Years before a chemical comes to market, it must undergo thorough testing. Dr. Luis Canas, an associate professor of entomology and chair of the graduate studies committee at Ohio State University, helped conduct experiments on Hachi-Hachi SC prior to its release to the market.
Canas started his work in 2012 in the greenhouse labs at the university, years before the product would be released to the market. He applied Hachi-Hachi SC, the old formulation Hachi-Hachi EC and two other chemical compounds to gerberas. All of the compounds were evaluated as foliar applications.
Two applications of each chemical were made. “We made one application at day 0, before the experiment started, and on day 14,” he says. Based off those two applications, the chemicals were evaluated for their ability to control thrips.
“Hachi-Hachi did provide some good control. Based upon the results, I recommend it as part of a rotation. I think it should be part of the second group or products that growers employ,” he says.
Canas also works with several growers throughout Ohio. He says he’s received some commentary on the product from the facilities he talks with.
“Several have tried it and said that it was good in their facilities, and that Hachi-Hachi SC provided control,” he says.
