Pests are a collective term for insects that directly or indirectly harm human life. Double mite mites and nematodes are harmful insects such as horticulture, flower, and tree. Typically, harmful mites such as tomatoes, strawberries, pears, apple trees, such as a very wide host range occurs more than 10 times a year, and apple trees, pear trees, apple trees, And cherry blossom cherry tree which damages cherry tree which is a broad-leaved tree. In addition, nematocides, which are typical harmful nematocides, include root-knot nematodes that reduce the absorption of moisture and nutrients by making hump on the roots of 300 kinds of crops such as carrots, watermelons, tomatoes and peppers, Nematodes, and pine trees that can be tested within three months.
As the nematicide for the purpose of controlling the nematode, there is currently an antimicrobial agent such as dazometh, bifenthrin, cadusafos, postiazate, metham sodium, morranetatrate, milbemectin, abamectin, emamectin benzoate, , Bromine series, diphenyl series, organosilicate series, amitraz series, tetrazine series, hexacyadene series, synthetic pyrethroid series, pyridazinone series, ascylurea series, antibiotics, microbial agents, thiourea series, (Crop Protection Guidelines 2012. Korea Crop Protection Association).
However, these medicines have not been developed in the domestic market, and the medicines developed and manufactured outside the country are imported, and the unit price is high, and they are packed and used. Therefore, there is a need for an economic, cost effective and effective nematode formulation for domestic pest control.
2- (1-undecyloxy) -1-ethanol is known as an aggregation pheromone emanating from the beetle and monochamus alternatus hope (A. Pajares et al., Identification and field activity of a male-produced aggregation Pheromone in the pine sawyer beetle, Monochamus galloprovincialis, J. Chem. Ecol ., 36: 570-583, 2010). Pine bark is an insect that mediates pine tree rehabilitation. Pine bark pine is a pine tree that is infected when the pine tree bark enters the pine tree and the pine bark enters the pine tree. However, it has not yet been known about an acarbicide or nematicide composition containing 2- (1-undecyloxy) -1-ethanol as an active ingredient.

In addition, when the composition was diluted to a high concentration dilution of 1,000,000X, only the composition of Comparative Example 4 (CO25) exhibited 90% or more nematicide activity.
The present invention not only provides a novel salicylic and nematicide composition containing 2- (1-undecyloxy) -1-ethanol as an active ingredient, but also provides harmful mites and nematodes that are harmful to horticulture, flower, It is a very useful invention in agriculture by controlling.
