研究了甲霜灵在几种作物上的吸收、传导以及残留消解动态。豌豆根吸收的甲霜灵主要传导到茎与叶中,并在叶缘表现出积累效应,而涂叶法引入的甲霜灵则主要存留于引入叶中,向外传导的很少。白菜和油菜施药3周后残留浓度均低于0.5mg·kg-1。春小麦花期和灌浆期引入的甲霜灵,在收获时主要残留于麦秆中,其残留量可分别占到引入量的42.6%和55.4%,籽粒中的总残留浓度分别为0.35mg·kg-1和0.56mg·kg1,其中一半以上为结合残留。平菇中甲醇提取残留为0.11mg·kg-1,结合残留为0.0147mg·kg-1.一个采收期后,引入量的97%残留于基料中。
Metalaxyl was studied in several crops on the absorption, conduction and residual digestion dynamics. Metalaxyl absorbed by the pea roots is mainly transmitted to the stems and leaves and shows a cumulative effect at the leaf margin, whereas metalaxyl introduced by the spreading method mainly remains in the introduced leaves with little outward conduction. The residual concentrations of cabbage and rape were lower than 0.5 mg · kg-1 after 3 weeks. Metalaxyl introduced at the flowering and filling stages of spring wheat mainly remained in the straw during harvesting, and the residues were 42.6% and 55.4% of the introduced amount respectively, and the total residual concentrations in the grains were 0 .35mg · kg-1 and 0.56mg · kg1, of which more than half were binding residues. Pleurotus ostreatus methanol extraction residue was 0.11mg · kg-1, with a combined residue of 0.0147mg · kg-1. After a harvest period, 97% of the amount introduced remains in the binder.
