CeraSulfur A New Approach to Sulphur-Based Crop Protection

CeraSulfur® is a liquid fungicide and insecticide based on bio-sulphur, offering a more effective and practical product compared to conventional sulphur-based products. Its active ingredient is produced through a biological process in which specialised microorganisms convert hydrogen sulphide (H₂S)—a toxic gas generated as a by-product of industrial processes such as wastewater treatment and bioethanol production—into elemental sulphur. The recovered sulphur is then used to produce bio-sulphur with an exceptionally fine particle size and hydrophilic properties, contributing to the product’s unique characteristics. These characteristics contribute to its efficacy and may allow for reduced application rates, depending on the crop, target pest or disease, and field conditions.

Designed for foliar application, CeraSulfur® protects against fungal diseases and helps manage pest mites. It can be incorporated into conventional crop protection programmes and integrated pest management (IPM) systems. Its formulation offers high efficacy and resistance to wash-off, helping maintain performance under suitable field conditions. Elemental sulphur has a multi-site mode of action, resulting in a low risk of resistance development in fungal pathogens.

Koppert has successfully integrated CeraSulfur® into citrus IPM programmes for mite management in combination with Spical (Neoseiulus californicus), as well as for powdery mildew management in ornamental, vegetable and grape crops.

By combining a unique hydrophilic nature with a small particle size, CeraSulfur® offers effective disease protection and mite control at potentially lower application rates. Together with its low toxicity and limited environmental impact, these characteristics make it a valuable tool in integrated pest management programmes.
