PLANT HEALTH CARE PLC

("Plant Health Care" or "the Company")

Market Update

Plant Health Care (AIM:PHC), a leading provider of naturally derived products to the agriculture industry, announces that the Board has conducted a review of its partnership discussions and is providing the following update.

Partnerships are an important source of future revenue for PHC. We are involved in multiple discussions with industry partners who are interested in commercialising our products and intellectual property, and in particular our Harpin and Myconate platforms. PHC remains confident that it can deliver substantial value to shareholders through the successful implementation of its partnership agreements. Nonetheless, the Board recognises that the precise timing of agreements and revenues can be subject to a number of uncertainties because of factors such as the outcome of field trials and the progress of registration processes for new products.

The Board has resolved to adopt a more cautious approach to budgeting for future revenues from its partnership discussions. We believe this should give investors a better understanding of PHC's prospects in the short and medium terms.

In accordance with this new policy, we are today announcing that:

A further update will be made as part of the Company's 2012 full year results, expected by the end of March 2013.
