The fungus Trichoderma viride which is antagonistic to silver leaf was developed as a biocontrol agent for control of silver leaf.
- It was used either as a spray to pruning cuts or as pellets introduced into the trunk of the healthy tree.
- The treatment proved effective in small scale trials, but the results were inconsistent in multisite, larger scale trials particularly on apple trees.
- The fungus was available commercially as ‘Binab T’, but currently is no longer registered in the UK.
