Abstract Plant diseases and poisonous insects are major threats to agriculture. As a result, detecting and diagnosing these illnesses as soon as feasible is critical. The ongoing development of major deep learning techniques has substantially aided in the diagnosis of plant leaf diseases, providing a potent instrument with incredibly exact results. Deep learning algorithms, on the other hand, are dependent on the quality and quantity of labelled data used for training. The lightweight parallel deep convolutional neural network is described in this study for detecting plant leaf disease. In addition, the Generative Adversarial Neural Network is introduced for creating synthetic data in order to overcome the data scarcity problem caused by uneven dataset size. The experimental results for two-class, six-class and ten-class disease identification of tomato plant samples from the Plant Village dataset are provided. The effectiveness of the proposed model is assessed using numerous performance measures, including accuracy, recall, precision and F1-score, and compared to known state-of-the-art approaches for tomato plant leaf disease detection. The proposed system provides better accuracy (99.14%, 99.05%, 98.11% accuracy for the 2-class, 6-class and 10-class) for tomato leaf disease detection compared with traditional existing approaches.

Abstract Damping-off diseases caused huge losses in crop production in numerous countries. Pythium aphanidermatum represents a major cause of these diseases. In the present investigation, two endophytic fungi Talaromyces omanensis and Aspergillus fumigatus isolated from a desert plant, Rhazya stricta, were investigated for their efficiency in suppressing P. aphanidermatum and its stimulated damping-off diseases in cucumber and radish. The results proved the ability of both endophytes to inhibit P. aphanidermatum growth in both solid and liquid forms, inhibit its oospore production, induce abnormal patterns in its hyphae and suppress its induced damping-off diseases. Moreover, T. omanensis produced an inhibition zone area against P. aphanidermatum and enhanced the fresh weight of cucumber and length, fresh weight and dry weight of radish. Further, A. fumigatus caused cellular leakage in P. aphanidermatum mycelium. The previous results were interpreted through the secretion of β-1,3-glucanase, cellulase and siderophore by both endophytic fungi.

Abstract Biological based formulation for inducing systematic resistance in the crop is a sustainable measure to control plant disease by utilizing the natural defence system of the host plant and meet the strategic needs of pesticide application for agricultural products worldwide. The crude extract of Ganoderma lucidum was used to induce systematic resistant in the chickpeas against the Fusarium wilt caused by soil-borne fungus Fusarium oxysporum (Schletend: Fr) f. sp. ciceri (Padwick) (FOC). The formulation was made using a crude extract of Ganoderma lucidum and an emulsion (water in oil: W/O); different dilutions of the formulation were made and applied to the chickpea and then challenged with the FOC. After the incubation with FOC, the chickpea was assayed for the enzyme involved in Phenylpropanoid pathways, i.e. Peroxidase (PO), Polyphenol oxidase (PPO) and Phenylalanine ammonia-lyase (PAL). The activity levels of these enzymes were changed in chickpea treated with the formulations as compared to the control (water treated chickpea). The GC-MS analysis confirmed bioactive compounds responsible for the enhanced level of enzyme in chickpea. The findings of the study would lead to the development of a bio-formulation based inducer of resistance molecules in the chickpea against the Fusarium wilt.

Abstract Sesame (Sesamum indicum L.) is a major oilseed crop in Pakistan, possessing high nutritional and pharmacological properties. Sesame is highly susceptible to pathogenic fungi such as Alternaria alternata. In the present study, metabolites extracted from culture filtrates of Alternaria alternata using hexane, chloroform, ethyl acetate, and petroleum ether solvents were evaluated for activity on seed germination and seedling health of sesame. Seeds treated with solvent-extracted metabolites from culture filtrates of A. alternata showed low germination as compared to control. Maximum reduction in germination was reported in seeds treated with petroleum ether culture filtrate followed by ethyl acetate, hexane, and chloroform. Shoot length and root length were also reduced in seeds treated with petroleum ether culture filtrate followed by ethyl acetate, hexane, and chloroform. Seedling treated with solvent-extracted metabolites from culture filtrates of A. alternata showed various symptoms including chlorosis, necrosis, discoloration, and wilting. From the present study, it is concluded that A. alternata contains certain metabolites which can reduce seed germination and are destructive for seedling stage of sesame. This is a baseline study to evaluate highly active metabolites which can be managed further to decrease sesame yield loss.

Abstract Cape gooseberry (Physalis peruviana) is one of the most important crops in Antioquia (Colombia). However, little is known about the viruses circulating in Cape gooseberry in the southwestern region of the province. In this work, the prevalence of seven viruses (PVY, PVS, PVX, TaLMV, PhyVNV, CGIV-1, and PMTV) was tested by RT-qPCR on seed samples, symptomatic and asymptomatic plants from commercial fields from this region, and virus genomes were investigated using high-throughput sequencing (HTS). The results showed the detection of all seven viruses in at least one sample. PMTV was the most prevalent virus as it was found in six seed samples, eight asymptomatic, and ten symptomatic samples. HTS analysis revealed the presence of a new virus species closely related to the genus Trichovirus and tentatively named as Cape gooseberry associated trichovirus (CgaTV). Near full-length genome sequences were obtained for P. peruviana infecting isolates of TaLMV, PhyVNV, and PVY.

Abstract White mould caused by Sclerotinia sclerotiorum affects the quality and quantity of bean crop. The aims of this study were to evaluate the incidence and severity of white mould disease in four districts of Kashmir valley and to characterize the morphological variability of 60 Sclerotinia sclerotiorum isolates from bean plants. Three bean fields per village and five villages per district were chosen randomly for sampling. The highest incidence among surveyed areas was found in Ganderbal (37.94%) and lowest in Shupiyan (19.98%). The disease severity was highest in district Ganderbal (15.54%) and lowest in district Shupiyan (7.94%). Single spore method was used to isolate the fungus. Sixty isolates of the causal organism were isolated from bean plants collected from the surveyed areas and pathogenecity test was carried out following Koch’s postulates. Morphological characters of the different isolates, like number of sclerotia per Petri plate, time required for formation of the first sclerotium and average weight and shape of the sclerotia were studied. Among sixty isolates of S. sclerotiorum isolated from bean, it was observed that 25% of the isolates had abundant mycelium, 25% had irregular mycelium, half of the isolates had thin mycelium. 75% of the isolates had white colour and 25% had beige coloration. 25% of the isolates had a round shape, and 75% had a diverse shape. Sclerotia were detected in 50% of the cases in a regular pattern along the colony edge, 25% spread throughout the colony, and 25% in concentric circles. The mean number of sclerotia per colony ranged from 11.68 (SS55) to 32.32 (SS26). The mean number of days for formation of the first sclerotium ranged from 9.3 (SS30) to 17.7 (SS60). The average weight of sclerotia ranged from 0.0918 (SS58) to 0.2475 (SS21). The variation in disease incidence across different sites and the morphological variation of the isolates can be due to differences in genetic constitution as well as environmental conditions.

Abstract Mulberry is an important food plant for domesticated silkworm (Bombyx mori L.). Among several root rot diseases reported in mulberry, black root rot caused by Lasiodiplodia theobromae has now emerged as a major disease. The survey was conducted and black root rot incidence was found to be maximum (51.7%) in Coimbatore district and minimum (14.1%) in Erode district. On PDA, L. theobromae covered Petri plate within three days with cottony white fluffy and slowly turned to black colour. All the four isolates were identified by molecular characterisation through PCR with ITS region and sequences were deposited in NCBI database. Among biocontrol agents screened, Trichoderma asperellum TRI 15 and T. virens TRI 37 were found to be inhibitory with 67.7% and 66.6% reduction in mycelial growth. Five mulberry varieties were screened, variety G2 showed resistance and V1 was highly susceptible.

Abstract Cercospora leaf spot induced by the fungus Cercospora beticola Sacc is the most important leaf disease of sugar beet (Beta vulgaris L.) in the world. Managing this enemy requires an integrated approach combining farming practices, resistant varieties, and chemical treatments. Indeed, chemical treatments against fungi provide control of the disease but generate another problem; the resistance to fungicidal molecules. Studies have detected the mutation points responsible for the resistance traits of this pathogen against the main fungicide groups (MBC, DMI, QoI). From the perspective of managing the resistance, alternative control methods such as the use of antagonists (fungi and bacteria).
