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 ...

Rice and wheat are the two main sources of calories in the human diet, and both are important crops that are exported to the USA. Rice blast, which is caused by the Magnaporthe oryzae fungus, is a limiting factor for the global production of rice and constitutes a very serious emerging threat to wheat in the USA. Research on the disease in last the 20 years has provided a wealth of understanding on the molecular foundation for rice resistance to blast and on M. oryzae's pathogen

Brazil annually consumes 10.5 million tons of wheat, half of which is produced in the country, which entails an approximate outlay of 800 million dollars in wheat imports. The high cost of production and the difficulties in the obtention of cultivars with technological qualities that meet market requirements are among the main limiting factors for the Brazilian wheat production chain. Out of all the cultivars available from all Brazilian breeders, about two thirds were created from germplasm

The soilborne mosaic in wheat is a viral disease whose negative effects on wheat production have become more frequent in several wheat regions in southern Brazil. This disease can reduce productivity by 50% if susceptible cultivars are sown in areas with inoculum and favorable environment conditions. In Brazil, the common mosaic is attributed to Soil-borne wheat mosaic virus (SBWMV) and also to Wheat spindle streak virus (WSSMV), both transmitted by Polymyxa graminis, pla
