Aggiungi Tag | Riassunto: | Evaluation of acaricide effect of essential oil congona (Peperomia inaequalifolia Ruiz & Pav . ) on strawberry plants ( Fragaria vesca L. ) The search for new alternatives and environmentally friendly compounds, such as natural products and metabolites of plant origin, which generate minimal damage, is an important line of research in integrated pest and vector control. In Ecuador, a major cause of lost productivity in crops is the presence of the mite Tetranychus urticae Koch (Acari: Tetranychidae). The use of chemicals, such as pesticides, is deemed to be needed to combat this mite to circumvent the loss in productivity. However, the inappropriate use of agrochemicals has led to long-term decline in soil productivity and erosion problems in the surrounding towns affecting levels of community health, such as respiratory and skin conditions. This paper investigated the essential oil from the leaves of the Peperomia inaequalifolia plant, as an alternative method of pest control, in different concentrations, being used for the statistical analysis of 0.5%, 0.25% and 0.125%. Two techniques were used to determine the concentration. Two techniques were used to determine the concentration, in vitro technique. It was considered volatile essential oil at different concentrations. After a comparison with a standard substance miristicina (Sigma Aldrich) it was performed, resulting in lower mortality in the mites. The results prove that the synergy of essential oil compounds is most effective in comparison to the use of miristicina. 12 The second technique was by direct spray in the infested plant at the same level of concentrations. After performing the simple Anova, it was determined that there were significant differences between the two proposed methods. In this research, the efficiency at very low Congona essential oil as an alternative method for effective control of mites dose is concluded. |
