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.
