fertilizers and other synthetic and organic products. The organic production of food plants requires a careful_x000D_
assessment of all possible avenues for pest and disease control, and efficacy data and modes of action need to_x000D_
be well studied. Sources of organically-certified products for disease control in Canada are currently limited to_x000D_
a few well-known and widely used materials that include formulations of bacteria and chelated chemicals._x000D_
Plant extracts have attracted wide interest but the consistency and stability of the product has not enabled their_x000D_
widespread use. Plants naturally contain a wide range of phenolic compounds, terpenoids, flavonoids,_x000D_
phytoalexins and other chemicals that have potential antifungal properties. In this research, formulated extracts_x000D_
derived from the Indian neem tree (Azadirachta indica) and the Karanj tree (Pongamia pinnata) will be tested_x000D_
for management of two important fungal pathogens affecting greenhouse cucumber plants, and which have_x000D_

greenhouses. These tree species contain high levels of tetranortriterpenoid (limonoids) in seeds, leaves and bark_x000D_
(neem) as well as high levels of flavonoids (karanja) in seeds. The invitro toxicity of these formulations will be_x000D_
tested against mycelial growth and spore germination of the two pathogens. This will be followed by_x000D_
assessment of temperature and pH effects on product activity. Greenhouse experiments will evaluate whether_x000D_
the formulations have activity on plant growth (measured as height and dry weight) as well as disease reduction_x000D_
on the roots (Fusarium) and leaves (powdery mildew) of the two plant species. The research will investigate_x000D_
whether induced levels of phenolic compounds, antioxidants and signalling molecules such as jasmonic acid_x000D_
and salicylic acid, are increased in treated plants. The results will provide additional insights into the_x000D_
