| 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 Status: Completed Start date: Sat Nov 01 00:00:00 GMT-03:00 2014 |
| 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 Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| 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 Status: Completed Start date: Mon Sep 01 00:00:00 GMT-03:00 2014 |
| 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 ...

| 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 Status: Completed Start date: Sat Nov 01 00:00:00 GMT-03:00 2008 |
| 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.

The ‘cipó-titica’ vine (Heterops flexuosa) is a non-timber forest product of economical importance in Amapá. Its long and resistant aerial roots have historically been used for crafting furniture, utensils and handcrafts. The project will be situated in Nova Canaã settling, at Porto Grande municipality (Amapá) and aims to evaluate cipó-titica plants density in the forest in order to identify phorophytes (tree species that host the vine) and thus determine the rate of growth and emission of ne ...Status: Completed Start date: Sat Mar 01 00:00:00 GMT-03:00 2014 |
| The collared peccary ( Tayassu tajacu) are rustic and gregarious animals who provide meat and leather of excellent quality, being thus an important source of protein especially to the subsistence of the Amazon's needy population. The use of this animal is, however, being done without planned hunting, being thus associated with the destruction of their natural habitat and, consequently, the loss of these resources, which are scarcely known.

| A crescente demanda de água para fins industriais e residenciais, geração de energia, mineração, lazer, somados aos problemas ambientais, faz com que quantidade de água para a agricultura apresente uma tendência de redução. A agricultura é o maior usuário de água em todo o mundo. O setor agrícola brasileiro é o principal usuário consuntivo dos recursos hídricos. Uma provável solução para esse problema é aperfeiçoar como a água é manejada, o que envolve a adoção de tecnologias e procedimentos ade ...

| 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.
