Pest Update - Leek Moth

Thursday, July 5, 2018

Perennia in association with NSDA and AAFC has been monitoring for leek moth across Nova Scotia since early May this year. Leek moth is an invasive insect pest from Europe that feeds on Allium species (onions, garlic, leeks,etc), and can cause significant damage to these crops. Previous to 2018, leek moth had been identified in Kings County in 2017. In 2016 gardeners reported damage on garlic which could have been due to leek moth but no specimens were ever recovered to verify these observations. In response to this a provincial leek moth monitoring project was established, to determine how widespread the pest is in Nova Scotia. As of this week we have confirmed leek moth in both Kings and Annapolis County. Currently we have not found the pest in large scale commercial fields, and all the leek moth samples we have identified have been from garlic. Leek moth favours garlic and leeks primarily; we are currently unsure of its effects in onion production.

Leek moth can be monitored using commercially available pheromone traps, which attract adult males. The adult leek moth is a small (5-7 mm in length) brown moth with a distinctive white triangle in middle of its wings when they are folded at rest. Additionally allium crops can be scouted for feeding damage from leek moth larvae. On alliums with flat leaves (garlics, leeks) the larvae feeds on the tops and inside of the leaves, as well as bores into the center of the plant leaving noticeable frass. In alliums with hollow leaves (onions, chives) the larvae will feed internally producing translucent areas on the leaf known as "windowing". The larvae will also occasionally bore into bulbs.

There are several chemical controls registered for leek moth in garlic, leeks, and onions that can be found in the Perennia's Garlic Management Schedule, Leek Management Schedule, and Onion Management Schedule. These pesticides are most effective when eggs are present and leek moth larvae are small, so monitoring is crucial to ensure proper timing of applications. Row cover is also an effective means of protecting allium crops against leek moth, without using chemical controls.

For additional information on leek moth identification and management please consult AAFC's An Integrated Approach to Management of Leek Moth . If you think you have leek moth please contact Matt Peill, horticultural specialist with Perennia (email:, cellphone: 902-300-4710).

New pesticide registrations

Monday, April 16, 2018

Agri-Réseau is a resource available through The Centre de référence en agriculture et agroalimentaire du Québec (CRAAQ).  Every month, they publish a list of new phytoprotection registrations.  At Perennia, we are fortunate to have Mélanie Leclerc as part of our staff, and she has translated the March list of new pesticide registrations for Fruit Trees, Field Crops, Vegetables, Greenhouse, Berries, Ornamental, and "Other" (hops, hemp, quinoa, and basil), which can be found here.

From the Vegetable side, the main excitement is a few more weed control options in asparagus, Brassicas, and shallots, and some new disease management options in asparagus, kohlrabi, Brassica leafy greens, and bulb vegetables (Group 3-07A and 3-07B, so bulb onions, garlic, shallots, green onions, leeks, etc.)

Pest Management in the Hopyard

There are many factors to consider when managing pests in a hopyard: life-cycle of the organism, good Integrated Pest Management (IPM) techniques, mode of action and efficacy of the products, and pesticide application efficiency. Pesticide Points will be available.

April 5th from 2-4 pm

This workshop is designed for growers with existing hopyards and will be informative for organic, conventional, and spray-free growers.

A session will be held in-person at the Perennia offices at the Kentville Research Station (32 Main Street, Kentville, NS) OR you can join remotely from
  • The Truro Perennia offices (199 Dr Bernie MacDonald Drive, Bible Hill, NS)

Free SKU Foods Webinar

Friday, February 16, 2018

SKU Foods is hosting a free live webinar on Wednesday, February 28th at 2 pm called Secrets to New Food Product Success.  The webinar will cover:

Idea Discovery –  Scouting for good new food product ideas, screening those ideas, defining a target customer, consumer need, and developing a prototype so you can take your idea for a test drive.

C.A.R.T.: It is one thing to get a product in the market and another to keep it there.  It is your responsibility to ensure that your product sells at the retail level.  C.A.R.T helps producers/suppliers get more products, in more shopping carts, more often. 

Opportunity Validation – A minimum viable product lets you establish proof of concept and validate markets at minimal cost & risk.  You need to explore pricing, scale-up feasibility, develop USP, and define the business model.

Grow Business: Once the market launch is complete you need to create business efficiency, scale up to build capacity, build a team, manage the cash flow, continuity with marketing & sales, develop new markets and hopefully get to milk the product cow.

Market Launch - To get your new product launched you need a solid business plan, financing, marketing strategy, distribution & logistics, an understanding of your markets and a product launch action sequence.
