The damage caused by spittlebugs varies according to the species of grass, and the losses can reach alarming levels. Measures for population control are currently restricted to the use of resistant grasses and pasture diversification. Therefore, alternative control measures are necessary, such as the use of botanical insecticides (organic compounds extracted from plants). The objective of this study was to evaluate the insecticidal activities of thymol, carvacrol, eugenol, cinnamaldehyde, and tr

Computation used as a tool by scientific research has revolutionized the biological sciences, as it has done with many other fields of science, and considering the exponentially increasing amount and complexity of the scientific data being generated and needing to be efficiently handled, translated, processed and communicated, new computational resources are needed for the effective treatment of all this volume of data that makes it possible to transform it into knowledge and subsequently, as th

This project aims to recover legal reserve areas (ARL) or areas of permanent preservation (APP), in regions of family agriculture at the Brazilian Oriental Amazon, in the hopes of reducing impacts resulted from agricultural and forest practices. The project aims to train at least 150 family farmers in management of natural resources in areas which are close to bodies of water, and also to recover and monitor these areas' environment. The project will be developed in micro-basins of the Bragança, ...

Cereal such as wheat, rice, corn, maize, oats, sorghum, millets, triticale, and rye make up the base of human and animal foods and feeds, respectively. Many of these species contribute significantly to the sustainability of agricultural production systems in Brazil, generating jobs and boosting the country's economy. Collectively, these cultures add up to 19 millions of cultivated hectares and 47 million tons of produced grains, which is almost half of the country's total grain production. Howev

The organic production of vegetables is an activity of major social and economic importance in Brazil's Distrito Federal, and it has grown about 30% larger every year, causing a higher demand for knowledge on the establishment of new crops. Tomato is one of the main cultivated vegetables in terms of economic importance, which is central to the management of organic vegetable plots due to countless related plant health problems. From an agroecological standpoint, environmental diversification is

Brazil has several breeds of domestic animals that have been developed from breeds brought by Portuguese colonists at the time of discovery. Over the centuries, these breeds have been subjected to natural selection in environments in which they live to the point of presenting specific characteristics to adapt to these conditions. They are known as “creole", "local" or "naturalized".

Currently, many of these breeds are endangered of extinction because over the centuries, they have

Ecological alternatives may contribute to the attainment of sustainability of productive family units through the balanced use of natural resources in the Amazon. Among these viable alternatives, stand out in the Amazon the initiatives of land preparation without the use of fire, such as the Tipitamba Project, the Roça without Fires Project, Agroforest Systems and agroecological alternatives practiced by the region's farmers. The availability of knowledge and practices through the training of en ...

Embrapa invests in the conservation of native strains of microorganisms, which can be used by the scientific community in several research programs, ranging from diagnosis, treatment of diseases and production of vaccines for human and animal application to reducing the environmental impact of Productive processes and the generation of renewable energy. In this perspective, microbial cultures are being continuously studied for the formation of a database of "active" components and their respecti ...

Sustainability of traditional cultivation systems (slash-and-burn) depends especially on long periods of set-aside in order to reestablish the stock of the soil's nutrients and raw organic material used and/or lost during the agricultural period. Population growth and decrease in the region's secondary vegetation availability has progressively reduced the set-aside period, subsequently increasing the pressure on riparian areas and cultivated ones. The result if degradation of natural resources a

One of the largest livestock problems in Southern Brazil has been the scantiness of varieties of forage species more adapted to this region. In addition, due to global warming and the demand for increased productivity with reduced use of inputs, there is a need of studies on germplasm tolerance to abiotic stresses such as drought, and the evaluation of symbiotic organisms to promote biological nitrogen fixation in grasses. Thus, this project aimed to develop improved populations of some of the m
