Hamerol is a biological plant strengthener based on chitosan hydrochloride. The product supports the natural resilience of crops against pathogenic fungi, harmful nematodes and drought stress. This makes Hamerol a valuable addition to sustainable and integrated crop protection for conventional, organic and PlanetProof cultivation.
Hamerol can be used preventively to make plants more resilient both above and below ground. The product fits into cultivation schedules where growers are looking for biological crop protection and want to become less dependent on chemical crop protection products.
This plant strengthener is useful in situations involving pressure from fungi and nematodes, limited root development or periods of drought stress. Hamerol can also help partially fill gaps that have emerged in existing crop protection schedules.
Chitosan hydrochloride is derived from chitin, a natural biopolymer found in fungi, insects and crustaceans, among other sources. Plants recognise this substance and respond by activating their natural defence mechanisms.
Chitosan also influences the microbial community in the soil. Beneficial bacteria and mycorrhiza-forming fungi are supported, making nutrients more available and creating a stronger, biologically active environment around the roots.
Hamerol is diluted with clean tap water and applied using a clean spraying system. The product is easy to integrate into integrated crop protection, but mixing it with other crop protection products is not recommended.
Plant Power Products has been following international research into chitin and chitosan hydrochloride for decades. In addition, Hamerol is tested in trial and demonstration fields with growers and official research institutes in the Netherlands and abroad.
A plant strengthener is not a standalone miracle solution, but part of a resilient cultivation system. Hamerol can be combined with monitoring, soil management and targeted interventions to reduce dependence on chemical crop protection products.
