摘要： An apparatus is disclosed for injecting liquid chemicals directly into the trunk of a tree with the apparatus having a tapered, wedged-shaped needle on the end of an injection tip which is detachably secured to an injector. The injection tip includes a spring-loaded valve which is opened when the injection tip is secured to the injector to permit the chemical to flow therethrough. After the injection needle has been injected into the tree, the injector is disconnected from the injection tip. After a predetermined length of time has expired, the operator may manually open the valve to determine if the liquid chemical pressure within the tree has diminished to enable the injection tip to be removed from the tree.
