Abstract:

Six different phytobiocides i.e. garlic, ginger, neem oil, onion, pepper and turmeric were evaluated for their pre- and post-inoculation time of application on a susceptible pea variety ‘Meteor’ under artificial epiphytotics of powdery mildew at the NWFP Agricultural University Research Farm. Peshawar during 2002-2003. The application of these biocides at both stages was better than their no application in reducing the disease severity. However, the use of some phytobiocides was effective at the pre-, while that of others at the post-inoculation stage. Turmeric proved to be the best biocide when applied prior to inoculation of the crop. It is of low cost and can be recommended as an eradicative phytobiocide for control of powdery mildew in pea.
