Also known as NIP (brand name). A diphenyl ether herbicide developed by the American company Rohm and Haas and introduced to Japan in 1956. It is a non-hormonal herbicide with no selectivity. When used in soil treatment, this herbicide is adsorbed to a relatively shallow part of the soil surface and does not migrate to deeper areas. Therefore, weeds growing on the soil surface are killed by contact, but crops with deep roots are not harmed. Taking advantage of this property, granules are often used as a herbicide for treating paddy field soil after rice transplanting, and emulsifiable concentrates and wettable powders are used as herbicides for field crops.

ニップ(商品名)ともいう。ジフェニルエーテル系の除草剤で,アメリカのローム・アンド・ハース社によって開発され,1956年に日本に紹介された。非ホルモン系の除草剤で,選択性はない。この薬剤は,土壌処理において土壌の表面の比較的浅い部分に吸着され,深部には移行しない性質を有する。したがって,土壌表面に生育する雑草は接触的に殺草されるが,深部に根を張っている作物は害を受けない。この性質を利用して,粒剤はイネ移植後の水田土壌処理除草剤として使用されることが多く,乳剤および水和剤は,畑作用除草剤として用いられた。
