Late blight has been confirmed in several locations in Ontario recently. See the post from ONVegetables for more information.

While late blight is predominantly a problem on potato and tomato, specialty vegetable growers should be aware that tomatillo is also a potential host of this disease. Eggplant is not commonly been observed to be affected by late blight, however it is listed as being “occasionally mildly affected” by the disease. Specialty eggplant and tomatillo growers should be checking their crops for signs of this disease.

Note that not all fungicides registered on tomato can also be used on tomatillo. Always check product labels before applying to confirm that tomatillo is listed.
