<\/h5>\nDisease control is largely based on the use of chemical compounds toxic to plant invaders\u00a0and\u00a0pathogens. However, the hazardous effect of these chemicals on the environment and human health requires\u00a0to devise\u00a0new, safe\u00a0means of disease control.<\/p>\n
<\/h5>\nPlant defense activators\u00a0are\u00a0products\u00a0which act by triggering various physiological and morphological responses within the plant that result in\u00a0natural defense mechanisms.

Chitosan is a natural plant defense activator\u00a0derived from deacetylation of chitin, a compound readily available from shellfish waste from food processing. The chitosan molecule stimulates plant immunity against pathogens.<\/p>\n
Due to its antibacterial and antifugal properties, chitosan is successfully used in plant protection, as elicitor, growth promoter, enhancer of secondary metabolites production, and in soil correction. Application can be done by different ways : in the seed, in the soil or by foliar spraying.<\/p>\n
Chitosan induces\u00a0defense reaction in some plants, thereby increasing their responses against pathogens attack. Chitin and chitosan are used as elicitors for inducing phytoalexin accumulation in plant tissue\u00a0culture, phytoalexins produced act as toxins to the attacking organism.<\/p>\n
One of the most important bioactivity of chitin and chitosan on plants is stimulation\u00a0of seed germination. Chitosan coating\u00a0alters permeability of the seed plasma membrane, increasing not only the concentrations of sugars and proline,\u00a0but also enzymes activities.
