Influence of various parts of sweet corn ears on pesticide residue levels
Pesticide residue levels in various parts of sweet corn ears were analyzed. For this purpose, five pesticides were sprayed on corn in two different fields, and the harvested samples were separated into four portions, namely kernels, cobs, silks, and husks. Each of these portions was then separately...

| description | Pesticide residue levels in various parts of sweet corn ears were analyzed. For this purpose, five pesticides were sprayed on corn in two different fields, and the harvested samples were separated into four portions, namely kernels, cobs, silks, and husks. Each of these portions was then separately analyzed. Pesticide residues were predominantly distributed in the silk and husk portions, which constituted ≥91% of the whole crop, whereas relatively minimal residues remained in the kernel and cob portions. Further, residue distributions in the silks and husks were found to differ between the two fields. The calculated residue levels in kernels with the cob and silk were obviously higher than the residue levels in the kernel alone (max. >62 times different). This result suggests that the silk portion could greatly affect pesticide residue levels in the edible portion of corn. |
