Urban Ag Pest Updates: Cabbage Whitefly

March 9, 2022


If you are an urban farmer in NYC and you see tiny white creatures fluttering around your brassicas, or little yellowish larvae stuck firmly to the undersides of your kale, collard, and broccoli leaves, there's a good chance you are looking at cabbage whitefly. This pest, resembling a very small moth but more closely related to aphids, is a relatively new species in our region, but for many NYC urban farms it's already the top brassica pest.

In this lunch session, CCE Urban Agriculture Specialist Sam Anderson will give an overview of what we know about cabbage whitefly, including how to recognize it early. We will see what has and hasn't worked for other urban farmers, and we will talk through some strategies you can try this year, leaving plenty of time for Q&A and farmer-to-farmer sharing. This is a free event!
