落叶剂 一种植物生长调节物质，它能够促使植物的叶子提早脱落，有利于农业的机械化。例如，氰氨化钙的粉尘可使棉花的叶子提早脱落。 落叶剂可分为两大类：①无机落叶剂，包括氰氨化钙、氯酸镁、硫氰酸铵、硼酸盐、砷酸，以及它们的混合物。②有机落叶剂，是一些含有磷、硫和氮的化合物。S,S,S－三丁基三硫代磷酸酯PO(SC4H9)3是有机落叶剂的一个代表性产品，商品名为脱叶磷。脱叶磷是油状液体，配制成乳液使用。每平方米棉田用0.3～0.6克原药，施药6～12天,青叶就可以脱落干净。也可以用在苹果树上,但要在一个月前用药。S，S，S－三丁基三硫代亚磷酸酯P(SC4H9)3也是一种很好的落叶剂,商品名为脱叶亚磷。7－氧杂二环[2，2，1]庚烷－2，3－二羧酸二钠盐(见结构式a) 是棉花等作物的落叶剂。常用的有机落叶剂还有:O，O－二丁基二硫代磷酸钠盐(C4H9O)2P(S)SNa、二(乙氧黄原酰化)连三硫C2H5OC(S)SSS(S)COC2H5、二甲胂酸及其钠盐(CH3)2As(O)ONa、落叶酸（b）、六氯丙酮 CCl3C(O)CCl3和氨基三唑等。这些落叶剂除用于棉花和果树的采摘，还可用于土豆、啤酒花、亚麻、豆科作物和结籽作物等的收获。
