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.

The invention relates to an efficient insecticide composition for killing agricultural pests. The efficient insecticide composition comprises the following components in parts by weight: 10-50 parts of fenvalerate, 20-40 parts of fipronil and 20-60 parts of chlorfenvinphos. The efficient insecticide composition disclosed by the invention has a remarkable synergetic effect, is capable of reducing the consumption of active ingredients, lowering the use cost, delaying the generation of pest resistance to insecticides, and effectively reducing the environment pollution and pesticide residue, and has a remarkable effect of killing pests such as cotton bollworm, cabbage caterpillars, oriental tobacco budworm, tea hair-4 bean-pod borer, noctuid moths, budworm, leaf miner, pyralid moths, caterpillars, slug caterpillar moths, inchworm, cotton geometrid, phytophthira, leafhoppers, plant hoppers, stinkbug, locusts and leaf-eating coleopteran; meanwhile, the damage to the environment can be reduced.

The invention discloses a plant pesticide, and belongs to the technical field of agriculture, and the plant pesticide comprises the following raw materials by weight: 1-2 parts of Tephrosia purpurea,80-120 parts of water, 0.5-0.7 part of soap, and 0.1-0.3 part of pepper flakes. The plant pesticide can control cabbage webworm, cabbage caterpillar, daikon leaf beetle, Aulacophora femoralis, aphid and red mite and all soft insects, and the plant pesticide has the characteristics of being green, pollution-free and low cost, and is suitable for popularization and application.

The invention discloses a water suspending agent containing bifenthrin and fluxapyroxad and a preparation method and application of the water suspending agent. The water suspending agent is prepared from the following components in percentage by weight: 20 to 60 percent of bifenthrin, 5 to 25 percent of fluxapyroxad, 2 to 10 percent of a dispersing agent, 1 to 10 percent of a wetting agent, 0.1 to1 percent of a defoaming agent, 3 to 8 percent of an anti-freezing agent, 0.1 to 1 percent of a preservative, 0.1 to 1 percent of a thickening agent and the balance of water. According to the invention, bifenthrin and fluxapyroxad are compounded and prepared into the water suspending agent, the water suspending agent has the advantages of remarkable pesticide effect, high suspension rate, safety,low toxicity and the like, the water suspending agent is used for killing pests such as grubs, cotton bollworms, cotton red spiders, thrips, wireworms, flea beetles and leaf beetles and has good prevention and treatment effects on various diseases such as potato black scurf, wheat sharp eyespot, rice sheath blight disease, sclerotinia sclerotiorum, wheat loose smut, wheat stink smut, corn leaf blight and corn head smut, and compared with a single agent of bifenthrin and fluxapyroxad, the water suspending agent has the advantage that the insecticidal and disease-preventing effects are obviously improved.

The invention discloses a tree trunk injection agent for preventing and controlling diseases and insect pests of excentrodendron hsienmu, wherein the tree trunk injection agent is prepared from the following components in percentage by weight: 0.55-0.8% of lemon grass extract, 0.05-0.25% of gamma-polyglutamic acid, 1-3% of nano carbon, 15-18% of formamide and the balance of purified water based on100% as a total. The components are mixed and stirred and then dissolved till transparency. The tree trunk injection agent is used in the following way: selecting excentrodendron hsienmu with a diameter greater than 15cm, injecting the tree trunk injection agent at 20-30cm from the base part of the excentrodendron hsienmu stem, and inserting a syringe needle of tree trunk injection agent into thexylem part of the trunk obliquely from top to bottom; after the injection, observing the flow rate of the tree trunk injection agent; after the tree trunk injection agent completely enters the tree body, pulling out the syringe needle, blocking the wound with mud, and letting the wound heal naturally. According to the tree trunk injection agent disclosed by the invention, the tree trunk injectionagent is injected into the excentrodendron hsienmu body through a trunk injection way, the diseases and insect pests are prevented and controlled through conduction of the tree body, and a good effect is realized on anthracnose, leaf beetles and leaf rollers; compared with traditional application way, the trunk injection way saves water and labor and is pollution-free.
