I write to add an additional resource to support late blight management in tomato for Wisconsin growers. Attached, please find a multi-page table which includes registered fungicides for management of late blight in tomato in Wisconsin. The list includes modes of action of each fungicide, re-entry intervals, and pre-harvest intervals along with other comments on use limits.
