摘要:

Seven date palm varieties were screened against leaf spot under field conditions at Haryana Agricultural University, Hisar. Results over 3 yr observations revealed that variety Khadrawi was resistant, contracting disease intensity less than 5%, four varieties,viz.Hallawi, Hayani, Shamran and Zaidi were found susceptible whereas Barhee and Medjool were highly susceptible to leaf spot. Eight fungicides were evaluated for their efficacy against leaf spot under field conditions. Data from 2 yr experiments revealed carben‐dazim at the rate of 0.2% to be most effective followed by thiophanate methyl, while captafol was less effective.
