Conifer Bark Beetle Abacide (Abamectin) Study

Abacide 2: Three Ips trials evaluated the duration of 1) two high rates (0.4 and 0.8 g AI/inch DBH) of abamectin in 2008-2011; 2) three lower rates (0.4, 0.2 and 0.1 g AI/inch DBH of abamectin after application in fall 2010 or spring 2011; and 3) azadirachtin (Aza-Sol®) and dinotefuran (Safari®) applied via bole spray, soil drench, or trunk injection in spring 2011.

Some Internal Effects of Mauget Tree Injections

BY: Dr. Alex Shigo, Walter  E. Money  and Dale I. Dodds
Journal of Arboriculture 3(11): November 1977

Negligible amounts of discolored wood and cambial dieback were associated with control Mauget injection wounds made 1 year earlier on redmaple, white oak, and shagbark hickory. Injured tissues associated with all wounds were compartmentalized in the wood present at the time of Injection; wood that formed subsequently was not infected.

Armillaria Comparison Treatment Study

A study conducted by Heather Vallier, Ph.D., Plant Pathologist, Cambria, California, comparing 1 vs. 2 annual applications of various trunk micro-injected materials to suppress Oak Root Fungus (Armillaria mellea) over a 2 year period on Blue Gum (Eucalyptus globulus).

Erythrina Gall Wasp

A study conducted by the University of Hawaii at Manoa that evaluated the chemical control of Erythrina Gall Wasp.

Efficacy of Trunk Micro-injected Dinocide on Scale Insects

A stand of many heavily infested California Pepper Trees Schinus molle (also known as American pepper, Peruvian peppertree, escobilla, false pepper, molle del Peru, pepper tree, peppercorn tree, Californian pepper tree, pirul and Peruvian mastic) located at Old Ranch Country Club, Seal Beach, California, was micro-injected at root crown level approximately 6 inches above soil level with treatments of 2ml, 3ml and 4 ml Dinocide.

Pine Resin Test…

TEST PINE TREES for Mauget Micro-Injections…

Some species of trees in the genus Pinus have very well developed resin ducts in their xylem. During much of the year these trees produce a rapid and sustained flow of resin in response to any wound in either the bark or woody issues. Injection of materials into these trees during these times has been difficult or impossible even with very low volume micro-injection capsules.

Palm Petiole Injections Study.. Fla

Palm Petiole Injections with Mauget Products have been employed successfully for decades.

It is a fast and easy method for injecting Palm trees effectively rather then into the trunk.
No damage occurs to the leaves or the trunks.
Materials such as Antibiotics, Insecticides, Fungicides and Nutrients will translocate throughout the entire tree using this method.
It is an alternative method of injecting is the bases of leaf petioles was found to be of definite
therapeutic value in diseased palms.


Dr. Robin Spitko

Arcadia, Ca – JJ Mauget Company, pioneers in the technology of tree injector systems, has announced the appointment of Dr. Robin Spitko as Chief Science Officer. Robin brings more than thirty-five years of experience working as a domestic and international research investigator for the agricultural chemical industry and universities. Robin’s extensive background includes project management and protocol design for traditional and organic agrichemicals. Dr. Spitko was chairwoman of the Government Affairs Committee, where she was responsible for coordinating legislative affairs for the National Alliance of Independent Crop Consultants (NAICC) from 1996 through 2003. Robin has also been a proven expert witness in numerous trials involving agricultural litigation. She’s provided irrefutable testimony in several cases that were resolved favorably due to her expertise.


Every regulatory decision that’s made is transitioning agriculture. It’s happening with each new decision made.

Lewis SLF Control Methods 2017-2018 Summary

Spotted lanternfly, SLF, Lycorma delicatula, a sap feeding insect native to Taiwan and China, was first detected in the U.S. in 2014. Field populations continue to expand beyond the 14 county area currently under quarantine in southeastern Pennsylvania. Severe impacts by this insect have been noted.
The current control measure being employed by state and federal cooperators against SLF is a bark spray application of dinotefuran on tree of heaven (Ailanthus), the preferred host tree. The effectiveness of this control approach is readily apparent, especially later in the year when dead SLF adults can be found piled at the base of treated trees (Fig 1).

Hudson Valley Research Laboratory

Tree injection delivery of systemic insecticide for SLF management study:
Directed trunk application has become standard practice for treating trees infested
with SLF, and employed at the Rolling Rock Stone Quarry, 40 Rolling Rock Road,
Boyertown, PA in Berks County.
Trial I. Thick barked tree species of the genus
Salix appear to be less adapted to accept directed
trunk application. Our study hypothesis that the
use of tree injection is more adept at providing
management of SLF in this tree genera.
