“…In this study, doses below the tolerated limit were used (Table 1). In relation to the treatment with fungicides (carbendazim and thiram), positive effects have been reported on physiological performance (Pereira et al, 2011) and on soybean seed health quality (Ferreira et al, 2019), also corroborating the results of this study (Tables 2, 3, and 4).…”

Computerized analysis of seedling performance in evaluating the phytotoxicity of chemical treatment of soybean seeds

et al. 2021

Chemical treatment of soybean seeds is very important to ensure successful crop establishment. However, problems such as phytotoxicity of product combinations that can reduce seed physiological performance require attention. The use of computational resources has shown potential in identifying phytotoxic effects and contributing to the steps of quality control of treated seeds. The aim of this study was to determine if computerized image analysis of seedlings enables the phytotoxicity of chemical treatment of soybean seeds to be assessed in an effective and simplified manner. Samples from two soybean seed lots were treated with fungicides, insecticides, micronutrients, and their combinations, as well as with polymer and drying powder (coatings). After chemical treatment, the seeds were evaluated for germination, first germination count, seedling emergence in sand, accelerated aging, and seedling performance with and without the correction of regions not automatically demarcated (Vigor-S). We found high correlation of the Vigor-S parameters with the traditional tests for detection of phytotoxic effects of chemical treatment, regardless of correction made in the system. Computerized image analysis of seedlings is an effective and highly sensitive resource for evaluating possible phytotoxicity effects due to chemical treatment of soybean seeds.

“…Chemical treatment of soybean seeds is used against biotic interferences after sowing (Ferreira et al, 2019). Especially soil pathogenic fungi and insect pests can have negative impacts in the initial stages of crop development (França-Neto et al, 2016) and on establishing plant stand.…”

“…The pathogen attack on seeds is one of the factors that leads to the physiological quality loss, reducing the germination rate and the vigor of the seed lots, which end up precluding the final stand of the crop, resulting in productivity and economic losses to the farmer. Fungi are considered as the most important among pathogens due to the higher number of species and the damage caused both in yield and seed quality [29]. The mixture containing Carbendazim + Thiram in its composition are efficient in the control of pathogens regardless of the application time of products [29].…”

Fusarium - An Overview of the Genus

The incidence of the Fusarium genus causing root rot is reviewed in crops showing high importance for food supply and to obtain regular income by farmers in the highlands of Northern México. Pathogen incidence was evaluated under field conditions in multiple sampling locations for common beans (Phaseolus vulgaris L.) and several chili peppers (Capsicum annuum) local cultivars (landraces and bred cultivars). Five commercial plots for registered and certified seed were also evaluated in common beans to be used in the ‘seed refreshing program’ implemented for the cultivar Pinto Saltillo, considered as the main variety sown in the highlands of México. High Fusarium genus incidence and its interactions with other fungi species, such as Rhizoctonia solani and Pythium spp., cause high losses in plant population, commercial yield and seed quality in food crops grown in Northern México. The natural incidence of plant disease caused by the Fusarium genus and its negative effect on crop survival and the reduction of commercial yield and seed quality is fully reviewed. Plant disease resistance, crop breeding and the influence of the environmental conditions were also considered.

“…The fungus is transmitted by seeds, which are responsible for introduction and significant concentrations of the inoculum in growing areas. Seeds are an effective vehicle for dissemination of this organism (Maringoni and Barros, 2002;Sartori et al, 2004;Vechiato et al, 1997;Vieira, 1988;Ferreira et al, 2019).…”

Transmission potential of Colletotrichum lindemuthianum (race 65) in association with bean seeds under controlled conditions

2020

View full text Add to dashboard Cite

Anthracnose, caused by Colletotrichum lindemuthianum, is one of the main diseases affecting common bean in Brazil, and field losses can reach 100%. Transmission of this pathogen from seeds to seedlings/plants may vary according to environmental conditions and initial inoculum levels, among other factors. The aim of this study was to quantify the transmission rate of C. lindemuthianum, race 65, from infected bean seeds to seedlings/plants under controlled conditions. Seed inoculation was performed by the water conditioning technique in order to obtain seeds with different inoculum potentials as a result of the exposure time of the seeds to the fungus in pure culture, with the potentials denominated P0, P36, P72, P108, and P144. Inoculated and non-inoculated seeds were individually sown and kept in growth chambers under two temperatures, 20 and 26 °C, for a period of 28 days. There was transmission of the pathogen in both asymptomatic and symptomatic plants. The highest total transmission rate (92%) occurred in plants originating from seeds exposed for 144 hours to the fungus at 20 °C.
