The influence of formulation properties on spray droplet spectra and soil residues was studied in conifer forests in New Brunswick following aerial application of two oil-based aminocarb formulations of variable viscosities and volatilities. For a given volume rate of application, the formulation of low viscosity and high volatility provided a spectrum of small droplets and a low volume deposit on ground cards. For the same volume rate, the nonvolatile formulation of high viscosity provided a spectrum of larger droplets and consequently a higher volume deposit. Both formulations provided low soil residues, although those obtained with the nonvolatile formulation were much higher and persisted for much longer periods than those obtained with the volatile formulation. However, with both formulations the soil residues decayed to undetectable levels (less than 3 ng/g) within 5 days after spraying, indicating that none of the formulations caused any undue persistence of aminocarb in forest soils.
在新不伦瑞克省的针叶林中，在对两种粘度和挥发性不同的油基氨基甲酸酯制剂进行空中喷洒后，研究了制剂特性对喷雾液滴谱和土壤残留的影响。对于给定的施用量，低粘度和高挥发性的制剂产生了小液滴谱，并且在地面卡片上的沉积量较低。对于相同的施用量，高粘度的非挥发性制剂产生了较大液滴谱，因此沉积量较高。两种制剂的土壤残留量都较低，尽管非挥发性制剂的残留量比挥发性制剂高得多，并且持续时间长得多。然而，两种制剂的土壤残留在喷洒后5天内都衰减到检测不到的水平（低于3纳克/克），这表明没有一种制剂会导致氨基甲酸酯在森林土壤中过度残留。
