Use of Ipm in the Control of Multiple Diseases in Maize: Strategies for Selection of Host Resistance
Maize (Zea mays) production in sub-Saharan Africa is constantly threatened by the potential outbreak of multiple foliar diseases such as maize streak, northern leaf blight, gray leaf spot, and rust. Improvement of host resistance to these diseases can provide an important component of integrated pest management (IPM). In this paper, conventional and molecular marker-assisted breeding approaches...
Leaf diseases, such as powdery mildew and leaf rust, frequently infect barley plants and severely affect the economic value of malting barley. Early detection of barley diseases would facilitate the timely application of fungicides. In a field experiment, we investigated the performance of fluorescence and reflectance indices on (1) detecting barley disease risks when no fungicide is applied an...
The olive (Olea europaea) leaf is considered an important traditional herbal medicine utilized against infectious diseases, and for the treatment of diabetes and hypertension. Moreover, olive leaf constituents have been related to cardioprotection, probably due to their association with cellular redox modulating effects. The pathogenesis of certain common diseases, including those of the cardio...
Peanut (Arachis hypogaea L.) remains an important agronomic crop in Alabama, Florida, and Georgia. In recent years, the value of Alabama’s 190,000-acre peanut crop has exceeded $120 million annually. However, the diseases early leaf spot, late leaf spot, and southern stem rot may greatly reduce the profitability of Alabama’s peanut crop due to lower yields and poorer nut quality (7). Also, fung...
Leaf spot disease of rough lemon and brown spot disease of tangerines caused by distinct pathotypes of Alternaria alternata, and postharvest fruit black rot disease caused by A. citri, are the three major fungal diseases of citrus. The pathogenicity and specificity for the pathogens of Alternaria leaf spot and brown spot diseases are associated with the production of different host-specific tox...
Plant diseases can be infectious type caused by pathogens or noninfectious type caused by nutrients deficiencies in plant, by waterlogged or polluted soil, and by polluted air. Detection of the diseases through human vision requires continuous monitoring of the leaves, stems of plants by the experts which is time consuming process. In this context Digital image processing plays a vital role in ...
Agriculture is the mother of all cultures. It played a vital role in the development of human civilization. But plant leaf diseases can damage the crops there may be economic losses in crops. Without knowing about the diseases affected in the plant, the farmers are using excessive pesticides for the plant disease treatment. To overcome this, the detected spot diseases in leaves are classified b...
Crop diseases can significantly impact crop yield and overall productivity, posing challenges for farmers in increasing output market prices. Early detection of these is crucial preventing further spread reducing their impact. To overcome this, researchers have utilized image processing technology, including deep learning techniques such as convolutional neural networks (CNNs), to detect diseas...
