Insecticide application is the main way to control Diaphorina citri. However, it causes environmental contamination, has a negative impact on beneficial organisms, and leads to psyllid resistance. The essential oil of Piper aduncum has low toxicity towards the environment and contains dillapiol, which was proven to be effective against several crop pests. Here, we studied its efficacy against nymphs and adults of D. citri under laboratory conditions. Oils with three concentrations of dillapiol (65.2%, 76.6%, and 81.6%) at 0.5%, 0.75%, and 1.0% dilutions plus 0.025% adjuvant were tested. All treatments caused 90?100% mortality in nymphs. Topical treatments with oil containing 76.6% and 81.6% of dillapiol at 0.75% and 1% dilutions were effective (mortality less or equal 80%) in adults. However, the essential oil showed no residual activity against adults (mortality bigger or equal 30%). Because of its high efficacy against nymphs and adults, P. aduncum is a promising botanical insecticide for use in integrated pest management of D. citri. |

Silicon (Si) supplementation is related to the induction of different tolerance mechanisms, leading to higher farm crop yields. The objective of this study was to elucidate the Si action mechanisms as a beneficial element in primary, antioxidant, and osmoregulatory metabolism in sorghum plants cultivated in soil under two different water availability conditions. Plants of the sorghum BRS332 genotype, sensitive to drought, were cultivated in pots in greenhouse conditions until harvest. At the pre-flowering stage, the following treatments were applied: field capacity (irrigated plants), water deficit, field capacity with Si application, and water deficit with Si application. Water deficit was conducted over 12 days, after which water potential and photosynthetic rate analyses, and leaf and root harvesting for biochemical analyses were performed. After the water deficit treatment, all plants were returned to normal irrigation until harvest, when the yield components were analyzed. Si supply occurred via fertilization at a concentration of 2 mM applied to the soil in a volume of 250 mL per day over 17 days, which corresponded to a supply on the five days preceding the beginning of stress, plus a 12-day supply during the stress period. Si alleviated the water deficit in plants, resulting in higher water potential, photosynthetic rate, grain biomass, and harvest index. Si increased the antioxidant enzymatic activity, and increased non-enzymatic antioxidants such as ascorbate and osmoregulatory substances, including proline, soluble and reducing sugars, and sucrose. Plants treated with Si showed lower damage to cell membranes (lower lipid peroxidation). The beneficial effects of Si also extended to plants that were not subjected to the water deficit treatment. Si uses the peroxide pathway as a signal to regulate metabolic responses.
