The Efficacy of Several Types of Organic Pesticides against Mortality of Armyworm (Spodoptera frugiperda)

Abstract:

Armyworm (Spodoptera frugiperda) is a pest on several food crops including soybeans and corn. Armyworm control still emphasizes the use of resistant varieties and insecticides. Alternative efforts are needed to use more environmentally-friendly control methods, including the use of organic pesticides from biological materials. The control of Spodoptera frugiperda was carried out by testing the application of several types of organic pesticides at the same concentration of 50%. The purpose of this study was to determine the type of pesticide that was most effective in reducing mortality and attack from Spodoptera frugiperda. The study was started by doing mass propagation of S. frugiperda larvae, S. frugiperda larvae investment, and mortality test. The test used the Randomized Block Design (RBD) method using several organic pesticides consisting of five treatments, namely P0 (control), P1 (tobacco), P2 (shallot), P3 (garlic), and P4 (papaya leaves), P5 (blimbing wuluh leaves), P6 (Jatropa curcas fruit), P7 (lemongrass). The results of the application of organic pesticides on the mortality and attack rate of S. frugiperda had a significant effect. Organic pesticides that are most effective in reducing the mortality and attack rates of S. frugiperda are pesticides made from tobacco (Nicotiana tabacum). At a concentration of 50% organic pesticides made from tobacco can reduce the mortality of S. frugiperda up to 100%. Tobacco-based pesticides also received the lowest land attack rate at 46%. Organic pesticides applied to S. frugiperda larvae also affect the growth of S. frugiperda pupae.
