1. Herança da resistência da soja à podridão radicular de fitóftora, em variedades comerciais brasileiras
The phytophthora root rot (PRR), caused by Phytophthora sojae (Kaufman &Gerdman), is one of the most destructive soybean diseases and can provoke yield losses of up to 100%. PRR has occurred more frequently in Brazil since the season 2005/06, mainly in the South region. There are some resistant commercial varieties but their inheritance remains unknown. All

2. Ferrugem asiática da soja : resistência, controle químico e tolerância
The asian soybean rust (ASR) caused by Phakopsora pachyrhizi Syd. &P. Syd. is the most destructive leaf disease of this culture. The objective of this study was to assess forms of resistance to complement traditional qualitative resistance (vertical), through studies of quantitative resistance (horizontal) and tolerance, conditioned by minor genes, which may

3. Mapeamento de genes de resistência ao vírus da necrose da haste da soja utilizando marcadores moleculares microssatélites
Identificada pela primeira vez no Brasil na safra 2000/2001, a necrose da haste da soja (NHS) é causada pelo vírus CpMMV Cowpea mild mottle virus, pertencente ao grupo Carlavirus. É uma virose altamente destrutiva, que pode levar à morte das plantas. Essa virose tem se disseminado pelas lavouras de soja do país, por meio da mosca branca (Bemisia taba

4. Partial resistance and fungicides on soybean asian rust control / Resistência parcial e fungicidas no controle da ferrugem asiática da soja
Soybean asian rust, caused by the fungus Phakopsora pachyrhizi, is one of the major pest problems in the crop. Disease control has required a combination of cultural practices to minimize losses. Among the control methods, chemical control with fungicides, has been the only one available. Control strategies, such as the use of cultivars with partial resistan
