The aim of this work was to study the effect of the interaction between castor bean oil (Ricinus communis) and jatropha oil (Jatropha curcas) on the aphid, Myzus persicae. The experiment was realized at the Institute Federal of Espírito Santo in Brazil. Tests were conducted in a completely randomized design, with 11 treatments and 10 repetitions, arranged in a factorial arrangement of 11 (interactions between oils) x 2 (application forms). The concentration used in this test was 3 %. Treatment interaction ratios were 0-100; 10-90; 20-80; 30 -70; 40-60; 50-50; 60-40; 70-30; 80-20; 90-10; 100-0 % jatropha and castor bean oil, respectively. Tests of direct and indirect application were performed. The evaluations were performed 24, 48, and 72 hours after the applications. For both forms of application, there were significant mortalities. Mortalities greater than 70 % were observed when the interaction contained more significant amounts of jatropha than castor bean. However, a negative interaction was observed between concentrations with similar proportions. In conclusion, for both application forms, the interaction between jatropha and castor bean oils effectively reduce the population of M. persicae.

“…It can be consumed fresh, cooked, or processed (Viana et al, 2021). From an economic perspective, the crop is particularly attractive because it has a short return-oninvestment period, even for small-scale systems (Melo et al, 2019). In addition to having high economic importance for farmers, vegetables such as collard greens are also valued by consumers for their nutritional properties, given their high antioxidant activity and ability to scavenge reactive oxygen species, which are linked to the development of chronic diseases in humans (Chawner & Hetherington, 2021;Fayet-Moore et al, 2020) frequency of intake, proportion meeting ADG recommendations, most popular food groups, intake at each reported eating occasion, and the profile of high and low vegetable consumers (based on the median servings).…”

This study evaluated the bioactive effects of Melaleuca alternifolia essential oil on the behavior and mortality of Ascia monuste orseis caterpillars. The experiment was conducted at the laboratory under controlled conditions using a completely randomized design with six treatments, represented by A. monuste orseis caterpillars fed collard leaves treated with 0 (control), 5, 10, 20, 30, or 40 mg mL−1 essential oil. Each treatment consisted of five replicates of four third-instar caterpillars. Mean daily intake of collard leaves, feces production, mortality, and behavioral changes were assessed for 15 days after the beginning of the experiment. Data on leaf intake and feces production were subjected to analysis of variance by the F-test; when significant differences were found, data were subjected to regression analysis. Corrected mortality rate was calculated and subjected to analysis of variance by the F-test followed by Tukey’s test at the 5% significance level for comparison of means. The median lethal dose (LD50) was also evaluated. Two very clear feeding behaviors were observed, one in caterpillars exposed to essential oil concentrations of 5, 10, and 20 mg mL−1, which showed little difference in feed intake from the control, and the other in caterpillars exposed to the highest concentrations (30 and 40 mg mL−1), which showed a decrease of 76 to 93% in feed intake compared with the control. Lower leaf intake resulted in a decrease in feces production, and the negative effects increased linearly with essential oil concentration. The mortality curve showed a linear and positive response to essential oil concentration, reaching 100% in insects exposed to the highest concentrations. The LD50 was 13.93 mg mL−1.

“…Leafy vegetables, flowers, and roots can be consumed fresh, cooked, and processed. The production of these vegetables in Brazil has been growing exponentially in the last decades, due to its economic importance, with significant production volumes in different states and a rapid monetary return for producers in small-sized areas (Melo et al, 2019).…”

Physiological factors in the production of cabbage under no-tillage

et al. 2022

The no-till system promotes benefits that extend not only the characteristics of soil improvement, interfering in the quality and productivity of the plants, thus improving physical, chemical, and biological attributes of the crop and resulting in profitability to the producer. The present study evaluated the agronomic development of cabbage according to different cover plants. The experiment was performed in the field, in the Vegetable sector of the University of Rio Verde - UniRV, Rio Verde, GO. The cover plants used were millet (Pennisetum americanum (L)), sunflower (Helianthus annuus), brachiaria (Brachiaria decumbens), and crotalaria (Crotalaria juncea). The studied greeneries were cabbage (Brassica oleracea), Astrus plus hybrid. The parameters evaluated to analyze the physiological development were: the plants’ height, number of leaves, and cabbage diameter. The results were submitted to the descriptive statistical method with analysis of means, covariances, and correlations, using the Matlab program. Plant growth data were submitted to the analysis of variance, and when significant, the cover plant factor was compared by Fisher’s test, and the factor days after planting was analyzed by regression. The cabbage showed a higher mean height (cm), leaves, and diameter with the sunflower covering plant. The millet was the best plant to increase the cabbage’s mean productivity.
