Here’s the photo from last year.
Same question this year, lol! Would prefer to use the Sumithion pesticide I still have left. Waste of time?

Edit: found my previous thread about Permethrin:

Permethrin as a one-stop peach tree pesticide?

Alan, the facts are that not all pyrethroids have the same chemical and environmental characteristics. In my view, IF a consumer wanted to choose a pyrethroid I’d recommend consumer-grade Cyfluthrin. On the other hand, IF they were more open to different choices I’d make a recommendation more specific to their crops, ecology, and pests.
