  Plant Health Care, Inc. initiates large scale grower tests for a ProActTM +
                               Glyphosate product


Plant Heath Care, (AIM: PHC.L), a leading provider of natural products for
plants and soil, has initiated a large scale field trial program for corn,
soybeans, and cotton to further evaluate the already established benefits of
using ProActTM in combination with glyphosate, the world's most commonly used
herbicide, when applied over-the-top of glyphosate resistant crops. Five years
of independent testing have demonstrated significant yield increases in cotton
and corn when treated with a combination of ProAct and glyphosate. ProAct is a
foliar spray product for reducing nematode populations and improving overall
plant health. ProAct, which is the only foliar spray product labeled for use
against nematodes in corn and soybeans, contains Harpin, a second generation
harpin protein formulated as a wettable dry granule.


PHC Director of Field Biology Ned French says, 'ProAct increases yields. The
comprehensive data from multi-year ProAct research shows average increases of
2.5 bushels/acre in soybeans, 7 bushels/acre in corn, and 68 pounds of cotton
lint/acre. These yield increases translate into economic returns of $28, $35,
and $50/acre, respectively. The ProAct + Glyphosate Program will help both
groups learn more about the benefits in real-world farming conditions.'

All participants will be asked to join a series of post-harvest teleconferences
to discuss how the ProAct + glyphosate tank-mix performed on their farms. PHC
will use the information gleaned from the teleconferences as the basis for
better understanding farmer needs and perceptions as they relate to the use of
ProAct + glyphosate.


PHC, started in 1995, was originally focused on horticulture, turf, vegetables
and high value crops. The company started targeting field crops -corn, soybeans,
and cotton - in 2007 based on its acquisition of harpin protein technology
products such as ProAct. ProAct contains the most recently developed and
effective generation of harpin proteins.
