Coffee ringspot virus (CoRSV), transmitted by the tenuipalpid mite Brevipalpus phoenicis, has been reported in many parts of Brazil and recently, in Costa Rica. Particularly in the Southern region of tne State of Minas Gerais, it has been found in high incidence inducing some losses. CoRSV has particle morphology and cytopathic effect similar to Orchid fleck virus (OFV), transmitted by B. californicus. Systemic infection of some hosts as Chenopodium quinoa and Tetragonia expansa obtained by growing them in higher temperatures, permitted a partial purification of CoRSV, using a modified Chang et al. protocol for OFV, which yield rodlike particles with one round end, 45 nm x 100-140 nm, with a 25 nm axial channel and cross striations with a pitch of 4 nm. Agarose gel electrophoresis of the RNA extracted from these preparations produced 2 bands of 6,000 and 6,400 nts. Injection of semi-purified preparations into rabbit produced an antiserum. Comparative assays with anti-CoRSV and anti-OFV (Kondo et al., 1995) sera, previously adsorbed, with indirect ELISA, demonstrated highly specific reactions for homologous viruses, but no detectable cross-reaction. In situ immunocytochemistry resulted in significant labeling on the nuclear viroplasm present in CoRSV- or OFV-infected leaf cells in homologous reaction and slight labeling in heterologous reactions using anti-CoRSV and anti-OFV sera. |

The maize intercropped with legume cover crops are used at low technological agriculture, due it?s potential to suppress weeds, recycle nutrients, and cover the soil. Weeds suppression it is important due to its competition effect on the commercial crops. The nutrient recycling it is important due to the low fertilizer use on low technological agriculture. The soil cover it is important to prevent the erosion and reduce the nutrients leaching. All those positive effects can be influenced due to the cultivated species on the consortium. This study aimed to evaluate the soil coverage, the phytomass production and, the accumulation of nutrients by plants in a maize and legume cover crops intercropping system. The experiment consisted of rustic maize ?Caiano de Sobrália? variety, intercropped with Brazilian velvet bean, black mucuna, lablab-bean and pigeon pea; a control treatment (sole maize culture) was added. The maize was sown on the experiment; 64 DAE, the legumes were sowed. The soil cover rates were evaluated at 0, 64, 84, 120, and 144 DAE. The corn grains were harvested at 120 DAE, resulting in the corn grain yields. The remaining portion of maize and entire legume cover crop plants were sampled at 144 DAE, when the accumulation of dry mass and nutrient were measured. The consortium system did not affect the corn grains yield and, the soil cover rate provided by maize plants. The black mucuna had the greatest weeds suppression and, nutrient accumulation among the legumes cover crops evaluated.
