I spayed my lawn with 2-4-D on a calm evening at the rate according to the label. I chose the evening as to not have issues with temperature inversion. There was no droplet or liquid drift onto my garden. There was a chemical odor after spraying. Two days later i notice my green beans and cucumber leaves were wilting but perked up two days later and now appear normal, it has now been 7 days since the lawn was spayed. It looks like the first picking of beans will be ready in another 7 days will they be safe to eat? Sorry i did not think to take any pictures.
