Brazil is the world's largest producer of passion fruit, a perishable fruit with reduced post-harvest shelf life, which limits its commercialization. For sweet Passiflora alata, there little information about postharvest conservation and life under different storage conditions. Thus, objective present study was to determine P. alata fruits packed on styrofoam trays rapped 10 μm PVC film HDPE 30 thick, coated 18% carnauba wax without any packaging; stored ambient conditions (25 °C 70%...
Genótipos de mamoeiro (Carica papaya) ('NT Red', 'Golden', 'Baixinho St. Amália', 'Sunrise Solo', 'Cross Paris', 'Tailândia Verde', Roxo', Roxão', 'Sekati' e 'Tainung-1') foram avaliados quanto à reação varíola (Asperisporium caricae) podridão-do-pé (Phytophthora palmivora). O estudo foi conduzido em uma área com plantas naturalmente infectadas ambos os patógenos sob telado utilizando solo infestado P. palmivora. A severidade avaliada usando-se escala, 1 (0-3% da superfície coberta por...
Two of the most common post harvest papaya (Carica papaya) pathogens are Colletotrichum gloeosporioides (anthracnose) and Phoma caricae papayae (stem rot). isolates C. (Cg 32 Cg 78) one P. (P 725) were inoculated on fruits both 'Solo' 'Formosa' groups in two different types trials: (1) Fruits submerged water at 48°C for 10, 15, 20, 25 30 min; (2) 44, 46, 48 or 50°C 20 min. Afterwards, cooled down (13±1°C/20 min) stored 14 days a cold chamber (13±1°C R.H. 85-100%). A physical-chemical...
ABSTRACT It has been demonstrated that for a nonpathogenic, leaf-associated bacterium, effectiveness in the control of bacterial speck tomato is correlated with similarity nutritional needs nonpathogenic bacterium and pathogen Pseudomonas syringae pv. tomato. This relationship was investigated further this study by using Xanthomonas campestris vesicatoria, causal agent spot tomato, collection bacteria isolated from foliage. The effects inoculation plants one 34 prior to X. vesicatoria were...
O controle da varíola do mamoeiro é necessário; portanto, propôs-se, neste estudo, avaliar o efeito de aplicações foliares fosfitos (K, Ca, Mg e Cu) sobre a doença. Dois fungicida Fosetyl-Al foram testados em condições campo, com plantas naturalmente infectadas pelo patógeno. Dez sob telado também por A. caricae. Tanto no experimento campo quanto telado, os tratamentos contendo fosfito reduziram severidade
O controle da podridão-do-pé (Phytophthora palmivora) do mamoeiro (Carica papaya) é essencial para reduzir perdas e aumentar a produtividade dos plantios. Sete fosfitos foram avaliados em plântulas (~10cm de altura) cultivar 'Tailândia Roxão'. Experimentos conduzidos com os seguintes objetivos: determinar melhor forma aplicação fosfito (pulverização ou rega); o período prévio à inoculação patógeno fosfito; quantidade aplicações efeito diferentes sobre doença. Os resultados testes mostraram...
Papaya (Carica papaya) foot rot (Phytophthora palmivora) reduction due to phosphites This study showed that two weekly sprays of phosphite [A (40 % P 2 O 5 + 20 K O, 150 mL commercial product.hL -1 ), B 250 mL), C (10 6 Ca, 400 D (20 200 E Mg, F (30 175 G mL) ] for three consecutive weeks before pathogen inoculation reduced disease severity.
A podridão vermelha da raiz de soja vem crescendo em importância, a cada ano, no Brasil, com aumento substancial participação nas perdas produtividade. Na região dos Cerrados, são escassos os dados campo sobre reação cultivares à doença. Assim, este trabalho teve como objetivo caracterização, campo, uma série genótipos soja, quanto resistência raiz, solos naturalmente infestados. Foram testados 71 sendo 16 do ciclo maturação precoce, 28 médio e 27 tardio, quatro localidades, entorno Distrito...
Spontaneous plants of Ipomoea acuminata ("morning glory") exhibiting white rust pustules were found in a field crop area Planaltina, DF, the fall season 2010 and disease causal agent was identified as Albugo ipomoea-panduratae (Oomycota). No reports association between A. I. known Brazil previously to 2010. A reference specimen deposited at University Brasilia Mycological Reference Collection.
Elephant grass is a major forage crop, widely used to feed dairy herds in Brazil. In April 2023, 200 seeds of cv. BRS Capileto (Pennisetum purpureum × Pennisetum glaucum), commercial elephant hybrid developed by Embrapa, were collected from seed crop the municipality Coronel Pacheco, Minas Gerais, The at harvest for scheduled phytosanitary evaluation. Seeds divided into four groups fifty. Each group was disinfected submerging 1% NaClO solution, three minutes and then, subsequently, washed...
Soybean (Glycine max L.) is the most widely cultivated crop in world and an important commodity. Besides its main role human nutrition, this grain also used animal feed production of biofuels, among other purposes. Due to these factors, soybean became global economy exported agricultural product from Brazil. Fungal diseases are limiting factors on production; sudden death syndrome, caused by Fusarium spp., has been responsible for severe losses Four species can be considered causal...
