Huwa-San TR-50: securing the coffee culture

Horticulture Guatemala
Coffee leaf rust is considered to be one of the most destructive diseases in the coffee industry and is caused by the leaf rust devil, the fungus Hemileia vastatrix. A coffee grower contacted Roam Technology since his plantation was heavily affected by the fungus, resulting in reduced production and quality.

The challenge

As coffee rust is a foliar disease, infections are diagnosed by premature leaf fall and orange irregular shaped spots on the upper leaves. At the bottom leaves orange powdery lesions can be observed, which contain the spores that will be transmitted to initiate a new infection cycle. If no preventive measures are taken, infected leaves will drop, which might result in tree death in severe occasions. Therefore, Huwa-San TR-50 was used as a biocide to prevent thriving of this fungus, and also to guarantee healthy trees and coffee beans.

Our solution

Roam Technology advised to spray the coffee trees every 14 days with Huwa-San TR-50. After one season of repeated exposure to Huwa-San TR-50, a dramatic drop in rust was observed as almost none of the leaves displayed symptoms of coffee rust.

The results

The best way to obtain healthy coffee trees, and thus top quality coffee beans, is to spray with Huwa-San TR-50 biweekly to prevent the burst of Hemileia vastatrix. This way, yield is secured without compromising the environment.

  • High standard coffee beans production
  • Environmentally friendly product that leaves no residue
  • Improved plant health
