                          Interim Test Results Update

Plant Health Care (AIM: PHC.L) is pleased to announce that the first tranche of
data from its 2005 Myconate(R) test programme is now available. PHC's Myconate
(R) product is based on Formononetin, a compound which has been demonstrated to
increase the yields of row crops. The results of the test programme (summarised
below) in the main validate the properties of Formononetin and the Directors
believe the test results emphasise the significant global commercial potential
for PHC's Myconate(R) product in the crop growing sector.

The tests were performed in four countries in the Americas and in Europe, in a
variety of different soil and climate conditions. The tests were conducted on
many different crops and by using different application methods, to help
establish the best routes to full commercialisation for the product.

Some 60 trials were originally scheduled to take place in 2005; of this number
36 are expected to be seen through to completion. The balance either did not
commence or did not produce reliable data for reasons including adverse weather
conditions and inadequate control data and/or measurement.

The results of 15 tests have been compiled to date. Although, certain tests did
not indicate yield increases, they provided very valuable information in terms
of gaining a better understanding of appropriate and inappropriate application
methods for the Myconate in commercial settings.

The remainder of the trials have been very successful and confirmed previously
observed yield increases in the range of 5% to 30% with standard seed coating
techniques and where 'side dressing' (i.e. mixing the Myconate with fertiliser
at time of planting) has been employed. The best results have been observed from
the tests on corn and soy bean, the two largest row crops in the world.
Especially encouraging are the independent results from the French corn studies
on non-GMO corn seed. In this large scale trial the corn yields from Myconate(R)
treated seed were consistently 12%-24% higher than the control fields.

Data from the remaining 21 trials is yet to be received and remains to be
analysed. Some of these trials replicate application methods already observed to
be flawed and on these the Group has no expectation of positive results. The
remaining trials are expected to produce positive results. These results will be
announced at the time of PHC's preliminary results for the year ended 31
December 2005, expected to be in March 2006.

John Brady, CEO of Plant Health Care commented on the initial results, 'We are
delighted to see the initial results are consistent with prior years', but we
are not surprised. In the 2005 trials, we varied the application methods to
determine the response of Myconate(R) under a wide variety of circumstances and
have learned a great deal from these tests. Not all application methods
demonstrated successful yield increases; however we believe we have perfected
our ability to apply the product, including in some new and unique ways, and
also found positive responses from new crops such as pinto beans, potatoes and
sunflowers.'

'We are awaiting feedback from some large chemical and seed company trials which
will be available in the first quarter of 2006. These results will help us
better determine the best routes to full commercialisation.

We are very excited with the trial data received so far, which gives clear
indication that Myconate applied as a single seed coating or as a side dressing
can significantly improve yields across a wide variety of crops. The greatest
improvements have been seen in higher volume row crops such as corn and soy
bean, but important improvements have also been seen in higher value crops, such
as tomatoes and strawberries.'
