Description

An initial laboratory phase was aimed at comparing the efficacy of two parasites T. brassicae and T. ostriniae on leek moth. The purpose of a second, two-year phase, conducted at the Organic Agriculture Innovation Platform in Saint-Bruno-de-Montarville, is to test the ability of both parasites to reduce leek moth damage in the field compared to a control. A technical and economic analysis will look at the costs and benefits of trichogramma releases.

Objective(s)

  • Determine in the lab and the field the capacity of two species of trichogramma wasps raised commercially in Québec (T. brassicae and T. ostriniae) to parasitize leek moth eggs and reduce larval populations and the damage they cause on organic leeks
  • Develop a cost-effective, ecofriendly control strategy that protects natural enemies

From 2015 to 2019

A comparative study of organic fertilizers with a high, effective nitrogen to total phosphorus ratio (Neff / Ptot) as a basis for developing productive and sustainable market gardening fertilization strategies

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
