Grinfort Dok

Chemical Profile and Mechanism

Grinfort Dok is a systemic fungicide formulated with tebuconazole, a potent triazole compound. Its technical architecture is built for rapid uptake through vegetative plant parts, followed by acropetal translocation throughout the plant system. This movement ensures that both existing foliage and new, developing tissues receive active protection against pathogen colonization. The emulsifiable concentrate formulation enhances surface adhesion, ensuring consistent distribution of the active ingredient across the leaf cuticle.

Efficacy Against Pathogens

The fungicide acts by inhibiting the demethylation of ergosterol, a critical component of fungal cell membranes. By arresting the synthesis of this sterol, Grinfort Dok effectively stops fungal growth and reproduction. This makes it a powerful tool against a broad spectrum of diseases, including:

• Cereal pathogens: Helminthosporium, Septoria, Fusarium head blight, and various rusts (yellow, brown, stem).
• Barley diseases: Specifically net blotch (Pyrenophora teres).
• Broad-spectrum control: Highly effective against powdery mildew on winter crops.

Operational Guidelines

With an application rate ranging from 0.5 to 1.0 L/ha, Grinfort Dok allows for precise adjustments based on current disease pressure. It is labeled for up to two applications per season, providing flexibility in integrated pest management (IPM) programs. As a Class 3 hazard level product, it balances high potency with safety, provided the 30-day pre-harvest interval (PHI) is strictly observed.

The product, manufactured through the partnership of TRUSTCHEM and AgroMaxi, demonstrates high compatibility with other agrochemicals, making it a reliable component in standard tank mixes for winter wheat, winter barley, rye, and winter rapeseed protection protocols. Its systemic nature ensures that once absorbed, the active ingredient provides lasting residual protection, securing crop potential against environmental and biotic stressors.
