1	Introducing FenStop™ Fungicide Your new solution for Downy Mildew, Pythium and Phytophthora Disease Control
2	FenStop Position FenStop™ is a highly effective fungicide which provides superior long lasting curative and preventative control of Downy Mildew and Aerial Phytophthora with excellent crop safety. FenStop also provides an effective new tool for control of Phytophthora and Pythium root rot in ornamental production.
3	FenStop^™ Fungicide Overview A member of the Imidazolinone family, fenamidone is active at the biochemical level thru inhibition of mitochondrial respiration by means of blockage of electron transfer. The product is both a preventative and curative fungicide displaying a protectant residual, translaminar and acropetal systemic activity. In worldwide testing fenamidone has demonstrated effectiveness against a broad range of the Phycomycete fungi. This includes the downy mildews ( Bremia, Peronospora, Plasmopara and Pseudoperonospora) as well as Pythium and Phytophthora.
4	Fenamidone Fenamidone inhibits mitochondrial respiration by blocking electron transfer. It exhibits good activity against spore germination and mycelial growth. It is active as both a preventative and curative fungicide demonstrating good residual performance on ornamentals. As a single-site mode of action fungicide, which is similar to that of the strobiliurins, there is a risk of resistance and cross-resistance. Therefore, the use of fenamidone will have to be managed to prevent the development of resistance to their similar modes of action.
