Control of Phytophthora spp. with grapefruit extract

Control of Phytophthora spp. with grapefruit extract

Bulletin OILB/SROP 24(3): 247-250

ISSN/ISBN: 1027-3115

Addition of grapefruit extract (Biosept 33 SL) to peat leachate at 1.6 micro g/cm3 strongly inhibited zoosporangia production of Phytophthora cryptogea. At 200 micro g of the product/cm3 sporulation was not observed. Amendment of peat with grapefruit extract at dose 165 micro g/cm3 resulted in a drastic decrease of colony forming units of the pathogen and suppression of its development within at least one month.
