Studying Biocontrols for Root Aphids

Examining the efficacy for two classes of biocontrols on root aphids.

Intro & Overview

This study was conducted by the Cannabis Horticultural Association and examined the efficacy of two different classes of biocontrols for root aphids on cannabis.

  1. Predatory Nematodes- (Steinernema feltiae) & (Heterorhabditis bacteriophora)
  2. Myco-insecticide- Beauveria bassiana

Companion Planting for Cannabis

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.

Biodiversity and Pest Management in Agroecosystems

This book is an important contribution to the literature on ecologically based pest management. In addition to reviewing relevant aspects of ecological theory and the broader agroecological context of pest management, it presents numerous data sets and case studies from both temperate and tropical farming systems.

Biodiversity and Pest Management in Agroecosystems reflects the authors’ many years of experience, particularly in the chapters on insect management in multiple cropping systems, insect ecology in orchards containing cover crops, and non-crop vegetation effects on insect populations in crop fields.

Company Spotlight – Parabug

Parabug uses unmanned aerial vehicles, “drones”, for the rapid dispersal of biological controls such as predator mites to cover larger areas more rapidly.

Biological control with natural enemies is a technique often used in combination with other practices. University of California Agriculture and Natural Resources defines the ecosystem-based strategy of Integrated Pest Management as “a combination of techniques, such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties.” 

With organic farming on the rise, many producers are implementing these eco-friendly techniques.

Eastern Washington Farm Goes Green on a Commercial Scale

Walden Cannabis takes advantage of its massive property by reserving thousands of square feet for insectary beds and cover crops.

The farm’s size also allows Walden to utilize a system of crop rotation — somewhat of a rarity in the cannabis space. After each harvest, the company rotates its grow site to a new section of the property in order to maintain healthy soil….

Pest Alert – Cannabis Aphid

The Oregon Dept of Agriculture has detected a new pest species for cannabis.

Phorodon cannabis, known as the cannabis aphid, bhang aphid, or hemp aphid, feeds on cannabis. It is only known from two locations in Oregon (Portland and Estacada) at this time, but it is very likely that it is established and unrecognized at other facilities. The pest is established in much of Europe and Asia, North Africa, and it is known from Colorado in North America. It appears to be a recent arrival in Oregon, and it is in the interest of all growers of cannabis to slow its spread.
