“…In practice, the genus Alternaria depends in its pathogenesis on the resistance and sensitivity of the host (Meena et al, 2017a). The increase in disease is also influenced by various physical factors such as heat, light and pH (Jadhav and Wadikar, 2018). Therefore, we note a high incidence of fungal infection in plant species such as the rosa and the syngonium with thin leaves, while the species A. dianthi, A.alternata is absent in the yucca plant due to the thickness of its leaves and its resistance.…”

The pathogenic fungi causing leaf spotting of several species of ornamental plants were isolates, diagnosed and purified. a (229) fungal isolates belonging to several fungal genera was obtained and the species belonging to the genus Alternaria were selected to conduct experiments on them. Where (89) isolates of the fungal type Alternaria dianthi and (68) isolates of the type A.alternata were obtained in addition to three isolates of the type A.longipes and one isolate of the type A.radicine. The phenotypic qualities represented by the forms of colonies, which are considered evidence in classification and innate diagnosis, have also been studied, and the colors of colonies belonging to this genus ranged from dark olive to pale in addition to some other phenotypic qualities such as the emergence of the phenomenon of sectors characterized by some fungal isolates.

“…Globally, Asian countries are the largest producers of chili (Truong et al, 2013). In Pakistan, the thriving production of chili is affected by several factors including adverse ecological conditions, diseases, insects, and arachnidan pests (Khan et al, 2012;Zhani et al, 2013;Shahbaz et al, 2015;Asghar et al, 2020;Tariq-Khan et al, 2017, 2020Saba et al, 2022;Aslam andMukhtar, 2023a,b, 2024;Zeeshan et al, 2023). Among these, insects are the main constraints that significantly affect the quantity and quality of chili.…”

Chili (Capsicum annuum L.) is a crucially economically viable vegetable and spice crop cultivated worldwide. Numerous issues impact chili production, both vertebrate and non-vertebrate, leading to significant reductions in both quantity and quality. The chili thrips, Scirtothrips dorsalis, poses a serious threat to chili, causing approximately 50-70% yield loss in every season. In Pakistan, farmers frequently resort to using synthetic pesticides to control the pest population. Unfortunately, the injudicious use of pesticides results in environmental, soil, and water pollution, leading to hazards for humans, animals, and wildlife. This study employed a combination of eco-friendly tactics to suppress the thrips population. The lowest thrips population was observed in plots where maize was planted as a barrier for chili, followed by marigold cultivated as a trap. Maize exhibited a remarkable disruptive effect against the thrips population, acting as a barrier to restrict their entrance into the main crop. The combined release of the biocontrol agents Chrysoperla carnea and Coccinella septempunctata proved to be more effective against the thrips population than plots with a single bio-control agent. Among the natural remedies, neem seed kernel powder was the most effective in reducing the thrips population, followed by neem leaves extract and neem oil. Notably, neem oil showed the lowest reduction percentage of thrips compared to neem seed kernel powder and neem leaves extract. The cost/benefit ratio of Integrated Pest Management (IPM) plots compared to conventional plots revealed that the IPM plot had a lower estimated production cost (Rs. 19,277) and yielded 547 kg more than the conventional plot. Similarly, a higher cost/benefit ratio (3:13) was recorded in the IPM plot than in the conventional plot (1:36). IPM, through eco-friendly measures, proves to be an efficient approach to suppress S. dorsalis in chili crop.
