| Alfalfa cultivar Crioula (Medicago sativa cv. Crioula) is grown in South Brazil and only a few studies on the plants' boron requirement are available. A greenhouse experiment was carried out with alfalfa to measure boron acquisition, production and distribution in the plant; data on critical level and production potentials were recorded. Plants were grown in ground quartz added with 1 L of solution, with the following boron rates: 0, 0.0625, 0.125, 0.25, 0.50, 1.00, and 2.00 mg L-1. Plants were harvested at 46 days of growth. Forage dry mass was increased by boron supply and dry matter accumulation was considerably low in control. Boron concentration in the leaves was higher than in the stems or roots. Boron utilization from the external solution reached... |

| Alfalfa weevil (Hypera postica Gyllenhal.) control is traditionally based on the use of chemical insecticides. Due to the side effects of these compounds, there are many motivations for the use of integrated control methods, which may include the use of biopesticides (microbial and botanical). The result of the effect of seven doses of the tested biopesticides (500, 1000, 1500, 2000, 2500, 3000 and 3500 ppm) under laboratory conditions indicated that the insecticides Azadiractin® (1859.971 ppm) and Biobit® (2000.57 ppm) were of the highest, while Basiokara® (3178.697 ppm) and Naturalis® (2973.246 ppm) were of the lowest lethality. Field experiments were carried out based on randomized complete block design with 10 treatments and 4 replications. The... |

| ABSTRACT Foliar diseases impose severe restrictions on the persistence and productivity of Medicago sativa, both of which may be increased by developing disease resistant and more competitive genotypes that can improve pasture quality. We found Curvularia geniculata as the principal alfalfa foliar pathogen in the Brazilian state of Rio Grande do Sul (RS). Growth chamber experiments evaluated the resistance of alfalfa genotypes ‘E1C4’, ‘CPPSul’, ‘ABT 805’ and ‘CUF-101’ to C. geniculata as compared the control ‘Crioula’ genotype. These genotypes were also evaluated in field trials at a sea level site in Eldorado do Sul in central RS and at two sites £200 m above sea level, one in Bagé municipality in south west RS and the other at a farm near the town of... |
