This question recently arrived in our email inbox; Arlene wrote:
My husband sprayed our lawn with Spectricide. The overspray damaged parts of our garden plants (tomato and grapes) and they became frail with curled leaves. My question is: If we plant new plants around these weakened, frail plants will they contaminate the new plants? We removed a couple of them and replaced with new plants, removing the soil around the root base and these plants show the same sign of weak, frail stems with curled leaves. Could this be possible that the weakened plants pass this on to other plants nearby? Thank you for your response.
