Can garlic mustard be treated with spot foliar spray?from extension.psu.edu
Preemergent herbicides lose efficacy quickly and are nonselective, making them a poor choice of treatment. Treating during the rosette stage with spot foliar spray is a more targeted approach and can be done anytime during the basal year. Foliar applications can be applied anytime the aboveground temperature is above freezing. Applying in the late fall through winter and early spring of the basal year avoids accidental overspray on nontarget species.

Quotes
Life cycle
- Garlic mustard has a biennial life cycle, meaning that it completes its life cycle over a two-year period. Seedlings germinate in the spring and form into basal rosettes -a low cluster of heart-shaped leaves by midsummer. Immature plants will overwinter as rosettes that stay green and continue to photosynthesize during periods when temperatures are above freezing giving them …
Reproduction
- All plants that survive the winter produce flowers in their second year and then die. An average plant produces 400-500 seeds that germinate readily in both well-lit and shaded environments. In the following spring, the garlic mustard will shoot straight up into a tall, slender flower with clusters of small white, four-petal flowers. Since the plant only flowers in the second year, the pl…
Prevention
- Eradicating garlic mustard is easy work, but takes time. Lots of time. Vigilance is key, as garlic mustard can sprout up even when you're sure that you've gotten rid of every last one. The ultimate goal in removing garlic mustard is to prevent seed development and spreading until the existing seed bank is depleted. Unluckily for us, this may take 2- 5 years in any confined area. Cutting th…
Preparation
- It's important to know when pulling garlic mustard you should always make sure that the taproot is completely removed or the plant will re-Garlic mustard its sprout. All cutting should be bagged, dried and then burned or buried deep into the ground. Contact your local landfill to see whether or not they will do this for you.
Management
- Controlled burns or herbicides may be needed in larger areas as way to lower labor costs. Both methods have potential drawbacks. Fire for instance can be ineffective if too cool or too hot. Fire that is too cool may not have an effect on the plant removal; instead it may just increase the presence of garlic mustard. Fire that is too hot can change the composition of the soils top layer…
Treatment
- The method you choose depends on the size of garlic mustard infestation you have, and the type of environment the plant has invaded. Regardless of method, eradication should always take place before seed development.
