Amorphotheca resinae

Amorphotheca resinae is a specialized microscopic fungus widely known as the "kerosene fungus." While it does not infect crops directly, it is a significant concern in the agricultural sector due to its destructive impact on fuel storage systems, equipment, and fuel-delivery infrastructure.

The pathogen is an ascomycete fungus that exhibits a unique ability to utilize hydrocarbons as its primary carbon and energy source. It thrives in aviation fuels, diesel, and other petroleum products, making it a major challenge for the maintenance of heavy agricultural machinery.

Symptoms of infestation include the formation of thick, slimy, mat-like fungal colonies inside fuel tanks, pipelines, and filters. These growths often appear as dark, filamentous structures that can completely clog mechanical fuel systems, leading to engine stalls and operational failures.

Development and spread of the fungus are strictly dependent on the presence of water within the fuel supply. Even small amounts of condensed water at the bottom of a storage tank provide the necessary interface for the fungus to germinate and proliferate, consuming the hydrocarbons in the fuel above.

The damage caused by Amorphotheca resinae includes severe microbially induced corrosion of metal components and the degradation of fuel quality. This results in costly repairs to injectors and pumps, decreased machine efficiency, and significant downtime during critical agricultural seasons.

• Maintain low water levels in fuel storage tanks.
• Use biocidal fuel additives to inhibit fungal growth.
• Regularly replace fuel filters and inspect tanks for deposits.
• Ensure proper storage conditions to prevent condensation.
