The volume of flame, however, is increased by inert gas, and there is a proportionate diminution of the heating effect. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various.

Plants that have been damaged are particularly susceptible to being infected by tomato early blight alternaria. When a plant is infected with Alternaria Alternata, it will normally appear first on the lower leaves of the plant in the form of plant leaf spots that are either brown or black. These tomato leaf spots will eventually migrate to the stem and even the fruit of the tomato.
Do not can tomatoes with late blight. Tomatoes showing signs of late blight disease have firm, dark brown lesions that quickly become large, wrinkled and somewhat sunken. Diseases such as this may lower the acidity of the tomato flesh to a level that makes it unsafe for canning.ate blight in both tomatoes and potatoes is caused by the oomycete Phytophthora infestans, and is a worldwide destructive disease. Under favorable weather conditions, tomato and potato crops can be destroyed within days.
