ABSTRACT OF THE DISCLOSURE This invention is directed to a unit dosage system for tree trunk implantation to control insect pests afflicting trees in which a plurality of vertically spaced apart holes (about 10-15 cm) preferably 10 holes, are drilled into the trunk and the holes are filled with about .1 to 2.0 gram unit dosage weights (as 100% active ingredient) of N-Acyl phosphoroami- dothioates in a sap soluble capsule such as disclosed in Jenson U.S. Patent 3,706,161. In the preferred embodiments the active compounds are O-methyl or ethyl S-methyl or ethyl N-acetyl- phosphoroamidothioate which technically pure (over 80%) and whose method of preparation is shown in Magee U.S. Patent 3,716,600. A feature of the system is the provision of 10 prepackaged tree medication capsules loaded with the active compound in a double or triple package within a package, each package being hermetically sealed to permit storage and ship- ment without giving off hazardous vapors. The inner package is a heat sealed metal foil lined package hermetically enclosing 10 capsules of the Jenson structure. The outer package containing instructions can be read before opening the inner package containing the capsules. Thus the user prepared by reading the instructions can quickly and efficiently make the necessary spaced vertical drillings, insert the capsule loaded with the highly effective agent, seal the opening with tree dressing and provide protection against citrus blackfly, Jeffrey pine needleminer, Western spruce budworm, Zimmerman pine moth and the like. The protection is effective for two to three months in heavily infested forest areas or orchards.
