New research shows effective disease control in pome and stone fruits
RESEARCH TRIANGLE PARK, NC, January 26, 2012 -- Preliminary results from research conducted in 2011 demonstrate that Merivon® fungicide from BASF will be active on many fungal pathogens that impact pome and stone tree fruit crops each season. Research shows Merivon fungicide, which is expected to receive registration from the U.S. EPA in 2012, will provide long-lasting preventive and disease-stopping effects on specialty crops such as apples, cherries and peaches.
“Bringing the Xemium® fungicide molecule into the pome and stone fruit crops will be enormously helpful to growers,” said Curtis Rainbolt, BASF Technical Service Representative. “The diseases Merivon will treat rob growers of yield every year. These include powdery mildew, apple scab, brown rot, rusts and blossom blight. We’re eager to have this new tool available.”
Merivon is a premix composed of pyraclostrobin—the active ingredient in Cabrio® EG fungicide—and Xemium, a new active ingredient in the carboximide family. The active molecule in Xemium is a highly effective carboximide with high mobility. It is easily absorbed through the waxy layer on leaves and then is transported throughout the plant.
Research demonstrates that Merivon provides good coverage of the leaf surface and systemic distribution to ensure optimum coverage. Additionally, research shows Merivon can be applied up to four times per season on pome fruits and up to three times on stone fruits in rotation with fungicides with different modes of action.
Research trials were set to reflect the specific climate, moisture and common disease pressures in order to help develop sound recommendations for growers in the various geographies around the country.
Apple research trials in 2011 with Merivon were conducted in California, Michigan, New York, North Carolina, Pennsylvania and Virginia. Applications were completed at 7-10 day intervals. The research found apples treated with Merivon showed no incidence of apple scab, compared to 27.2 percent disease incidence when left untreated. The research also found a 1.5 percent incidence of powdery mildew in apples when treated with Merivon compared to 86.8 percent disease incidence when left untreated.
Research was completed in cherry orchards in Washington, California, Oregon and Michigan in 2011. Merivon fungicide was incorporated into a four-product treatment rotation that also included Pristine® fungicide. Cherries treated with Merivon showed 12.5 percent less incidence of powdery mildew than those treated with a current fungicide offering. Merivon also provided good control of Molinilia, cherry leaf spot and botrytis.
Merivon was tested in California, Georgia, North Carolina and Pennsylvania in 2011 for control of blossom blight, shot hole and powdery mildew in peaches. These diseases account for significant yield loss each year.
Trials included four treatments of Merivon: one each at pink, full bloom, petal fall and three weeks prior to harvest. Treated acres showed incidence reduction of as much as 50 percent.
“In studies dating back to 2009, we’ve found Merivon to be highly effective at controlling several diseases in key specialty crops,” Rainbolt said. “We continue to be impressed with the results, knowing this product will help protect tree crops to produce marketable fruit.”
