       Myconate - 2006 Trial Results continue to impress around the world


Plant Health Care (AIM: PHC.L), a leading provider of natural products for
plants and soil, is pleased to report the early success of its Myconate test
programme in 2006. Building upon the impressive results from prior years, the
results of this year's trials to date further validate the effectiveness of
Myconate in increasing yields of many different crops all over the world.


PHC's novel Myconate technology helps crops to develop larger root mass by
triggering the colonisation of beneficial micro-organisms called mycorrhizal
fungi.  With more mycorrhizal fungi at work, each plant can draw more nutrients
and moisture out of the soil.  More nutrients make for healthier plants, and
significantly greater overall yields.  The Board believes Myconate could be the
key to changing the face of farming. The safety and ease of application of
Myconate means that management practices need not be over-hauled. The procedure
is a straightforward blending process, either tank mixing the Myconate with the
fertilizer during planting, or applying the Myconate to the seed before
planting.


During 2006, Myconate tests are being performed in numerous countries in the
Americas and Europe, in different soil and climate conditions, with the tests
conducted on many different crops and using a range of application methods. The
results for four of the trials harvested so far this year are shown in the
following Table. The results from all of our corn and soybean trials will be
reported later.

Sorghum   Tamaulipas, Mexico                    47.1%            Grain yield

Tomatoes    Provence, France         13.3% (saleable)    Processing tomatoes


Our trials continue to generate interest in Myconate among its target markets
prior to commercial rollout.  PHC is currently in discussions with several major
agrichemical and seed companies concerning optimal arrangements for the
commercialisation of Myconate in the principal row crops. Other strategies are
being explored for the smaller acreage crops.


John Brady, CEO of Plant Health Care, commented on the results, 'The current
trials on cotton and tomatoes have been exceptional and further tests on a
variety of different crops are underway, leading us to believe that Myconate
could be more widely accepted than previously believed.


'We are very excited about the progress being made on current round of Myconate
tests. These successes have put us ahead of where we expected to be and it bodes
very well for the future. We expect to sign the first licensing agreement with a
major agri-chemical company in 2007, one year ahead of schedule.'
