It is also known that UV‑C radiation can have an effect on stimulating plant defense. In this study, we used the phytopathogen <i>Phoma lingam</i> as a model organism to examine UV‑C at a wavelength of 254 nm application as an alternative to control this pathogen in <i>Brassica napus</i>. The aim of the study was to determine direct effects on the pathogen and indirect effects of stimulating the plant defense. Mycelia of <i>P. lingam</i> were grown <i>in vitro</i> and treated with different doses of UV‑C (0.015–1.57 kJ/m²). Mycelia diameters were then measured 1, 2, and 7 days after UV‑C treatment. In the <i>in planta</i> tests, cotyledons were injured by a needle and inoculated with 10^<i>6</i> spore suspension of <i>P. lingam</i>. To determine the direct effects the oilseed rape seedlings were treated with different UV‑C doses (0.2–1.5 kJ/m²) 1, 3, or 7 days after inoculation with <i>P. lingam</i>. To investigate the indirect effects the UV‑C treatments (0.2–1.5 kJ/m²) were applied 1, 3, or 7 days before inoculation with <i>P. lingam</i>. The <i>in vitro </i>experiments showed a significant reduction in mycelia growth on agar plates one and two days after UV‑C treatment. However, the fungal growth recovered; after 7 days no significant differences were detectable. The <i>in planta</i> results showed an effect on disease severity affected by the application time of UV‑C treatment and the applied UV‑C dose. UV‑C application 1 day before inoculation significantly increased the disease severity. Whereas, UV‑C treatment 7 days before inoculation with a UV‑C dose of 0.8 kJ/m² reduced the disease severity by 44%. If the UV‑C application was done after inoculation, the disease severity could be reduced by approximately 68% at a dose of 0.8 kJ/m² 1 day after inoculation.

Among physical barriers, chain-linked fencing, electric fencing, and nylon net, each at a height of ≥ 7 feet, had given promising results by providing complete protection for ≥ 2 year with a single application cost. Whereas barbed wire fencing and electric fencing at a height of 4–5 feet were not very effective against these animals, as they easily crossed fencings at lower height. All these physical barriers were not cost effective except in maize crop, which is the most preferred crop by blue bull. Bioacoustic device and reflective ribbon successfully reduced animal visits or percent damage and provided short term relief; however, after some time, animals developed habituation against these methods. Among chemical repellents, RBF significantly reduced the percent crop damage, was cost effective and remained operative for 21–69 days, while phenyl and neelbo exhibited effectiveness for only 7–14 days. Thus, this study suggests that while comprehensive damage prevention by physical barriers might be difficult or unaffordable for farmers, the use of repellent based formulation at vulnerable stages of crops can prevent damage for longer durations.

Chemical seed and seedling treatment methods are commonly employed for managing bakanae disease, however, very less information is available on spray treatments. Our study aimed to assess the effectiveness of various fungicidal spray in field conditions for managing bakanae disease and their impact on basmati rice yield and related characteristics. Seven fungicides, along with a pathogen-inoculated control, were evaluated as foliar treatments during the <i>Kharif</i> season of the year 2021 and 2022. A combined analysis of data from two years showed that T₁ (Carbendazim 50% WP) had the lowest disease incidence at 44.68%, demonstrating a significantly high percentage disease inhibition of 44.08%. Following closely was T₄ (Tebuconazole 50% + Trifloxystrobin 25% WG) with a disease incidence of 50.00% and a corresponding percentage disease inhibition of 37.37%, while, maximum disease incidence of 79.84% was recorded in control treatment (T₈) followed by T₅ (Copper oxychloride 50% WP). Further, significantly high grain yield was obtained in Carbendazim 50% WP treatments (219.37 g/m²) followed by Tebuconazole 50% + Trifloxystrobin 25% WG (212.00 g/m²). Additionally, a quantitative polymerase chain reaction assay on harvested grains with <i>Fusarium fujikuroi</i> specific marker revealed least pathogen colonization in harvested seeds of Carbendazim 50% WP treatment (T₁), with a Ct value of 33.763 (copy no. 4.88E + 10), followed by Tebuconazole 50% + Trifloxystrobin 25% WG (Ct value 33.752, copy no. 4.94E + 10), conversely, Copper oxychloride (T₅) demonstrated the least effectiveness with highest pathogen load (copy no. 9.44E + 13). Based on our findings, we recommend the use of Carbendazim 50% WP or Tebuconazole 50% + Trifloxystrobin 25% WG for the management of bakanae disease as foliar spray (2 sprays) treatments (First spray after 15 days of transplanting; second spray at maximum tillering stage (around 25–30 days post I^st spray)) showing low AUDPC and high yield compared to inoculated control. Further, fungicidal spray reduced the infected seed percentage and carried less inoculum in next season.

Light plays a significant role in the growth and development of crops, as well as the prevailing environmental conditions during the growth period. This study aimed to investigate how fungal symbiosis affects the growth, biochemical properties, and grain yield (GY) of soybeans under various light intensities. The experiment was designed as split-plot based on randomized complete block design with three replications in the research farm of Sari Agricultural Sciences and Natural Resources University (SANRU) in 2022. The main factor consisted of five light intensities (20, 40, 50, 70, and 100% of natural light), and the sub-factor involved four levels of fungal inoculation (control, inoculation with <i>Bjerkandera adusta</i> (ST1) or <i>Chaetomium globosum</i> (SE2) fungi, and co-inoculation of ST1 + SE2). According to the results, as the light intensity decreased from 70 to 20%, the grain yield GY also decreased. The highest GY was observed at the 70% light intensity level with the symbiosis of two fungi, resulting in a significant increase of 50.4% compared to the control level. It seems that fungal symbiosis partially compensated for the light-imposed reduction. Furthermore, when the average intensity for light declined from 100 to 70%, the harvest index (HI) initially increased by 0.7% and then decreased. By comparison, the activity of catalase (CAT) and glutathione peroxidase (GPX) enzymes increased with higher shade intensity. However, fungal symbiosis at different light levels decreased the activity of these enzymes.

In response to stressful conditions, plants undergo various physiological and biochemical modifications to enhance their resilience. Among these modifications, root exudates, comprising a diverse range of organic compounds, significantly impact plant resilience to drought and heat stresses. The soil microbiome plays a crucial role in mitigating drought and heat stress by enhancing plant resilience through various mechanisms, including nutrient acquisition, hormone production, and stress signal modulation. Its interaction with root exudates further amplifies these effects, as root exudates serve as key mediators in shaping microbial communities and promoting beneficial interactions. This review enunciates the crucial role of root exudates in conferring drought and heat stress tolerance, offering novel insights into the mechanisms, root structural changes, and physiological and biochemical adaptations. The role of microorganisms and their interaction with root exudates are explored to unveil the intricate network of interactions orchestrated by root exudates in stress adaptation, mitigation and resilience. In addition, this review examines the various physiological, abiotic, and biotic factors that impact the composition and dynamics of root exudates. Deciphering the complex interactions among these elements is essential to understanding the intricacies of plant stress responses. Furthermore, root exudate extraction techniques are briefed.
