Pests inadvertently added to treated soil have no competition and may cause more damage than they normally could in untreated soil. Disinfest all tools, flats, and equipment which will be used to handle the treated soil. Do not walk or drive on treated soil. The following is a summary of information taken from product labels, state bulletins, and the scientific literature. Other methyl bromide sensitive crops include celery, onion, cauliflower, salvia, garlic, delphinium, carnation, snapdragon, and lettuce.
Most fumigants temporarily raise the level of ammonia and soluble salts in the treated soil.
Proper aeration and, sometimes, leaching will restore the proper balance of elements.
