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.

Agronomic Update on Powdery Mildew in Cucurbit Crops

Dr. Eric Tedford explains strategies for protecting cucurbits from Powdery Mildew, including a preventative treatment with PROLIVO® 300SC fungicide. Click here to learn more about PROLIVO.



PROLIVO fungicide provides excellent preventative control of Powdery Mildew in grapes, cucurbits, fruiting vegetables and berries. What makes PROLIVO especially innovative is that it offers additional disease protection of untreated leaf and fruit surfaces through redistribution on the leaf surface and vapor activity.

Two years of university trials demonstrate the power of KENJA® 400SC Fungicide for outstanding control of Botrytis (Gray mold)

SAN LUIS OBISPO, Calif — The results for the 2019 Cal Poly trials are in, and KENJA® 400SC fungicide once again outperformed other fungicides for control of Botrytis in strawberries. Data from both 2018 and 2019 trials demonstrate how well KENJA worked when matched up against other treatments for control of Botrytis (Gray mold).

There is a key factor that drives this consistent performance. It’s the unique molecular structure that distinguishes KENJA as one of the most active products in its class of chemistry.

This means California strawberry growers have a dependable tool available to them. One that has broad-spectrum activity not only for Botrytis, but also for control of Powdery Mildew and Anthracnose.

Getting on top of disease problems in strawberries is critical to preserving a high-value crop. SummitAgro encourages producers to talk to their PCA about how KENJA is an excellent fit for their disease control program, or click here to learn more.

New Fungicide Available to Grape Growers

This season, grape growers have an entirely new fungicide choice for the control of Powdery Mildew.

PROLIVO® 300SC Fungicide from SummitAgro USA is now available for use in wine grapes, table grapes and raisins, to control Powdery Mildew in multiple ways.

First, PROLIVO provides excellent preventative disease control at the onset of the disease epidemic.  In addition, with effective translaminar activity, PROLIVO provides additional protection to the untreated side of the leaf.  Finally, through redistribution on the leaf surface and vapor activity, PROLIVO protects untreated leaf and fruit surfaces.

Used as a preventative treatment, PROLIVO should be applied beginning with initial flowering or when disease conditions are favorable for disease development.  The activity of PROLIVO can be improved with the addition of an oganosilicant, non-ionic, or mixture adjuvant when used at the rates specified on the adjuvant label.

In addition to grapes, PROLIVO Fungicide is also registered for cucurbit vegetables (Crop Group 9), Caneberry Crop Subgroup 13-07A, Bushberry Crop Subgroup 13-07B, Small Fruit Vine Climbing Crop Subgroup 13-07D, and Low Growing Berry Crop Subgroup 13-07G, (except cranberry).

“Grape powdery mildew is one of the most significant diseases in terms of loss of quality and yield impacting growers today. ” says Jim Sturges, SummitAgro Regional Manager. “We’re proud to provide grape growers with a powerful new tool to control this devastating disease.”
