Smokin' Doc Thurston's Greatest Hits

H. David Thurston

Professor Emeritus - Department of Plant Pathology, Cornell University, Ithaca, NY, 14850 (

Probably no more atrocious title for a serious internet page with pictures on tropical agriculture, crops, plant diseases, and sustainable agricultural development was ever conceived, but it is "attention getting" and the title is so bad it might even be considered good. Our department photographer (Kent Loeffler) and his fiendishly clever assistant (Ed Mackillop) were the individuals that came up with the title and cover design.

This page has over 2,500 pictures on it. Kent Loeffler and Ed Mackillop were the individuals that did the hard work of scanning my slides into high resolution files (12-20 MgB) and also putting them all on CD disks as JPEGs. They also help set up this web page. I am indebted to them for their hard work and ingenuity on this project. Ken Sandlan, our department computer guru was also most helpful in this matter.


The contents of this page consist of over 2,500 pictures, most of which I have taken in the last 50 years in various parts of the world. Many are from slides I have used in teaching courses on conventional plant pathology, tropical plant pathology, agricultural development in the tropics, sustainable development, and traditional practices of farmers in developing countries. They might be useful in your work, in your teaching, or for your edification.

There are two Microsoft programs on the page. They are both a compressed Microsoft Word Index document (Mac: Index.sit, PC: which, using the Find Command, you can use to find specific items on the page. Where the information is available, each picture on the disk lists: Slide Number, Date, Site, Hosts, Disease Name, Subject,Scientific name, Slide credit, and Additional information. When locating a specific slide, you must scroll up to the first slide in the category to determine the cateogory title. For example, if you search the document for "mountains," Microsoft Word will highlight #36. You must then scroll up to find that this slide is in the TRADAG5 group.

All of these pictures are also available in high resolution files (12-20 MgB) here in the Plant Pathology department of Cornell University, Ithaca, NY. Write to me ( or Kent Loeffler ( if you want one of the pictures at a high resolution. A $ 15.00 handling charge for sending you each high resolution file would be appreciated. High resolution pictures can be sent via email if the receiving server can accept files of this size (certain servers have a file size cap and will not receive large files) or can be burned onto a CD and sent by US Postal Service. Please indicate a preference when requesting a file.

You will note that in the MS "Index.doc"under "Slide Credits" that whoever took the picture is credited. I took most of them, and it is not necessary to obtain my permission to use a picture, but where they are used elsewhere appropriate credit would be appreciated. However, anyone that uses a picture I did not take will be responsible to obtain permission from the "author" or "owner" of the picture, especially if the picture might be copyrighted. Where it is unclear who is the "author" or "owner" of a picture, this is indicated by questions marks and you use them at your risk. Feel free to use the pictures with these restrictions in mind.

Let me know if you have questions.
