Presentation Transcript

  1. Fungi are microscopic plants which lack chlorophyll and conductive tissue. They cause: - Stem rust - Brown rot - Corn smut - Damping off - Powdery mildew Fungi

  2. Fungi Life Cycle Spore Production:

  3. Bacteria are microscopic single-celled organisms. They cause: - Galls - Scabs - Leaf spots - Systemic disorders - Soft rots Bacteria

  4. Bacteria Life Cycle Division:

  5. Nematodes are very small non-segmented worms. Nematodes cause: - Galls on roots. - Root lesions. - Injured root tips. - Lower yields. - Excessive root branching. - Decreased plant health. Nematodes

  6. Nematode Gut or Intestine Excretory Pore Esophagus Anus Ovary Spear Vulva Ovary

  7. Nematode Damage This type of nematode feeds and moves outside of roots throughout its life.

  8. Pathogenic particles which infect higher plants and animals. Viruses can only multiply in living cells. Viruses cause: Stunting of plants. Yellow mosaic patterns on leaves. Flower break. Vein clearing (chlorosis of leaves).. Viruses

  9. Virus Life Cycle Synthesis: (Avirus needs to be inside a living cell to multiply.)

  10. Other Invertebrate Pests Sucking Insects Chewing Insects Mites

  11. Other Invertebrates Pests (cont’d.) Snail Slug Millipede Centipede
