“…The chili crop is susceptible to infection by various microorganisms such as fungi, bacteria, viruses, and nematodes, which can result in reduced yields (Shahbaz et al, 2015;Khan et al, 2018;Asghar et al, 2020;Tariq-Khan et al, 2020;Ali et al, 2022;Saba et al, 2022;Aslam and Mukhtar, 2023a, b;Zeeshan et al, 2023). Viral infections in plants are known to contribute to various factors (Ashfaq et al, 2014;Murtza et al, 2017;Ahmed et al, 2021;Naseer et al, 2021). The annual reduction of crop yields is caused by numerous viruses (Khan et al, 2018).…”

“…The utilization of resistant germplasm can effectively and sustainably manage plant viral infections over an extended period (Ahmad et al, 2021a). The effective management of diseases necessitates the identification of sources that are resistant to pathogens (Ashfaq et al, 2014;Aslam et al, 2017;Jafir et al, 2018;Asif et al, 2018;Ahmad et al, 2021b;Ahmed et al, 2021;Haq et al, 2022). The utilization of chemicals has been identified as an effective method for managing whiteflies and reducing the spread of viruses (Naseer et al, 2021;Ali et al, 2022).…”

The production of chili in Pakistan is currently facing a significant threat from Chili leaf curl virus (ChiLCV). A study was conducted in the crop growing seasons 2019-2020 and 2020-2021 at Ayub Agriculture Research Institute Faisalabad to assess the susceptibility and resistance of nine chili genotypes to ChiLCV. Each genotype was replicated three times by using the Randomized Complete Block Design. Weekly documentation was carried out to record the incidence and severity of the disease. During the first and second crop growing seasons, it was observed that, Tarapuri (78%, 76.9%), CH 107 (67.8%, 63.7%), Talhari (65.7%, 56.8%), CH 109 (52.7%, 54.4%), CH 108 (50.8, 51.1), and GSL-111 (42.6%, 39.5%) genotypes showed susceptible response to ChiLCV. The two genotypes Hybrid-46 (17.7%, 18.5%) and Hot Queen (15.5%, 13.4%) exhibited a moderately resistant response and only one genotype CBS1292 (40.7%, 39.1%) showed a moderately susceptible response against ChiLCV. The results of the screening experiment indicated that a majority of chili varieties exhibit susceptibility to chili leaf curl disease and the most of the germplasm is deficient in terms of providing protection against the disease. In addition, another study was conducted to evaluate the effectiveness of five insecticides, namely Acephate 75 SP, Emamectin, Imidacloprid, Diafenthiuron, and a combination of these insecticides, in managing percent disease incidence, reducing whitefly population, and enhancing crop yield. Among the various insecticides evaluated, Diafenthiuron exhibited the highest efficacy in reducing disease incidence (7.70%, 6.66%), reducing white fly population (1.80, 1.56), and increasing the yield of green fruit (120.71, 132.52q/ha) followed by combination of all of these inecticides, Imidacloprid, Emamectin, and Acephate during both crop growing seasons. This approach has proved a high level of safety and ecological compatibility, and it appeared to be a practical disease management tool.

“…Tomatoes lower the chance of developing heart and other harmful diseases in humans, because they contain vitamin A, C and essential minerals (Shidfar et al, 2011). Tomato fruit is known for its flavor, taste and nutritional benefits (Olaniyi et al, 2010;Naseer et al, 2021;Ahmad et al, 2021a). Tomato crop is easy to cultivate and produce large returns on annual basis mostly in hotter climates (Naika et al, 2005).…”

Fungal pathogens cause economically important diseases in tomato. Fungus Curvularia lunata has been reported the cause of tomato leaf blight and fruit rot. The objective of this study was in vitro evaluation of fungicides and biocontrol agents against leaf blight and fruit rot pathogen. For this purpose, surveys of different tomato fields were conducted for the collection of samples from infected tomato fields. For the isolation of C. lunata, potato dextrose agar (PDA) media was used. Pathogen was identified on genus level on the basis of macroscopic and microscopic characteristics. In vitro pathogenicity assays were conducted to check the virulence of isolates. Poison food technique was used for the evaluation of five different fungicides against C. lunata. All fungicides significantly inhibited mycelial growth of C. lunata at 3 rd , 5 th and 7 th day at different concentrations. Nativo showed best results against C. lunata and inhibited mycelial growth to 50.64%, 55.65% and 58.9% followed by Metalaxyl+Mancozeb 37.33%, 43.57% and 45.98% at 3 rd , 5 th and 7 th day, at 50, 100 and 150 ppm concentrations, respectively. Minimum percent inhibition was given by Topsin-M 33.43%, 36.15% and 43.9% at same concentrations. Dual culture technique was used for the evaluation of biocontrol agents (BCAs) against C. lunata. Trichoderma harzianum showed maximum antagonistic potential to suppress the growth of pathogen C. lunata (70.72%). All tested BCAs inhibited the growth of pathogen more than 60% in dual culture assays. The present study revealed that Nativo fungicide and BCA T. harzianum have the potential to control C. lunata.
