How long does 2,4-D stay in the ground?
The half-life of 2,4-D in the environment is relatively short, averaging 10 days in soils and less than ten days in water, but can be significantly longer in cold, dry soils, or where the appropriate microbial community is not present to facilitate degradation.
Can you spray 2,4-D at night?
