Japanese Beetles

Japanese Beetles have arrived in the Twin Cities.  For quick knock down use Spinosad or Carbaryl.  For longer term effect try deltamethrin or bifenthrin.

To kill grubs apply a good grub killer to your lawn between July 15th and Aug 1st.  For best results dethatch lawn first then water grub killer in after application.

Japanese Beetles

Found first Japanese Beetle today. Right on time in comparison to past five years. Will monitor to determine if JB’s become an issue. If so will treat with bifenthrin and deltamethrin.

Final Nitrogen Fertilizer

Between now and August 15th is the time to apply your final nitrogen containing fertilizer to your roses.  Application before the 15th gives the fertilizer time to work without encouraging new growth that will not have time to harden off before winter.

Got Blackspot?

Got blackspot?  Try spraying with a combination of Maneb (Manzate or Mancozeb also work) with tebuconazole (Bayer Advanced Disease Control for Roses, Flowers & Shrubs Concentrate).  Not Bayer 3 in 1.  Spray at 7 to 10 day intervals to avoid possible phytotoxic effects such shortening of internodes.  Use only as directed!

Bayer Advanced Disease Control for Roses, Flowers & Shrubs Concentrate is available from Amazon.com and DoMyOwnPestControl.com. There may be local sources to the Twin Cities, but I have not found any in the East side of the Twin Cities.
