Old but Gold : Captan Is a Valuable Tool for Managing Anthracnose and Botrytis Fruit Rots and Improving Strawberry Yields Based on a Meta-Analysis

| Zusammenfassung: | Botrytis fruit rot (BFR) and anthracnose fruit rot (AFR) are diseases of concern to strawberry growers. Both diseases are managed mainly by fungicide applications from the nursery (plant production) to the end of the growing season (fruit production). In Florida, captan is the main broad-spectrum fungicide used to control BFR and AFR. It has been tested in many trials over the years in various programs in alternation with single-site fungicides or weekly applications. Due to its broad-spectrum activity, captan is a pivotal tool in fungicide resistance management, because resistance to several fungicides has been reported in populations causing BFR and AFR. Our objective was to determine the effectiveness and profitability of applications of captan for controlling BFR and AFR based on a univariate meta-analysis considering data from 25 field trials conducted from 2005 to 2021 in Florida. Captan applications significantly improved marketable yields and reduced BFR and AFR incidence during late- and total-season periods. Marketable yields were significantly improved even when the effect on disease control was not significant. Our results indicate 100% probability that weekly captan applications would return the investment during low, medium, and high strawberry pricing regimes, although the magnitude of the return will depend on strawberry market prices. However, the probabilities of reducing BFR, AFR, and culls were lower. Results from our meta-analysis demonstrate the value of captan as an important tool for strawberry growers. Captan applications, in addition to effectively controlling BFR and AFR and improving marketable yields, will result in investment returns at any strawberry price level |
