Abstract

Provided herein are systems and methods for diagnosing plant anomalies found at remote locations using video imaging. A diagnostic technician at a diagnostic station is capable of diagnosing a plant anomaly and recommending a course of action based upon images trasmitted from a remote workstation. The diagnostic technician has access to a database of images and/or descriptions of plant pathogens, lesions and other anomalies to assist in making a diagnosis. It is further preferred that field data relevant to the diseased plant sample is collected at the remote workstation and provided to the diagnostic technician for diagnostic purposes.

Claims

1. A remote imaging system for diagnosing plant anomalies comprising:

(a) a remote workstation, said workstation comprising a means for videomicroscopy;

(b) a diagnostic station, said diagnostic station having means for receiving images transmitted from said remote workstation, viewing means for displaying said images, a database of plant anomalies for comparison with said images, and archiving means for storing said images in a retrievable format; and

(c) a transmission means for sending said images from said remote workstation to said diagnostic station.

2. A remote imaging system according to claim 1, wherein said workstation comprises a stereomicroscope for viewing a sample taken from a plant, a compound microscope for viewing causal organisms present in said sample, and a video camera, mounted to said stereomicroscope and said compound microscope, for acquiring images therefrom, and a digital microprocessor with a framegrabber board for capturing images.

3. A remote imaging system according to claim 2 wherein said remote workstation further comprises means for manipulating said stereomicroscope and said compound microscope from said diagnostic station.

4. A remote imaging system according to claim 1 further comprising a macroscope for capturing non-magnified images of a diseased plant.

5. A remote imaging system according to claim 1 wherein field data are transmitted along with said images.

6. A remote imaging system according to claim 1 wherein said images are displayed and viewed in real time at said diagnostic station.

7. A remote imaging system system according to claim 1, wherein said plant anomaly is selected from the group consisting of genetic abnormality, insect injury, chemical injury, environmental injury, and plant disease.

8. A remote imaging system according to claim 7 wherein said plant disease is a pathogenic disease.

9. A remote imaging system according to claim 8 wherein said plant pathogenic disease is a fungal disease.

10. A remote imaging system according to claim 8 wherein said plant pathogenic disease is a foliar disease.

11. A remote imaging system according to claim 1 wherein said plant is a crop plant.

12. A remote imaging system according to claim 11, wherein said crop plant is corn.

13. A method of diagnosing plant anomalies comprising:

(a) preparing a sample from a plant at a remote location, said sample preparation comprising removing tissue from said plant;

(b) viewing said sample with a stereomicroscope;

(c) capturing images from said stereomicroscope and a compound microscope with a videocamera and microprocessor with a framegrabber board located at a remote workstation;

(d) transmitting said captured images to a diagnostic station;

(e) displaying said images at said diagnostic station; and

(f) diagnosing said plant anomaly from said displayed images.

14. A method according to claim 13 further comprising the step of comparing said image received at said diagnostic station with images stored in a database of plant anomalies.

15. A method according to claim 13 further comprising:

(a) capturing non-magnified images of said plant with a macroscope and microprocessor with a framegrabber board at a remote workstation; and

(b) transmitting said images collected with said macroscope to said diagnostic station.

16. A method according to claim 13 wherein field data are transmitted along with said images.

17. A method according to claim 13 wherein said images are displayed and viewed in real time at said diagnostic station.

18. A method according to claim 13 wherein said plant anomaly is a plant disease.

19. A method according to claim 18 wherein said plant disease is a pathogenic disease.

20. A method according to claim 19 wherein said plant pathogenic disease is a fungal disease.

21. A method according to claim 18 wherein said plant disease is a foliar disease.

22. A method according to claim 13 wherein said plant is a crop plant.

23. A method according to claim 22 wherein said crop plant is corn.

24. A method of diagnosing fungal diseases in plants comprising:

(a) preparing a sample from a diseased plant at a remote location, said sample preparation comprising the steps of;

(i) removing tissue bearing lesions from said diseased plant;

(ii) culturing said tissue under conditions sufficient to promote the sporulation of any fungi present in said lesion;

(b) viewing said cultured tissue with a stereomicroscope;

(c) preparing a microscope slide of fungi from said cultured tissue;

(d) viewing said fungi from said cultured tissue with a compound microscope;

(e) capturing images from said stereomicroscope and said compound microscope with a videocamera and a microprocessor with a framegrabber board located at a remote workstation;

(f) transmitting said captured images to a diagnostic station;

(g) displaying said images at said diagnostic station; and

(h) diagnosing said fungal disease from said displayed images.

25. A method according to claim 24 further comprising the step of comparing said image received at said diagnostic station with images stored in a database of plant pathogens and lesions.
