Golden fiber jute, natural fiber. The rural economy of Bangladesh depends on jute. At the same time, cotton was our main source of foreign exchange. Jute cultivation should be started before monsoon. At this time, it becomes somewhat impossible to grow another crop on the low land.
Many Diseases of Jute & it solution are below:
Jute Leaf Mosaic Virus (Chlorosis), a viral disease
Yellow-green spots appear on the leaves. The affected tree is shorter. The disease is transmitted by the white fly insect. Integrated suppression management: Collect seeds from disease-free trees. If you see an infected person, just pick it up and destroy it. Suppressing white flies, such as Sabikran- 2 ml or Tido or Edmair- 0.5 ml, Emitaf- 0.25 ml/liter of water and spraying.
Foot Rot or Soft Rot of Jute (Sclerotium rolfsii), fungal disease
In those native jute fields where the water cannot be drained, a kind of fungus like white cotton scales grows overnight at the base of the jute plants in those fields. After a few days, brown germs like mustard seeds appear. As a result of this disease, the root of the tree rots and the tree falls. The outbreak of this disease occurs from June to October. If this disease occurs in the land, the tree should be cut and collected. Outbreaks of this disease can be seen in both desi and tosha leaves. Integrated suppression management: After jute cutting, the base, roots and other parts of the tree should be collected and burned. Do not keep the field around the field unclean In order to cure this disease, the land should be kept clean and free from human habitation. Appropriate arrangement of water drainage should be made. The seeds should be cleaned before sowing. The use of Vitavex 200 (0.4%)/Provex-200 (0.4%) for seed treatment gives considerable benefits. The main fungal diseases of jute are seed and soil borne. As a result of seed treatment before sowing, the incidence of disease is greatly reduced. If cleaning is not possible, the seeds should be dried well in the sun before sowing. Dithen M-45 mixed with 20 grams per 10 liters of water and applied to the base of the tree for two consecutive days reduces the severity of the disease.
Anthracnose of jute (Colletotrichum corchori), fungal disease
There is a black spot on the stem. Gradually, this scar spreads and the affected area bursts. Sometimes the scales of the affected area come out like a rash. After rotting the affected area is hard. The fiber of the affected tree is of poor quality. Integrated suppression management: Remove the affected tree and burn it. After harvesting jute, collect and burn other parts of the crop. Collect seeds from healthy and disease-free trees. Use balanced chemical fertilizers. Seed treatment – 2 g Bavistin or Vitavex 2.5 g/kg seed. If the attack is more, spray by mixing Bavistin-1 gram, Acrobat-2 gram, Tilt 0.5 ml or Kupravit-4 gram per liter of water.
Wilting of jute (Rhizoctonia solani), fungal disease
Under the attack of this disease, the whole tree gradually falls down. A brown spot falls on the base of the tree. Tosha Pat often dies from this disease when it flowers. This disease is rarely seen in domestic jute. Integrated suppression management: If you see an infected person, pick it up and burn it. Do not allow water to accumulate on the ground. Collect seeds from disease-free trees. Use fertilizer in moderation. (especially potash fertilizer). Seed treatment before sowing, Vitaflo or Provex or Vitatex – 3 g or Bavistin – 2 g/kg seed. If the attack is high, spray by mixing Cupravit 4 grams or Dithen M-45 at the rate of 2.5 grams per liter of water.
Stem Rot of Jute (Macrophomina phaseolina), fungal disease
In the seedling state, a dark brown spot appears on the stem. The stain gradually spreads. The stem is weak. The tree fell from the affected area. Sometimes the tree dies from stem rot. During germination, the fungus attacks the seeds and the plant dies before it reaches the ground. Integrated suppression management: If you see an infected person, pick it up and burn it. Collection of seeds from healthy and disease-free trees. Use fertilizer in moderation. Seed treatment before sowing, Vitaflo or Provex or Vitatex – 3 g or Bavistin – 2 g/kg seed. If the attack is more, spray Dithen M-45 by mixing 2.5 grams per liter of water.
Black Band of Jute (Botryodiplodia theobromae), fungal disease
A black ring is formed on the stem of jute. If you rub the affected area with your hand, a black spot will stick to it. At the end of the season, the incidence of the disease is higher. Integrated suppression management: As soon as you see the affected tree, pick it up and burn it. Collect seeds from healthy, strong and disease-free trees. Seed treatment before sowing, Vitaflo or Provex or Vitatex – 3 g or Bavistin – 2 g/kg seed. Arrangement of water drainage on the land. If the attack is more, spray Dithen M-45 by mixing 2.5 grams per liter of water.
