The main environmental problems associated with the waste produced in intensive pig farming are its high organic load, high amount of nutrients, the presence of some metallic species and of micro-organisms, some of which are known pathogenic agents. In general, the waste treatment systems in pig farms still lack the ability to reduce or eliminate pathogenic agents from the waste produced, a fact which makes it difficult to reuse the water in the very facility or even in agriculture. Seasonal flu

The process of organic waste biodigestion is quite old, as the first unit was installed in Bombay, India, in 1819; in Australia, a company has produced and industrialized methane from sewage since 1911. China has 4.5 million biodigesters that produce gas and organic fertilizer, the main role of which is sanitation in rural areas. However, different aspects related to biodigesters are still lacking. This work aimed at studying and improving a biodigester system, and its general goal was the devel

This project aims to increase the adoption of fruit fly management practices for agricultural communities in Uganda, a country on the African continent. The proposal came about due to the observance of damage and economic losses in orchards in Uganda, caused by fruit flies, especially Bactrocera dorsalis, which stems from the low use of efficient management techniques. Although the infestation is lower in farmers' orchards that use management techniques such as toxic baits, methyl euge

Bovine tick parasitism is a determinant of estimated losses of US $ 3.4 billion annually in Brazil. Much of these losses are due to mistakes made in the controlling attempts. The three main mistakes made are the use of an inappropriate acaricide at the wrong time and in the wrong way. In view of this situation, Embrapa Dairy Cattle implemented the acaricide effectiveness testing, a free service based on the determination of the most suitable product for application in each property, based on sam

The infection of the swine herd with Salmonella and consequently, the presence of this micro-organism in swine products, has been a serious concern since it can be a great threat to the consumers themselves. Embrapa Swine and Poultry and UFRGS teamed up to develop tools and epidemiological studies that can characterize the problem, the contamination sources and the infection dynamics in the country's southern herds. This project aims to propose a systematic control of the Salmonella infection in

Brazil is a tropical country with an extensive territorial area and vast plant diversity. This makes the weed species that infest the crops be widely varied. Such characteristics differentiate Brazil from other countries with temperate climates. GM crops that are resistant to herbicides, especially to glyphosate, have created a new scenario for weed control in Brazilian agriculture. Farmers have adopted RR technology right away as efficiency and cost are its main benefits. The use of glyphosate

Wheat ( Triticum aestivum L.) is the world's second largest crop and Brazil has taken second place in wheat production in South America. However, productivity in this crop can be limited due to occurrence of some diseases, one of which, wheat blast, caused by the Magnaporthe grisea fungus, has caused large productivity losses that can reach 72% depending on the time of infection. With the expansion of wheat crops to other Brazilian regions such as the Midwest, the fungus has been settling in and

Losses caused by the parasitism by ticks in cattle are estimated at 3.24 billion dollars annually in Brazil, largely due to procedural errors, such as the systematic and often inappropriate use of acaricides, resulting in selection and proliferation of populations of acaricide-resistant ticks. In addition, there is a growing demand for new alternatives in pest control, aiming at minimum use of chemicals, in order to preserve the environment and ensure residue-free food. In this context, biologic

GM crops that are resistant to glyphosate have created a new scenario in Brazilian agriculture. Glyphosate has been generally used mainly in soybean farms in the Brazilian states of Rio Grande do Sul, Santa Catarina and Paraná. In the state of São Paulo, glyphosate is widely used in orchards, especially citrus ones. The repeated use of glyphosate has given rise to cases of weed resistance to this herbicide in different places of the country. The trend is that new glyphosate resistant crops such ...

Whitefly is currently one of the main pests in Brazil. The insect causes direct damages (sap suction, toxin injection, and physiological disorders) and indirect damages (helping sooty mold grow and transmitting phytopathogenic viruses). Reports of damages started right after its entrance in the country, the likely source of which has been traced to an import of ornamental plants in the 1990s. After this introduction, the insect became very well adapted to Brazilian cropping conditions and spread
