Protecting Sunflower Crops: Field Experience with Tetris Fungicide

When dealing with sunflower pathology, timing and efficacy are everything. In my experience, using the Tetris fungicide from Pest.Ua has proven to be a reliable way to manage fungal risks. This systemic product stands out not just by its chemical name, but by how it behaves in the tank and on the leaf.

Why Nanoemulsion Matters

The formulation of Tetris as a nanoemulsion concentrate is a major plus for any field operator. It ensures a highly stable mixture, meaning you don’t have to worry about sedimentation or uneven application. Pyraclostrobin, as a strobilurin active ingredient, requires excellent coverage to be effective, and this formulation allows the product to spread across the leaf surface seamlessly, providing immediate systemic absorption.

Application and Dosage

• Targets: Tetris is highly effective against Alternaria, Septoria, Phomopsis, and Phoma.
• Application Rate: The recommended dose is 0.5–1.0 L/ha. In my practice, I adjust the rate depending on the stage of the infection: for preventative measures, 0.5 L/ha is sufficient; for established infections, I step up to 0.8–1.0 L/ha.
• Limit: The product is labeled for a maximum of 2 applications per season to prevent pathogen resistance.

Field Handling

From an operational standpoint, the product is easy to handle. Classified as Class 3 for safety, it follows standard handling protocols, which any professional crew is already familiar with. Its systemic action ensures that even new growth is protected, which is essential for sunflower development during high-stress periods. I have mixed it with various adjuvants without issues, though a jar test is always a good practice before scaling up.

For those looking to keep their sunflower canopy clean and functioning until the very end of the cycle, Tetris offers the consistency needed for high yields. It is a predictable, easy-to-use tool that does exactly what it says on the label.
