Examining the Management of Ecological Habitats for Beneficial Insects

Background

With a growing concern for eliminating pesticide residue in cannabis, farmers are learning to incorporate beneficial insects into their Integrated Pest Management (IPM) methodologies. Along with this IPM comes the potential to integrate the habitats for these insects, which ultimately decreases a dependency of purchasing them. Regenerative and biodynamic management are now amalgamating with IPM, helping us develop new insight for the complexity of running these systems. This article will attempt to encompass the broad concepts of companion planting beneficial insects and discuss the caveats of landscape management for these integrated ecosystems.
