Embodiment 1

[0024] The preparation of the pesticide for preventing and controlling pine wood nematode: dissolve the main drug X in the solvent S, add the additives Ai and Aj, stir well until it is completely dissolved, add a small amount of distilled water to the standard volume, and finally fill it into an injection bottle for packaging That's it. The drug dosage and configuration are shown in Table 1.

[0025] like figure 1 Shown is a schematic plan view of the injection system, which includes a plastic injection bottle 9 and an injection tube 10 . Fill the liquid medicine configured above into the plastic bottle 9 first, and then connect the injection tube 10 to the mouth of the plastic bottle 9 in a sealed manner.

[0026] like figure 2 Shown is a planar cross-sectional view of the punching machine, whose overall shape is similar to a "gun", including a punching needle 2, a needle seat 3, a gun seat 4, a gun shaft 5, a slider 6, a gun handle 7 and a rubber handle 8; The perforati...

Abstract

The invention provides a pesticide for preventing and controlling Bursaphelenchus xylophilus and an injection method thereof. The pesticide for preventing and controlling Bursaphelenchus xylophilus comprises an effective medicament X, compound auxiliaries Ai-Aj and solvent S which form an X-Ai-Aj-S system; based on preparing 1L of the pesticide, the consumption of the compositions is that: the consumption of the effective medicament X is 5 to 40g, the consumption of the auxiliary Ai is 100 to 150ml, the consumption of the auxiliary Aj is 150 to 200ml, the consumption of the solvent S is 600 to700ml, and the balance is water; and the concentration of the prepared pesticide is 0.5-4g/ml. Through experiments, the pesticide has good effect of preventing and controlling the Bursaphelenchus xylophilus, and also has good effect of preventing and controlling Monochamus alternatus Hope, Atysa marginata cinnamomi Chen, sweetgum palmerworms, Dendrolimus houi Lajonquiere, Hylobius abietis, pine bark beetles and the like; and drilling machinery provided by the invention and the injection method adopting the drilling machinery are simple and practical, do not consume fuel or electricity, and are particularly suitable to meet the requirement of preventing and controlling plant diseases and insect pests in mountain woods and forests.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide for preventing and treating pine wood nematode and an injection method thereof. Background technique [0002] Trees are tall, erect living organisms that are often affected by pests and diseases. The contiguous forests often form large-scale forest diseases and insect pests, which affect the living environment of human beings. Trees or forest pests and diseases are difficult to control due to the tall trees or the steep growth environment. At present, many control devices cannot be used in the harsh mountainous environment and cannot deliver drugs to the crown of trees to play a role; The pests are harmful in the tree, and all spraying methods are ineffective due to the blocking of the trees. Punching and injecting medicine is an ideal method for preventing and controlling forest plant diseases and insect pests. Experts in forest disease and pest control in various countri...
