Weird…your summary page says I am the number one person you reply to on this forum.

Anyway, back to budrot prevention…as far as the Trichoderma harzianum goes, check this out:

Doesn’t suggest it’s a cure but can reduce botrytis damage 50%. Seems like this could be a big deal…since systemic fungicides aren’t appropriate for late flower. I do wonder about the water on the buds making things worse though. This experiment was beans not dense buds.

Thanks @vernal and @PlantShepherd for the interesting reading. so from what I can glean, botrytis is frequently a systemic infection that is cryptic as well as a spore spread infection that ‘activates’ when certain criteria are present either environmentally or via plant development stages. Regardless, it seems that high sugar levels on the flowers and excessive nitrogen contributes to botrytis virulence.

Harzianim produces a protein; Epl-1 that has multiple targets…. It up-regulates the plants salysilic/jasmonate defence pathways and down-regulates the virulence genes of botrytis. Harziqmum also a direct myco parasite of botrytis. It appears from most of the reading that seed treatment, foliage application and early flowering are all beneficial times to inoculate with Harzianum. I’m going to do some tests with some control plants… not laboratory protocols so results may vary as they say…I might also check Brix levels to see if there is any relationship.
