Brazil is a major producer and exporter of beef in the world, 90% production made pasture 85% cultivated pastures country are Brachiaria sp. With growing livestock industry recent years, several forage plant diseases became significant importance for causing losses productivity quality. This study aims at quantifying species fungi associated with seeds their frequency plants from tropical regions Brazil. Assays were performed considering: incidence, pathogenicity seed-seedling transmission...
O consumo de mel oferece uma combinação única compostos bioativos e o controle da qualidade deste produto é fundamental importância para garantir a segurança dos alimentos, preservar suas propriedades proteger os consumidores contra fraudes contaminações. Portanto, presente estudo teve como objetivo avaliar 31 amostras obtidas por apicultores das regiões sul norte do Estado Tocantins. Para detectar possíveis alterações, realizou-se seguintes testes: reação Lugol Lund pesquisa corantes....
ABSTRACT The authors aimed to evaluate the resistance gummy stem blight and agronomic traits of melon crop in Southern Region State Tocantins, Brazil, two growing seasons, submitted or not treatment with fungicides. Two experiments were carried out: dry season (experiment I), rainy II), respectively, comprising periods from July October 2013 March May 2014. Six cultivars used each season. In season: Eldorado 300, Hibrix, Dourado Amarelo, Louro, Gaúcho Redondo Canarian; HF-4439, Canarian....
A antracnose foliar é causada pelo fungo Colletotrichum sublineolum Hann. Kabát et Bub. (sin. C. graminicola (Ces.) G.W. Wils.) em plantas de sorgo podendo reduzir a produtividade grãos e forragem, o manejo adequado da nutrição mineral desta planta pode se apresentar como um mecanismo controle sobre antracnose. Dentre os minerais utilizados para doenças, silício destaca-se por severidade das doenças várias culturas. Diante do exposto, este trabalho teve objetivo avaliar diferentes genótipos...
The objective of this study was to evaluate the impact oil extract neem, Azadirachta indica, on watermelon aphid Aphis gossypii and its natural enemy Cycloneda sanguinea. Toxicity bioassays were conducted with commercial product DalNeem (1,475 g L-1 azadirachtin) at 0.0037 µg a.i. mL-1, 0.0074 mL-1 0.0148 Malathion 1 distilled water as a control treatment. products sprayed leaf discs, insects exposed residues. instantaneous population growth rate A. survival C. sanguinea larvae different...
RESUMO Uma das mais importantes doenças que atacam o melão (Cucumis melo L.), é Crestamento Gomoso do Caule, causada pelo fungo Didymella bryoniae altamente agressivo em condições de temperatura e umidade elevadas. Desta forma, presente trabalho teve como objetivo avaliar a eficácia fungicidas associados inseticidas no controle crestamento gomoso caule meloeiro campo naturalmente infestado. O foi realizado dois ensaios, sendo ensaio I, utilizada cultivar Eldorado 300, com os tratamentos...
Studies of several agricultural crops have been concluded with the aim achieving greater environmental balance by reducing use pesticides, as well promoting viability cultural management techniques that diminish proliferation phytopathogens. In melon growing industry, studies this sort are scarce. Therefore, objective work was to evaluate influence on disease progression and crop productivity various production systems, including fertilization, spacing, pesticide use, pruning branches...
The use of plant essential oils has been adopted as less hazardous to the environment and human health than synthetic insecticides used for control insects that transmit diseases. Despite exerting insecticidal activities against several insect disease vectors, potential impacts on non-target organisms exerted by extracted from Lippia sidoides (Cham.) have not received adequate attention. Here, we evaluated susceptibility changes in consumption rates honey bees, Apis mellifera (L.), when...
The soybean cultivation (Glycine max (L.) Merrill) is responsible for the highest pesticides use in agriculture Brazil. There an environmental and social need to reduce of these substances crops. alternative products applied such as plant extracts essential oils, becomes necessary indispensable, mainly disease control. Among plants studied, Noni (Morinda citrifolia L.), has stood out some studies, where relevant fungitoxic results have been demonstrated, however, there are still few works...
Beekeeping has been growing and developing over the years. There are many products that can be explored with this activity, in addition to bringing great benefits their producers consumers. Apis mellifera L. bees carry out an extremely important activity for productivity of agricultural crops, which is cross-pollination vegetables. When visit crops search resources colony and, consequently, promoting pollination, they come into contact pesticides applied control pests, diseases weeds....
O presente trabalho teve por objetivo avaliar o grau de resistencia ao Crestamento gomoso do caule e as caracteristicas agronomicas cultivares melao na regiao sul estado Tocantins cultivados em duas estacoes climaticas submetidos ou nao tratamento com defensivos. Foram conduzidos dois ensaios: estacao seca (ensaio I), chuvosa II), compreendendo os periodos julho a outubro 2013 marco maio 2014, respectivamente. utilizados seis melao, sendo periodo seca: Eldorado 300 ® , Hibrix Dourado Amarelo...
