Sugarcane diseases control

Sugarcane Red rot

Red rot is one of the major constraints in the profitable cultivation of sugarcane. This disease is destructive of sugarcane. These lesions later become dark brown with the light brown straw-colored center.  In later stages, stalks and hollowware are done. Black fruiting bodies develop on the peels and nodes. The diseased tissues emit the typical alcoholic odor. The juice of the affected stalks gives a sour alcoholic smell. In the very advanced stage of the diseases, the red color may be replaced by brown and white bands.

Management

i) As far as possible do not use the canes from the fields affected by the red rot diseases.

ii) Dip the setts in 0.20% solution of Agallol or Aretan for five minutes before planting.

iii) Long crop rotation should be followed.

iv) During the rainy season, the diseases spread fast. Bunding of the affected field may be done to avoid movement of the pathogen through the rain of floodwater.

Sugarcane Smut(sugarcane diseases and their control)

sugarcane smut

This is the common diseases of sugarcane cultivation. The sumt powder on this whip-like outgrowth is covered by a thin white, silvery membrane. The membrane soon ruptures and flakes off exposing dense black powdery dust of spores. For its life cycle, the fungus is systemic in the plant and produces no identifiable symptoms in the plant and produces no identifiable symptoms except for a grassy appearance in the severe case. The affected plants have usually slender and thin canes. The diseases are primarily transmitted through diseased cane setts.

Management

i) Use only smut free canes for planting.

ii) No ratoon should be kept in the diseased fields.

iii) Planting healthy pest and diseases free sets.

iv) Treat setts before with the solution of Agallol or Aretan (0.25%) for 5 minutes.

v) Use resistant variety.

vi) Crop rotation is the best.

Wilt (sugarcane diseases control)

The earliest symptom appears late in the season as yellowing and withering of crown leaves, followed by rapid drying of the cane. First symptoms of the diseases are visible in the canes of 4-5 month ago. The affected plants are yellowing and withering of crown leaves. Then all leaves in a crown generally turn yellow, while the leaf lamina may remain green and the leaves are dry up with stem develop hollowness in the core.

Management

i) All the infested canes leaves and roots should be completely burnt.

ii) No ratoon should be kept in the infested fields.

iii) Before planting use 0.25% solution of Agallol or Arean.

iv) Grow resistant varieties recommended for the particular area.

v) Grown mustard and coriander crop in the early stages of the crop.

vi)Burn trashes and stubbles in the field.

Grassy shoot (sugarcane diseases and their control)

Diseases symptoms are more conspicuous during the rainy season. This symptom appears in the young crop of 3-4 months age as thin papery white young leaves at the top the cane. The cane becomes stunted with reduced intermodal length with axillary bud sprouting.

Management

i) Grow resistant varieties.

ii) Hot air treatment of seed canes at 540 C for 24 hours inactivates the pathogen.

iii) Use seeds from the health fields.

iv) Do not use ration diseases plant.

Leaf Scald (sugarcane diseases and their control)

This is a Bacterial disease. Leaf Scald disease that can cause sugarcane death. It can heavy effect on sugarcane yields and potential to seriously limit the cultivation of susceptible varieties. Sometimes affected plants suddenly wilt and die without any obvious internal symptoms.

Management

i) Rogue out the diseased clumps.

ii) The diseases are sett-borne, healthy and diseases free seed should be planted.

iii) Use 2% Lysol solution during seed preparation should be practiced to minimize the spread of the diseases.

Red Striped (sugarcane diseases control)

This diseases should come to June-August. Long narrow dark red stripes develop on the leaves of young canes and rations. Young and middle leaves are most commonly affected.   The growing points of the shoot are yellow and later reddish with dark brown strips on the shoots.

Management

i) Collect good variety like Co410, Co527, Co 1158 and Bo17.sugarcane it is the best method of control.

ii) Do not select cane setts from diseases fields for planting.

Mosaic (sugarcane diseases and their control)

This symptom is more pronounced on the leaves newly unrolled from the spindle. The sheath may also display such symptom. These are irregular in shape and size, though usually oval or oblong with their long axis lying parallel to midrib. Mottling of the stem is the secondary symptom that becomes pronounced in some varieties.

Management

i) Select healthy setts for planting.

ii) Avoid jowar cultivation in close proximity of sugarcane.

iii) In the early years of this disease, attempts were made in Java and other countries to completely eradicate it by cutting and burning the diseased plants.

Rust (sugarcane diseases control)

sugarcane rust

The typical rust symptom develops as tiny elongated yellowish spots on both the surfaces of the leaves and leaf sheaths. The spots increase in size, become orange-brown to brown color.

Management

i) Follow the long furrow or pair row method of planting.

ii) Removal of affected and dried leaves.

iii) Grow resistant varieties.

iv) Spray Nickel Sulfate 0.5% or Ferbam 0.76% at 20-25 days after the appearance of the diseases.
