Control Methods and Citrus Health Response Plan


 

Content:

This webpage contains documents and links related to post January 2006 efforts to control or manage the dissemination of citrus canker within Florida, and to prevent the export of canker to areas outside Florida.

A series of programs have been initiated at both Federal and State levels. The emphasis of this program is to prevent introductions of citrus canker from nurseries to groves. Compliance programs are directed at all citrus diseases, however the most immediate threat to Florida's citrus is citrus greening disease, not citrus canker.

The Citrus Health Response Plan (CHRP) was developed following the end of the Citrus Canker Eradication Program in January 2006.

According to the USDA- APHIS website:

"The goal of the Citrus Health Response Program (CHRP) is to sustain the United States' citrus industry, to maintain grower's continued access to export markets, and to safeguard the other citrus growing states against a variety of citrus diseases and pests. This is a collaborative effort involving growers, Federal and State regulatory personnel and researchers.

APHIS, working closely with regulatory officials from Florida and other citrus-producing States, industry stakeholders, university scientists, and scientists with USDA's Agricultural Research Service, has developed the CHRP to compile industry production guidelines and best practices for fruit and nursery stock production that addresses citrus canker and other citrus diseases. The CHRP provides guidelines for nursery stock product compliance and fruit inspection, treatment, and certification. The CHRP will also identify minimum standards, where available, for implementing appropriate survey, diagnostic, and mitigation measures to reduce the proliferation and spread of citrus canker, citrus greening, and other diseases of regulatory significance."

The Asian citrus leafminer was never considered a very harmful pest, except that it increased the risk of citrus canker. However, commercial growers may use a variety of insecticides to control Asian citrus psyllid, which vectors citrus greening.

Citrus Health = Bee Death?

This topic is covered in Chapter 10 of my book. All the documents cited in the chapter are easily located on the internet.

I cite a discussion in Wikipedia as follows:

Imidacloprid

The EPA is responsible for renewal of registration of imidacloprid. I conclude that only a colony level assessment of these insecticides addresses the concerns expressed by scientists.

The CHRP is focused on minimizing the risk of all harmful citrus diseases and pests. Citrus greening is, at present, the most damaging disease.

As research programs are continuing and programs are evolving, the websites of the American Phytopathology Society (www. apsnet.org), the USDA/ ARS, USDA/APHIS, FDACS/DPI and UF/IFAS should be searched for additional information. A few of the more relevant links are listed below.
