How Long Do Systemic Sprays Last On A Plant ?
Somerset, United Kingdom
When i went to buy another fungicide yesterday one of the containers stated that the systemic action was effective for 14 days.
Is this normal for systemic sprays (of any kind) to only last this short period ?
I'd always presumed that systemic effects (of all kinds)were long lasting, have i been missing the point all these years ?
