| La presente investigación evaluó los efectos de la interacción entre el bicarbonato de potasio (KHCO3), el fungicida iprodione y el hongo Trichoderma viride, para controlar el crecimiento y desarrollo de Sclerotinia sclerotiorum. Para ello, este trabajo fue dividido en tres capítulos experimentales. El primer capítulo evaluó el potencial antagónico de cuatro hongos filamentosos (Trichoderma viride, Phanerochaete chrysosporium, Trametes sp. y Trametes versicolor) contra Sclerotinia sclerotiorum, mediante confrontamientos in vitro y producción de enzimas como amilasas, lipasas, pectinasas, proteasas y celulasas. De los cuatro hongos T. viride tuvo mejor potencial antagónico. El segundo capítulo evaluó el crecimiento y desarrollo de Sclerotinia sclerotiorum... |

| Se estudió el progreso temporal de epidemias de antracnosis (C. gloeosporioides) y cenicilla (O. mangiferae) en dos huertos de mango (Mangifera indica) sujetos a programa de aspersión periódica de fungicidas de distinto grupo químico, modo de acción, combinación (rotación) y secuencia de aplicación, en concordancia con el desarrollo fenológico de tres flujos florales. El experimento se realizó en el huerto comercial “Las Tunas” en la región del trópico subhúmedo (Costa Grande) de Guerrero, México, durante el ciclo productivo 2010-2011. Las escalas fenológicas utilizadas permitieron identificar la floración plena, amarre inicial (3-5mm Ø) y frutos tamaño (8-15mm Ø) como etapas críticas de infección. El inicio de las epidemias se registró 23-30 días... |

| Este trabalho objetivou avaliar o efeito de dois tipos de embalagens e do tratamento fungicida na qualidade de sementes de soja armazenadas. Sementes de soja das cultivares FT-Estrela e MT/BR 51 (Xingu), tratadas e não tratadas com os fungicidas tiofanato metílico, tolylfluanid, carbendazin e benomyl, foram armazenadas (em sacos de papel e em sacos de polietileno) em armazéns convencionais em Ponta Porã, MS e Rondonópolis, MT, respectivamente. Uma máquina da marca Amazone Transmix foi utilizada para fazer o tratamento. A cada 60 dias foram realizadas avaliações dos seguintes parâmetros: umidade das sementes, sanidade de sementes (blotter test), germinação padrão, vigor no tetrazólio, emergência em areia e emergência a campo. Não foi observado efeito... |

| ABSTRACT: The use of pesticide mixtures constitutes a relatively common practice in rice crops. Thus, the aim of this work was to evaluate the physicochemical interaction among different pesticide tank mixes for use in paddy field rice. The study has followed technical standards specified in ABNT [Associação Brasileira de Normas Técnicas (Brazilian National Standards Organization)] NBR [Norma Brasileira Regulamentadora (Brazilian Regulatory Standard)] NBR 13875:2014 for the assessment of physicochemical compatibility by means of a dynamic technique. Treatments consisted of mixtures of 12 pesticides, which constituted 16 treatments, six of which are composed by mixing herbicides, six by mixing herbicide and insecticide, one by mixing fungicides, and three... |

| Enhanced degradation of the fungicide metalaxyl was investigated in two soils: a gley humic (GH) and a Dark Red Latosol (LE), collected at sites never exposed to the fungicide. The soil samples were treated with successive applications of metalaxyl as a commercial formulation and 14C-metalaxyl in laboratory. Metalaxyl biodegradation was analyzed during 63 days by means of radiometric techniques to verify biomineralization and degradation product formation from the applied 14C-metalaxyl. Although biomineralization (maximum of 14 and 8% in the GH and LE soils, respectively), and partial degradation (about 32 and 48%, respectively) were detected in both soils, enhanced degradation was verified only in the GH soil. Results proved that metalaxyl behaves... |

| ABSTRACT Due to the socioeconomic importance of common bean in Brazil, studies that allow establishing favorable conditions for not compromising the crop with white mold, in view of the enormous damages caused by this fungus, become vital to Brazilian agriculture. Therefore, the aim of this study was to evaluate the incidence and severity of white mold in common bean (Phaseolus vulgaris L.), cultivar ‘Madrepérola’, subjected to different irrigation intervals, planting densities and fungicide application. The research was conducted in Viçosa-MG, Brazil, in the years 2011 and 2012. The statistical analysis used the split-split-plot scheme. The fungicide applications (with or without fungicide) were allocated to plots, the irrigation intervals (3, 6, 9 and 12... |

| Abstract This study aimed to establish an alternative treatment for post-harvest storage of Papaya (Carica papaya L.), var “Tainung 1” and to control major diseases at this stage. Two storage place were evaluated (room temperature and cold room); Six treatments (Control, Samurai 40ml/20l water, Serenade® 40ml/20l water, Sanatizer EUPROOFF® 10ml/20l water, EUPROOFF® + Serenade® + Samurai, Serenade® + Samurai), five storage periods (0, 3, 6, 9 and 12 days) and three seasons (December, January and February). Fruit weight loss (FWL), color index, number and size of lesions were evaluated and used to calculate the disease incidence and average of disease incidence. The FWL and index color of fruits were more affected by monthly variation than the treatments,... |
