Biotic and Abiotic stresses on Banana crop

 

 

Biotic Stress

 

Management

1)

Insect pests and diseases, Sigatoka.

 

Corm treatment, proper spacing, Recommended fungicides and Sanchar- 40 application through drenching and spraying.Integrated management of pests and diseases, biological pest management.

 

2)

Nematodes

Neem cake use, Marigold planting,use of Pacelomyces beneficial fungi.

3)

Animals

Fencing and other measures.

4)

Weeds

Weed management, Mulching, use of fully decomposed manures.

 

 

 

 

 

 

 

Abiotic Stress

 

Management

1)

Morphological change

Balanced use of fertilizers, variety selection, planting of good saplings.

2)

Physiological change

Use of biofertilizers, Seaweed extract and Humic acid use.

3)

Biochemical changes

Use of good irrigation water, Integrated nutrient management, Use of growth regulators.

 

4)

Molecular change

Inspect and remove uncommon plants.

5)

Water stress, Saline water, Draught, Excess rains, Hail storm, floods, Cloud burst etc.

Micro irrigation, water management as per season, water conservation through bunding. Mycorrhiza and other bio fertilizer use,Agriplex- OA application.

6)

Temperature stress, soil and atmospheric temperature very low or very high and its impact on nutrient uptake, root growth and micro organisms growth etc.

Mulching, Water management, Use ofSulphur (Thiogreen), Use of bio fertilizers and Mycorrhiza(Rootanza). Burning of dry grass in night around fields, Irrigation in night hours.

7)

High speed wind, storm, cyclone.

Wind breaks around fields, support to plants.

8)

Excessive use of chemical fertilizers.

Use of fertilizer as per soil analysis reports, use of Bio fertilizers, Integrated nutrient management.

9)

Excessive use of pesticides.

Use of pesticides as per recommendations only. Use of organic, Bio pesticides and non chemical devices and technologies.

10)

Stress due to high salinity, excessive uptake of salt by plants.

Use of good irrigation water and fertilizers. Use of Agriplex OA, Use of Rootanza (Mycorrhiza).

11)

Raw and heavy metal containing manures use.

Use only well decomposed manures as per FPO guidelines.

 

Banana crop affected due to heavy rains / floods.
