“…As a matter of fact, decreases in chlorophyll content has been noticed in Rhizoctonia diseased carrot (Ahmad et al, 2019 ), in cucumber affected both by R. solani and S. rolfsii (Kotasthane et al, 2015 ) and in soybean attacked by S. sclerotiorum (Vitorino et al, 2020 ). On the contrary, Trichoderma can enhance the phothosynthetic performances of the colonized plants by increasing their chlorophyll content and, at the same time, determining an improvement of their general physiological status (Singh et al, 2013 ; Doley et al, 2014 ; Kotasthane et al, 2015 ) exerting an antagonistic action with respect to the pathogen in promoting the vitality of the plant. Therefore, according to these inferences the plant functional imaging as applied here may return valuable information about how the biocontrol agents is working.…”

Research has been increasingly focusing on the selection of novel and effective biological control agents (BCAs) against soil-borne plant pathogens. The large-scale application of BCAs requires fast and robust screening methods for the evaluation of the efficacy of high numbers of candidates. In this context, the digital technologies can be applied not only for early disease detection but also for rapid performance analyses of BCAs. The present study investigates the ability of different Trichoderma spp. to contain the development of main baby-leaf vegetable pathogens and applies functional plant imaging to select the best performing antagonists against multiple pathosystems. Specifically, sixteen different Trichoderma spp. strains were characterized both in vivo and in vitro for their ability to contain R. solani, S. sclerotiorum and S. rolfsii development. All Trichoderma spp. showed, in vitro significant radial growth inhibition of the target phytopathogens. Furthermore, biocontrol trials were performed on wild rocket, green and red baby lettuces infected, respectively, with R. solani, S. sclerotiorum and S. rolfsii. The plant status was monitored by using hyperspectral imaging. Two strains, Tl35 and Ta56, belonging to T. longibrachiatum and T. atroviride species, significantly reduced disease incidence and severity (DI and DSI) in the three pathosystems. Vegetation indices, calculated on the hyperspectral data extracted from the images of plant-Trichoderma-pathogen interaction, proved to be suitable to refer about the plant health status. Four of them (OSAVI, SAVI, TSAVI and TVI) were found informative for all the pathosystems analyzed, resulting closely correlated to DSI according to significant changes in the spectral signatures among health, infected and bio-protected plants. Findings clearly indicate the possibility to promote sustainable disease management of crops by applying digital plant imaging as large-scale screening method of BCAs' effectiveness and precision biological control support.

“…Pakistan, cultivating Groundnut on 91.1 thousand hectares, contributes 74.8 thousand tons annually, reflecting an average yield of 821.1 kg/ha (Nawaz et al, 2022). Beyond its economic value, Groundnut is esteemed for its nutritional benefits, particularly in Ghana and India, where it serves as a nutritious staple supporting both income generation for producers and improved health for consumers (Anim-Somuah, Henson, Humphrey, & Robinson, 2013;Doley, Dudhane, Borde, & Jite, 2014).…”

Aflatoxins impact the entire food supply chain, from agricultural fields to processing facilities, markets, and consumer tables. In peanut cultivation, this threat poses a constant challenge throughout the cultivation, processing, and consumption stages. To confront this challenge, an exhaustive study was undertaken with the aim of investigating the effects of targeted soil amendments; namely, Vermicompost, Lentil crop residue, and Sulphate of Potash applied during the pivotal sowing phase at two distinct locations, Chakwal and Attock. The research includes meticulous groundnut sample analysis to quantify aflatoxin levels, revealing a significant reduction across all soil amendments compared to the control group. Vermicompost stands out as the most effective, achieving a remarkable 64.8% reduction, followed closely by Sulphate of Potash at 62.4%. Statistical analysis highlights non-significant differences among amendments. Beyond aflatoxin mitigation, the study underscores the dual benefit of these soil amendments, contributing not only to mycotoxin control but also enhancing overall crop productivity. Percent increase in number of grains per plant ranged between 58.82% to 43.53% whereas in hundred grain weight it ranged between 17.10% and 10.55%. In summary, the study emphasizes the importance of strategic soil amendments, particularly Vermicompost and Sulphate of Potash, in mitigating aflatoxin contamination in peanuts. The dual benefit of improved crop productivity adds significance to the findings, offering a holistic approach to address the multifaceted dimensions of aflatoxin challenges in peanut cultivation.

Bio-control of Stem Rot in Jerusalem Artichoke (Helianthus tuberosus L.) in Field Conditions

Stem rot is a serious disease in Jerusalem artichoke (JA). To reduce the impact of this disease on yield and quality farmers often use fungicides, but this control method can be expensive and leave chemical residues. The objective of this study was to evaluate the efficacy of two biological control agents, Trichoderma harzianum T9 and Bacillus firmus BSR032 for control of Sclerotium rolfsii under field conditions. Four accessions of JA (HEL246, HEL65, JA47, and JA12) were treated or notreated with T. harzianum T9 and B. firmus BSR032 in a 4 × 2 × 2 factorial experiment in two fields (environments), one unfertilized and one fertilized. Plants were inoculated with S. rolfsii and disease was evaluated at 3-day intervals for 46 days. T. harzianum T9 and B. firmus BSR032 reduced disease incidence by 48% and 49%, respectively, whereas T. harzianum T9 + B. firmus BSR032 reduced disease incidence by 37%. The efficacy of T. harzianum T9 and B. firmus BSR032 for control of S. rolfsii was dependent on environments and genotypes. The expression of host plant resistance also depended on the environment. However, HEL246 showed consistently low disease incidence and severity index in both environments (fertilized and unfertilized). Individually, T. harzianum T9, B. firmus BSR032, or host plant resistance control stem rot caused by S. rolfsii in JA. However, no combination of these treatments provided more effective control than each alone.
