Abstract

Crop field trials were conducted to investigate the residues of sprayed pesticides on the different sizes of tomatoes. Pesticide residue data in tomatoes varied due to different locations of the three crop fields selected and/or physicochemical properties of the three pesticides tested. The pesticide residue levels in the medium- and small-sized tomatoes were 1.5 and 2.4 times higher than the level in large-sized tomatoes under similar spray conditions, whereas amount of pesticides adhered per unit surface area were approximately equal among all three sizes of tomatoes. The results of this study suggested that the differences in pesticide residue levels were due to differences in the degree of specific surface area of each tomato size. Resultant residue data of medium-sized tomatoes demonstrated a proportional relationship between pesticide residue levels and the specific surface area of tomatoes.

小、中、大番茄农药残留附着趋势比较。
通过田间试验研究了不同大小番茄的农药残留量。番茄中的农药残留数据因所选三种作物的不同位置和/或所测三种农药的理化性质而有所不同。在相同喷雾条件下,中、小型番茄的农药残留量分别是大型番茄的1.5倍和2.4倍,而三种大小番茄单位表面积的农药残留量基本相等。本研究结果表明,农药残留水平的差异是由于每个番茄大小的比表面积大小的差异。中等大小番茄的残留数据表明,农药残留水平与番茄比表面积成正比关系。
