Ask Government To Take Ralstonia O…
The Society of American Florists (SAF) and AmericanHort want Ralstonia solanacearum, Race 3, Biovar 2 (R3Bv2) taken off a list of animal and plant diseases that the federal government has determined could be misused as terrorist weapons. SAF and AmericanHort submitted formal comments together on the horticulture industry’s science-backed position on the matter. According to Lin Schmale, SAF’s senior director of government relations, extensive research has proven R3Bv2 does not belong on the government’s list of animal and plant diseases that can be misused as terrorist weapons. Every two years, USDA’s Animal and Plant Health Inspection Service (APHIS) requests a public review of the Select Agent list, asking for comments on whether plant or animal diseases should be taken off the current list or added to it. In the floral industry, R3Bv2 can have a devastating impact on geranium (pelargonium) crops, Schmale says, and both the potato and tomato industries also could be adversely affected by introduction […]
