GLU-CaB is a nutrient with Calcium and Boron that together with Gluconate forms a complex that provides a balanced supply of components. This improves the assimilation of each one, corrects shortages of components and prevents malformation and fall of young fruits and necrosis at the edges of leaves (for example, in “bitter pit” or “corked” leaf vegetables in apple and pear trees, apical decay in different vegetables, and rotting of fruits in general).
The application of GLU-CaB enhances the cell walls of the vegetable and increases the plant’s resistance to various adverse factors, biotic and abiotic.
In addition to its structural functions, calcium is a growth-stimulating factor for the root’s hair and for the root itself.
In plants, calcium is present in the leaves, stems/plumules and root. The amount contained in the seed is less significant.
Most of the calcium that is absorbed by plants is found in cell walls. It has been shown that it stimulates the response of cells or protoplasm to products produced by microbes (elicitors).
The amounts of many plant pathogens were verifiably reduced following applications of calcium. Some examples include grapevine “oidium” (Uncinula necátor), coffee “cock’s eye” (Mycena citricolor), and Sclerotium rolfsii in carrots. The same effect has also been verified in several species of Pythium of different crops.
When calcium was applied, a reduction in the intensity of Phytophtora cinnamoni in avocados and Phytophtora nicotiana in citrus was also observed.
Boron has a structural function in the cell wall of plants associated with the formation of pectin. It is a critical element used to suppress pathogens in plants. To date, the mechanism of its suppressive action is only partially known. We have several examples of its pathogen suppression: Xanthomonaspestris pv.campestris in cauliflower, Plasmodiophora brassicae in the brassica species, Fusarium oxisporum f.sp.lycopersici in tomatoes, “Yellow rust” in wheat, (Puccinia striiformis), and more.
It is presumed that in addition to its structural action, at its proper concentration it is toxic to some pathogens.
The combination of calcium and boron provides structural constitutive strength, and is essential in the mechanisms of defense against abiotic and biotic adversities.
