To evaluate the effectiveness of eco-friendly treatments based on detergents classified
as non-hazardous and black soap on the pest Tetranychus urticae Koch 1836, and their predators
(Euseius stipulatus Athias-Henriot, 1960, Typhlodromus sp., Phytoseiulus persimilis Athias-Henriot,
1957), different treatments were applied to citrus orchards planted with Valencia late (Orange)
in the Mechraa Belksiri region of Morocco (T0 = control experiment; T1 = spirodiclofen 0.5 L/Ha;
T2 = 125 L/Ha (5%) of black soap; T3 = detergent; 4 L/Ha of Oni product + 2 L/Ha of Tide product).
The results obtained during the whole monitoring period indicated that the three treatments
used, namely spirodiclofen, black soap, and detergents, ensured a reduction in the rate of population
of the pest T. urticae compared to the untreated plot. In the untreated plot, the average was
45.01 A 4.90 mobile forms, while the plot treated with spirodiclofen it was only 21.10 C 2.71,
the black soap 31.49 B 3.35, and in the plot treated with detergents, the average was similar
to that obtained by spirodiclofen (22.90 C 2.18). On the predators (E. stipulatus, P. persimilis,
and Typhlodropmus sp.), the black soap and the treatment with detergents were less harmful compared
to the chemical spirodiclofen.
