Phytophthora citrophthora, also known as brown rot of citrus, is a soil borne oomycete that infects several economically important citrus crops. [1] A diagnostic symptom of P. citrophthora is gummosis, wherein lesions around the base of the tree exude sap. [2] Other common symptoms include dark longitudinal lesions forming at the soil line, a ...
Alternaria stem-end rot Alternaria citri: Anthracnose = wither-tip Glomerella cingulata Colletotrichum gloeosporioides [anamorph] Areolate leaf spot Thanatephorus cucumeris = Pellicularia filamentosa Rhizoctonia solani [anamorph] Black mold rot Aspergillus niger: Black root rot Thielaviopsis basicola Chalara elegans [synanamorph] Black rot ...
Host and symptoms. Alternaria citri is an ascomycete fungal plant pathogen that causes black rot in citrus plants. [1] Specifically, certain lemon, lime, orange, mandarin and grapefruit species are susceptible hosts for this pathogen. [2] [3] The host is more susceptible to disease in climates with dry, warm summers and cool, moist winters.
Penicillium digitatum (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm ˌ d ɪ dʒ ɪ ˈ t eɪ t əm /) is a mesophilic fungus found in the soil of citrus-producing areas.

Brown rot on apple. Fruit rot appears as small, circular brown spots that increase rapidly in size causing the entire fruit to rot. Greyish spores appear in tufts on rotted areas. [4] Infected fruit eventually turn into shrivelled, black mummies that may drop or remain attached to the tree through the winter.
Botrytis cinerea. Botrytis cinerea is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes.
Peronosporaceae. Genus: Phytophthora. Species: P. boehmeriae. Binomial name. Phytophthora boehmeriae. Sawada, 1927. Phytophthora boehmeriae is an oomycete plant pathogen that causes disease on a wide range of host plants, including root rot of Mexican yellow pine and brown rot of Citrus fruits.
Citrus canker is a disease affecting Citrus species caused by the bacterium Xanthomonas (X.axonopodis; X. campestris). Infection causes lesions on the leaves, stems, and fruit of citrus trees, including lime, oranges, and grapefruit. While not harmful to humans, canker significantly affects the vitality of citrus trees, causing leaves and fruit ...
