“…Furthermore, mean incidence values did not differ significantly among the various treatments. Similarly, Boechat et al (2014), using spectral analysis, also did not detect white mold within the same DAP range and suggested that crop phase or the residual effects of previous crop management practices could explain the lack of white mold.…”

The aim of this work was to study the effect of fungicides and biological agents on the control of white mold (Sclerotinia sclerotiorum) in common beans (cv. Pérola). Nine treatments were applied in six blocks (54 experimental units) using a randomized block design (RBD). The treatments were: T1 (control); T2, Bacillus subtilis strain QST 713 (4 L / ha); T3, B. subtilis strain QST 713 (4L / ha); T4, B. subtilis strain QST 713 (2 L / h); T5, B. subtilis strain QST 713 trifloxystrobin + prothioconazole (4 L / ha, 0.5 L / ha); T6, B. subtilis strain QST 713 trifloxystrobin + prothioconazole (2 L / ha, 0.5 L / ha); T7, B. subtilis strain QST 713 trifloxystrobin + prothioconazole, fluazinam (2 L / ha, 0.5 L / ha, 1 L / ha); T8trifloxystrobin + prothioconazole, fluazinam (0.5 L / ha, 1L / ha); T9-Trichoderma harzianum, difenoconazole and azoxystrobin fluazinam + (1.5 L / ha, 0.5 L / ha, 1 L / ha). White mold (WM) incidence was evaluated at 39 days after planting (DAP), with subsequent evaluations at 39, 46, 53, 60, 67 and 74 DAP. Average yield from T5, T6, T7 and T8 was statistically higher than in the other treatments and consequently, treatments T7, T8 and T9 had the lowest mean area under disease progress curve values. The combined chemical and biological treatment was an effective white mold management strategy that increased yield and decreased disease incidence in common beans.

“…However, Rio Grande do Sul also stands out in the national scenario, with a yield of 1,926 kg ha -1 year -1 , because of its better technology (IBGE 2015). The low crop yield is the result of several factors, such as the lack of adequate technology (Gomes et al 2016), absence of specific soil fertilization programs (Alves et al 2008) and presence of pests and diseases (Garcia & Romeiro 2011, Boechat et al 2014, Silva et al 2014. Nematodes, especially the root-knot ones, are responsible for high production losses in several crops.…”

Lima bean is one of the most popular leguminous plants in northeastern Brazil, with a strong socioeconomic influence on the regional communities. However, the low yield related to biotic and abiotic factors limits the increase in production. Among the biological agents, root-knot nematodes compromise its vegetative and productive development. In order to select genotypes resistant to Meloidogyne javanica, an experiment was carried out in a greenhouse and in a laboratory, in a completely randomized design, with fifteen lima bean accessions and five replicates. The reaction of lima bean accessions was evaluated through the infectivity and reproduction of M. javanica, as well as the main agronomic traits of the crop. A variation was observed in the resistance level among the accessions, with Lavandeira preta, Orelha de vó and Fava cearense being rated as very resistant, while Lavandeira vermelha was slightly resistant and the remaining accessions were all rated as susceptible.

“…Além dos fatores citados, as doenças destacam-se como um dos mais importantes na diminuição da produtividade do feijoeiro especialmente as causadas por fungos de solo, que podem causar prejuízos severos, com diminuição das qualidades fisiológica, nutricional e sanitária do produto colhido, afetando o preço e sua comercialização (BOECHAT et al, 2014).…”

O feijão-caupi (Vigna unguiculata L.) apesar de ter potencial para ser implantado em grandes áreas, sendo realizado basicamente por pequenos agricultores, apresenta baixa produtividade devido há diversos fatores, como as doenças radiculares que são as maiores causadoras de reduções de produtividade em campo. Portanto, a presente revisão tem como objetivo de explanar a importância do controle biológico sob a murcha de fusarium na cultura do feijão caupi. Visto que o Fusarium oxysporum f. sp. phaseoli penetra o sistema radicular, causando o amarelecimento e a senescência prematura das folhas situadas no terço inferior da planta, reduzindo a produtividade. O Trichoderma spp. têm sido muito utilizado como alternativa ao uso de produtos químicos, sendo considerado de grande importância econômica para a agricultura, capaz de atuar como agente de controle da murcha de fusário provocada por Fusarium oxysporum f. sp. phaseoli e induzir resistência nas plantas, além de influenciar positivamente na germinação de sementes, no desenvolvimento e rendimento da cultura do feijoeiro devido à produção de substâncias promotoras de crescimento e melhoria na nutrição das plantas, principalmente pela solubilização do fósforo.
