Result:

  • The effectiveness against C. Cassiicola of antagonistic microorganisms Trichoderma TH1, TH2, TH3 reached from 9,82 – 10,02% of the infected leaf index, after 30 days of observation on young rubber plants.
  • The effectiveness against C. Cassiicola of antagonistic microorganisms Trichoderma TH2, TH3 reached from 24,66 to 25,47% of infected leaf index, after 30 days of observation on mature.
  • Antagonist Trichoderma TH2 showed stronger antagonism against C. Cassiicola than antagonistic Trichoderma TH1 and TH3.
