phenolic contents of the plants. Accumulation of phenols in AM plants
along with peroxidase, peroxidase (PRO) and polyphenol oxidase (PPO)
and, higher accumulation of phenols impart disease resistance. Some of
the successful application of AMF in disease management is shown in
Table 14.4.

14.3.7 CONTROLLING PHYTOPHAGOUS INSECTS
Interaction with herbivorous insects is also altered in mycorrhizal plants,
as the symbiosis has an impact on the growth and/or survival of those in-
sects. In general, AM reduce the incidence of generalist chewing insects,
while sap feeding or specialist insects show increases in performance
on mycorrhizal plants. As a result, insects are affected by the enhanced
defense capacity of mycorrhizal plants, for example, reduced the perfor-
mance of potato aphids in tomato due to
G. mosseae
.
