Abstract

Spodoptera frugiperda is an important pest on maize. The purpose of this research were to determine the pathogenicity of Beauveria bassiana and Metharizium sp in Fall armyworm (S. frugiperda) larvae, to determine the effective concentrations of B. bassiana and Metarhizium sp. to control  Fall armyworm (S. frugiperda), and to determine the time span of B. bassiana and Metarhizium sp infection which is effective for controlling Fall armyworm (S. frugiperda). This research was conducted at the Pesticide and Natural Materials Laboratory, Faculty of Agriculture, Universitas Muslim Indonesia, Makassar, UPTD Balai Proteksi of South Sulawesi and Corn Planting in Galung Village, Barru District. Barru Regency. The research start on April to October 2020. The research used a Fully Randomized Design (FRD) with 2 factors and three repetition. The first factor was the type of fungus (Metarhizium sp and B. bassiana) and the second factor was the density of conidia (10⁶, 10⁷, 10⁸ and 10⁹ conidia/ml). The results showed that the type of fungus and the density of conidia were significantly different for all observed variables. The pathogenicity of the fungus B. bassiana was better than Metarhizium sp and the density of conidia (concentrations) of both B. bassiana and Metarhizium sp. were significantly different from those of S. frugiperda larvae, but the density of conidia (concentration) 10⁹ was faster infected and killed S. frugiperda larvae. The Symptoms of entomopathogenic fungus attack on S. frugiperda larvae are sluggish movement, turning pale in color, decreased appetite, gradually silence, and death. The dead larvae are hardened and slightly blackened.

Abstract

This study aims to determine the effect of giving various concentrations of cow bio urines on the growth and yield of mustard plants grown on bed media. This research was conducted in Samaulue Village, Lanrisang District, Pinrang Regency, South Sulawesi Province. This study took place from December 2021 to February 2022. The study used a randomized block design consisting of 3 levels of treatment, namely 150 ml/liter, 250 ml/liter, and 300 ml/liter, and treatment without urine. Each treatment was repeated three times to get 12 experimental units. The results showed that using a concentration of 250 ml/liter cow urine fertilizer could increase the growth and yield of mustard plants. The average plant height was 38.98 cm, the wet weight of the plant was 235.67 g, the dry weight of the plant was 23.67 g and the consumption weight was 234.33 g.
