13 12 H2O Ca EDTA Ca L-Asp Risks in foliar application Leaf cuticle thickness varies by crop, affecting phytotoxicity risk. Agronomic experience is vital and small trials are recommended for increasing rates (0.1-3% for Poly-Feed, <0.1pc for micronutrients). Thinner cuticles in humid conditions elevate the phytotoxicity risk. Caution is needed with high EC levels. Small-area trials are advisable when implementing new foliar programs, as well as testing compatibility before application using a bucket mix test. You should be careful with other elements like copper, sulphur from fungicides, or additional micronutrients, as there can be a higher risk of phytotoxicity. Foliar applications with Haifa Calmaster Cell strength: Calcium enhances cell structure, allowing potassium to improve crop size, crunch and storage benefits. This increases resilience to pests and disease, and, in poor weather conditions, it helps prevent creasing, cracking and other damage to produce. Weather impacts: Poor transpiration or root uptake conditions can limit calcium uptake, leading to issues like blossom end rot or tip burn on young growth. Addressing deficiencies: Foliar calcium helps combat deficiencies caused by high urea or ammonium levels, which can hinder root calcium absorption or promote rapid vegetative growth. Nutritional coverage: During peak growth or adverse weather or soil conditions, foliar applications can ensure plants receive essential calcium otherwise unavailable due to inefficient soil uptake or plant allocations. Calmaster benefits Enhanced Calcium Uptake: Calmaster improves foliar calcium absorption and is compatible with sulphate and phosphate, reducing costly crop passes and improving tank-mix efficiency. High uptake effectiveness: Calmaster is coated with aspartic acid chelate for better penetration through leaf cuticles and its low molecular weight ensures maximum benefit from smaller application rates, with no harmful additives. Optimal application timing: The best uptake of Calmaster occurs during evening dew. To maximise effectiveness, Haifa incorporates a wetter in Poly-Feed and Haifa Bonus to allow for application any time of the day, so ideally, combining Calmaster with Haifa Poly-Feed or Bonus will offer full nutrition with added efficiencies. Wall-Up Wall-Up contains 8.5pc silicon, 0.8pc copper, 0.8pc manganese and 1.1pc zinc. Ideal for foliar applications, it enhances plant resilience against pests and disease by improving cell wall strength. Silicon forms phytoliths that boost the mechanical resistance of plant tissues. Application summary for foliar solutions Haifa Bonus combined with Calmaster and Wall-Up is ideal at key fruit development stages to improve yield, leaf performance, product quality and shelf life. Poly-Feed Foliar, combined with Calmaster and Wall-Up at vegetative growth stages, provides NPK and micronutrients combined with additional copper and manganese to ensure plant strength and resilience to pests and disease. The success of a grower is not only growing successfully in good weather, but also growing in bad weather and soil conditions. Combined, these products cover the bases using targeted foliar applications and with ideal tank compatibility to help limit crop passes. The Bonus wetter in Haifa’s foliar range, if used in combination with Calmaster and Wall-Up products, provides a solution, effectively holding product on the leaf and ensuring ongoing uptake over many nights of dewpoint.
