Onion production costs a lot especially when it is hit by a pest such as Armyworm (Harabas). That's why we need an alternative and cheap method to eradicate them. The study was conducted to determine the effectiveness of various concentrations of liquid Metarhizium anisopliae against armyworm ‘Harabas’ in onion “Red Pinoy’ variety. The experiment following the Complete Randomized Design (CRD) research design was conducted at Barangay Bayotbot, San Jose, Occidental Mindoro from December 2022 to March 2023.
The study used the experimental method of research. This study was composed of four treatments and three replications: T0=Control (No Application), T1=175 mL+1L water, T2=350mL+1L water, T3=525mL+1L water, T4=Chemical insecticide. Analysis of variance (ANOVA) in Complete Randomized Design (CRD) used in the experiment findings of the study revealed that the application of experimental biological pesticide at 525 mL+1L water had the best effect on the mortality rate of armyworms. When it comes to the number of insects repelled, T0 (Control) was revealed to have the most repelled number of armyworms. Meanwhile, when it comes to the percentage of damaged leaves the T0 (control) revealed to have severely damaged plants.
For the findings of the study, the researcher recommends the conduct of a similar study using liquid Metarhizium anisopliae on different stages of development of fall armyworm.
