OHP Shares Augeo Results
For the last two years, OHP has been working extensively with growers and academic researchers trialing its new plant growth regulator Augeo. At American Takii, Dave Barcels trialed it on dark leafed seed geraniums, delphiniums and the vigorous Cadenza petunias, which are a hedgiflora type, like PanAmerican’s Tidal Waves. The goal is to induce more lateral branching. More branching means more flowers. The idea is to double the flowers without delaying the crop. “We’ve really learned a lot in two years,” Barcels says. “The grower feedback has been, wow! They’re trying it on verbenas, calibrachoas, veronicas and petunias. This is a new product for us, which is exciting, but the real acid test is the growers.” Recommended rates are 400-800 ppm on herbaceous crops and 800-1,600 ppm on woodier crops.

New Piccolo Plant Growth Regulator 10 Times Stronger Than Original
Fine Americas has launched Piccolo 10 XC plant growth regulator for use on bedding plants. Featuring a 4.0 percent concentration of paclobutrazol, the new Piccolo 10 XC is 10 times stronger than current 0.4 percent formulations of the popular plant growth regulator. “We believe new Piccolo 10 XC is a significant improvement over current 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, Johnson says the formulation translates to fewer plastic containers, lower shipping costs and a smaller carbon footprint. “One quart of new Piccolo 10 XC equals 2.5 gallons of our standard Piccolo formulation, making storage, handling […]

Avoiding Rookie Mistakes With PGRs
“Every grower moves the decimal point at some point,” Morris says. “Instead of putting a 1 down you put a 10. I laugh about it, because it happens. I don’t know a grower who hasn’t done it once. You’re in a hurry and you know better, but it still happens.” Fortunately, some PGR mishaps are correctable. In Morris’ case, applying 10 times the amount of Bonzi wasn’t the end of the world. Certain chemicals, she’s found, can help prevent simple mistakes from wiping out a crop. “I have growers who beat themselves up about it,” Morris says. “But did you learn something? As long as you learn from it and don’t do it again, it’s OK.” Even if a mistake isn’t correctable, the key is learning from it. All growers will make mistakesâ€“some may be mistakes to which you can look back and laughâ€“but taking those experiences and pocketing them […]

Which PGRs Growers Prefer
Imagine you only have the option of using one PGR in production for all time: Which product would you use and why? “Although there are newer products on the market, I have had great success with the paclobutrazol family of products, such as Bonzi and Piccolo. I use them as a spray on some varieties, drench on some plants and a sprench on others. It really keeps my annual bedding plants in check during our colder and cloudier months of January and February when plants in small cell packs and containers get out of control right before spring sales." – Michael Pawelek, Pecan Hill Nursery “We use [Bonzi], especially for Wave petunias – even growing Waves on the dry side or growing cool. We used B-9 on annuals many years ago until we got Bonzi down to an art.” – Robin Waldrop Sr., First Stage Greenhouse “First there was sliced […]
