RESEARCH - NEMATODES

Rothamsted Experimental Station research has confirmed that Maxicrop Seaweed Extract inhibits the hatch of a range of certain nematode species:

	Globodera rostochiensis (Potato Cyst Nematode)
	Globodera pallida (PCN)
	Heterodera schachtii (BCN)
	Meloidogyne incognita (Root Knot Nematode)
	This inhibition is reversible when the seaweed extract is removed from the system, except for H schachtii.

Plant Root Diffusate (PRD)

	Definition - specific nematodes can identify and find their host by identifying the diffusate, which is specific to that host - in this case potato. It is also a potent stimulator of nematode egg hatch (i.e. the eggs 'know' to hatch when roots of their host are in the vicinity)
	Rothamsted confirm that the hatching J2 nematodes are disorientated and slower moving when in continuous exposure to Maxicrop.
	Nematode downward movement also slows. This means that they are less able to migrate to root tips and unable to penetrate the roots.
	Those J2 nematodes that do reach the roots produce a lower number of cysts or galls and fewer eggs per gall or cyst.
