Ethel Doidge
Ethel Mary Doidge (1887–1965) was a British born, South African mycologist and bacteriologist. __NOTOC__ Doidge was born in Nottingham, England on 31 May 1887 and was educated in South Africa at Epworth School in Pietermaritzburg and Huguenot College, Wellington, Western Cape. In 1908 she joined the Transvaal Province, Transvaal Department of Agriculture as an assistant to Illtyd Buller Pole-Evans, Dr I.B. Pole Evans. In 1909 she was awarded a M.A. degree by the University of the Cape of Good Hope, and in 1914 she was awarded a D. Sc. degree; she was the first woman to obtain a doctorate in South Africa. Her thesis was entitled ''A bacterial disease of mango, Bacillus mangiferae n. sp.''. This disease was previously unknown outside South Africa and caused considerable loss to mango growers there for some years. In 1912 she was elected a Linnean Society of London, Fellow of the Linnean Society (F.L.S). She was appointed assistant chief of the Division of Botany and Plant Patholog ...

Fungal Plant Pathogens And Diseases
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avocado Tree Diseases
The avocado (''Persea americana'') is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated by Mesoamerican tribes more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large berry containing a single large seed. Avocado trees are partially self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year. The fruit of domestic varieties have smooth, buttery, golden-green flesh when ripe. Depending on the cultivar, avocados have green, brown, pu ...
