Abstract

Spodoptera frugiperda is an invasive insect and includes a highly polyphagous insect that can attack various types of plants. Armyworm attacks can be a severe threat to corn farmers. It can cause significant yield loss. This study aims to determine the attack intensity and distribution of the S. frugiperda armyworm in several sub-districts on several varieties of maize in Takalar Regency, South Sulawesi, as the first step in determining an appropriate control strategy. The results showed that from the five sub-districts where the observations were made, there were symptoms of S. frugiperda attack, namely in the sub-districts of South Polongbangkeng, North Polongbangkeng, Sanrobone, South Galesong, and Pattallassang. The highest attack intensity was around 97.33% of 4 weeks in Pallantikang Village, Pattallassang District. The lowest attack intensity, namely 46.44% of 3 weeks, was found in Kadatong Village, South Galesong District.

Abstract

Endophytic fungi have the potential as biocontrol agents against bacterial leaf blight caused by a Xanthomonas oryzae pv Oryzae to support environmentally friendly agriculture. This study aims to select endophytic fungal isolates that have the potential as biocontrol agents against bacterial leaf blight. This research was divided into 3 stages: 1) isolation and rejuvenation of endophytic fungi isolate; 2) antagonistic test of endophytic fungi isolates against Xoo bacteria in vitro; 3) in vivo test of endophytic fungi isolates which are antagonistic in rice plants. As many as 16 isolates of endophytic fungi were isolated and rejuvenated, 6 isolates of endophytic fungi were antagonistic in vitro tests, the application of endophytic fungi isolates on rice plants was able to increase the resistance of rice plant highly susceptible, susceptible, moderately susceptible to moderately resistant, moderately susceptible and susceptible.
