Late blight is a potentially destructive disease of tomatoes (and potatoes) caused by the fungal-like organism, Phytophthora infestans. This pathogen is referred to as a ‘water mold’ since it thrives under wet conditions. All tomato plantparts can become infected by late blight, with leaf lesions beginning as pale green or olive green areas that quickly enlarge to become brown-black, water-soaked, and oily in appearance (Figure 1).
