Diseases of aloevera :-<\/p>\n
Aloe Rust :-
\nPhakopsora pachyfhiza and P. meibomiae <\/p>\n
Symptoms :-
\n\u2219 Aloe rust is a fungal infection that invades leaf structure and forms hard, blackened spots. \u2219 The good news is that this condition does not kill the plant, and new growth will not show signs of the rust. Most aloes lose their leaves as they grow. When they fall off, throw them in the trash.
\n\u2219 Many plant species can serve as hosts for these fungi. Some have built up immunity, while the aloes, haworthias and gasterias have not. The spores of the fungi are carried by the wind and can travel a long distance. The conditions that favor infection are extended periods of leaf wetness and a temperature range of 60 to 82 degrees F. Temperatures above 86 degrees prevent development of the disease.
\n\u2219 Spores are produced 10 days after infection and released about three weeks after that. As long as the environment is moist with moderate temperatures, spores will be generated.
\n\u2219 There are some ways to prevent aloe rust from occurring. First is to not let water stay on the leaves. Good air circulation can help keep leaves dry. Get rid of any leaves that you have cut off or have fallen off as soon as possible.
\n\u2219 Dust plants with sulfur powder every one to two weeks. This will not kill the rust, but will prevent germination of new spores. Spray a solution of one teaspoon of baking soda in one quart of water to help fight the rust. Foliar fungicides may also help. In one article, the author recommended using copper oxychloride.
\n\u2219 Small, pale yellow spots on leaves which expand and turn brown; orange spore masses may be present on underside of leaf; leaves may drop from plant. <\/p>\n
Management :-
\nDisease is self limiting and requires no treatment. <\/p>\n
Anthracnose : Colletotrichum gloeosporiodes
\nSymptoms :-
\n\u2219 The initial appearance of small round to oval
\n\u2219 dark green water-soaked which later become circular spots with tan to light brown center.
\n\u2219 As the spots mature the center of the lesion become reddish brown to brown color. \u2219 With progress in disease the lesions join together to form big necrotic area.
\nManagement :-
\nApplication of suitable fungicides.<\/p>\n
Bacterial soft rot : Pectobacterium chrysanthemi
\nSymptoms :-
\n\u2219 Watery,
\n\u2219 rotting leaves which are darker in color;
\n\u2219 young leaves wilting and collapsing;
\n\u2219 leaves bulging due to gas formation inside.<\/p>\n
Management :-
\nFatal disease; avoid over-watering plants. <\/p>\n
Sooty Mold :<\/p>\n
\u2219 Symptoms :-
\n\u2219 Sooty mold is a fungal infection that is secondary to an infestation of aphids or mealy bugs.
\n\u2219 Aphids and mealy bugs are pests that suck moisture out of plants, and leave a clear, sticky substance called honeydew behind on the leaves.
\n\u2219 The honeydew creates a moist atmosphere, which eventually develops into sooty mold.
\n\u2219 Sooty mold is a fungal infection that is secondary to an infestation of aphids or mealy bugs.
\n\u2219 Aphids and mealy bugs are pests that suck moisture out of plants and leave a clear, sticky substance called honeydew behind on the leaves.
\n\u2219 The honeydew creates a moist atmosphere that eventually develops into sooty mold. Sooty mold does not kill the plants; the insects will do that.
\n\u2219 To address sooty mold, wash off the honeydew. This substance can be hard and lessen the amount of light reaching the leaves, reducing photosynthesis. <\/p>\n
Basal Stem Rot :-<\/p>\n
\u2219 Symptoms :-
\n\u2219 Basal stem rot is the result of cold or wet conditions.
\n\u2219 This condition leads to rotting stems. The base of the plant is usually affected. Rotted aloe tissues affected by basal stem rot turn black or reddish brown.
\n\u2219 It is possible to take a stem cutting above the rotten portion to save pieces of the plant.
\n\u2219 Now that the critters are out of the way, we turn our attention to diseases. The first and most familiar disease is basal stem rot.
\n\u2219 The result of cold and wet conditions, this condition leads to rotting stems. Aloe tissues affected by basal stem rot turn black or reddish brown.
\n\u2219 It is possible to take a stem cutting above the rotten portion to save pieces of the plant. (As you can see in the picture), this plant is a goner. The rot travels up the stem, so early detection is a must.
\n\u2219 Base of plant turning reddish brown to black and rotting. <\/p>\n
Management :-
\nPieces of plant may be saved by taking cuttings above rotted portion. <\/p>\n
Fungus Gnats <\/p>\n
Symptoms :-
\n\u2219 One last pest that may affect your aloes is fungus gnats. Fungus gnats are generally the result of overly wet soil.
\n\u2219 Allowing the soil to dry out will kill the gnats and prevent them from spreading. Fungus gnats are easy to prevent altogether by not overwatering.
\n\u2219 If overwatering is an issue, you may be inviting disease. <\/p>\n
Management :-
\n\u2219 These diseases can be prevented by taking a few precautions.
\n\u2219 Water infrequently and only in the early morning to allow excess water to drain and evaporate.
\n\u2219 Water the soil and avoid watering from overhead.
\n\u2219 Aloes are planted in areas where they receive air circulation and at least 10 hours of sunlight per day.
\n\u2219 Fungal diseases that affect aloe plants are treated with spray of fungicides. If the disease is caught early, the plant is usually saved.
\n\u2219 If the plant succumbs to disease, treat the soil with fungicides to prevent future plants from becoming diseased.<\/p>\n","protected":false},"excerpt":{"rendered":"
