ABSTRACT
The main pest that attacks sweet corn crops is the armyworm Spodoptera frugiperda J.E. Smith. The armyworm S. frugiperda has been found to be harmful to sweet corn crops with an attack rate of 15-100%. Control of armyworm S. frugiperda in sweet corn plants generally still use synthetic chemical insecticides because they can control pests quickly and practically. Biological control is an alternative that can be used to overcome the impacts caused by the use of synthetic insecticides. The biological agent that has the potential to control plant pests is the entomopathogenic fungi Metarhizium anisopliae (Metsch) Sorokin. The research was to obtain the concentration of the local entomopathogenic fungi Metarhizium anisopliae (Metsch) Sorokin which was able to control the armyworm Spodoptera frugiperda J. E. Smith. The research was conducted at the Laboratory of Plant Pests, Faculty of Agriculture, Riau University from June to August 2020. The research was designed a completely randomized design with six treatments local entomopathogenic fungi concentrations M. anisopliae 0 g.l-1 water, 10 g.l-1 water, 20 g.l-1 water, 30 g.l-1 water, 40 g.l-1 water, 50 g.l-1 water and four replications, in order to obtain 24 experimental units. The results showed that the use of the entomopathogenic fungi M. anisopliae (Metsch) Local Sorokin with a concentration of 30 g.l-1 water contains a conidia density 0.65 x 108 con.ml-1 is a concentration capable of controlling the armyworm S. frugiperda with a total mortality of 82,50%, initial time of death 33,75 hours after application with a lethal time of 50 81,70 hours after application.
