Gold Spotted Oak Borer (GSOB)

Systemic Dinotefuran Spray

This will ONLY control adults feeding on the leaves for three months. It will not target larvae or eggs. You can purchase and apply this by following the links and directions below (highlighted words are links to purchase sites). For those who would rather leave it to the professionals, Precision Tree Experts can perform these treatments for $75.00-$300.00 depending ton the size of the tree.

  • Dinotefuran (one quart makes two gallons of material)                                              Note: This is a neonicotinoid. If used incorrectly and against label instructions this pesticide has been reported to be dangerous to bees.  Neonics are great tools for responsible hands. Not unlike a wrench or a hammer, which if used incorrectly could also kill bees.

  • Pentrabark (6 oz. per quart of Dinotefuran)

  • Two gallon sprayer

  • Nitril Gloves

  • Safety Glasses

  • Long sleeve shirt and long pants

  • Shoes and socks

  • Soaker hose 

Step 3: Timing

Best uptake happens three to four days after a good rain, on breezy days with temperatures from 65-75 degrees Fahrenheit. Studies suggest the best time of year for treatment is in May or June. I have had success treating Oaks after supplemental irrigation with soaker hoses. The hoses run overnight for one night two days prior to treatment. Please consult an irrigation specialist for help setting up your system.

Step 4: LOOK FOR NEARBY FLOWERING PLANTS THAT COULD BE IN THE PATH OF MATERIAL DRIFT. THIS PRODUCT CAN BE HAZARDOUS TO HONEY BEES IF MATERIAL IS ALLOWED TO SETTLE ON FLOWERS OR OTHER BEE FORAGING SITES. AVOID TREATING THOSE TREES OR SET UP A BARRIER TO PROTECT NEARBY FLOWERS. This is bark applied systemic insecticide. If applied correctly, there is NO RISK TO BEES.

Step 5: Spray lowest 4 feet of trunk on trees with solution (One quart of Dinotefuran and 6 oz of Pentra Bark to 1.75 gallons of water)

Step 6: Repeat Step 3 annually

 

LIMITATIONS: DO NOT EXCEED 5 GALLONS OF MIXED SOLUTION PER ACRE PER YEAR. IF NECESSARY, ALTERNATE TREATMENTS ACCORDING TO SEVERITY OF OUTBREAK. DO NOT APPLY WHEN WIND OR OTHER CONDITIONS WILL MOVE SPRAY PARTICLES IN CONTACT WITH SURFACE WATER OR PLANTS IN FLOWER. IT IS UNLAWFUL TO USE ANY PESTICIDE IN ANY WAY THAT IS NOT IN ACCORDANCE WITH THE LABEL.

  • BaselineĀ® (one quart makes 100 gallons of material)                                                 Note: This is an insecticide.
