Bayer debuts Calypso in Portugal
Bayer CropScience has “recently” debuted its neonicotinoid insecticide, Calypso (thiacloprid), for use on fruit in Portugal. It is for the control of pear psyllids ( Cacopsylla pyricola) and as an anti-resistance management tool. Bayer says that psyllids are a significant pest with strong resistance abilities. “The withdrawal of certain products from the market has left growers with essentially one available active ingredient, abamectin, increasing the risk of emerging resistance,” the company says. Calypso is also recommended for use in IPM systems against codling moths ( Cydia pomonella) and aphids, while the active ingredient is “harmless to bees”. The EU approved thiacloprid in 2004 with earlier registrations coming in South America and Japan.
