Abstract

The present invention provides a compound for controlling wood parasitism pest as well as a method for preventing wood parasitism pest. That is the present invention provides a compound containing O-ethyl-S-propyl[(2E)-2-(cyano-imino)-3-ethyl-1-imidazolealkyl]thionophosphonates as active component, a method for controlling the wood parasitism pest using said compound, as well as a method for protecting wood using said compound.

Description

technical field [0001] The present invention relates to O-ethyl-S-propyl[(2E)-2-(cyanoimino)-3-ethyl-1-imidazolidinyl]phosphonothioate (common name: imicyafos: thio A phosphonate nematicide) as an active ingredient of a composition for controlling parasitic pests of trees, a method for controlling the pests, and a method for protecting trees. Background technique [0002] Patent Document 1 discloses that organophosphorus compounds containing thiophosphonate imicyafos are useful as active ingredients of insecticides, acaricides, and nematocides, but there is no specific description on the control of pine wood nematodes. Patent Document 2 discloses (-) optical isomers of thiophosphonate imicyafos and their usefulness as pest control agents, wherein, as plant parasitic nematodes, pine xylophilus is exemplified, however, for their Prevention and treatment did not see specific records. [0003] Patent Document 1: U.S. Patent No. 5,405,961 [0004] Patent Document 2: JP-A-2003-...
