RESEARCH PROJECT #2

GARLIC PEST RESEARCH PROJECT

2014 - 2016

Having established size of Leek moth populations and where they are located from previous summer’s documentation by local growers, a three year project funded by Agricultural Adaptation Councils -Growing Forward 2 Fund was applied for.  Upon receiving the grant the project was expanded to encompass Bulb and Stem nematode concerns by local growers.  Additional funding was granted by the Haliburton County Development Corporation.

Project Objectives

1. Monitor leek moth and carrion moth in wild leek patches

2. Document the natural enemy complex at garlic sites with high leek moth populations

3. To determine the impact of garlic bulb and stem nematode on garlic growers in the region, and test effectiveness of different crop cover treatments in reducing soil nematode populations integrated with planting nematode-free or “clean” garlic seed.

Project Updates

Leek moth:

1. A total of 7 sites (4 wild leek and 3 garlic) were monitored in 2014 for leek moth from May to September.  Daily temperature and rainfall was also recorded at each site.

2. Data on garlic crop damage and the natural enemy complex was also collected throughout the growing season.

3. Leek moth and natural enemy samples will be verified by a taxonomist at AAFC.


Bulb and Stem Nematode:

1. A site with established nematode populations was selected for the cover crop experiment

2. We experienced some challenges with the cover crop seeds germinating, thus extending the timeline for this work into 2015-2016.

3. To ensure that the field experiments are successful we are currently conducting germination trials for each cover crop (e.g. pearl millet & ornamental mustard) with help from students at the Fleming College Frost campus (Lindsay).
