“…The Nem-Out™ stood out among the most efficient products in the control of both nematodes; these results corroborate the study by Oliveira, Chaves, Vieira, Silva, and Rodrigues (2011), who have found reduced Pratylenchus spp. population density in sugarcane grown under greenhouse conditions.…”

Nematodes stand out among the main soya bean yield limiting factors due to limitations in the main control methods, mainly when they are applied alone. Given the need of finding new control techniques, the aim of this study was to assess the efficiency of products based on biological control agents and on nutrients or products showing potential to induce resistance for Pratylenchus brachyurus and Meloidogyne javanica control in soya bean plants. The experiments were conducted in a greenhouse; nine treatments with six repetitions for each nematode were assessed in two distinct periods. Overall, all treatments have shown potential to control the nematodes in at least one experiment, mainly the ones containing biological control agents (Trichoderma and Bacillus). The vegetative development results were inconclusive; however, some products have shown potential to improve the growth of infected plants.

“…Na tabela 2 encontra-se os resultados numéricos para comprimento de raiz e número de nematoides (não houve diferenças significativas entre os produtos biológicos utilizados); e os resultados médios para o tamanho de planta e severidade. A não significância encontrada para estas variáveis no presente estudo corroboram com estudos realizados por Oliveira et al (2011) em cana-de-açúcar, os quais objetivando o controle de nematoides do gênero Pratylenchus com os produtos carbofuran, fipronil, P. lilacinus, thiamethoxam e a interação destes, observaram que os tratamentos não diferiram entre si. Os autores concluíram tais resultados foram atribuídos ao fato de as plantas terem sido colhidas ainda jovens e devido o experimento ter sido conduzido em vasos.…”

A cultura da soja possui grande importância para a economia brasileira e pode enfrentar entraves dos fatores bióticos e abióticos em sua produção, sendo os nematoides expoentes na redução da produtividade desta cultura. Desse modo, este trabalho teve como objetivo avaliar o efeito de produtos biológicos para o controle de Pratylenchus brachyurus na cultura da soja. O experimento foi realizado na casa de vegetação e no Laboratório de Fitopatologia e Nematologia do Centro Universitário Católica do Tocantins. O delineamento experimental foi inteiramente casualizado consistindo em cinco tratamentos com diferentes produtos biológicos: T1 – testemunha (sem tratamento), T2 - Presence® (Bacillus subtilis e Bacillus licheniformis), T3 - Votivo Prime® (Bacillus firmus), T4 - Ecotrich® (Trichoderma harzianum) e T5 – Nemat® (Paecilomyces lilacinus) com quatro repetições. Para avaliação da eficiência do controle biológico de nematoides, procedeu-se o tratamento prévio das sementes de soja no momento da semeadura. O tratamento das sementes foi realizado individualmente, adicionando os produtos conforme dosagem estabelecida na recomendação da bula. Aos 30 dias após a inoculação, foram avaliadas a características, comprimento da raiz, tamanho de planta, número de nematoides e severidade. Os produtos utilizados não interferiram no comprimento da raiz e no número de nematoides. O produto T3 – Votivo Prime®, apresentou melhor resultado quando se avalia o comprimento de planta. A severidade foi menor quando se faz uso de algum tipo de produto para controle biológico.

“…In addition, Nem-Out TM was efficient in the management of Pratylenchus spp. in sugarcane, in researches under controlled conditions (Oliveira et al, 2011). One of the factors that may explain the efficiency of Nem-Out TM for nematode control is the presence of bacteria of the genus Bacillus, which have been shown to have multiple mechanisms of action, including the production of metabolites toxic to nematodes, competition for nutrients in the rhizosphere, changes in root exudates released by the plant and the ability to induce plant resistance to pathogens (Oliveira et al, 2014;Yu et al, 2015;Zheng et al, 2016;Govindasamy et al, 2017).…”

Root-knot nematodes limit lettuce crop productivity. Efficient control is achieved through integrated management, and research about the efficiency of new products for nutrition and biological control is required. Thus, the objective of this study was to evaluate the effect of fertilizers, applied alone or in combination with microorganisms based product on the control of Meloidogyne javanica in lettuce. In the first research (research 1), conducted at two different periods, the products Agro-Mos®, Soil-SetTM and Copper-Crop® applied on shoots were evaluated; in research 2, the same products were applied isolated on shoots or associated to NemOutTM (Bacillus licheniformis, B. subtilis and Trichoderma longibrachiatum) applied to the soil. In research 1, the fertilizers Agro-Mos®, Soil-SetTM and Copper-Crop® applied alone promoted reduction in reproduction of M. javanica ranging from 31 to 75%, 36 to 79%, and 71 to 75%, respectively. The effect on plant development was variable, obtaining better results of fresh shoot mass applying Copper-Crop®. The combination of products did not have an additional effect on the control of the nematode, on the contrary, in general the products had antagonistic action. However, fertilizers and biological control applied isolated were efficient for nematode control.
