| Abstract: The objective of this work was to evaluate the adaptability of different lettuce (Lactuca sativa) cultivars grown in no-tillage on straw of ruzi grass (Urochloa ruziziensis), as well as its effects on soil temperature and weed control, in successive cultivations in the summer. The treatments were carried out in a randomized complete block design, with four replicates, in a split-plot arrangement (2x4), in which soil management (no-tillage on ruzi grass and convention tillage) was the main plot, and the different crisphead lettuce cultivars (Amanda, Solaris, Vanda, and Vera), the subplots. No difference was observed between cultivars for soil management. No-tillage reduced the soil temperature by up to 3.7°C and weed density by 3.7 times, in... |

| Turnip (Brassica rapa var. rapa L.), beetroot (Beta vulgaris L.) and carrot (Daucus carota L.) are common vegetables in South Africa. The allelopathic potential of aqueous leaf and root extracts of Aloe ferox Mill.- a highly valued medicinal plant- was evaluated against seed germination and seedling growth of the three vegetables in Petri dish experiments. The extracts were tested at concentrations of 2, 4, 6, 8, and 10 mg/mL. Leaf extract concentrations above 4 mg/mL inhibited the germination of all the crops, while the root extract had no significant effect on germination irrespective of concentration. Interestingly, the lowest concentration of leaf extract stimulated root length elongation of beetroot by 31.71%. Other concentrations significantly... |

| The behavior of the fresh fruits and vegetable produce section was evaluated, under the point of view of the consumer, in three types of food retail stores in Campo Grande, Brazilian southeast: a grocery store ("quitanda"), a supermarket, and an open-air market. A quantitative-descriptive survey was conducted with 120 individuals, responsible for purchasing fresh fruit and vegetable produce for their homes. To accomplish that, twelve variables were investigated and adapted from the parameters used in the SERVQUAL model, in which the attributes of the retail outlet are pointed out, such as store hygiene and cleanliness and manner by which produce is displayed; employee training traits, such as courtesy and helpfulness; and quality, price range, and variety... |

| La familia Agromyzidae presenta un gran número de especies reportadas como plagas de cultivos agrícolas. Las especies más dañinas generalmente son polífagas, tiene distribución prácticamente cosmopolita y muestran una alta capacidad de adaptación a nuevas áreas geográficas, lo que representa un grave problema sanitario en los cultivos hortícolas. En este estudio se identificó a los minadores presentes en las hortalizas de mayor importancia para las zonas productoras de los estados de Morelos, Puebla y Veracruz. El estudio se realizó de noviembre de 2009 a marzo de 2011 en los municipios de Tepeaca y Los Reyes de Juárez en el estado de Puebla, en los municipios de Tlayacapan y Yecapixtla en el estado de Morelos y el municipio de Cotaxtla, Veracruz. Se... |

| ABSTRACT Species of the genus Meloidogyne are limiting factors in vegetable crop production. Studies in Brazil about the occurrence of root-knot nematodes in areas of vegetable crop growth have been conducted without using advanced techniques. Using modern techniques, such as biochemical and molecular methods, improves the accuracy of Meloidogyne species identification. The present study characterized species of Meloidogyne in 36 samples associated with vegetable crops using isoenzyme electrophoresis, SCAR markers, and morphological markers, in addition to validating SCAR markers for accurate species identification. The species M. incognita, M. javanica, M. hapla, M. morocciensis, and M. arenaria were identified, with the first two being the most frequent.... |

| Myrothecium roridum and M. verrucaria are two plant pathogenic species causing foliar spots in a large number of cultivated plants. This paper aims to study the causal agents of foliar spots in vegetable crops (sweet pepper, tomato and cucumber), ornamental plants (Spathiphyllum wallisii, Solidago canadensis, Anthurium andreanum, Dieffenbachia amoena) and a solanaceous weed plant (Nicandra physaloides). Most of the isolates were identified as M. roridum; only the isolate 'Myr-02' from S. canadensis was identified as M. verrucaria. All the isolates were pathogenic to their original plant hosts and also to some other plants. Some fungicides were tested in vitro against an isolate of M. roridum and the mycelial growth recorded after seven days. Fungicides... |

| Whiteflies of economic importance are polyphagous, being able to develop on a large number of cultivated and spontaneous plants. We recorded the whitefly species on vegetable and flower crops and the wild plants associated, under greenhouse and field conditions, for two years. We observed two species: Trialeurodes vaporariorum (Westwood) and the Bemisia tabaci complex (Gennadius). T vaporariorum was recorded on 24 plant species (11 families), 12 and 8 of which are new hosts in Argentina and in the world, respectively. The B. tabaci complex was recorded only on flower production systems, on 19 plant species (11 families), 14 and 7 of which are new hosts in Argentina and in the world, respectively. The crops Glycine max (L.) and Chrysanthemum morifolium... |
