March 28, 2017, Calgary, Alta – Four new crops have been added to the Presidio fungicide label as the result of Pest Management Regulatory Agency (PMRA) minor use approvals.
Presidio is now approved for use on ginseng, tobacco, brassica leafy vegetables and greenhouse ornamentals for a variety of troublesome diseases. The PMRA has also approved Presidio for control of pink rot on potatoes.
“These Presidio label additions are really important news for Canadian growers that depend on minor use approvals to protect their high value crops,” says Maria Dombrowsky, horticultural specialist at Nufarm Agriculture Inc. “Now more growers can access Presidio as part of their integrated pest management (IPM) program with a unique class of chemistry for better resistance management.”
Presidio (Group 43) provides growers with preventive and some curative reach-back action against downy mildew and Phytophthora spp., including late blight, on a variety of crops. In addition to these new crops, Presidio is also registered for use on head, stem and root brassica, cucurbits, fruiting vegetables and leafy vegetables.
“Presidio offers a great new option for domestic potato growers managing pink rot,” says Dombrowsky. “Growers should check with their processors before using Presidio on potatoes, because maximum residue limits (MRLs) for potatoes have not been established in all export markets.”
