LeCar BT

Systemic Protection: The Chemistry of Tebuconazole

The fungicide 'Лекарь Бт' (Lekar Bt) by 'Інфорс Хемікел' is powered by tebuconazole, a member of the triazole family. Its primary technical advantage is systemic activity: upon application to winter rapeseed, the active ingredient is quickly absorbed into the plant tissues and moves acropetally (upward). This is vital for protecting new growth that develops post-treatment, ensuring long-lasting defense.

Engineered for Rapeseed Pathogen Control

Formulated as a suspension concentrate, the product ensures superior adhesion to the waxy leaf cuticle and rapid penetration. 'Лекарь Бт' targets major pathogens that can reduce yield potential by up to 50% under epiphytotic conditions:

• Alternaria: inhibits spore germination and mycelial growth, preventing pod spotting.
• Phoma leaf spot: halts infection entry through micro-lesions in stems.
• Cylindrosporium: effectively blocks mycelial development during periods of high humidity.

Application Strategy and Dosage

For optimal biological efficacy, the recommended application rate is between 0.5 and 1.0 liters per hectare. The protocol allows for a maximum of two applications per season, providing flexibility in management: an initial preventive treatment followed by a curative application if disease symptoms appear or during active stem elongation phases.

Classified as a Hazard Class 3 substance, the fungicide requires standard safety protocols during handling and application. Thanks to its systemic mode of action, 'Лекарь Бт' provides robust control even if the initial infection window is missed, establishing itself as a reliable tool for intensive winter rapeseed production.
