Cerexil

Reliable protection for potatoes and tomatoes against a range of diseases

When late blight or alternaria hits your field, there is no time for trial and error. Cerexil from UPL is a robust tool for any agronomist, combining systemic and contact action. By utilizing a blend of mancozeb and metalaxyl, the product acts in two ways: it eliminates spores on the leaf surface and blocks mycelial development within the plant tissue.

Field Application Experience

Field practice proves that at a dosage of 2–2.5 L/ha, the product provides stable protection even under adverse weather conditions. Importantly, Cerexil features strong curative properties; if you spot initial infection sites, the systemic metalaxyl component quickly interferes with the fungus's metabolism, halting the spread. In vineyards, where downy mildew can destroy a harvest in a week, the ability to apply up to 3 treatments per season offers flexibility during the crop's critical growth stages.

Operational Insights

• Systemic & Contact Action: Mancozeb builds a protective barrier, while phenylamides (metalaxyl) ensure deep penetration into young shoots.
• Usage Protocol: Limit to 3 treatments per season. Observe the 14-day pre-harvest interval to ensure residue-free crops.
• Safety: The product is classified as hazard class 3. Despite its moderate toxicity, proper PPE usage during sprayer preparation is non-negotiable.

The UPL Vietnam production facility ensures consistent formulation quality, which is crucial for modern nozzle performance—the emulsion flows easily without clogging filters and spreads evenly across leaf surfaces. With proper tank-mix preparation, Cerexil becomes a cornerstone of any fungicide strategy for tomatoes and potatoes, allowing you to focus on other farm management priorities.
