Apples are at green tip. Time for copper and oil sprays, continue chopping leaves, and fertilizer and herbicide applications can begin anytime...and set your green tip biofix if using NEWA or RIMpro.

SLF, Invasive insect

Connecticut has established Spotted Lanternfly populations in both West Haven and Greenwich. Both locations are close to Long Island NY, which announced its own established SLF population on August 14, 2020.

Good news: MA does not, as of September 23, 2020,  have a known established population of SLF.

Bad news: both CT populations are located at or near main highway routes that lead directly to MA. 

What you can do: Remain vigilant! If you spot SLF please report it with as clear a picture(s) as you can manage. Report findings using the fact sheet found at this link: Spotted Lanternfly Fact Sheet and Reporting
