Different control methods have been applied to control the
land snail (Xeropicta derbentina
and Xeropicta krynickii) but the chemical method is
realized to be the most effective method to control this
pest. The main goal of this work
was to determine the efficacy of methaldehyde,
Ferricol, Snail repellent tape and Snail repellent
paint (Sabzrang) on this pest. Methaldehyde, Ferricol
were used as bait around citrus trees and Snail
repellent tape and Snail repellent paint rolled up around
main stem of the citrus trees. The
life snails on citrus trees were monitored at
2, 15, 29, 36, 68 and 98 days after treatments.
Analysis of variance showed that there
were significant differences between treatments and control,
and also significant differences were found among treatments
(p < 0.01). LSD and Tukay-Test among the above
treatments has shown that repellent band
and methaldehyde
with 5 ± 1.3
and 10.6 ± 0.9 percentage
of the alive snail on trees, respectively, were more
effective than repellent color
and biological toxin with
14.2 ± 2.6 and 31.3
± 3.9 percentage alive snail on
citrus trees and significant differences with control,
respectively. The control efficacies of the
methaldehyde and Ferricol
were 91.87 and 82.63%, respectively; also the
total control efficacies of the Snail repellent tape
and Snail repellent paint were 95.22 and 82.26%,
respectively, after 2, 15, 29, 36, 68 and 98 days of post
treatment. Therefore the Snail repellent tape and
methaldehyde were better than the other treatments for the
management of land snail population.
