Ranman Fungicide Registered For Downy Mildew Control In Bulb Vegetables

Posted by Rosemary Gordon|April 25, 2016

This season, growers of onions, garlic, chives, and shallots can add Ranman 400 SC fungicide from Summit Agro USA to their crop protection arsenal.

“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.”

Ranman’s chemistry is said to be 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 crop management flexibility, maximum yield, and profitability.

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.
