Abstract:
This study was conducted in Sheikan locality at North
Kordofan State, Sudan in season 2016/2017 to assess post
harvest treatments for the control sesame seed bug a harmful
pest on sesame crop. Two experiments were done. In the first
experiment three treatments were used on sesame at harvest
time when sesame crop stacked in bundles to dry and
infestation with sesame bug built up in the field, in the first
treatment three bundles of sesame crop were put on the ground,
in the second treatment three bundles of sesame put on the
ground surrounded by Wood Ash and, in the third treatment
three bundles of the sesame crop surrounded by pesticide beside
the control which kept away from infestation. In the second
experiment 5 treatments were used in the first one the sesame
crop bundles were put on the ground (Zero level) and in the
treatments from second to the fourth Wooden benches
(Rakoopa) with four levels of height were used 25 Cm; 50 Cm,
75 Cm and 100 Cm and the control was kept away from
infestation. The experiments were executed using Randomized
Complete Design (RCD) with 4 replicates. After infestation one
kilogram of sesame seed was collected weekly for a month and
then transferred to the lab and 1000 seed weight obtained then
loss in seed weight Percentage calculated. Results showed that
when infestation of the bug built up in the field the seeds stored
on the ground surrounded by Wood ash had been affected
significantly (P< 0.05) with obvious reduction in weight of 1000
seeds while the seeds surrounded with pesticide showed no
reduction in weight in comparison with the control in the first
experiment period and, in the second experiment no significant
loss in weight observed during the examination period in
wooden benches (Rakoopa) with different levels in comparison
with the control and loss in seed weight of 1000 sesame seeds
reached 13.7% by the end of the month when bundles left on
the ground (zero level) and significantly differed (P < 0.05)
from the control and the wooden benches (Rakoopa)
treatments. It is clear use of wooden benches (Rakoopa)
treatments kept the crop save from the sesame seed bug damage
even in low height (25 Cm) although, use of pesticide gave the
same result but the expected hazard of chemical residues
upraise the use of wooden benches (Rakoopa) and might b
