Pea (Pisum sativum) - Pea Enation Mosaic

Notes Common pea mosaic virus (CPMV) was found to cause leaves on young plants to show vein clearing and banding. Later a mosaic with dark green and pale-yellow patches occurs. Leaves are narrower, bent and almost closed. Flowers are spotted and smaller in size and may lack bright colors and fall off soon.

Use pesticides safely!

  • Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use.
  • Read the pesticide label—even if you’ve used the pesticide before. Follow closely the instructions on the label (and any other directions you have).
  • Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.
