RESIDUE SYMPTOMS ON MATURE PLANTS
Injury symptoms should be detected before maturity, as these symptoms also mimic those caused by herbicide drift. Severe injury symptoms are long lasting and significantly affect plant development. Signifi cant meristem damage effectively prunes plants and they respond with either production of damaged leaves and weak side shoots, or no growth at all.
| Severe early injury caused disruption of the meristem(red arrow) and increased production of immature side shoots (yellow arrow). |  |
| Symptoms observed at this stage are: 1) significant disruption of the meristem (yellow arrow) as well as production of immature and numerous side branches (white arrow), and |
 |
| 2) abortion of inflorescences (red arrow). |  |
