Seed soaking or foliar spray treatments of wheat seedlings
with the plant extracts reduced the number of pustules/
leaf, with foliar spraying being more effective. In this regard,
neem extract was the most effective treatment. It gave 100%
control of the disease when applied one or four days after inoculation.
After 22 days from inoculation, pustules started to
appear on plants treated with the fungicide (Sumi-8), while no
pustules developed on plants treated with neem, white cedar,
garden quinine, or clove extracts. Applying a foliar spray at the
mature plant stage showed high efficacy in reducing the leaf
rust infection (ACI) and neem extract was the most effective
treatment. Two-spray application seemed to be more effective
than one spray.
