Project was designed to identify what kind of pest problems garlic growers in Haliburton County were experiencing. The Leek Moth was chosen because it feeds on the leaves of garlic plants and affects the growth of the bulb below ground.
Use of a field-based approach to monitor the leek moth lifestyle and estimate abundance, using a well-developed protocol that relied on data collected from pheromone traps along with daily temperature readings to determine leek moth flight periods, degree-day development across the moth’s lifecycle, and seasonal abundance.
Plant damage assessments were also conducted throughout the growing season to measure the impact of leek moth on garlic crops, as well as the effectiveness of floating row covers as an inexpensive and chemical-free method of control.
The research documented a well-established leek moth presence in Haliburton County.
The information gathered was extremely useful to growers, as it will enable them to adopt and implement management strategies that target specific life stages of the moth.
Results from the row cover test areas showed that damage was reduced in covered garlic patches, thus encouraging continued use of this tool by garlic growers.
THIS PROJECT introduced garlic growers in the County to an INTEGRATED PEST MANAGEMENT (IPM) approach for managing leek moth and provided them with the appropriate tools for implementation. The IPM approach is informed by the biology of the focal pest to ensure practical and effective management practices. Participating growers had the opportunity to engage in hands-on training sessions, apply new found skill sets to improve crop management and engage with OMAF and AAFC scientists.
