Fig. 4. Fungicide spray causes stigmatic papillae collapse. A, Localized fungicide‐spray damage to stigmatic papillae, with severely collapsed papillae occurring adjacent to normal, undamaged areas. Image taken 4 h after spraying with myclobutanil. B, Damaged papillae cells exhibit wrinkling and distortion of cell surfaces. Image taken 4 h after spraying with cyprodinil. C, Extensive damage with collapsed areas encompassing one‐third or more of the stigmatic surface. Papillae concave or totally flattened. Image taken 24 h after spraying with cyprodinil. D, Enhanced stigmatic exudate and cell damage can occur simultaneously. Image taken 24 h after spraying with iprodione.
