Storage
Our products are tested between -10 °C and + 45°C and can be stored within this temperature-range. Occurring crystals due to cold storage will dissolve again at higher temperatures. We recommend a frost-free storage and a product-temperature above +5 °C at the time of use.
Miscibility
Lebosol®-PK-Max is compatible with all commonly used plant protection products. Since not all the influences appearing in practice are predictable, a miscibility test with small amounts of the products provided for the spraying is always useful. Don’t mix with fertilizers containing calcium or magnesium and with manganese nitrate. In case of mixture with fertilizers or plant protection products fill sprayer up to 2/3 with water and add products separately. Add Lebosol®-PK-Max as the last component.
Product active agent
Phosphorus availability is low on acidic or very alkaline (calcareaus) soils, soils with low organic matter or in iron rich soils and in cold and wet conditions. Phosphorus deficiency often appears in crops with a poorly developed root system.
Phosphorus deficiency is shown by fewer and smaller tubers in potatoes, small, dark green younger leaves, stunted plants, red colouration on stems and leaves, lower fruit quality and reduced storage potential.
