PROBLEM TO BE SOLVED: To provide a pest control composition having excellent pest control efficiency against pest.SOLUTION: A pest control composition contains an oxalyl amide compound represented by the formula (I) and one or more kind selected from group (a) to group (d). In the formula (I), J1 to J4 are each independently N or CR6, R1 and R3 are each independently H, a halogen atom or the like, R2 is -R7 or the like, X is each independently -R7, -OR7 or the like, R4 and R5 are each independently H, -R7 or the like, R6 is H, a halogen atom or the like, R7 is a C1-C6 chain hydrocarbon group substituted/unsubstituted by one or more halogen atom, R9 and R10 are each independently H or the like. The Group (a) is the group consisting of an insecticidal active ingredient, a miticidal active ingredient and a nematocidal active ingredient. The group (b) is a sterilizing active ingredient. The group (c) is a phytotoxicity mitigation ingredient. The group (d) is a plant growth adjustment ingredient.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】有害生物に対する優れた防除効力を有する有害生物防除組成物を提供する。【解決手段】[1]式(I)で示されるオキサリルアミド化合物と、群(a)~群(d)より選ばれる1種以上の成分とを含有する有害生物防除組成物。[J1~J4は夫々独立にN又はCR6;R1及びR3は夫々独立にH、ハロゲン原子等;R2は-R7等;Xは夫々独立に-R7、-OR7等;R4及びR5は夫々独立にH、-R7等;R6はH、ハロゲン原子等;R7は1以上のハロゲン原子で置換/非置換のC1-C6鎖式炭化水素基;R9及びR10は夫々独立にH等]群(a):殺虫活性成分、殺ダニ活性成分及び殺線虫活性成分からなる群、群(b):殺菌活性成分、群(c):薬害軽減成分、群(d):植物成長調整成分【選択図】なし
