Acaulosporaceae

It is important to clarify that Acaulosporaceae is not a plant disease. These organisms are actually arbuscular mycorrhizal fungi (AMF). In agronomy, they are classified as beneficial soil symbionts that establish a crucial relationship with plant roots, rather than as pathogens causing diseases.

The biological nature of these fungi involves forming specialized structures called arbuscules within root cortical cells. These structures do not cause damage; instead, they facilitate the efficient exchange of phosphorus, nitrogen, and water from the soil to the plant in exchange for plant-produced carbohydrates.

Acaulosporaceae colonize the roots of the vast majority of agricultural crops, including wheat, maize, legumes, and many horticultural varieties. By extending the surface area of the root system, these fungi significantly enhance the plant's ability to survive in nutrient-poor soils and resist drought stress.

The conditions for the development of these fungi include healthy soil structure, limited soil disturbance, and the presence of living host plants. They thrive in environments where excessive chemical interventions, such as heavy fungicide use, are minimized, as these chemicals can disrupt the symbiotic network.

Rather than seeking methods to eradicate this fungus, modern agriculture focuses on conservation and management strategies to promote mycorrhizal colonization:

• Implementing no-till or reduced tillage practices.
• Using cover crops to maintain living roots.
• Avoiding high doses of phosphate fertilizers that suppress symbiosis.
• Applying bio-inoculants containing compatible AMF strains.
