Mobile App For Calculating Plant Growth Regulator Applications Launched

The University of New Hampshire Cooperative Extension announced the launch of its first mobile app called “PGR Mix Master” on February 29, 2012. PGR Mix Master was developed at the University of New Hampshire with the support from Fine Americas, Inc and is available in Android, Blackberry and iPhone formats. The free application was created to be an easy-to-use tool to assist greenhouse personnel in calculating correct dilutions for plant growth regulators. PGR Mix Master is an extension of the popular web calculator PGRCALC that can be used on the home screen of a smartphone and is optimized for mobile devices.  PGR Mix Master is capable of calculating dilutions for all PGRs registered for greenhouse use.  The app can be downloaded by searching iTunes and the Android Market for Apple and Android devices, respectively, or visiting www.nhfloriculture.com for the Blackberry version.

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 […]
