Abstract
Effect of expired herbicide on seed germination and seedling development of Mango (Mangifera indica) was investigated using Pendimethalin herbicides that have expired for 7, 5 and 1 years respectively. Two concentrations 100 and 150ml/l of each of the expired herbicides were used as the treatment concentrations for the investigation. Mango germination was delayed in all the herbicide treatments but not in the control treatment. Germination rate was consistently higher in the control treatment than in all the herbicide treatments except the herbicide that expired in 2011.There were no herbicide injuries nor growth retardation on Mango seedlings except slight stem distortion and reduced leaf size at the early emergence stage.
