LATE AND EARLY FROSTS
Even if you have de-icing systems, it is, however, advisable to intervene on the plant to try to make it more responsive and resistant to the drop in temperature.
Each plant, as a living organism, is sensitive to frost to a greater or lesser extent depending on species and phenological stage. Within the same species, the phenological stage is the most important parameter. Flowering, in particular, is the stage at which plants are most sensitive to frost. Unfortunately, it is precisely at this stage that late frosts too often occur, which are responsible for reductions in yield and crop quality and the survival of the plants themselves. All living organisms, in nature, react to temperature drops by producing particular proteins, and amino acids, called antifreeze. Some plants, because of their genetic characteristics, can produce all or part of the antifreeze proteins and amino acids.
Therefore, one must be prepared to intervene in time and deal with the phenomenon effectively.
How to defend yourself
Late frost. In addition to normal cultural techniques to protect plants from frost, action can be taken a few days in advance of the event with CropAID AntiFROST (500 ml/hl). Plants after the application of CropAID AntiFROST will begin intense photosynthesis activity, and with this will also begin the production of rusticianin, oxaloacetic acid, pyruvic acid and numerous enzymes. Among these, rusticyanin is an enzyme belonging to the type of ferroxidases. When this enzyme is applied to plants, even in small amounts, it will immediately enter biochemical reactions and be directly or indirectly responsible for the production of new glucoproteins. Plants that can produce these proteins will have resistance to cold and frost. Plants will produce more antifreeze proteins (AFP) and more rapidly, which is why some of these valuable antifreeze substances are already contained in the product. Optimal efficacy occurs with repeated applications of CropAID AntiFROST started a few weeks in advance but treatment can be carried out up to 6-12 hours before the critical temperature is reached albeit with lower effectiveness. The treatment should be repeated throughout the frost period on at least a weekly basis, and if temperatures have risen again, it is advisable to continue with the treatments, so that at least three treatments are made on a fortnightly basis to get the stress suffered by the plant over quickly. The product also has a nutritional and biostimulating action on growth. To complete the protection from cold and for a more prompt recovery of the plant from stress, particularly on fruit plants (pome and stone fruit in primis) we recommend the additional use of Auxiger LG (0.5-0.7 L/ha) +
Alga Mix B Mg (3 L/ha) the day before the peak was reached, followed by a treatment, immediately after and within 24 hours after the frost, with Auxiger LG (0.5-0.7 L/ha) + Gibrelin (1 L/ha) + Alga Mix B Mg(3 L/ha) to restore hormone balance altered by heat stress. Auxiger LG accelerates the energy metabolism of the plant, which accumulates more solutes in the cell juice increasing its resistance to temperature changes and providing it with the necessary energy to recover from the shock. In the case of early autumn frosts, the use of.
CropAID AntiFROST (500 ml/hl) followed by the use of Seaweed Mix B Mg (3 L/ha) or of the new product EnerGemma (2 kg/ha) formulation rich in Boron and Zinc, which contributes to the nutrition of fruit buds in autumn.
