- Applied in spring, the treatment will provide season-long control of many insects, such as Aphids, Bagworms, Budworms, California Oakworm, Cankerworm, Case bearer, Citrus black fly, Elm Leaf Beetle, Gypsy Moth, Leaf miners, Thrips, Whitefly and more.
- The sap flow dissolves the chemical and carries it throughout the tree in 4 to 5 days. Five implants will effectively treat up to a 7″ ornamental trunk diameter
- Systemic tree implants for control on ornamental tree pest that are listed by manufacturer
- Contains 99 percent acephate, a highly effective systemic pesticide. its a broad spectrum pest control. Not recommended for edible trees such as citrus, stone fruits, etc.
- Acecaps are registered for use against aphids, bagworms, bronze birch borer, gypsy moth, tent caterpillar, wooly adelgid, and many more
- Easy to install; 5 implants per pack
- 3/8-inch diameter implant
Required Tools: • Electric or rechargeable drill, using a sharp spiral drill bit. (Always refer to package in use for recommended drill bit size – 1/4″, 3/8″, or 1/2″) • Hammer • Flat end punch, or dowel rod.
Calculation and Application of Tree Implants: (Read through instructions in their entirety prior to use) 1. Calculate the Circumference of the Tree: To find the circumference, use a tape measure around the tree trunk at 4 ft. above ground. The number of implants required is based on the tree trunk size at 4 ft. above ground and the specific recommendations for the product being used. Measure circumference in inches.
2. Calculate the Number of Implants Needed: Divide the circumference by the recommended spacing for the product being used (3, 4 or 6 inches). If tree base is larger than measured circumference, make sure to place recommended number of implants evenly around the tree base.
EXAMPLE: 40 inches circumference ÷ 4 inches implant spacing = 10 implants
3. Calculate Drill Hole Depth: The holes need to be deep enough to allow each implant to be recessed just inside the inner bark. Hole depth is determined from inside the inner bark. For proper drilling depth:
Recommended Size of Implant Diameter
Drill Each Hole Depth
1 1/2″ – 3″ (3.8 – 7.6cm)
“Mini” 1/4″ (.64cm)
3″ and up (7.6cm and up)
“Standard” 3/8″ (.95cm)
1 1/4″ (3.2cm)
8″ and up (20.3cm and up)
* “Super” 1/2″ (1.27cm)
1 1/4″ (3.2cm)
4. Gauging Drilling Depth: After drilling the first hole, use a measuring instrument (i.e. flat end of pen or pencil) as a depth gauge, insert completely into the hole and mark the depth by placing your thumb against the outer bark.
Be sure to remove drill shavings from each hole. Repeat this procedure for every drilled hole.
5. Application of Tree Implants: Drill the implant holes at a uniform spacing, spiraling up and around the lower tree trunk surface. Start approximately 6 inches (15.2 cm) from the soil level.
6. Inserting the Tree Implants: Place the implant cartridge into the pre-drilled holes, simply pressing them into the tree trunk. Be sure to press the cartridges in as far as possible. Using a hammer and a flat end punch or dowel rod carefully drive the cartridge into the tree, recessing the large end slightly beneath the cambium surface, which is just below the bark.
7. Wound Dressing: The cartridge head securely plugs the small wound made to the tree trunk, however on thin barked trees (i.e. birch, fichus, etc.) it is recommended that a light wound dressing be applied over the implant site. This provides further protection until the cambium closes over.
8. Completion of Application Process: With the application process completed the natural sap flow will “systemically” absorb the chemical and distribute it throughout the tree. The active layer of cambium will soon grow over and close the implant site. The cartridges are to be left inside the tree.
Notes: 1. Where lower branching occurs 4 feet or less from the ground, make certain the implants are placed directly beneath the lower branches. This will assure adequate distribution of chemical throughout the tree.
2. On large trees where there is no main stem or trunk and multiple branching occurs, treat each stem as if it were a separate tree. This will assure adequate distribution of chemical through the tree.
3. When Re-treatment is necessary, place the new implants in a spiral pattern between, and above or below the previous treatment. Do not attempt to drill into and remove the cartridges implanted previously. Note the positioning of three applications.
Follow Cautions Where Indicated:
• Always read & follow label directions for product being used.
• Use proper drill bit
• Remove shavings from hole
• Recess cartridge end below the inner bark
• Sterilize the drill bit (using Lysol aerosol, or similar type, disinfectant) between trees being treated
• Water thoroughly if weather conditions are dry
• Carefully read the Application Timing for optimum results
• Enlarge the hole diameter
• Use a sharp end punch
• Remove the previously implanted cartridges
• Break plastic gelatin
• Place implant too deep
