Changes in Leaf Phenolics and Chlorophyll Content of Maize Inoculated with Glomus intraradices Upon Spodoptera frugiperda Infestation

Maize, the third important cereal crop, is severely affected by Spodoptera frugiperda (fall armyworm). Arbuscular mycorrhizal fungi (AMF) colonized crops are shown to tolerate insect infestation because of systemic priming defence against attack. The present study aimed examine effect various doses AMF (Glomus intraradices) inoculation on triggering tolerance S. in maize. total phenolics and chlorophyll content uninfested leaves obtained from applied attacked treatments were higher over uninoculated plants upon However, a greater concentration was observed treated with maximum spore inoculum 5 per seed. Similarly, plant biomass also same treatment even after infestation. These observations indicate importance sustaining maize growth health during
