Abstract
Soil pH-induced stress conditions affected the amount of foliar damage to whorl-stage sorghum caused by larvae of Spodoptera frugiperda (J.E. Smith) in Georgia, USA. Visual ratings of foliar damage demonstrated that sorghum plants grown on more acidic soils (pH below 5.4) incurred greater foliar losses than plants grown on soils with more optimal pH levels (pH above 6.0). Adverse soil pH retarded plant development and growth rate, which caused plants grown on the more acidic soils to remain in the seedling and whorl stages longer than plants grown on the less acidic soils, thereby extending the period in which S. frugiperda could attack the foliage
