Effect of three fungi species application and concentration on production and pest attack on shallot (Allium ascalonicum L.)

Abstract

This study aims to determine the influence of three types of beneficial fungi with various concentration of application on shallot production and pest attacks. This research was carried out at the Plant Disease Laboratory and Teaching Farm, Faculty of Agriculture, Hasanuddin University, from September to November 2022. This research was arranged in a split plot design. The main plots are three types of fungi, namely Trichoderma asperellum, Beauveria bassiana and Metarhizium anisopliae, while the plot consists of concentration consisting of 0, 7, and 14 g/L. Results showed that there was no interaction that had an influence on production, bulb moisture content, production per hectare and the percentage of Spodoptera exigua attacks. The highest production per hectare was recorded in the Beauveria bassiana treatment of 15.97 tons. The application of the fungus at a concentration of 14 g/L producing the lowest weight loss of bulb 3.17%, production per hectare of 17.27 t and the lowest percentage of Spodoptera exigua attacks was 6.19%.
