| Pasture degradation is one of the main problems of Brazilian cattle farming. Several strategies to recover the productivity of degraded pastures have been developed by Embrapa and other research and education institutions. In such studies, reducing the costs of the recovery of degraded pastures has been one of their main focuses. Integrated crop-livestock systems (ICLS) have proved to be some of the best alternatives to reduce the costs of pasture fertilization. ICLS have potential to increase t Status: Completed Start date: Thu Nov 01 00:00:00 GMT-03:00 2007 |
| Productivity and forage quality of elephantgrass (Pennisetum purpureum) are directly affected by weed interference. The difficulty of control of these species is one of the main barriers to production and use of the forage as feedstock, as well as to the production of biomass for energy use. Despite the great progress in agro-ecological weed control techniques, herbicides are still indispensable. Thus, the rational use practices of these products should be improved in order to produce quality fo Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| 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 ...

| Concern about the environmental impacts of agricultural activities has taken on a large dimension, especially in the last decade. These impacts are expressed, for example, in reduction of biological diversity, erosion and contamination of soils, silting and contamination of water springs, increase of agrochemical residues in food, among others. However, the incorporation of the concept of sustainability has led agricultural research in the growing search for alternative and sustainable models of Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| Pastures of Cynodon spp. and elephantgrass ( Pennisetum purpureum Schum.) have their productivity and forage quality directly affected by weed interference. The difficulty of controlling weeds is one of the main obstacles to growing and using these forage crops as an input in animal feeding, as well as in the production of elephantgrass biomass for energy use. Despite the progress in agroecological weed control techniques, herbicides are still indispensable, especially in crops on ... Status: Completed Start date: Sat Jul 01 00:00:00 GMT-03:00 2017 |

| 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 Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2015 |
| The tomato is one of the most cultivated vegetables in the world, and is the target of countless plant health problems. Embrapa Vegetables has historically produced research in plant health within this production chain under the scope of the Tomato Genetic Improvement Project. However, the increasing demand for studies aimed at perfecting pest diagnosis methods and generating essential information for management has signaled the need to create a specific plant health project. Thus, this project Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2012 |
| 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 |
| Evaluate the influence of the following production systems: soybean/off-season cotton, soybean/off-season maize, and cotton-off-season maize over the intra and inter-population genetic variability, need to control, and insecticide resistance levels of brown stink bug Euschistus heros.
