摘　　要：报导了光活化农药δ－氨基乙酰丙酸（简称δ－ＡＬＡ）除草增效剂的研究。研究筛选出了效果显著的增效剂，讨论了其增效作用机理。表明其增效作用是与植物体内Ｆｅ￣（２＋）密切相关。增效剂的存在，抑制了叶绿素合成酶的作用，加速了植物体内δ－氨基乙酰丙酸的合成。Studies have been carried out on the synergist of the photoactivation pesticide δ-aminolevulinic acid(δ-ALA for short).1 ,10-phenanthroline and 2.2'-bipyridine is selected as the synergist.The enhancement mech-anism is discussed.It has been shown that the enhancement depends on the iron ion (Fe￣(2+))in plant directly.The synergist causes the activation of the enzyme which synthesize δ-aminolevulinic acid and inhibition ofchlorophyl synthesis in a number of organisms.
