| Weed suppression is one of the several benefits achieved by soil incorporation of crop residues and such suppression is believed to be allelopathic in nature. The allelopathic potential of different crop residues: viz. sorghum (Sorghum bicolor [L.] Moench), sunflower (Helianthus annuus L.), brassica (Brassica campestris L.) was evaluated in rice (Oryza sativa L.) and jungle rice (Echinochloa colona [L.] Link). Chopped crop residues were soil-incorporated alone and mixed at 6 g kg-1 soil (12 t ha-1) and compared with a control without residues. Soil incorporation of residues substantially delayed germination of jungle rice. The time to start germination, time to 50% emergence, mean emergence time, emergence index, and final germination percentage were all... |

| A cultura da canola possui grande importância mundial, ocupando a terceira posição da oleaginosa mais produzida, antecedida pela soja e palma de óleo. O Brasil ainda não consolidou a produção dessa espécie, sendo necessários mais estudos para promover sua tropicalização, principalmente em regiões com temperaturas mais altas. Nesse contexto, o trabalho teve como objetivo avaliar os componentes fenológicos e produtivos de canola sob irrigação visando sua tropicalização. O experimento foi conduzido em área experimental da Embrapa Cerrados, Planaltina, DF, situada a 15°35?30?? S e 47°42?30?? W, a 1.007 m altitude. Utilizou‑se o delineamento experimental de blocos ao acaso, com 16 genótipos de canola e quatro repetições. O híbrido Diamond foi o mais... |

| Soil incorporation of crop residues can lead to weed suppression by posing allelopathic and physical effects. Allelopathic potential of the crops sorghum, sunflower, brassica applied as sole or in combination for horse purslane (Trianthema portulacastrum) suppression was evaluated in a pot investigation. Chopped crop residues alone and in combination were incorporated at 6 g kg-1 soil (12 t ha-1), and a weedy check was maintained. Germination traits time to start germination; time to 50% emergence, mean emergence time, emergence index and final germination percentage were negatively influenced by residue incorporation. Crop residues also exerted a pronounced negative influence on the shoot and root length of horse purslane. Significant suppression in leaf... |

| Abstract: We evaluated the efficacy and residual toxicity of nine commercial insecticides on Plutella xylostella and their selectivity to the predator ant Solenopsis saevissima under laboratory and field conditions. First, to test the insecticides? effectiveness and selectivity, we conducted concentrationresponse bioassays on both species and the mortalities were recorded 48 h after exposure. Next, rapeseed plants were sprayed following label rate recommendations in the field. Finally, insecticidetreated leaves were removed from the field up to 20 days after application and both organisms were exposed to them as in the first experiment. Our concentration-response bioassay indicated that seven insecticides caused mortality ?80% of P. xylostella: bifenthrin,... |

| Abstract: Given its high energetic efficiency, canola (Brassica napus L.) constitutes a potential biodiesel feedstock. However, since this crop is native to temperate regions, Brazil has not yet consolidated its production. Thus, the objective of this study was to evaluate agro-nomic performance of canola hybrids grown in the tropical Brazilian Cerrado (15 ° 35'18 "S, 47° 43'57" W at 999 m), aiming to select promising candidates for crop expansion. Our hypothesis states that obtaining high canola yields in Cerrado conditions is possible given a favorable agronomic adaptation of the species to this environment. Eight commercial canola hybrids were evaluated for seven agronomic traits in three experiments. Data were subjected to joint ANOVA and Tukey test.... |

| Brassica oleracea var. acephala L. (kale) is widely grown in the Black Sea Region of Turkey. Kale growing has not been common in the other regions of Turkey. A number of diseases can seriously afect Brassica crop production. Field surveys were done to determine the occurrence of viruses in kale-growing areas in Ordu in 2013-2014. Leaf samples were collected from kale plants and tested for the presence of Turnip mosaic virus (TuMV), Cauliflower mosaic virus (CaMV), Turnip yellow mosaic virus (TYMV), and Cucumber mosaic virus (CMV) by DAS-ELISA and bioassays. Result of serological and biological tests showed that 7.7% of these samples were infected with TuMV. However, CaMV, CMV, and TYMV were not detected in any of the tested kale plants. The occurrence of... |
