Hi my name is Christina, I am excited to learn how to edit and write articles on Wikipedia. I am currently a medical assistant and am focusing on expanding my career to nursing.

Stub Article:

Dragonfly 44 - This galaxy article needs a lot more editing and research added in, although it is started will. It is missing specific information such as pictures, citations and additional information about the particular galaxy.

Black Leaf - The plant disorder that deteriorates specific grapes. This would be interesting to learn about and expand the article as there is not much available. It requires additional references, updated information, and pictures as well as citations. I noticed the external link about photosynthesis is from 1998. There are many more current articles and information up to date that could be incorporated into this article.

Alexander (Son of Perseus) - Ancient greek persons of Rome, this article needs more information as there is very little. It is missing pictures, citation, reference and additional content to the article itself.

Black Leaf
Black Leaf is a physiological plant disorder that affects some grape varieties such as Concord. It is essentially a potassium deficiency that causes the leaves on a vine to turn purple and eventually black as chlorophyll is lost. For wine growers this lack of chlorophyll inhibits the vine's ability to transmit sugar to the grape, leaving the resulting grapes with a low brix count that may be less than ideal for wine making.

Causes
Black leaf, also known as black spot disease can be caused by different types of fungi and bacteria. Most common being Asterina, Asterinella, Diplotheca, Glomerella, Gnomonia, Schizothyrium, Placosphaeria, and Stigmea. Black leaf can affect many different plant species during wet, damp climate. It may appear as black spots on leaves, stems, and flowers.

Prevention and Treatment
Treating black leaf disease can be achieved in many ways. Some include removing each affected leaf of any yellow or black color. If the infection has spread throughout a larger area, it may be best to remove the affected limb of the plant to reduce further spread. As a last resort, fungicides may be used as treatment, using organic based fungicides if possible. There are a number of remedies used to prevent the spread of black leaf disease, including mixtures of baking soda, soap, vegetable oil, and water.

It is important to follow steps in order to prevent black leaf. Space plants at a distance when planting new crops in an area that will receive an adequate amount of sunlight. Trim each plant as needed starting from the bottom and working up to the top, making sure to dispose of any affected leaves and limbs of the plant so it cannot further spread by mixing within the soil. Be sure to keep the soil area clean of fallen leaves, as this disease thrives in cold, wet weather. When watering each plant, aim towards the base soil area to prevent adding moisture to the leaves.
