Protecting Solanaceous Crops from Fungal Stress

When battling blight (phytophthora) or alternaria, you need a solution that works fast and lasts. «Junker w.p.» from the Polish manufacturer «Хімічні заводи «Органіка-Сажина»S.A.» has become a reliable staple in our crop protection program. It effectively combines systemic and contact actions, providing a robust shield for our tomatoes, potatoes, and grapevines.

Dual-Action Mechanics

The core of this fungicide is the synergy between mancozeb and metalaxyl. Metalaxyl acts systemically, moving through the plant to reach new growth and stopping infections from the inside. Meanwhile, mancozeb acts as a contact barrier, ensuring that fungal spores cannot establish a foothold on the leaf surface. This is particularly effective for controlling downy mildew in vineyards, where rapid prevention is key to a healthy harvest.

Operational Insights

• Preparation: As a wettable powder, it requires proper mixing. We recommend preparing a slurry first to ensure a smooth, homogeneous solution before adding it to the main spray tank. Continuous agitation is recommended.
• Application Timing: We limit usage to three treatments per season, strictly adhering to the 14–20 day pre-harvest interval to ensure product safety.
• Handling: Rated as Class 3 hazard, it fits into standard safety protocols—respirators and gloves are a must, as with any high-quality chemical agent.

For us, «Junker» represents the high standard of Polish chemical manufacturing. It delivers consistent protection against a wide range of pathogens without causing phytotoxicity, making it an essential part of the seasonal rotation for any commercial grower.
