Effects of Fungicide Application on Root, Stem and Leaf Anatomy and Morphology of Bean (Phaseolus vulgaris L.) Plant

Abstract

The production of Phaseolus vulgaris L., an important legume cultivated in Türkiye, is negatively affected by yield losses caused by diseases such as anthracnose (Colletotrichum lindemuthianum (Sacc. & Magnus) Lambs. Scrib.) and rust (Uromyces appendiculatus (Pers.: Pers.)). In this study, the effects of foliar applications of a commercial fungicide containing 80% maneb, 16% manganese, and 4% zinc at different doses (0.5, 1, 2, 4, and 8 g L⁻¹) on the morphology and anatomy of root, stem, and leaf tissues of common bean were investigated. The results showed that high-dose fungicides caused leaf smut, spotting, and curling, as well as a reduction in leaf number and size. While no statistically significant change in root length was observed, stem length decreased significantly at higher fungicide doses. When anatomical data analyses were evaluated, that increasing fungicide concentrations led to significant structural changes in root, stem, and leaf tissues. The findings highlight the importance of appropriate management of fungicide doses by demonstrating that high-dose fungicide applications can cause adverse morphological and anatomical effects on bean plants.
