Abstract

The Effectiveness of Metomyl Insecticide 40% to Armyworm (Spodoptera exigua Hubner) On Red Onion Plant (Allium cepa L.) in Songan Village District of Kintamani Bangli Regency



The Research of Metomyl Insecticide 40% to damage caused by armyworm (Spodoptera exigua Hubner) On Red Onion Plant (Allium cepa L.) in Songan Village District of Kintamani Bangli Regency was conducted in order to determine the percentage of damage of armyworm (Spodoptera exigua) and the relationship between the pareentage of damage and production after treated by metomil insecticide 40%. This onion tuber harvest after treatment with insecticide with 40% active metomyl.this research was done from 2016, November until 2017 January. Randomized block design was used in this studay with 5 treatments and replicated 5 times.
