“…In this process, technical and logistical matters determine that seeds be treated before being packed and then stored up to the time of sowing (Brzezinski et al, 2015;Santos et al, 2018). However, storage of treated seeds can have some unintended consequences, such as possible detrimental effects from the chemical products on the seeds, as reported for some molecules by Dan et al (2010), Piccinin et al (2013), Ferreira et al (2016) and Santos et al (2018).…”

Due to increased use of treated seeds, studies are necessary in relation to the effects of the treatments and their possible consequences on seed quality. The aim of this study was to evaluate phytotoxicity according to when phytosanitary products are applied on soybean seeds and their effect on seed physiological quality and field performance. A completely randomized experimental design was used in a 9 × 2 factorial arrangement involving 9 seed treatments (fungicides and insecticides) and two application times (60 days before sowing and at the time of sowing in the field). Moisture content was determined and tests were performed to ascertain physiological quality (germination and germination under water restriction). Root and hypocotyl length, seedling length, and vigor and uniformity indices were evaluated with the assistance of Vigor-S®. In the field, the following determinations were made: plant height at 30 and 60 days after emergence, first pod height, number of pods per plant, number of seeds per pod, and yield. Early seed treatment in the soybean crop can affect initial development of the plants, but it does not affect yield. The phytotoxicity caused by the soybean seed treatment was observed in the root length characteristic.

“…Several studies had shown that the application of the insecticide thiamethoxan negatively affect the physiological quality of seed (Castro et al, 2008;Piccinin et al, 2013). In this study, no significant difference regarding to seed vigor was observed from the noninoculated and non-treated control when only thiamethoxan was applied to the pre-inoculated seeds even after 51 days of storage (Table 3).…”

“…Nevertheless, industrial seed treatments still face many challenges that need to be addressed regarding the storage period of the seed and the compatibility of agrochemicals with inoculants. Previous studies demonstrated that seed treatment with fungicides and insecticides (Pereira et al, 2010a;Dan et al, 2012;Ferreira et al, 2016;Camilo et al, 2017) as well as the period of storage (Krohn and Malavasi, 2004;Dan et al, 2010;Piccinin et al, 2013) can have negative effects on physiological quality of soybean seed. As a result, seed with low vigor can decrease seedling emergence (Khaliliaqdam et al, 2012) and reduce yield (Scheeren et al, 2010), which could seriously lead to unfeasibility of industrial seed treatments.…”

Industrial seed treatment of soybean [Glycine max (L.) Merr.] has increased over the last years. New technologies have been developed to allow the inoculation procedure, which is traditionally done at the day of sowing, to be performed with the industrial treatment days or even weeks before sowing. Since little is known about the compatibility of agrochemicals and pre-inoculation, the objective of this study was to determine whether the storage period and the combination of fungicides and insecticides could negatively affect the physiological quality and yield of soybean seeds that were pre-inoculated. Soybean seeds received fourteen seed treatments that consisted of different fungicides and insecticides and were pre-inoculated with Bradyrhizobium elkanii. The seeds were treated and stored for 51 days until it was sown in the field. Every 17 days the physiological quality of the seed was assessed. The results shown that pre-inoculation did not affect the physiological quality of seeds. However, some combinations of agrochemicals, as well as storage period reduced seed vigor and seed germination, while increased abnormal seedlings. The findings of this study indicated that some combinations of fungicides and insecticides can have adverse effect on the physiological quality of seed that is stored for up to 51 days before sowing, but none of them jeopardized the nodulation and soybean yield under field conditions.

“…For the effect of storage period (Figure 1D), our results were in agreement with those of De Moraes Dan et al (2013), who found that in soybean seeds treated with the insecticide thiamethoxam, seed vigor was drastically reduced by a storage period of 90 days. In another study, Piccinin et al (2013) also found that soybean seeds treated with the insecticides fipronil and thiamethoxam affected the vigor of seeds exposed to storage for 180 days under natural conditions.…”

Treatment of early seeds, using new combinations of chemicals has been increasingly adopted, however, its effects on seed quality during storage are still not completely understood. The aim was to evaluate the physiological seed quality of two soybean cultivars treated with different combinations of chemical products during the storage period. The experiment was arranged in completely randomized with four replications in a factorial 7x5 design for each cultivar, with seven seed treatments and five evaluation periods (times) during storage (0, 60, 120, 180 and 240 days). The treatments were: 1) fipronil + pyraclostrobin + methyl thiophanate; 2) imidacloprid + thiodicarb + carbendazin + thiram; 3) abamectin + mefenoxam + fludioxonil + thiamethoxam + thiabendazole; 4) carbendazin + thiram; 5) fludioxonil + mefenoxam + thiabendazole; 6) carboxin + thiram and 7) control (no treatment). The physiological seed quality was evaluated by the following tests: germination, accelerated aging, seedling emergence in sand and shoot and root length of seedlings. The physiological quality of soybean seeds decreased during storage in all treatments (including the control). The treatment with the insecticides imidacloprid + thiodicarb associated with the fungicides carbendazin + thiram markedly reduces the physiological seed quality of the tested soybean cultivars.
