Research Experience
2005:
internship in the Department of
Soil Fertility and Plant Nutrition at Federal
University of Viçosa (UFV).
2005 – 2006:
internship in the Department of Crop Science –
Fruit Crops at Federal University of Viçosa (UFV).
2007 – 2008:
internship in the Department of Phytopathology
at Federal University of Viçosa (UFV).
2008 – 2009: internship in
the Laboratory of Biological Control of
Fitonematodes in the Department of
Phytopathology at Federal University of Viçosa (UFV).
2008 – 2009:
Development of bionematicide for biological
control of root-knot nematodes in fruticulture
at the region of Janaúba, Minas Gerais, Brazil.
Description: The objective of this project is to
develop a biological control product and process of
production and application of this product, to
control nematodes affecting fruticulture and other
crops (such as sugar cane, coffee, vegetables, and
others). The product was developed and results were
tested from biotechnological researches. It is
based on a vegetal substrate that contains spores of
the bacteria Pasteuriapenetrans, the fungus
Pochoniachlamydosporia, and of some
rhizobacterias. Phytonematodes are responsible for
losses of 10 to 20% of yield production in crops in
Brazil. Cost of nematode control is based on
chemical products that are classified as extremely
toxic by the Ministry of Agriculture. The result of
this project introduced a new technology and a new
method of application that allowed the biological
control of the nematodes. The product was not toxic
to human beings or to the environment. Additionally,
the new product will cost less than the actual
chemical control, which is vital to farmers.

Area of research:
In my research I
will study the influence of soil texture and profile
within alluvial cotton fields in Louisiana on
population development and damage potential of the
Rotylenchulus reniformis.
The objectives of this research are:
-
To evaluate the influence of soil
texture on reproduction and pathogenicity of
Rotylenchulus reniformis on cotton.
-
To develop management zones for
cotton fields in Louisiana infested with the
R. reniformis.
