US approves Summit Agro’s Ranman 400 SC fungicide for downy mildew control in bulb vegetables

Summit Agro USA has recently announced that its RANMAN® 400 SC fungicide (cyazofamid) is now registered for control of downy mildew in bulb vegetables. This season, growers of onions, garlic, chives, and shallots can add a powerful and unique fungicide to their disease resistance management programs.

"Downy mildew can devastate a crop," says Fred Yates, Summit Agro marketing manager. "The fungus overwinters in bulbs left in the field or in cull piles, and when conditions are favorable, it produces spores that infect the leaves of onion plants. The disease may spread rapidly, leading to reduced bulb size and storage rot. However, this year, bulb farmers will have a new powerful tool -- with RANMAN."     
                                        
RANMAN's unique chemistry makes it ideal for disease resistance management programs that use either alternation or mixture strategies. A zero-day pre-harvest interval (PHI) allows application up to the day of harvest, for exceptional crop management flexibility, maximum yield, and profitability.

"As the only fungicide with a FRAC group 21 designation, RANMAN is in a class of its own," says Yates. "It's powerful and effective. It's compatible with a wide range of fungicides. And it's proven effective across many crops. Summit is proud that we can now make it available to bulb growers."

The new use registration includes all members of the Bulb Vegetable Crop Group 3-07. This group includes: Chive, fresh leaves; chive, Chinese fresh leaves; daylily, bulb; elegans hosta; fritillaria, bulb and leaves; garlic, bulb; garlic, great-headed, bulb; garlic, serpent, bulb; kurrat; lady's leek; leek; leek, wild; lily, bulb; onion, Beltsville bunching; onion, bulb; onion, Chinese, bulb; onion, fresh; onion, green; onion, macrostem; onion, pearl; onion, potato, bulb; onion, tree, tops; onion, Welsh, tops; shallot, bulb; shallot, fresh leaves; cultivars, varieties, and/or hybrids of these.
