“…This study also stated that the population dynamics of nematodes are dependent on soil chemical characteristics. Similarly, Pedrosa et al [46] found a decrease in the number of eggs and juveniles of gall nematodes with an increase in the rate of vinasse added to cane.…”

Vinasse is not only effectively used in pest control but also creates a conducive environment for the growth of antagonistic microorganisms. Thus, this study aimed to evaluate the potential of vinasse applied via soil for the management of root-knot nematodes in soybean culture. The experimental design was entirely random, in a factorial scheme (2 × 6), consisting of two species of nematodes, Meloidogyne incognita and M. javanica, under vinasse application at five concentrations (20, 40, 60, 80, and 100%) and one control (water), with five repetitions. Soybean plants Intacta cv. M-Soy 8644 IPRO were inoculated with 4000 eggs/juveniles of each species separately. At 60 days after the first application of vinasse, evaluations of parasitism and agronomic characteristics in soybean were performed. Stillage resulted in the highest average values for root volume and root fresh mass in plants inoculated with M. incognita, showing respective increases of 24.33% and 14.92% compared to plants inoculated with M. javanica. However, concentrations exceeding 60% had a detrimental effect on all agronomic variables of soybean. For parasitism, an interaction among the factors was observed, with a significant effect (p < 0.01) for most of the evaluated variables, except for the number of eggs in the soil. The concentration equivalent to 60% vinasse promoted a sharp reduction in parasitism for the two nematode species, making reproduction on plant roots unfeasible.

“…Vinasse is already known to affect the life cycle and reproduction of phytoparasitic nematodes. Two species of phytopathogenic nematodes, Meloidogyne incognita (Kofoid & White) and Meloidogyne javanica (Treub), were exposed to soils containing different concentrations of vinasse [33]. After 90 days, there was a drastic decrease in reproductive activity and in the number of eggs for both due to the increased concentrations, especially for M. incognita, which was almost completely inhibited.…”

An Assessment of Steinernema rarum as a Biocontrol Agent in Sugarcane with Focus on Sphenophorus levis, Host-Finding Ability, Compatibility with Vinasse and Field Efficacy

In Brazil, countless insect species attack and damage sugarcane (Saccharum officinarum L.), which is an extremely important crop since it is planted on more than 10 million hectares. Among these insects, the sugarcane billbug, Sphenophorus levis (Coleoptera: Curculionidae), is of great importance as the larvae open tunnels in the rhizome of the plant, causing high damage and losses. This insect is attracted mainly to vinasse, which is the liquid fraction generated from the alcohol production and discarded onto the sugarcane fields for fertigation. Toward a novel control method for S. levis, the native entomopathogenic nematode Steinernema rarum (Pam 25) was compared with S. carpocapsae (IL 1) and Heterorhabditis bacteriophora (HBEN01) in respect to their ability to search for larvae of two insect hosts (Galleria mellonella and S. levis) within the cane rhizome. The selected nematode S. rarum was also assessed for rate effects, its survival in vinasse and field efficacy to control sugarcane pests S. levis, Hyponeuma taltula (Lepidoptera, Erebidae) and Leucothyreus alvarengai (Coleoptera: Melolonthidae). Steinernema rarum exhibited superior virulence to G. mellonella and S. levis larvae inserted into the cane rhizomes (75–78% mortality) compared to S. carpocapsae (30–53%) and H. bacteriophora (18–28%). Vinasse affected S. rarum when infective juveniles were suspended in the liquid compost for more than 6 h but did not affect the nematode when kept on the straw and soil treated with the compost. Steinernema rarum tested at 1–3 × 108 infective juveniles/ha on the sugarcane field caused 74.1, 56.3 and 50.6% control of S. levis, L. alvarengai and H. taltula, respectively.

“…Assim, a presença da Crotalaria juncea na produção de cana de açúcar oferece uma abordagem promissora para o manejo integrado de pragas e doenças, contribuindo para a sustentabilidade da cultura e oferecendo alternativas ecológicas e eficazes para o controle de pragas e doenças no contexto agrícola (Pedrosa, 2021).…”

A pesquisa detalhada sobre a interação entre Crotalaria juncea e cana-de-açúcar revelou benefícios amplos para a sustentabilidade agrícola, incluindo a condição do solo, redução de custos e impactos ambientais positivos. O estudo visou analisar essa interação, compreendendo sua eficácia na promoção da saúde do solo e promover melhores práticas de agricultura. Além disso, examinou os benefícios econômicos, como a diminuição dos gastos com fertilizantes nitrogenados, e identificou modelos econômicos para encorajar os agricultores a adotarem essas práticas. Impactos ambientais favoráveis, como a redução das emissões de gases de efeito estufa e a conservação da biodiversidade. A resistência a pragas e doenças, bem como a redução da dependência de pesticidas na cana-de-açúcar, foram destacadas. Em conclusão, o estudo não só demonstra os benefícios da interação entre Crotalaria juncea e cana-de-açúcar, mas também ressalta a importância de uma abordagem integrada e colaborativa. Essa pesquisa oferece uma contribuição para pesquisadores, agricultores e formuladores de políticas, impulsionando práticas agrícolas mais sustentáveis.
