Floriculture Industry Working To Solve The Whitefly Problem
This summer, the floriculture industry has been faced with a dangerous new development — the detection of the Q-Biotype whitefly (Bemisia tabaci) in outdoor landscapes. It’s the first time that the Q-Biotype has been found in the U.S., outside of a greenhouse or wholesale nursery, since the pest was first detected on an ornamental plant in an Arizona greenhouse in December 2004. This year in Florida, there have been 47 detections of the Q since April, in retail nurseries and residential landscapes in 10 counties in Florida, from Miami-Dade to Duval County, primarily on hibiscus. Other hosts involved are crossandra, eggplant transplants, lantana, ficus, and porter weed. The detections have been in 17 retail nurseries, eight wholesale nurseries, 10 residential landscapes, and two agricultural fields. Other states have reported Q-Biotype detections this year, as well. The discovery of Q-Biotype whitefly in the landscape is troubling for the entire ornamentals industry, […]

Holistic, Integrated Approach To Pest Control Rooted In Research
Greenhouse growers have been practicing integrated pest management for decades, but it’s becoming increasingly more important with the continued scrutiny of conventional pest control by a number of “regulators” — government, retail, and consumers. I just returned from Meister Media Worldwide’s Biocontrols USA 2016 Conference, in Monterey, CA, at the beginning of March this year, which served 450 attendees and 50 exhibiting supplier companies. It’s clear from the presentations and the growing attendance at this specialized event — now only in its second year — that use of biocontrols in IPM will continue to be adopted widely, as more growers get past their personal hurdles of doubt and intimidation, and embrace a new way to approach pest and disease control. Many growers think of using biocontrols as an all-or-nothing approach, but ultimately, IPM is about balance. Growers will need to continue to focus on IPM, integrating chemistry with biology, because […]
