Basil downy mildew has been confirmed in field-grown basil in southern New Jersey. This is the first confirmed report of BDM in the state this growing season. To date, there have been very few reports of BDM in the mid-Atlantic and Northeast regions this growing season. The extremely hot, dry weather these past three to four weeks have not been ideal for its development. However, all basil growers are encouraged to scout their fields or greenhouses on a daily basis and should consider initiating a preventative fungicide program.
