“…Currently, with the increasing demand for industrial seed treatment, many seed companies have worked in an intense way in the short period of time that precedes sowing. This creates the need for results that provide indications of the best spray volume, storage period and environment to better plan this step of production, as well as efforts to reduce costs (Pereira et al, 2018).…”

The increase in spray volumes in industrial seed treatments may increase the deterioration and reduce the physiological potential of seeds, especially when stored in unfavorable environments. The aim of this study was to evaluate the effect of spray volumes obtained by the combination of different chemical products, via industrial treatment, on the physiological potential of soybean seeds during storage in different environments. A completely randomized experimental design was used in a 5 × 3 factorial arrangement, with four replications. The factors were five spray volumes (0, 600, 1200, 1800 and 2400 mL.100 kg-1 of seeds), obtained from the combination of different products in commercial use, and three storage periods (0, 60 and 120 days), evaluated separately in two environments (storage without climate control and cold storage). The following variables were evaluated: germination, first germination count, seedling emergence in sand, emergence speed index, seedling length (total, shoot, and root) and dry matter (shoot and root). The physiological potential of soybean seeds is reduced by increasing the spray volume used in the industrial treatment and by prolonging the storage period. However, this effect is mitigated by the controlled conditions of cold storage.

“…With the technological advances of brazilian agriculture, seed companies are adopting new techniques that maximize crop yields, for example, the creation of an industrial seed treatment process [2,3], called industrial seed treatment (TIS), in which seed lots are treated during the processing phase, and then bagged and stored until sowing [4][5][6][7][8][9][10]. Through this innovative technique, new formulations containing fungicides, insecticides, nematicides, stimulants, micronutrients, inoculants can be used in the same treatment [11][12][13], which can maximize the efficiency of products, helps protect the applicator and avoid environmental contamination.…”

This study aimed to evaluate the application of chemical defensives and long-life inoculant, in mixtures or not, under the nodulation process of plants and the quality of soy seeds during storage. The first was carried out in a greenhouse and completely randomized design was used, in an 8 x 2 factorial scheme, with three replications, and the treatments consisted of applications of seed treatments via industrial: (T1 - control; T2 - MaximAdvanced; T3 - Fortenza; T4 - long-life inoculant; T5 - MaximAdvanced + Fortenza); T6 - MaximAdvanced + long-life inoculant; T7 - Fortenza + long-life inoculant; T8 - MaximAdvanced + Fortenza + long-life inoculant), which were sown in pots containing soils from two cultivation areas; the second in the laboratory, using a completely randomized design, in a factorial scheme 8 x 7, with four replications, with treatments consisting of eight combinations of industrial seed treatment in the greenhouse, stored for two months. That seed treatment industrial with fungicide/insecticide/inoculant, applied in isolation or not, does not influence the soy nodulation process. Soy seeds, regardless of the type of treatment received with fungicide/insecticide/long-life inoculant products, in mixtures or in isolation, may be stored for a period of 40 days for commercial purposes.

“…In addition to performing analyses with untreated cotton seeds, chemical treatments have been used, with the aim of minimizing problems caused by pathogens, ensuring the protection and/or eradication of pathogens associated with the seeds (Chitarra et al, 2009;Kubo et al, 2012;Braghin et al, 2014). However, some products (insecticides and fungicides) can cause phytotoxicity to the seeds and seedlings at the time of the germination test (Pereira et al, 2018;Del Bem-Junior et al, 2020;Tunes et al, 2020).…”

The objective of this study was to assess the impact of incorporating vermiculite into germination tests for both chemically treated and untreated stored cotton seeds. To that end, two independent experiments were conducted using cotton seeds of the cultivar DP1746B2RF under chemical treatment with a mixture of fungicide, insecticides, and nematicide; and both experiments were set up in a completely randomized design with four replications. In Experiment 1, the objective was to determine the ideal water volume for moistening the vermiculite. Four water volumes were used: 1.5, 2.0, 2.5, and 3.0 times the weight of the dry vermiculite. Experiment 2 was conducted in a 2 × 2 × 2 triple factorial arrangement consisting of two substrates (germitest paper and germitest paper + vermiculite), two treatments (chemically treated seeds and untreated seeds), and two storage periods (0 and 150 days). First germination count and germination were evaluated in the two experiments. From the results found in Experiment 1, the water volume corresponding to 3.0 times the weight of the vermiculite provided the best conditions for germination. In Experiment 2, the most appropriate substrate for conducting the germination test of untreated and chemically treated cotton seeds is vermiculite, which led to rapid germination and uniform seedling development.
