Felicia grows nematode-free garlic, which she sells as clean seed. She’d like to prevent loss to Fusarium and tested a copper spray and biostimulant spray as potential ways to control the fungus. Key Findings:
  • The dry conditions and good seed garlic led to low Fusarium pressure this year.
  • Felicia found no difference in the proportion of garlic with visual signs of infection by weight of good garlic when she compared plots treated with copper spray, RhizoVital® spray and no spray.
