Effectiveness of systemic insecticides applied on the trunk, in the control of Oncometopia facialis
sharpshooters
Introduction:
"This study was developed to evaluate the effectiveness of
systemic insecticides and their doses to control the Oncometopia
facialis sharpshooters, one of the vectors of Citrus Variegated
Chlorosis (CVC), a disease that threatens Brazilian
citriculture, especially the State of São Paulo and the Triângulo
Mineiro region. In 2000, a survey determined the presence of 68
million infected plants, from initial to severe symptoms, which
corresponds to 34.03% of the total of orange trees of those
regions".

Fruit Pathology - Disease Diagnostic Key
"The
diagnostic keys for deciduous tree fruit diseases were developed to aid field
personnel in the identification of diseases that are common to the mid-Atlantic
region of the United States. The keys are arranged to guide the user through a
series of logically arranged statements describing symptoms and signs of fruit
tree diseases. By selecting from a series of numbered statements, those which
most closely describe observations made in the field, the user should be able to
narrow the possibilities to only one or a couple of probable diseases. Clicking
on the symptom description (if highlighted) will link to a photographic image of
the symptom. Some disease names are linked to Fact Sheets containing additional
information on biology and disease monitoring".

Index of fruit disease photographs, biology and monitoring information
"The
following plant pathologists provided written material, photographs, or both,
for The Mid-Atlantic Orchard Monitoring Guide. Photos from the Guide were used
to link to the symptom descriptions in the disease key, and photos and text from
the Guide were used to develop the "fact sheet" pages.
Also, some of the authors listed below provided articles and photographs for the
"Fruit
Disease Focus" series".

Transgenic Virus Resistant
Papaya: new hope for controlling papaya ringspot virus in Hawaii
Papaya
is a tropical fruit crop that is normally consumed fresh and is
valued as a health food because it's rich in vitamins C and A.
In Hawaii, small high quality papayas, called the Hawaiian solo
type, are grown commercially for export to the mainland United
States and Japan. It is the state's second largest fruit crop.
However, papaya is severely damaged when infected by the papaya
ringspot potyvirus (PRSV), which is rapidly transmitted by a
number of aphid species. In fact, PRSV causes the most serious
virus disease of papaya worldwide.
