• Related縮小しゅくしょうNeutralTo shrink in size or scope, as in 「事業縮小」; the focus is something becoming smaller, not strength or appeal being sapped.
• Related低下ていかNeutralA drop in level, quality or ability, as in 「体力低下」; it is about degree falling, while 「減殺」 is about effects being cancelled out.
• Related下落げらくWrittenWritten word for prices, values or ratings falling, as on the market; it belongs to market and valuation talk, not to weakened effects.
• Related短縮たんしゅくNeutralTo shorten time, distance or text, as in 「時間短縮」; the change is in length, not in strength or value being diminished.

For plain decreases in quantity, use 「減る」 or 「減らす」. 「減殺」 is a written word for effects, interest or charm being weakened or cancelled out, as in 「効果が減殺される」 or 「興味を減殺する」. To dampen someone's drive, say 「削ぐ」; for the opposite, strengthening, use 「増強」.
