ABSTRACT

Corn is the second food crop after rice which contains carbohydrates, protein, oil, water, vitamins and thiamine. Corn is also used as animal feed ingredients and industrial raw materials. Efforts to increase maize are still experiencing problems, including pests and diseases in the field. The main pest that attacks corn plants is Spodoptera frugiperda. S. frugiperda pest control can be carried out by using vegetable insecticides from remaining harvest red ginger plants (Zingiber officinale var. Rubrum). The aim of the study was to obtain an effective concentration of red ginger filtrate on the mortality of the corn armyworm S. frugiperda in the laboratory. The research was carried out at the Laboratory of Plant Pests, Faculty of Agriculture, University of Riau. The study was carried out experimentally using a completely randomized design (CRD) consisting of 5 treatment concentrations, with 4 replications to obtain 20 experimental units. The treatment given was red ginger filtrate concentration with a concentration of 0 ml.l-1 water, 25 ml.l-1 water, 50 ml.l-1 water, 75 ml.l-1 water, and 100 ml.l-1 water. The results showed that the administration of red ginger filtrate with different concentrations had a significant effect on the mortality of the corn armyworm S. frugiperda. a concentration of 100 ml.l-1 water is an effective concentration for controlling S. frugiperda larvae because total mortality of 85% with an initial death time of 21.50 hours after application and a lethal time of 50 at 54 hours after application. The correct concentration of red ginger filtrate to kill 50% of S. frugiperda larvae is 2.32% or the equivalent of 23.2 ml.l-1 water.

Keywords: Spodoptera frugiperda J. E. Smith, Zingiber officinale Var. Rubrum, a botanical pesticide, armyworm.
