Moth bean Crop Stage Wise IPM

Management

Activity

Pre-sowing

 

Common cultural practices:

  • Timely sowing should be done.
  • Field sanitation.
  • Destroy the alternate host plants
  • Plant tall border crops like pearl millet, sorghum for the management of aphids and whitefly.
  • Adopt ecological engineering by growing the recommended attractant, repellent, and trap crops around the field bunds.

Nutrients

  • Get the soil sample tested and apply nutrients based on soil test report. Soil is brought to fine tilth by 2-3 ploughing with harrow or plough.
  • Incorporate 4 to 5 tonnes of Farm Yard Manure per acre in soil 2-3 weeks before sowing.

Weeds

  • Solarisation of soil during summer reduces weed infestation.

Sowing

 

Common cultural practices:

  • Timely and line sowing should be done
  • Use healthy, certified and weed free seeds.
  • Sow with proper spacing

Nutrients

  • Fertilizers should be applied on soil test basis

Weeds

  • Always use certified and weed free seeds.
  • Timely sowing should be done.
  • Line sowing should be done to facilitate inter-culture operations.
  • Plant population should be maintained to its optimum right from its beginning to minimize the crop weed competition

Vegetative stage

 

Common cultural practices:

  • Collect and destroy diseased and insect infested plant parts.
  • Provide irrigation at critical stages of the crop
  • Avoid water stress and water stagnation conditions.

Common mechanical practices:

  • Collection and destruction of eggs, early stage larvae and adult beetles of white grub.
  • Use yellow sticky traps for aphids and whitefly.
  • Use light trap @ 1/acre and operate between 6 pm and 10 pm

Common biological practices:

  • Conserve natural enemies through ecological engineering
  • Augmentative release of natural enemies

Nutrients

  • Correct micronutrient deficiency if any in standing crop.
  • Seed treatment of Thiourea @ 500 ppm in light soils.
  • Foliar application of Thiourea @500ppm solution twice in standing crops

Weeds

  • Keep field boundary & bunds free from weeds.
  • The crop field should be weed free initially for 3-4 weeks.
  • Inter-culture operation/hoeing should be done twice at 20 and 35 days after sowing-using hand hoe to remove all weeds in between the row.
  • Mulches like straw, hay, plastic, etc. should be used in between the rows to suppress the weed growth

Aphids

  • Follow common cultural, mechanical and biological practices.

Cultural control:

  • Apply optimum doses of nitrogen fertilizers
  • Regular field monitoring in the morning hours for monitoring of pests and defender population, barrier crops like pearl millet and sorghum around the field.

Biological control:

  • Conserve predators such as ladybird beetles (Cocciniella septumpunctata, Menochilus sexmaculata and Brumoides suturalis.

Root grub

  • Follow common cultural, mechanical and biological practices

Biological control:

  • Use Entomopathogenic nematodes

Whitefly

  • Follow common cultural, mechanical and biological practices

Biological control:

  • Spray neem seed kernel extract (NSKE) 5%.
  • Spray neem oil @ 1%

Spotted pod borer

  • Follow common cultural, mechanical and biological practices.

Cultural control:

  • Inter cropping are found to be effective.
  • Collect and destroy the larvae.
  • Keep the field weed free in the initial 25-40 days through intercultural operations and hand weeding

Pod bugs

  • Follow common cultural, mechanical and biological practices

Biological control:

  • Aggregation pheromone traps are widely used as a monitoring tool and partial control measure

Fusarium wilt

  • Follow common cultural, mechanical and biological practices

Mung bean Yellow mosaic virus

  • Follow common mechanical and biological practices

Cultural practices:

  • All the infected plants should be removed carefully and destroyed.
  • Control the whitefly

Bacterial leaf spot/blight

Follow common mechanical and biological practices

Cultural control:

  • Use disease free and certified seeds.

Charcoal rot or ashy stem blight

  • Follow common mechanical and biological practices

Cultural control:

  • All the infected plants should be removed carefully and destroyed.
  • Follow intercropping cropping system (Mothbean: Sesame) (1:1 ratio).
  • Irrigate field every two weeks to avoid stress contitions

Reproductive stage

Nutrients

  • Incorporate crop residues in soil immediately after harvest

Weeds

  • Remove left over weeds to prevent weed seed spread in field.

Pod bugs

  • Follow common cultural, mechanical and biological practices

Biological control:

  • Aggregation pheromone traps are widely used as a monitoring tool and partial control measure.

Spotted pod borer

  • Same as in vegetative stage
