There are methods to treat powdery mildew using home-made preparations including fresh milk, which contains the active anti-pathogenic compound lecithin. [9] Lecithin is recognized by the European Union as a treatment for powdery mildews diseases and is commonly available in the soy-derived formulation ‘soy lecithin’. [ 10 ]
Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella.As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [2] all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
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 infectious dose is 1000–10,000 bacteria (although ten to five hundred bacteria can be enough to infect humans). Campylobacter species are sensitive to hydrochloric acid in the stomach, and acid reduction treatment can reduce the amount of inoculum needed to cause disease. [citation needed]
Management of bacterial leaf blight is most commonly done by planting disease resistant rice plants. PSB Rc82 is the standard variety of rice used in Southeast Asia, and the use of this cultivar enables the harvest of an estimated 0.8 million metric tons of rice per cropping season that would have otherwise been lost to bacterial leaf blight.
