Arthrospira platensis

Arthrospira platensis, commonly known as a type of spirulina, is frequently misclassified in agricultural databases as a plant disease. In reality, it is a genus of photosynthetic cyanobacteria that plays a positive role in soil health and crop productivity rather than acting as a pathogen.

From an agronomic perspective, this organism acts as a bio-stimulant. It contains essential amino acids, proteins, and vitamins that support the healthy development of various crops when used as a foliar spray or a soil additive. It does not possess any mechanisms to infect or damage plant tissues.

The development of these organisms requires specific aquatic or semi-aquatic environments with high pH, intensive light exposure, and temperatures between 25°C and 35°C. These growth requirements ensure that it does not become an invasive species or an unwanted pest in traditional soil farming.

There is no pathogenicity associated with this species. Its presence in agricultural systems is highly beneficial, as it promotes nutrient cycling and enhances the microbial activity within the soil rhizosphere, which in turn leads to improved plant resilience against environmental stress.

Prevention or eradication measures are unnecessary as this organism is considered a beneficial input in sustainable farming. Agronomists recommend focusing on organic soil management to foster healthy microbial communities, which naturally include various species of microalgae and cyanobacteria.
