Abstract

The fall caterpillar (Spodoptera frugiperda J.E. Smith) is a polyphagous species native to the Americas that causes frequent, severe damage to maize. The results of the study showed that the dose of potassium had a significant effect on the tolerance of Spodoptera frugiperda of the sticky maize variety HN92 in Phu Tho province. The density of Spodoptera frugiperda, the damage level and the rate of damage was lowest when applying potassium at a dose of 100 kg K2O/ha and the highest at 20 kg K2O/ha.
