activadores de defensas

Chitosan is characterized by protecting crops against attacks by pathogens and pests, directly or indirectly, such as improving the quality of the crop, or maintaining the stability of production during storage after harvest.

Chitosan is an elicitor that activates the self-defense capacity of the plant. Pathogens enter plants through three mechanisms: By their own means, through wounds, and through natural openings (including stomata).

Stomatal openings in plants provide an entry way for many pathogens, reducing these openings can provide an effective method to prevent attack by pathogens that have chitin as a component of their cell wall.

The products of the BOCROP QUITOSANE line activate mechanisms in the plant that order the closure of stomata. The application of chitosan causes a false stress in the plant, since it confuses the presence of the product with the proximity of a pathogen ready to attack it. This recognition sets in motion a complex self-defense mechanism, partly based on the role that calcium plays as a second messenger.

The products of the BOCROP QUITOSANE line allow the entry of Calcium into the cell, as an important element in the activation of defenses in cultures. The calcium that penetrates the cells, favors the strengthening of the cell membranes, which allows the maintenance of the turgor and the firmness of the fruits in post-harvest.

In addition, the products of the BOCROP QUITOSANE line also activate the formation of physical barriers, activate the formation of secondary roots and root hairs in the adult plant, activate the adsorption of micronutrients, etc ...

It should also be noted that the products of the BOCROP QUITOSANE line are used for coating seeds, for their preservation during storage and in the release of fertilizer systems.
