| El mango es unos de los frutos más consumidos mundialmente y uno de los cultivos más importantes en nuestro país. Las plagas representan un problema importante para este cultivo en Arcelia, en la región de la Tierra Caliente, Guerrero, México; las plagas principales son trips y ácaros, por tal motivo fueron probados los efectos de los plaguicidas imidacloprid, spinosad, azufre y aceite mineral para observar su efecto en la poblaciones de plagas, así como en la calidad del fruto, tratando de desarrollar un método basado en umbrales de de acción de plagas. De acuerdo con lo observado durante los muestreos podemos considerar a Frankliniella invasor Sakimura como el trips que puede causar daño severo por haberse presentado en poblaciones altas, pero también se... |

| ABSTRACT Grass weeds are common in summer crops and strongly decreases the grain yield of the common bean crop. The time of herbicide application influences the variability of environmental conditions and affects the product performance. The objectives of this work were to identify the time of fluazifop-p-butyl (fluazifop) application which gives best grass weed control in the common bean crop and to elucidate the environmental variables most important for the efficacy of this herbicide. Field experiments were conducted involving five application times (2 a.m., 6 a.m., 11 a.m., 4 p.m. and 9 p.m.) and five doses of fluazifop (80, 110, 140, 170 and 200 g ha-1), with additional no-herbicide control. At the time of the herbicide application it was determined... |

| Abstract Different application frequencies of metalaxyl + mancozeb were evaluated to control downy mildew in vine plants ‘BRS Vitória’ in two experiments conducted in Jales, São Paulo, one in the production cycle and another in branches formation cycle. In experimental design of randomized blocks, five treatments were compared (1- two weekly applications; 2- one weekly application; 3- one application every 14 days; 4- one application every 21 days; 5- applications after sporulation) with four replications, each plot with three plants. According to the analysis of the area under the disease progress curve (AUDPC), in both experiments, there were statistically significant differences between the disease control levels provided by the different treatments (P... |

| ABSTRACT Ryegrass is a weed of annual cycle that is present in winter crops, in orchards and vineyards of the South region of Brazil. The species is normally controlled by the glyphosate herbicide, but the continuous use of this product caused the selection of resistant biotypes. The use of ACCase inhibitor herbicides is the main alternative for the control of this species, but it has not been satisfactory in some places, thus causing suspicion of resistance to this action mechanism. Thus, the objective of this paper was to evaluate the occurrence and geographic distribution of ryegrass biotypes that are resistant to the clethodim herbicide in the state of Rio Grande do Sul. For that, seeds of ryegrass plants that survived the application of clethodim were... |

| ABSTRACT The study aimed to evaluate the growth and development of biotypes of Digitaria insularis susceptible and resistant to glyphosate. Samples of biotypes were collected in Western Paraná in Cascavel, one susceptible (24o57'29.06" S and 53o30'23.73" W) and one resistant (24o54'54.99" S and 53o30'08.55" W; with Resistance Factor of 2.96). The experiment was arranged in a completely randomized design with four replications. The treatments consisted of different plant collection timings, carried out at regular intervals of 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105 and 112 days after emergence. The growth curve of susceptible and resistant biotypes were similar; however, the susceptible biotypes accumulated more leaf dry mass, while the... |
