Reliable crop protection: Working with Merpan WG

When it comes to contact fungicides, understanding how a product performs in real-world conditions is key. Merpan WG from ADAMA is a classic solution for apple orchards and legumes, proven to withstand challenging weather. Its main advantage is reliability: the active ingredient, captan (from the phthalimide class), creates a protective barrier on the surface of leaves and fruit, preventing fungal spores from penetrating the plant tissue.

Operational features

For an agronomist, working with water-dispersible granules is all about convenience. The granules dissolve quickly in the sprayer tank, generate no dust, and do not clog nozzles—a critical factor during high-volume operations.

• Efficacy against scab and rot: On apple trees, this product is a top-tier tool. Preventive application keeps scab under control, provided the treatment schedule is strictly followed.
• Application flexibility: The dosage range of 1.9–2.5 kg/ha allows for precise adjustment of protection intensity based on the actual disease pressure.
• Contact action: It is crucial to remember that this is not a systemic fungicide; coverage quality accounts for 90% of the success. Ensure thorough application to hit every surface.

Practical advice

In crops like soybeans and peas, Merpan WG effectively suppresses the development of anthracnose and ascochytosis. The maximum allowed number of applications is 3 times per season. Since the product is classified as Hazard Class 2, wearing personal protective equipment while mixing is non-negotiable. Even though it is a contact-only product, it remains a powerful tool in the arsenal of any professional agronomist who knows how to build a smart crop protection strategy.
