Loss of Friend to ISCN

2011-05-02T21:01:00.001-07:00

It is with great sadness that I share that our dear friend, Peter Jurisich of New Zealand passed away last week. I will always remember Peter as he is pictured below. A floppy hat, brilliant grin with a mischevious glint in his eye. He was a passionate man and we were fortunate that one of his passions was the citrus nursery business! Peter, you will be missed....

FAO Announcement from ISCN President Paco

2011-04-14T17:26:00.000-07:00

I am pleased to inform you that the FAO coordinator (Francesco Gibbi) has been visiting the Argentinean Ministry of Agriculture during this week and accepted my proposal to hold the RIAC/IANET workshop in Tucuman (Argentina) as the site for the RIAC/IANET workshop. Thus, those who have already taken their international travel flights, should not worry about changing dates, and will have the opportunity to participate in the RIAC/IANET workshop .

The plan is as follows: RIAC members will join our field visits the 15th of June, as ISCN Congress presentations on the 16th, and will continue on the 17th all day and maybe the morning of the 18th for final conclusions .

The FAO confernce may be using the Catalinas Park Hotel and the same halls oas the ISCN Congress, if an agreement on costs is reached. RIAC/IANET is negotiating with the hotel and local organization.

However, all participating in the POST-Congress in Chile, they need a full traveling day: from Tucuman to Buenos Aires, change to the International airport and take another flight to Santiago de Chile. There are no direct flights from Tucuman to Santiago de Chile, and the road route that was considered initially has been ruled by the distance (about 1500 km) and the risk of roads closed by snow and ice.

Please consult the Congress website frequently, which has been updated with Pre and Post Congress information.

Up to now 90 participants have been registered, so I hope to get around 250 to 300 in Tucuman. From AVASA we'll be 8 to 10 (Pre+C+post).

Paco

The American Continent accounts for nearly 45 percent of world citrus production and 84 percent of world trade of fresh and processed citrus. The variety composition of the citrus industry of Argentina and other South American countries has shifted in recent years because of changing demands in both overseas and domestic markets. Most popular varieties depending on the country are Lisboa and Eureka lemons, late ripening oranges such as Valencia, Pera, Midknight and Delta; Salustiana and other midseason; Navelina, Lane late and other navel oranges; Satsuma, Nova, Murcott, and Clementine mandarins and a few grapefruits. Nowadays, citrus growers are demanding new patented varieties. The majority of South American countries have a certified citrus nursery tree program to guarantee the use of high quality propagation material to provide there citrus industry, but the level of implementation and success is variable. Huanglongbing has arrived to the continent is rapidly spreading and threats the citrus industry of several American countries changing the way to grow nursery trees, safely.

Key words: propagation material, varieties, certified citrus nursery tree program.

Membership Communication

2010-07-14T09:30:00.000-07:00

Utilizing the power of MS Outlook an ISCN member dtatbase has been developed that will allow the executive board to communicate with members. In addition, ISCN would like to add new contacts to this list that may be interested in the functions of the organization. MS Outlook allows us to sort the listing and separate members vs. non-members and will also allow some biographical information to be compiled as it becomes available. If you are reading this blog and would ike to be added to the e-mail distributions, please send an e-mail to rsmith@citrustreesource.com and we will add you to our list. Include Name, Address, Phone numbers, Company name, web site, and any other information you would like to offer ISCN.
It has been a long time coming, but the new ISCN web site is again under construction. We don't have a completion date to offer up, yet, but Andrew Lee is committed to insure it gets done very soon.
Over the next few weeks, an effort will ensue to attain "Country Representatives" for ISCN. These are nurserymen from nations with citrus nurseries that speak English and are willing to disseminate ISCN information to citrus nurserymen in their countries and translated into their nation's language. In this era of e-mail and the internet, it should be easier for ISCN to serve a larger population of citrus nursery people, even if they can't attend a Congress. Establishing "Country Representatives" is an important step in this process. If you would like to volunteer to be a representative, please contact ISCN Secretary, Roger Smith at the above e-mail address.

Dear friend,

These are times of great changes for perhaps all of us but especially for the citrus industries of the world. Huanglongbing (greening disease) now threatens the two largest citrus industries in the world and as its vector Diaphorina citri moves into new areas along with Toxoptera citricida the prime vector of tristeza - new and serious problems will arise.I wish to share with you a new slide show on the history of indexing for citrus. This is more or less a review of my lifes work in this field. I was asked to present this work as an invited lecture at the 8th International Congress of Citrus Nurserymen in October, 2008 in Chongqing, China. I have now converted my Power Point lecture to an EcoPort slide show number 209 and I share this with you. You can access this slide show with the URL below or go into http://www.ecoport.org/ww.ecoport.org/ - Click on pictures, then on slide shows and enter 209. Click on 209 on the far left to bring up this slide show and you can also download this show as a permanent file.What I would appreciate is for you to suggest any errors or updates, or you can send me a picture or two with text for inclusion into this, or any of the various slide shows. These can readily be included into the slide shows as well as any editing you might suggest.Here is the URL for this slide show titled Indexing for Graft-Transmissible Diseases of Citrus: Its History, Importance, Current status and use in Certification Programs. http://ecoport.org/ep?SearchType=slideshowList&ID=209I also enclose this URL as a direct link to all of my EcoPort slide shows and eArticles: http://ecoport.org/ep?SearchType=domainContents&id=9&type=group SearchType=domainContents&id=9&type=group

The picture shows the planting of the first citrus tree in the Foundation Block at Lindcove, California in 1961 (yes, it is Chet). This tree was the result of five years of indexing, growth and preparations.

Abstract: Prior to 1945 indexing for the detection of citrus graft transmissible pathogens (CGTPs) was limited or non-existing since virus and virus-like diseases of citrus were poorly understood or little known. The common practice was for growers and nurserymen to select their budwood for propagation from their best and most productive trees. However, in later years it was discovered that even their best trees were often symptomless carriers of one or more dangerous CGTPs. Topworking was, and still is, a common practice which perpetuates the spread of infectious diseases. Following up on the seminal finding by Fawcett (1933) on the virus nature of psorosis, the first registration program for citrus was initiated in California providing growers and nurserymen with psorosis-tested budwood. Between 1937 and 1961, field inspections of mother trees resulted in over 2,400 trees registered as psorosis inspected. The discovery of a seedling index for psorosis by Wallace (1945) was a major breakthrough in citrus virus detection and a new era of discovery of short term biological indexing for citrus pathogens began. Indexing was reduced from years to weeks for the expression of definitive symptoms of diseases. The worldwide tristeza epidemics in the 1930's initiated a conversion to new CTV-tolerant rootstocks to replace the popular and predominant sour orange. However, with indexing, hidden and symptomless viruses and viroids emerged which led to the recognition that most old clone citrus budwood sources were infected with CGTPs. The virus nature of tristeza was proven by Fawcett and Wallace (1947) and a second major breakthrough in indexing occurred with the discovery that seedlings of the small fruited lime could be used as a rapid indicator for tristeza. The destructive nature of this devastating disease was a major factor for bringing scientists together in 1957 for the first conference and the formation of International Organization of Citrus Virologists (IOCV). Scientists throughout the world could now formally meet and communicate and publish their research on indexing. Certification for citrus took on new meaning and possibilities. In the early 1950's, there were very few greenhouse or laboratory methods available for detection of most CGTPs. However, in relatively rapid succession, new technology for indexing and identifying these graft-transmissible pathogens evolved: the Orlando tangelo for cachexia (1952); the lemon and sour orange for seedling yellows (1952); Mexican lime for vein enation (1953); the trifoliate and Rangpur lime field index (1954) and the laboratory color test for exocortis (1957). In the beginning there were four or five major diseases of citrus for which indexing was proposed and needed for a certification program. These were tristeza, psorosis, exocortis, cachexia and stubborn. Indexing was the key for the identification of these diseases. As indexing methods continued to improved, nearly all existing old line source trees were found to be infected with one or more CGTPs. The nucellars which were found to be free of most CGTPs gained dominance. However, there were many problems associated with the nucellar. The subsequent development of thermotherapy (1957-1972) and shoot tip grafting (1975) virtually ended the interest and the need for the nucellar. With new indexing technologies, certification programs were initiated in Texas (1948), Florida (1953) California (1954) and in Arizona (1955). These programs are briefly reviewed. Detailed histories are presented for indexing for psorosis, tristeza, exocortis, cachexia, and stubborn diseases. Diagnosis by field symptoms plus biological and laboratory tests are presented. A brief look at other CGTPs and their indexing procedures are also presented for the oak leaf pattern diseases of blight, concave gum, cristacortis and impietratura and for citrus chlorotic dwarf, citrus variegated chlorosis, gummy bark, infectious variegation, leprosis, satsuma dwarf, tatter leaf, vein enation and witches broom disease of limes. Technology in virus purification, molecular biology and immunology opened a new era for assays such as ELISA, sPAGE and PCR which utilized the sequence specificities of ribosomal spacer regions. These assays are rapid but though they are both costly and labor intensive they are now important components for indexing in certification programs. The current worldwide destruction by huanglongbing (greening disease) has placed new emphasis on the importance of detection of this disease before it becomes epidemic. Older and newer indexing procedures for HLB are reviewed and an important new technology using RT-PCR for showing the presence of the bacteria inside the insect vector is reviewed. This new technology can show the presence of HLB/greening disease one to two years before field symptoms are seen and verified by PCR.

China Congress Well Attended

2008-11-21T20:36:00.000-08:00

The Congress venue of the Empark Grand Hotel was well appointed and fit the size of the group very well. Our hosts outdid themselves by erecting a large billboard banner behind the stage.

One of the destinations of the field visits was the Chinese Research Institute, near Chongqing. Theis group photo highlighted the great group of student volunteers in the front that were so much help for the foreign attendees.

The Demonstration Nursery we visited is also a commercial operation that is part of the modernization effort going on in nurseries all over China. CRI has spawned 44 modern nurseries in the last five year that have spread through all citrus growing areas in southern China.

China Congress a Success!

2008-11-10T14:19:00.000-08:00

The 8th Congress of the International Society of Citrus Nurserymen was a great success! Our Chinese hosts provided a fine venue and did a wonderful job organizing the Congress. 151 attendees were recorded and 53 attendees paid the $100 membership fee to become ISCN Members for the next period of membership until the next Congress in Argentina in June 2011.
Hassan Marei of Egypt passed the President's mantle off to Francisco Llatser of Spain and Gary Eyles of Australia was unanimously elected to the post of President-elect. Roger Smith agreed to stay on as Secretary and agreed to take on the responsibilities of Treasure as well. The Exectuive Board's goals for the "between Congress period" is to:

1. Invest in a new web site that has e-commerce capability that will allow membership fees to be paid on the web site. The goal is to have the site in English initially, but to develop a means to provide the site Spanish, Portugese and possibly Chinese if the technical challenges can be overcome.

2. Solidify the Area Representatives in all participating countries.

3. Improve organization communication between congresses.

4. Continue to improve the new Congress Manual ffrom lessons learned from the China Congress. The desire to add interactive worksops to the format will be pursued.

ISCN has survived another Congress cycle and it is the executive board's goal to offer the opportunity for it to thrive as we set our sites on Argentina in 2011.
