“…Germinação (%) provenientes de sementes tratadas quimicamente submetidas ao teste de germinação nos padrões das Regras para Análise de Sementes (RAS). (Pereira et al, 2019). Ainda para cultura do trigo, constatou-se sob o uso da piraclostrobina, maior atividade antioxidante e menor síntese de etileno (Grossman et al, 1999).…”

Resultante de uma mutação espontânea do milho convencional, o milho doce possui elevado potencial de produtividade no Brasil, sendo considerado alternativa rentável aos produtores, e o colocando em ascensão. Contudo, a escassez de informações técnicas reduz este avanço. A fim de analisar a viabilidade da semente, o teste de germinação em laboratório é utilizado para comparar a qualidade entre lotes e estimar seu desempenho para semeadura em campo. Suscetível ao ataque por fungos e insetos, devido sua composição e características morfológicas, o tratamento de sementes de milho doce com produtos químicos é uma opção viável para reduzir possíveis perdas de qualidade. Desse modo, analisou-se a incidência de fungos fitopatogênicos, bem como sua redução devido ao uso de fungicidas no TS. Porém, para o teste de germinação, pode-se encontrar antagonismo do valor obtido para sementes tratadas, relacionado ao desempenho destas sementes a campo. A fim de elucidar e corrigir estes erros realizou-se um estudo das condições que os propiciam e definiram-se soluções para o problema, adequando às metodologias utilizadas na realização dos testes de germinação.

“…The study of this bibliographical review was carried out between the months of October and November of this year, in which l it includes the consultation of scientific publications that allow describing the processes, products used and equipment in seed treatment. According to (PEREIRA et al, 2019), when preparing a literature review, the results of some discovery, experience carried out, describing a case, describing some phenomenon that have occurred are being reported.…”

“…With regard to innovation in seed treatment, especially industrial seed treatment, companies have been working to create new technologies that are more productive and at the same time more sustainable, especially designed to meet the needs of farmers (PEDRINI et al, 2017). Both in seed treatment and in combating pest control (insects, nematodes, weeds, diseases, among others), making products and pesticides work together to assist in integrated pest management practices, helping to increase production and crop yield (PEREIRA et al, 2019).…”

“…As for the forms of seed treatment, there are two forms of seed treatment, namely: on-farm, carried out by the producer shortly before sowing, or industrial seed treatment (TSI), where the latter becomes more efficient, as it gives to the seed a uniform dosage of the product to be used, carried out by a trained professional, which consequently allows for a more uniform, healthy and productive crop (PEREIRA et al, 2019).…”

Seed treatment is extremely important and beneficial for all crops, which aims to eliminate and control fungi, insects and other pests that attack seeds, seedlings and plants. For this, it is necessary to use new technologies and agricultural equipment that help in the treatment of these seeds, making the producer more profitable. This literary review aims to describe different types of seed treatments and agricultural equipment that can help in this process. This study took place between October and November 2022 and used different works as a basis to develop this review, in which it can be seen that the demand for seed treatment in Brazil has increased in relation to the use of fungicides and application technologies and equipment. , where it can be concluded that seed treatment is constantly evolving, both with regard to seed treatment equipment and the chemical and biological products used.

Seed Treatment With Trichoderma and Chemicals to Improve Physiological and Sanitary Quality of Wheat Cultivars1

et al. 2021

Seed treatment with fungi of the genus Trichoderma spp. provides several benefits, including plant growth promotion, stress tolerance, and pathogenic fungi control. Moreover, to avoid inadequate doses and unnecessary costs, these treatments must be applied in proper amounts. However, no study has evaluated their applicability in wheat seeds. This study aimed to determine the most efficient dose of Trichoderma-based products applied as a seed treatment for improving the physiological and sanitary quality of the wheat cultivars TBIO ‘Toruk’ and TBIO ‘Sossego’, besides comparing the performance of biological and chemical agents. Two biological treatments (Trichoderma asperellum SF 04 and Trichoderma harzianum IBLF006) were applied at 0 (control), 5 × 10 11 , 1 × 10 12 , 1.5 × 10 12 , and 2 × 10 12 colony-forming units (CFU) 100 kg–1 seed. Two chemical treatments (carboxin + thiram and pyraclostrobin + thiophanate-methyl + fipronil) were applied at the manufacturers’ recommended doses. Seed germination, shoot and root lengths, seedling dry matter, and sanitary quality were analyzed under laboratory conditions, while seedling emergence, shoot length, and shoot dry matter were analyzed under greenhouse conditions. The optimal dose for wheat seed treatment with T. asperellum SF 04 and T. harzianum IBLF006 was 2 × 10 12 CFU 100 kg–1 seed. When comparing biological and chemical products, our findings indicate that both options are adequate for managing wheat diseases and providing seedling growth via seed treatment.
