In: Zagazig Journal of Agricultural Research 2012.v.39(3)Summary: The effect of spraying three novel polymeric compounds (Homopolymer, Pure acrylate and Styrene Co-polymer) at three different concentrations (5,10 and 15%) on the development of wheat leaf rust caused by Puccinia triticina Eriks. was assessed on two wheat cultivars (Sakha 93 and Sids 1) at seedling stage. Spraying polymeric compounds before rust inoculation, significantly reduced pustule size and number of pustules/cm\2 and leaf area but not affected incubation period. However, infection type (IT) was significantly affected through some of infection type produced only flecks which were not developed to pustules. These prepared polymers consists of three groups depending on the monomers type of polymers (homo or co-polymer). The efficiency of these polymers depended upon their polymeric types and concentrations.
