OHP To Show Off Plant Growth Regulators At California Spring Trials 2012
OHP has announced its participation in the California Spring Trials from March 23-31, 2012. Returning to the trials again this year, OHP will showcase the results of its plant growth regulators (PGR) on perennials and annuals such as lantana, geranium, petunia, calibrachoa, sedum and pennisetum (grass) at American Takii in Salinas. In addition, OHP will demonstrate the effect of its PGR Augeo on no-pinch poinsettias. OHP Senior Technical Manager Dave Barcel will coordinate the display, evaluating the performance of the OHP’s PGRs B-Nine, Cycocel, Paczol and Augeo on the many quality varieties of American Takii. “We feel very privileged to be able to be a small part of the event,” notes Barcel, who will be participating in his 17th Spring Trial. “American Takii has graciously agreed to provide us an expanded demonstration area for this year’s trials. They are a great host and destination spot.” The annual event draws attendees […]

Height Control For Easter Lilies
Flurprimidol drenches have been shown to successfully control height of oriental lilies and Dutch bulbs such as hyacinth, narcissus and tulips, but there is no data that shows how effective flurprimidol drenches are on Easter lilies. Researchers decided to find out.

Piccolo 10 XC Receives California Registration
Piccolo 10 XC, a plant growth regulator (PGR) from Fine Americas, is now registered for use in California. Featuring a 4.0 percent concentration of paclobutrazol, Piccolo 10 XC is 10 times stronger than standard 0.4-percent formulations of the PGR. “We’re excited that California ornamental growers now have access to Piccolo 10 XC, a significant improvement over previous paclobutrazol formulations,” says Greg Johnson, Fine Americas president. “Since it comes in a true solution instead of a suspension, Piccolo 10 XC overcomes the potential settling problems associated with older paclobutrazol products. “From a grower’s perspective, that means there is no need to shake the container prior to use in order to ensure uniform distribution of the active ingredient. In addition, the super-concentrated formulation translates to fewer plastic containers, lower shipping and storage costs, and a smaller carbon footprint for our industry.” Kevin Forney, technical services manager for Fine Americas, notes that Piccolo […]

SePRO: Avoid Hachi-Hachi On Colored Poinsettias
SePRO is voluntarily restricting the use of Hachi-Hachi on poinsettias with bracts in color after trialing the product in university trials and discovering some cultivars are particularly sensitive to it. A label change could not be made in time to deliver the message to growers, so SePRO is actively communicating the restriction to growers itself. The Hachi-Hachi label lists poinsettias as an approved crop for application based on trials of a limited number of poinsettia cultivars–with bracts not in color. SePRO also discovered in recent trials that some salvia and gypsophilla species can be harmed. Label changes have been submitted to the Environmental Protection Agency restricting the use of Hachi-Hachi on those two crops. Additionally, SePRO indicates ageratum, colocasia, geranium, lobelia, pansy (flowers), verbena and vinca sustained temporary injuries after Hachi-Hachi was applied. Before launching, SePRO was aware of potential injury to impatiens and New Guinea impatiens. Label restrictions were […]
