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.
