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...
After decades of growing peppers, I’ve encountered just about every problem a gardener can face—wilting plants in the heat, leaves riddled with holes, stunted growth, and even entire crops lost to disease. Early on, I struggled with diagnosing issues quickly, often losing valuable growing time...
(2024) employed a CNN to classify various leaf diseases, including anthracnose, slow wilt, early stage of phytophthora, phytophthora, and yellowing as well as healthy leaves. The CNN model, pre-trained on the ImageNet dataset, was tested on 1800 distinct in-field images of all classes and ...
They are often recognized by the mines they cause on the leaves rather than by the pest themselves, which are particularly elusive. They are small black flies, about 2–3 mm long, with varying yellowing. Some of important species include L. huidobrensis and L. trifolii. The pest often ...

In a pepper plantation in Xinping County, Yunnan Province, southwestern China, virus-like symptoms such as necrosis, yellowing, mosaic patterns, malformation, and mottling were observed on pepper leaves (designated as LJ-6; see Fig. 1a). RNA from leaves was used to synthesize cDNA for high-...
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. ...
