Foliar spraying treatment on wheat seedlings The plant extracts were tested for their efficacy in control- ling leaf rust using foliar spray application on wheat seedlings in the greenhouse.For each treatment,grains of the highly sus- ceptible wheat variety Morocco were sown in pots (15 cm diameter) with three replicates (10–15 grains/pot).Sumi-8 fun- gicide was used as standard treatment (positive control). Seedlings sprayed with water supplemented with four drops ofTween 20 were served as negative control (untreated control). All extracts were separately sprayed one day before inocula- tion with uredospores and one and four days after inoculation with uredospores. Inoculation and incubation were per- formed as described by Ref.[25].After 15 days from inoculation, disease severity was rated in terms of infection types and number of pustules/leaf was recorded.
