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).
