Fortress enhances tolerance to extreme temperatures and helps prevent water stress, infilteration by fungal pathogens and sap sucking pests. Fortress is helpful in reducing the effects of toxic iron and manganese levels. Fortress can be used for foliar applications at recommended dose. We recommend foliar application at the rate of 5 ml per liter (500 ml in 100 to 160 litres of water per acre). Fortress is not compatible with any foliar fertilizers or pesticides and should not be applied in combination with other foliar products.
