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

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

The pest aphids Sipha flava and Rhopalosiphum padi have caused significant injuries in elephantgrass and brachiaria swards, respectively. Thus, the objective of this project was to evaluate the bioecology of these pest insects and the predator Chrysoperla externa. The biological aspects of the pests were studied at 12, 16, 20, 24, 28 and 32ºC. Temperatures of 20ºC and 24ºC were more favorable for insect development, and this temperature range is the most appropriate for t ...

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

The adoption of Good Laboratory Practices (GLP) contributes to the development of scientific research, as they result in greater reliability and efficiency of the results. In order to follow some of the current standards, such as GLP or ISO 17025, the laboratory must adopt measures of organization, control, training, standardization and registration of its activities. The laboratory must also adopt practices that guarantee the safety of its personnel and the community in general. Among these is

Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met

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
