In 2020, a field experiment was started to look at the combined impacts of biological control and herbicide on Lygodium microphyllum. At two heavily L. microphyllum invaded sites with high mite and moth activity, we established 5x5m plots (72 plots total) that received an herbicide treatment (no treatment, treat in Year 1, treat in Years 1 and 2; 2% Garlon 3A, active ingredient triclopyr) and a pesticide treatment (untreated or treated to exclude agents every 4-6 weeks; Bonide Systemic Insecticide, active ingredient acephate). 10 ft tall trellises simulating trees in the field to measure the ability of L. microphyllum to grow with and without agents. Permanent quadrats were also installed within the plots for monitoring L. microphyllum cover. Additionally, these quadrats were used to quantify Neomusotima conspurcatalis damage.
