Will 24d kill trees

Yes, 2,4-D (2,4-dichlorophenoxyacetic acid) can kill trees if applied improperly or at high concentrations. It is a systemic herbicide that targets broadleaf plants, and while it's primarily used for controlling weeds, it can harm desirable trees if they absorb the chemical. To prevent damage, it's essential to follow label instructions carefully and avoid applying it near tree roots or during times of active growth.
