Important Pests of Sugarcane

1. Top shoot borer                              
2. Stem borer
3. Pyrilla                                                         
4. Mealy bugs
5. Grass hopper                                              
6. Termites
7. Woolly aphids                                
8. Field rats
9. White fly

1. Top Shoot Borer:

N.D:

1. The caterpillars enter the midribs of the leaves and bore downwards into the shoot from the top.
2. It results in drying of central shoot called as dead heart.

C. M:

1. Collection and destruction of egg masses.
2. Removal of affected plants along with caterpillar.
3. Apply 4 % endosulfan granules in leaf whorls or spray 0.05 % monocrotophos.
4. Release of egg parasite Trichogramma minutum @ 2.5 lakh/ha.

2. Stem Borer:

N. D:

1. The caterpillar initially feed on the leaves and later enters into the young shoot and tunnel downwards.
2. Thus central shoot dries up causing dead hurt which can be easily pulled out.

C. M:

1. Collection and destruction of egg masses.
2. Collection and destruction of dead heart along with caterpillar.
3. Give two light earthing ups during the early stage of crop growth.
4. Spray 0.05% endosulfan or monocrotophos.
5. Avoid rationing and plant healthy sets.
6. Release egg parasite Trichogramma minutum @ 2.5 lakh/ha.

3. Pyrilla:

N. D:

1. Straw coloured Nymphs and adults suck the cell sap from the lower surface of leaves which first wither and then dries up.
2. These insects excrete honey dew like substance on which black fungus develops and leaves turn black.

C. M:

1. Destroy all trash after harvesting.
2. Collect and destroy egg masses.
3. Spray 0.05 % endosulfan or 0.03 % monocrotophos or dimethoate two times at one week interval.
4. Release cocoons (pupaes) of parasite Epricania melanoleuca @ 5 lakh/ha.

4. Mealy Bugs:

N. D:

1. These insects (bugs) suck the sap near the nodes and leaf sheaths.

C. M:

1. Destroy infected sheaths.
2. Treat sets with 1 %. Fish oil rosin soap.
3. Spray 0.03% monocrotophos or dimethoate.

5. Woolly Aphid:

N. D:

1. The nymphs and adults having white woolly skin suck the cell sap from lower leaf surface because of sever incidence there is drying of leaves.
2. This results into reduction in yield and recovery of sugar.

N. D:

1. The nyphs and adults having white woolly skin suck the cell sap from lower leaf surface because of severe incidence there is drying of leaves.
2. This results into reduction in yield and recovery of sugar.

C. M:

1. Spray of dimethoate / endosulfan / methyl demeton @ 15 ml per 10 liter of water.
2. Dusting of methyl parathion (folidol dust) @ 40 kg/ha.
