Since in these nurseries about one out of two black pepper plants examined had yellow leaves, this observation suggests that another pathogen must be the initial cause of the yellowing of the leaves. A likely pathogenic candidate is M. incognita which was extracted from every single black pepper...
pepper mild mottle virus (PMMoV) infection caused a significant decrease inCapsicum sp.leading to large economic losses. An isolate of PMMoV was obtained from naturally infected pepper plants, exhibiting different patterns of mottling, leaf distortion, yellowing, and stunting...
Carefully inspect the leaves, stems and fruit of your jalapeno plants for telltale signs of disease or pest problems, like cankers or spots on stems, wilting, yellowing or defoliating leaves, and growth on the jalapeno peppers themselves. Treatment depends on the specific cause. For some insec...
Similar results are observed in pepper plants infected with PHYVV. However, in this case the symptoms induced are usually milder than the ones induced by PepGMV and consist of vein yellowing as well as leaf curling [5]. In contrast, plants inoculated with the mixture PepGMV and PHYVV show...
The effect of salt stress was evaluated on a 1–5 scale (1: No effect (control plants), 2: Lower leaf wilting and salt stress (6–20%), 3: Leaf curling, wilting, and yellowing (21–50%), 4: Severe wilting, yellowing, necrosis, and drying of the leaves at 51–80% of the leave...
The function ofCaCIPK3in response to MeJA was also examined in leaves transiently overexpressingCaCIPK3. Leaf disks of the control leaves exhibited yellowing due to chlorophyll degradation, while those transiently overexpressingCaCIPK3remained green after MeJA treatment (Supplementary Fig. S2B). Collectivel...
In peppers, TSWV causes chlorosis, often sudden yellowing and browning, and chlorotic rings on leaves. Necrotic streaks may appear on stems and extend to the terminal shoots. Fruit of infected plants may show chlorotic or necrotic spots and streaks with mosaic and concentric ring patterns. ...

vines and to determine whether lime could be applied as a reflectant to protect the exposed plants. It was found that even with favourable soil moisture conditions the leaves of the exposed plants developed the symptoms of the physiological disorder of leaf yellowing leading to the formation of ...
Chilli leaf curl disease (ChLCD) is an important factor limiting chilli production on the Indian subcontinent and is caused by begomoviruses [6–8]. Symptoms of the disease are severe leaf curl with cup-shaped, upward curling leaves, yellowing, and stunted plant growth. Previously chilli leaf ...
