It acts as a broad-spectrum fungicide and insecticide/acaricide: on plants, it controls powdery mildew, monilia, and San Jose scale when applied during winter dormancy; on animals, it helps control scabies and other external mites thanks to its sulfur-based action. It has a cumulative effect after several applications and provides good persistence if it does not rain after treatment.

Application

Preventive Curative

Pathology : Powdery mildew (Fungus) Brown rot (Monilinia) (Fungus) San José scale (Other) Mange / mites (scabies) (Other)

Application description : Aplicar en pulverización foliar en las horas de menor calor (atardecer), evitando el sol directo y temperaturas superiores a 28-30 °C (riesgo de fitotoxicidad). Usar equipo de protección completo durante la preparación y la aplicación (producto cáustico). Repetir cada 10-15 días según presión de la plaga o enfermedad, respetando el plazo de seguridad antes de cosecha.

Tips

Apply preferably in the winter, when the tree is dormant (leafless), to prevent leaf burn—never during flowering or in high temperatures. Dilute before use (typically 1 part concentrate to 10–20 parts water, depending on the crop) and apply during the coolest hours of the day. For use on livestock (baths or lotions for scabies), dilute to a higher ratio and always test on a small area of skin before treating the entire animal—avoid contact with eyes and mucous membranes. Always wear gloves, goggles, and a mask when handling it, due to its strong odor and concentrated corrosive nature.

Preparation process

In a heat-resistant pot, combine 2 kg of powdered sulfur and 1 kg of quicklime for every 10 liters of water. First, add a little water to the quicklime to slake it, then gradually stir in the sulfur, stirring constantly to prevent lumps from forming. Add the remaining water and bring to a boil, then simmer for 45 to 60 minutes over medium heat, stirring every few minutes, until the mixture takes on a characteristic reddish-orange color. Let it cool and sit overnight—the next day, decant the clear liquid (the sulfocalcic solution itself) by separating it from the sediment at the bottom. Filter it through a strainer or cheesecloth before transferring it to a dark or opaque glass container with a tight-fitting lid.

Product obtained

A reddish-orange to dark brown liquid with a strong, pungent odor (sulfur/rotten eggs) and a slightly cloudy texture. It keeps well in a sealed container protected from light, although sediment may form over time—shake well before use.
