THE INFLUENCE OF THE VEGETABLE PESTICIA OF GADUNG TUBERS Dioscorea Hispida Dennst ON POPULATION AND INTENSITY OF ATTACKS OF Frugiperda Armyworm Caterpillars ON CORN CROPS

This research aims to determine the effect of vegetable pesticides originating from
gadung tubers (Dioscorea hispida Dennst) on the population and intensity of armyworm
(Spodoptera frugiperda) attacks on corn plants. Armyworm is one of the main pests that
often attacks corn plants, causing significant damage to agricultural products. Gadung
tuber botanical pesticide was chosen because of its known ability to control pests
naturally without causing negative impacts on the environment. This research was carried
out using an experimental method involving several doses of gadung tuber vegetable
pesticide sprayed on corn plants infected with armyworms. The results of the study
showed that the application of gadung tuber botanical pesticides could significantly
reduce the armyworm population and reduce the intensity of attacks compared to controls
without treatment. Based on statistical analysis, administering gadung tuber botanical
pesticide at certain doses provides a more effective effect in reducing armyworm attacks,
which can be an environmentally friendly alternative for controlling pests on corn plants.
This research concludes that gadung tuber botanical pesticide has good potential as a
natural control for armyworms, and can be used in sustainable agricultural systems.
Key words: botanical pesticides, gadung tubers, armyworms, Spodoptera frugiperda, corn
