Plot size can influence yield benefits from fungicides

Fungicides are often evaluated in small-plot trials that are effective for assessment of disease control, but not very effective for assessment of true potential yield benefit.

Summit Agro USA R&D Manager Dr. Eric Tedford co-authored an article published in the journal Crop Protection investigating this question of whether plot size has an effect on the yield benefit of foliar fungicides. 

The authors’ research found evidence to support the idea that larger plots are more reflective of yield benefits that growers might recognize from fungicides compared to smaller plots. This is important for growers to remember when assessing fungicide yield data as they choose crop protection solutions.

Eric Tedford Delivers Presentation on RANMAN for Late Blight Control in Potatoes

Concerned about protecting your potato crop from Late Blight this season? RANMAN 400SC Fungicide offers remarkable control of this economically damaging disease. Learn how RANMAN can strengthen your efforts to fight Late Blight with this short video presentation by Dr. Eric Tedford, R&D Manager at Summit Agro USA.



Its unique chemistry makes RANMAN the perfect choice to include in your disease resistance management program. This is possible because of its compatibility with a wide range of fungicides.  RANMAN provides excellent protection against pink rot, Downy mildew, cavity spot and late blight. With it being the only fungicide in Group 21 RANMAN makes for an ideal resistance management tool.

Expanded RANMAN® 400SC Label

This season, growers of onions, garlic, chives, and shallots can add a powerful and unique fungicide to their disease resistance management programs. RANMAN® 400SC fungicide from SummitAgro USA is now registered for control of downy mildew in bulb vegetables.

“Downy mildew can devastate a crop,” says Fred Yates, SummitAgro 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.
