Efficacy of ozone in the microbiological disinfection of maize grains

Abstract This research aimed to determine the effectiveness of ozone in the microbiological disinfection of maize grains. Two kg samples of maize grains were used with moisture contents of 14.4% (w.b.), and 94% and 97% of natural infection by Penicillium spp and Aspergillus spp, respectively. The gas was applied at a concentration of 2.14 mg L-1 and flow rate of 5.8 L min-1 for 370 min at 25 ºC ± 2 ºC in order to determine the ozone concentration and saturation time of the maize grains. The experiment was installed according to a split plot design, with two treatments in the plots (atmospheric air and ozone gas) and exposure times of (0, 10, 20, 30 and 50 h) in the subplots, in a completely randomized design. It was shown that the ozone concentration and saturation time in the grain mass were 0.9874 mg L-1 and 138.56 min, respectively. Ozonation was effective in controlling storage fungi in the grain mass with 50 h of exposure to the gas, reducing the rate of incidence of Aspergillus spp (78.5%) and Penicillium spp (98.0%), thereby confirming its fungicidal effect under the conditions presented.

Problems arising from silica sand mining are decreasing soil fertility, as well as the presence of high heavy metals such as Fe and Al, which inhibits the growth of revegetation plants. The purpose of this study was to analyze the response of the growth of balsa seedlings (Ochroma bicolor Rowlee.) on silica sand post-mining media treated with MycoSilvi, compost, and lime and determine the most optimal combination of MycoSilvi, compost, and lime treatment. This study uses a completely randomized design (CRD) with a split-plot design with 3 treatment factors, namely the addition of MycoSilvi, compost, and lime. Each treatment consisted of five replications. The results showed that the planting media that were not treated (control) was not able to support the growth of balsa seedlings. The interaction of MycoSilvi, compost, and lime significantly affected the height, diameter, biomass, and percentage of mycorrhizal colonization parameters, and significantly affected the plant chlorophyll content. The combination of MycoSilvi type 1 treatment, namely Glomus mosseae and lime (C0K1M1) type, resulted in the highest total growth rate, diameter, biomass, and colonization percentage compared to other treatments. The addition of lime and compost to the growth medium can reduce the degree of mycorrhizal dependency of balsa seedling.

The present study aimed to evaluate the leaching potential of Picloram in Ultisol columns under different rainfall amounts. For such, 30 treatments were evaluated (one soil associated with three levels of rainfall and ten depths).The experiments were arranged in a split-plot design, in a completely randomized design, with four replications. PVC columns of 10 cm in diameter and 50 cm in length were filled with these soils, moistened, and placed upright for 48 hours to drain the excess water. The herbicide was applied and rainfall simulations were carried out at specified intensities, according to the treatments, to force Picloram leaching. After 72 hours, all the columns were arranged in a horizontal position and opened lengthwise. Then, soil sampling was carried out every 5 cm of depth for subsequent herbicide extraction and quantification and analysis by high performance liquid chromatography. The remaining soil samples were placed in plastic pots, and, at the respective depths, the indicator species Cucumis sativus was sown. Twenty-one days after the emergence (DAE) of the indicator plants, evaluations were conducted to verify the symptoms of toxicity caused by Picloram in the plants. It was concluded that Picloram leaching is directly dependent on the volume of rain applied. The herbicide reached the deepest regions in the soil with the highest intensity of rain. The results obtained by bioassay were in agreement with those found by liquid chromatography.

Abstract: Fungi are considered as the most important among pathogens due to the higher number of species and to the damage caused both in yield and in seed quality. Thus, aimed to verify the effect of fungicide and insecticide treatment on sanitary quality and physiological performance of soybean seeds before and after storage. Seeds from cultivars NS 7494, NS 8693 and NS 7338 IPRO were used, which were analyzed separately by a completely randomized design in a 3 x 6 factorial design, being three chemical treatment applications: 1) treated and evaluated; 2) treated, stored and evaluated; 3) stored, treated and evaluated; and six mixtures of fungicides and insecticides: (Imidacloprido + Tiocarbe) + (Carbendazim + Tiram), (Imidacloprido + Tiocarbe) + (Metalaxil-M + Fludioxonil), Thiamethoxam + (Carbendazim + Tiram), Thiamethoxam + (Metalaxil-M + Fludioxonil), (Fipronil + Piraclostrobina + Metil-tiofanato) and the control, which was added only water. The healthy test, germination, cold and accelerated aging tests were evaluated. Seed treatment products require at least two months to be effective in controlling Penicillium spp. and Fusarium spp. The mixtures containing Carbendazim + Tiram in its composition are efficient in the control of pathogens regardless of the application time of products.
