“…Assim, constata-se que o tratamento de sementes proporcionou incrementos na produtividade de grãos do arroz de 2606 para 3352 kg ha -1 no terceiro experimento e de 1045 para 1701 kg ha -1 no quarto experimento (Tabela 4). Da mesma forma, Pinheiro et al (2016aPinheiro et al ( , 2016b, 2016c e 2016d) mostraram que o tratamento de sementes foi eficaz para proporcionar incrementos na produtividade de grãos de arroz de terras altas. Os autores atribuíram esse resultado à redução dos danos causados ao arroz por insetos do solo.…”

“…O efeito da pressão de compactação sobre o sulco de plantio no controle de insetos-praga pode ser uma das causas da maior produtividade do arroz com o incremento dessa pressão. A compactação sobre o sulco de plantio, além de melhorar o contato do solo com as sementes de arroz, permitindo que elas absorvam água mais cedo e germinem mais rapidamente (Silva, 2006;Pinheiro et al, 2016b,c), também reduz o ataque de cupins no arroz de terras altas cultivado em plantio direto (Pinheiro et al, 2016a), sendo o benefício dessa prática reforçado quando associado ao tratamento de sementes com inseticidas Pinheiro et al, 2016a Pinheiro et al, v.11, n.39, p. 6-13 , Dourados, 2018 infestados por insetos na Austrália. Esses autores atribuíram essas respostas ao aumento no suprimento de água do solo e a redução do dano letal às sementes e plântulas causado por uma ampla faixa de espécies de insetos.…”

“…Os cinco países com maior área sob esse sistema são Estados Unidos, Brasil, Argentina, Canadá e Austrália, com 35,6; 31,8; 29,2; 18,3 e 17,7 milhões de hectares, respectivamente (FAO, 2015). https://doi.org/10.30612/agrarian.v11i39.5267 Revista Agrarian ISSN: 1984ISSN: -2538 7 Pinheiro et al, v.11, n.39, p. 6-13 , Dourados, 2018 Embora parte significativa da área de cerca de 50 milhões de hectares ocupada pela agricultura brasileira esteja sob SPD (Nascente & Crusciol, 2012), o arroz de terras altas, produzido somente com águas da chuva, sem irrigação, não tem tido desenvolvimento adequado sob esse sistema (Crusciol et al, 2010;Nascente et al, 2011;Nascente et al, 2013). Assim, é importante desenvolver tecnologias para atingir altas produtividades de arroz no SPD, visando a sustentabilidade da agricultura, aumentando a produção de alimentos e economizando mais água (Farooq et al, 2009).…”

Resumo: Este trabalho objetivou determinar o efeito da compactação sobre o sulco de plantio e do tratamento de sementes na produtividade do arroz de terras altas cultivado sob sistema plantio direto (SPD). Foram conduzidos quatro experimentos, o primeiro e o terceiro em área de pastagem de Urochloa brizantha, o segundo em área de soja e o quarto em área de pastagem de Urochloa decumbens. No primeiro e no segundo foram comparadas três pressões de compactação sobre o sulco de plantio, no delineamento de blocos ao acaso, com seis repetições. No terceiro e no quarto foram comparados três pressões de compactação sobre o sulco de plantio e dois tratamentos de sementes, em blocos ao acaso, esquema fatorial (3x2), com seis repetições no terceiro e 12 no quarto experimento. No primeiro experimento, as pressões de compactação foram 25 kPa, 42 kPa e 228 kPa e, nos outros três, a pressão de 228 kPa foi substituída pela de 340 kPa. Os tratamentos de sementes foram: T0 -sem tratamento e T1 -fipronil + piraclostrobina + tiofanato metílico. A compactação sobre o sulco de plantio até 340 kPa aumentou de forma linear a produtividade do arroz. O tratamento de sementes proporcionou maiores produtividades do arroz cultivado no SPD sobre palhada de braquiária. Com base nos resultados, conclui-se que a compactação sobre o sulco de plantio até 340 kPa e o tratamento de sementes foram importantes práticas para proporcionar incrementos significativos na produtividade de grãos do arroz de terras altas. Palavras-chave: Oryza sativa, plantio direto, palhada de braquiária Abstract: This study aimed to determine the effect of compaction on sowing furrow and seed treatment on grain yield of upland rice cultivated under no-tillage system (NTS). Four experiments were carried out; the first and the third one in Urochloa brizantha pasture area, the second one in soybean area and the fourth one in Urochloa decumbens pasture area. In the first and second experiments, three compaction pressures on the sowing furrow, in the design of randomized blocks with six replications, were compared. In the third and fourth experiments, three compaction pressures on the sowing furrow and two seed treatments, in a randomized block factorial (3x2) with six repetitions in the third one and 12 in the fourth one, were compared. In the first experiment, the compaction pressures were 25 kPa, 42 kPa, and 228 kPa and, in the three others, the pressure of 228 kPa was replaced by 340 kPa. The seed treatments were: T0 -without treatment and T1 -fipronil + pyraclostrobin + thiophanate methyl. The compaction on the sowing furrow up to 340 kPa linearly increased rice grain yield. Seed treatment resulted in higher yields of rice grown in the NTS on Urochloa straw. Based on the results, it was concluded that soil compaction on the sowing furrow up to 340 kPa and seed treatment were important practices to provide significant increases in grain yield of upland rice.

“…Filming is a technology that allows, among other uses, the addition of agrochemicals to seeds without changing their size or shape. For example, polymer composite films have been widely used in the seed industry to enable the identification, differentiation, and traceability of high-value seeds due to different colors, and that improve crop stand provided by better fluidity of seeds in planting (PINHEIRO et al, 2018).…”

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.

“…Several other publications discuss the malicious activity of termites in different regions and different species. In Brazilian savanna termites, for example, Procornitermes araujoi Emerson, 1952, Procornitermes crucifer Silvestri and Syntermes molestus Burmeister, 1839 can lead to total loss in rice production (Pinheiro et al 2016). In yam fields of central Benin, the most damaging termite species are Amitermes evuncifer Silvestri and Trinervitermes oeconomus Tragardh (Loko et al 2016).…”

In this review article, the positive and negative impacts of termites on ecosystems and human activities are examined. Various ecosystem services provided by termites – their importance as a food resource for humans, wildlife and domestic animals – are discussed, along with the use of these insects in scientific research and in folk and traditional medicine. Some insufficiently studied properties of termites (their ability to perceive the radiation of radioactive substances, electric fields and magnetic fields), as well as the use of termites in bionics, are described. Special attention is paid to the use of termite mounds for different purposes (e.g. in mineral deposit searches, in medical applications, as furnaces for copper smelting, for storage of some nuts, as burial sites, for gathering of edible mushrooms of the genus Termitomyces and as fertilizer). Examples of such use in different countries are given. This article reviews the activities of termites as pests of agriculture and forestry, including crops that are most affected, and termites as structural pests (e.g. wooden structures, household furniture, books and museum collections). Examples of termites’ malicious activities in different parts of the world are provided. Information on the invasions of termites is given, and the main areas of expansion of their habitat are described. The economic loss caused by termites in some countries and the world as a whole are presented. The article also lists the most economically important termite species in the world.
