PROBLEM TO BE SOLVED: To provide a seed coating agent attaining coating that causes only a small amount of iron powder fall off not only during a sowing process but also during a transportation process, and to provide seeds coated with the seed coating agent.SOLUTION: The seed coating agent used for coating the surfaces of seeds contains iron powder and a binding material. The iron powder, the percentage by mass of iron powder particles having a particle size smaller than or equal to 63 &mum to the total mass of the iron powder is from 0 to 75% inclusive, the percentage by mass of iron powder particles having a particle size larger than 63 &mum and smaller than or equal to 150 &mum to the total mass of the iron powder is from 25 to 100% inclusive, and the percentage by mass of iron powder particles having a particle size larger than 150 &mum to the total mass of the iron powder is from 0 to 50% inclusive. The average particle size of the binding material is between 1 and 150 &mum.COPYRIGHT: (C)2012,JPO&INPIT【課題】播種工程のみならず輸送工程においても鉄粉の脱落が少ない被覆が実現できる種子被覆剤及び該種子被覆剤で被覆した種子を得る。【解決手段】本発明に係る種子被覆剤は、種子表面を被覆するのに用いる鉄粉と結合材を含む種子被覆剤であって、前記鉄粉は、粒子径が63μm以下の鉄粉の全鉄粉質量に対する質量比率が0%以上75%以下、かつ、粒子径が63μmを越え150μm以下の鉄粉の全鉄粉質量に対する質量比率が25%以上100%以下、かつ粒子径が150μmを越える鉄粉の全鉄粉質量に対する質量比率が0%以上50%以下であり、前記結合材は、その平均粒径が1~150μmであることを特徴とするものである。【選択図】 図1
