| Abstract |
| Responding to municipal demands for sustainable acaricides, we assessed a novel microencapsulated bioactive formulation (Maria-pro®: Quercus-derived) for managing Tetranychus urticae outbreaks in urban agroecosystems, emphasizing compatibility with integrated pest management (IPM) frameworks. Experiments were conducted in a greenhouse plot of 5 x 7 m2 in the urban agricultural farm of Salamat green-space geographic coordinates Length 51.36 – width 35.65, in July 2024. Bioassays were performed in three replicates for two different concentrations of Maria-pro (2000, 2500 ppm). Also, water was used as a negative control, and Dayabon (2500 ppm) was applied as a positive control. Four eggplant leaves were randomly sampled from urban farm fields. Specimens were segregated into egg, larva, and nymph developmental stages, followed by efficacy evaluation of Maria Pro® and Diyabon® concentrations. The survivors at different stages were counted one, three, and five days after treatment. The significance of the effect of the treatment status was statistically evaluated by using the General Linear Model (GLM) followed by the Duncan test. Bioassay results showed significant differences among the experimental tests. The population in the negative control group increased until the final day. Mario-pro 2500 ppm made the highest mortality in mite as 92.65±1.21% the following day, followed by Maria-pro in 3 day with 86.73±1.22% and Dayabon with 86.2±3.17%. The Interaction of day and pesticide treatment showed a significant difference, the highest mortality rate was recorded for Dayabon as 98±1.06% at day five. Therefore, micro-encapsulation of Maria-pro has the potential to be used as a suitable alternative to the chemical pesticides in urban pest control. Additionally, no phytotoxicity was observed at the tested concentrations. |
