So just exactly how does some CT brews suppress plant pathogens? It
has been suggested many times in this forum that it is simply numbers.
The fungi and bacteria when sprayed on the leaves overwhelm and out
compete most plant pathogens. Or could it be a more specific mode of
action that is responsible? Or has something activated the multiple
defense signal transduction pathways? 1 bacterial resistance pathway,
2 salicylic acid dependent pathway and 3 jasmonate/ethylene dependent
pathway? Causing an incompatible interaction, hypersensitive responce?
Have any real control studies been done? Has RNA been isolated and
analyzed to determine expression levels of these pathways or level of
gene expression? That is the sort of data I would be glad to embrace.
Direct undeniable plant specific response to product being used. Take
care hi_yield.
