The arrival of winter brings with it one of the biggest challenges for farmers: frost. These weather events can cause significant damage to crops, affecting both the quantity and quality of the harvest. COMPO EXPERTWe understand the importance of protecting your crops and minimising the impact of stress caused by low temperatures. That is why we offer you two specialised products that will help you cope with frost: Basfoliar® OsmoProtect SL and Basfoliar® Stark SL.
Impact of Frost on Crops
Frost can cause ice crystals to form in plant tissues, resulting in irreversible cell damage. In addition, low temperatures can disrupt the process of photosynthesis and other essential metabolic mechanisms, weakening the plant and reducing its capacity for growth and production.

Basfoliar® OsmoProtect SL: Active Protection in Cold Periods
Application:

- Shape: Foliar application (2L/ha) or via irrigation (5L/ha).
Benefits: Basfoliar® OsmoProtect SL is a concentrated defense stimulant that helps plants withstand adverse winter conditions. By applying this product, the plants' resistance to cold is improved, helping them maintain their vigor and health during critical periods.
Basfoliar® Stark SL: Stimulation of plant defense metabolism
