Gahrda Chitis

Gahrda Chitis is a special selected chitosan hydrochloride diverted from one special type of shrimp. Gahrda Chitis is globally the only chitosan produced from a single source of wild shrimp caught under the exclusive sustainable ecolabel of Marine Steward Council (MSC). The North Atlantic waters where these shrimps originate are the cleanest and purest waters globally and under strict protection surveillance.

Gahrda Chitis, which is our trade name for chitosan hydrochloride, is an abundant polycationic biopolymer. A nontoxic, fully biocompatible and biodegradable substance. Chitosan hydrochloride is applicable in multiple industrial and biotechnological applications. Predominant uses are biomedical applications, food preservative, packaging additive and wastewater treatment.

Gahrda Chitis is commercialized as Charge® by ADAMA - our official distributor for the European professional agricultural markets, as Sovelsa® by SYNGENTA - our official distributor for the European non-professional agricultural markets, and as KITO+® by AAKO - our official distributor for the Northern-African professional agricultural markets. These partnerships initially stemmed from the demand for sustainable pesticide alternatives in the sugar beet market. Charge®/Sovelsa®/Kito+®, as an elicitor, has now expanded its application to various crops in various countries, and has been thoroughly researched by many institutes and research stations, focused on sugar beets, cereals, grapevines, flowerbulbs and a range of other crops, as well as seeds.

The added value of Gahrda Chitis is that is constitues a lesser dependency on conventional chemistry and a higher disease control by preventive applications. As part of an ICM strategy it clearly demonstrates how elicitor efficacy can support the plant defense and improves the disease control.

Chitosan in agriculture

In agriculture Chitosan is typically used as a natural seed treatment and plant elicitor. An ecologically friendly substance that boosts the innate ability of plants to defend themselves against pathogenic infections. The natural biocontrol ability of Chitosan should not be confused with the effects of fertilizers or pesticides upon plants or the environment. Chitosan, as a basic substance*, is representing a new tier of cost-effective biological control for crops for agriculture and horticulture.

Mode of Action of Chitosan

Stimulation of Pentose Phosphate Pathway, causing positive morphological changes, by providing NADPH and sugar phosphates to:

• stimulate stronger rooting (increase rate of Shikimate Pathway, which can stimulate auxin production),
• stimulate more shooting (increase rate of purine and cytokinin production).

Increase phytochemical and phytoalexin production, causing positive biochemical changes:

• antioxidant response is stimulated, which improves Stress Response
• lignification (toughness of plant by stimulated lignin production)
• improved resistance against invaders, due to lignification and chitinase production.
