In the second season (2013/14), where wheat cultivar “Sids
1” was used, data presented in Table 7 revealed that the application
of either one or two sprays of all used plant extracts
showed high efficacy against leaf rust, reducing the ACI in comparison
with the untreated control. The treatment of twospray
application seemed to be more effective than one spray.
For one- or two-spray application, the most effective treatment
was neem (89.59 and 93.75% efficacy, respectively), which
was more effective than the fungicide Sumi-8 (for one-spray
application) and had equal efficacy with the fungicide for the
two sprays (Table 7).
