Case Studies
Crop Residue and Pest Management
Costa Rica

Overview
Costa Rica is known for being one of the leading producers and exporters of pineapple in the world.
The problem they face is that after the pineapple is harvested, the leftover residue decomposes, leading to an infestation of stable flies , in addition to farmland contaminated by agrochemicals. The conventional way to manage residues is to use herbicides and then burn or put them in the ground.

EM Application
In three pilot tests, they applied EM・1 or combine EM・1 and chemicals to crop residue.
・T4: 20L of EM・1/ha ×2
・T5: Staricide (triflumuron) + EM・1
・T7: Dimilin + EM・1

Effects and Results
・EM effect minimized the stable fly infestation
・EM helped breakdown the crop residue faster
・EM reduced agrochemicals use
Comparing the control and EM area after 10 days
