Soil fungi are vital members of the soil ecosystem, performing a multitude of functions critical for ecosystem health. This study examined the relationship between soil properties and fungal communities in Tunisian agroecosystems. Soil characteristics like pH, electrical conductivity, bulk density, and nutrient content displayed significant variations across the studied crops. These variations suggest the need for tailored irrigation and fertilization practices for optimal plant growth. Fungal abundance also varied significantly, with pomegranate (P. granatum cv. Gabsi: 14.82 x 10⁵ CFU/g of soil) harboring the most abundant community, while tomato (S. lycopersicum cvs. Firenze and Dorra: 0.92 x 10⁵ and 0.66 x 10⁵ CFU/g of soil, respectively) exhibited the least. Similarly, Trichoderma spp. abundance followed the same pattern (2.02 x 10⁵, 0.04 x 10⁵, and 0.06 x 10⁵ CFU/g of soil, respectively). Analysis revealed that fungal abundance increased in soils with low salinity, compaction, and clay content, but increased more in environments rich in organic matter, nutrients, and well-drained sandy textures. Furthermore, a preference for a higher soil carbon-to-nitrogen ratio suggests fungi favor readily available carbon sources for growth. In Tunisian agroecosystems, soil properties significantly influenced fungal abundance and composition across crops. This highlights the need for tailored management practices to promote both plant growth and beneficial fungi, with a focus on maintaining good soil health for diverse fungal communities.

“…The rapidity with which the disease spreads makes it very difficult to follow only chemical control (Liu et al 2016) which has many risks including hazardous effects on human and animal health, effects on nontarget organisms, the entrance of residual toxic compounds in the food chain and effects on microorganism biodiversity (Rhouma et al 2021e;Hajji-Hedfi et al 2022;Hajji-Hedfi et al 2023). Therefore, the researchers developed many programs to control plant diseases by using eco-friendly biopesticides which contain biological control agents like arbuscular mycorrhiza, endophytic fungi (Trichoderma spp., Chaetomium spp., Gliocladium spp., Paecilomyces spp., Acremonium spp., Beauveria spp., etc.)…”

Wheat (Triticum aestivum L.), which belongs to the order Poales and Family Poaceae, is one of the most important strategic cereal crops around the world. There are many fungal diseases that may occur with this crop. Ascochyta leaf spot is one of the important foliar diseases of wheat. It was found that Ascochyta tritici (Teleomorph: Didymellaexitialis) among many pathogens, is the main causal agent of this disease. The disease becomes severe when the weather is rainy and high humidity conditions. The disease symptoms were represented by occurring oval spots, sometimes elongated, light-colored, and surrounded by a brown margin, then generated white necroses with a very dark brown-black border. Sometimes, symptoms are like those caused by Septoria nodorum. Symptoms are often seen on lower leaves early in the season and on upper leaves later on, so they become less distinct with time, appearing very similar to those caused by S. nodorum. The disease can be controlled by using healthy seeds treated with fungicides, applying crop rotation, conventional tillage, good aeration between plants, balanced fertilization, using plant extracts, and applying many foliar fungicides. Moreover, different bioagents including Trichoderma spp., Pseudomonas fluorescens, and Bacillus spp. have been used to control Ascochyta leaf spot disease biologically and reduce the disease severity significantly. This review summarizes the current knowledge of symptoms and signs, epidemiology, ecology, disease development, disease cycle, and disease management.
