Spray Strategies for Strawberry Disease Control in South Carolina
Guido Schnabel, Extension Plant Pathologist Disease management is essential for growing high-quality strawberries in plasticulture. While Botrytis fruit rot (BFR) is a disease you can expect every year, Anthracnose fruit rot (AFR) and the more recently introduced Neopestalotiopsis fruit and crown rot (Neo-P) may or may not appear (Fig. 1). This largely depends on how…

2025 Recommendations For Fall Chemical Treatments In Strawberry Crops
By Guido Schnabel, Clemson University; Phil Brannen, University of Georgia; Bill Cline and Caleb Bollenbacher, North Carolina State University Whether or not Neopestalotiopsis (Neopest) will harm your strawberries this season depends on many factors – including the quality of the transplants, the cultivar, sanitation practices, soil inoculum levels, weather conditions, and the fungicides you use.…

Biologicals and Their General Performance Against Strawberry Diseases
Johanna Wesche and Guido Schnabel, Clemson University “Do biologicals work?” That is a frequently asked question coming not only from strawberry growers, especially in light of increasing resistance issues with many of the conventional fungicides and the fungicide insensitivity of Neopestalotiopis sp. In our recent article, “Biologicals Made Easy: Grouping and Understanding Biological Fungicides,” we…

And So It Begins…Neopest is Starting to Show Up.
By Guido Schnabel It is early October 2024 and as feared and expected, we are starting to see Neopestalotiopsis symptoms in strawberry fields. The leaf in Fig. 1 (left) displays leaf necrosis and was collected from a South Carolina farm October 4, 2024. Necrosis on leaves can be caused by many things, but if you…

Efficacy Trials with Biofungicide Howler EVO against Strawberry Diseases
By Guido Schnabel, Jeffrey A. Hopkins, and Johanna Wesche Recently, the article Fungus-Based Biological Control Agents: How Useful Are They for Strawberry Disease Management? was published. The article reported our first experience with yeast-based biological control agents (BCA) against Botrytis fruit rot (BFR) and Anthracnose fruit rot (AFR) of strawberry. The trials were conducted at the…

Recommendations for Fall Treatments in Strawberry Crops with Known Presence of Neopest
Guido Schnabel, Clemson University; Phil Brannen, University of Georgia; and Bill Cline, North Carolina State University Whether or not Neopestalotiopsis will substantially harm your strawberries this season depends on many things, including the cultivar, sanitation practices, initial inoculum levels, weather conditions, the fungicides you apply, and application timing. This article focuses on chemical management options…

Fungus-Based Biological Control Agents: How Useful Are They for Strawberry Disease Management?
From Guido Schnabel, Jeffrey A. Hopkins, Jim Faust, and William Gura Biological control agents (BCAs) are being promoted for disease management in fruits, nuts, and vegetables but very little data is available about their efficacy especially when it comes to preharvest field performance. The Schnabel lab has investigated yeast-like fungi and true yeast BCAs, namely…

Dramatic Neopestalotiopsis Disease in Strawberry Nurseries
From Phil Brannen (UGA Plant Pathologist) and Guido Schnabel (Clemson Plant Pathologist) Neopestalotiopsis fruit rot and leaf spot is already making headlines for this coming 2024-2025 season. As many strawberry producers are aware, some nurseries are already “ringing the alarm bells”. There is a major pass through to strawberry nurseries and producers through use of…

2022 Strawberry Season Stats
In the Fall of 2022, Extension Agents throughout South Carolina surveyed growers on specialty crop acreage for the year. This was the first year of what is expected to be an annual survey. For this first year, data was collected for six crops: collard greens, lima beans, peaches, strawberries, sweet corn, and watermelon. The goal…
