The invention discloses a
tree trunk injection formulation for preventing and treating diseases and
insect pests of canarium kipella trees. The
tree trunk injection formulation consists of the following raw materials in percentage by weight: 2.0-4.0% of a lemon-grass extract, 5.0-10.0% of a
ligusticum wallichii extract, 1-3% of
nano carbon, 15-18% of
formamide and the balance of pure water till 100%. The raw materials are mixed and stirred and distilled till being transparent. A use method of the
tree trunk injection formulation comprises the following steps: injecting the
medicine into a partwhich is 20-30cm away from the root base of a canarium kipella tree of which the
diameter is greater than 10cm, inserting a tree
trunk injection formulation needle into the
xylem of the
trunk in an inclined manner, observing the flow of the tree
trunk injection formulation after injection, after the tree
trunk injection formulation is completely injected into the trunk, pulling out the needle, plugging the wound with soil, and healing the wound naturally. Due to the tree
trunk injection mode, the tree
trunk injection formulation is injected into the canarium kipella tree, diseases and insectpests of the canarium kipella tree can be prevented and treatment through conduction of the tree trunk injection formulation in the tree self, a good effect on anthracnose, leaf beetles and leaf rollers can be achieved, and compared with a conventional mode, the tree trunk injection formulation is low in
water consumption, good in labor conservation and free of
pollution.
