♦ Prevents physiological disorders

♦ Enhances stress resistance

♦ Extends fruit shelf life

HaifaStim™ Calmaster is an advanced calcium formulation that allows fast absorption of calcium by plants, and its assimilation in plant tissues, thus preventing physiological disorders related to calcium deficiency.
HaifaStim™ Calmaster provides plants with calcium in the form of L-Aspartic Acid chelates. Due to its low molecular weight, this chelating agent enables efficient penetration of the calcium through leaf cuticle, facilitating its uptake and activity. The unique chelating technology prevents calcium from blocking, fixation and precipitation with other nutrients or agrochemicals. It also ensures stability in a wide pH range.
HaifaStim™ Calmaster PluS combines the benefits of calcium as L-Aspartic Acid chelate and silicon as ortho-silicic acid. The synergic activity of calcium and silicon supports strength of cell membranes and plant skeleton.

Fast, highly efficient absorption of calcium from HaifaStim™ Calmaster or Calmaster PluS helps preventing typical disorders related to calcium deficiency:
♦ Blossom end rot (BER) in tomato, pepper and other susceptible crops
♦ Bitter pit in pomme fruits
♦ Cracking in cherries, plums and other stone fruits
♦ Sun burns in fruits and green vegetables
♦ Secondary infections due to wounds

HaifaStim™ Calmaster and Calmaster PluS are fully soluble in water and ideal for application by foliar sprays and Nutrigation™.

Applications

It is advised to apply HaifaStim™ Calmaster or Calmaster PluS from fruit setting, through fruit development until harvest.
In alkaline soils, where calcium fixation and calcium carbonate formation take place, it is highly recommended to supplement plant nutrition with HaifaStim™ Calmaster or Calmaster PluS.
Compatibility: HaifaStim™ Calmaster and HaifaStim™ Calmaster Plus are compatible with most fertilizers and agrochemicals.
It is recommended to carry out a small-scale test before preparing a tank-mix.
