  1. PLPA 100 JEOPARDY

  2. They are eukaryotic, heterotrophic, and reproduce by spores What are fungi?

  3. A long-term deterioration of forests thought to be caused, in part, by the deposition of acid rain What is forest decline?

  4. The feature that distinguishes a plant parasitic nematode from all other nematodes What is a stylet?

  5. Prokaryotic plant pathogens that reside in phloem cells, are related to bacteria, and lack a cell wall What are phytoplasmas?

  6. The primary nuclear condition of most basidiomycetes, including rust fungi What is dikaryotic?

  7. A German botanist who was the first to show that late blight of potato was caused by a fungus, which he named Phytophthora infestans Who was Anton deBary?

  8. He discovered the antibiotic penicillin on a contaminated petri-plate Who was Alexander Flemming?

  9. He was the first to suggest that black stem rust of wheat was caused by a fungus Charles Persoon

  10. Known as the father of botany, this student of Aristotle recorded many details about stem rust on wheat Who is Theophrastus?

  11. The scientist who showed that the causal agent of tobacco mosaic could pass through filters that would filter out bacterial pathogens. He is now known as the father of virology Who is Martinus Beijerinck?

  12. This plant disease was first discovered in the U.S. in a zoo in New York What is chestnut blight?

  13. Initial efforts to control the spread of Dutch elm disease included the spraying of this, now banned insecticide What is DDT?

  14. Before 1935 this had never been done with viruses What is virus purification?

  15. A disease studied by Thomas J. Burrill at the University of Illinois What is fire blight?

  16. This festival was held in ancient Rome to ask the rust gods to allow a bountiful wheat harvest What is the Rubigalia?

  17. An agent that carries a pathogen from an infected host to a healthy host What is a vector?

  18. The process by which a pathogen penetrates and colonizes host tissue. What is infection?

  19. The form of virus transmission in which the virus remains in the vector for a long period of time What is persistent transmission?

  20. The specific life stage of the nematode which emerges from the egg. What is a second stage juvenile?

  21. These are the five spore stages of a macrocyclic rust What are basidiospores, pycniospores (receptive hyphae), aeciospores, urediospores, and teliospores?

  22. Often the cheapest, and most reliable form of disease control What is host resistance?

  23. A control method of disease control based on preventing the host plant from coming into contact with the pathogen What is avoidance?

  24. The use of an organism to control a disease or pathogen What is biological control?

  25. Fungicides that can kill fungal pathogens after they have infected the plant host What are eradicant fungicides ?

  26. A form control in which the host is infected with a mild strain of a virus to protect it from more virulent strains What is cross protection?

  27. An eastern U.S. forest tree once prized for wood, bark, and edible fruit What is a chestnut?

  28. Plants formed by crossing two genetically distinct parents What are hybrids?

  29. A plant who’s ancestors include emmer and einkorn What is wheat?

  30. The water transporting tissue of a plant What is xylem?

  31. The layer of meristematic tissue in a woody plant that produces phloem to the outside, and xylem to the inside What is vascular cambium?

  32. Ascomycete fungi that are widely used to leaven bread and to produce ethanol What are yeast?

  33. A common component of car exhaust, it also causes white specks on exposed plant leaves What is ozone?

  34. The mycotoxins produced by the fungus Aspergillus flavus What are aflatoxins?

  35. After establishing feeding sites, the adults of these pathogens never move again What are sedentary nematodes

  36. The acronym is ELISA What is enzyme linked imunosorbent assay?
