What tests to order
Foliage Assay
Allows determination of the area of leaf surface occupied by microorganisms
such as bacteria and fungi.
- The work so far performed suggests that if 70% or more of the leaf
surface is occupied by beneficial microorganisms, then foliar disease can
be significantly reduced. Plants with 70% or more of the leaf surface occupied
by beneficial microorganisms also appear to have higher leaf tissue concentrations
of important nutrients.
- More work is needed to determine which species of bacteria or fungi
will be most suppressive and whether different cultivars of plants will respond
in different ways.
