A broad spectrum, dual action, fungicide for potatoes
Washington Ag Today June 11, 2010 The forecast model is saying there will be potato late blight again this year in the Columbia Basin. Don Drader with Syngenta in Moses Lake expects there will be too, and this will be the first full year for commercial use of Syngenta’s Revus Top fungicide on the disease. Drader: “It is a product that has two different modes of action. It has a new chemistry, mandipropamid, which is a completely new chemistry to potatoes. And also a second of mode of action in it is called difenoconazole. Difenoconazole has been registered in other crops in different parts of the world but this is the first commercial registration to potatoes.” Drader says the two modes of action provides a broader spectrum of disease control. Drader: “One of those obviously would be late blight but other diseases that we are very effective on would include early blight and then brown spot or alternata, that seems like we are seeing more of that in some of our potato growing areas. But primarily we are getting activity on late blight.” Revus Top has what is called LOK + FLOW technology. Drader: “Locks or adheres very tightly to the leaf to give us the protectant and the flow or movement into the leaf to actually give us some curative or reach back of the product.” Drader says Revus Top has a short pre-harvest interval of 14-days.
