Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months.
Uncontrolled bacterial blight has been shown to cause yield losses up to 20%. [68] Symptoms include small, dry, and brittle yellowish-brown spots on the plant and stalks covered in bacterial ooze. [69] The primary treatment of bacterial blight is applications of copper before the crop is fully mature. [69]
Bacterial seedling blight of rice (Oryza sativa), caused by pathogen Burkholderia plantarii [4] Early blight of potato and tomato, caused by species of the ubiquitous fungal genus Alternaria; Leaf blight of the grasses e.g. Ascochyta species [5] and Alternaria triticina that causes blight in wheat [6]
The most common cause of bacterial leaf spots are by bacteria in the genera Pseudomonas and Xanthomonas. For example, Pseudomonas syringae pv. tabaci is known to cause angular leaf spots of cucumber, Pseudomonas syringae pv. phaseolicola to cause bean leaf spot and Xanthomonas campestris pv. phaseoli, angular leaf spot of cotton. [7]
The bacteria need a film of water to facilitate infection. The bacteria can also be transmitted from one plant to another when beetles feed on an infected plant and the bacteria becomes attached to the beetles mouthparts. [4] The bacteria Ralstonia solanacearum and related species cause bacterial wilt of bananas and plantains. [5]
A number of different fungi and fungi-like organisms cause the symptoms of damping off, including: Alternaria – a genus of fungi that can cause leaf spotting. [2] Botrytis cinerea – a fungus, also known as "grey mould". Symptoms caused by this often accompany other symptoms. [2] Fusarium – a genus of fungi. [1]
