Chickpea diseases and their control

Major Chickpea diseases are:-

1.Chickpea Alternaria blight: Alternaria alternata

chickpea alternaria blight

  • The disease occurs during the flowering stage of the crop.
  • Leaves are infected most.
  • Shedding of lower leaves generally occurs in the infected plant.
  • The lesions are seen on leaflets as water soaked, small, circular and purple in colour.
  • Infected pods turn blackish in colour.
  • Infected seeds get shrivelled.
  • The plants should be planted distantly.
  • Avoid excessive vegetative growth.
  • Intercrop with linseed.
  • Avoid excessive irrigation.
  • Use compact varieties.
  • Use Mancozeb at the rate of 2.5g/lit or Use Carbendazim at 1g/lit


2.Chickpea Ascochyta blight: Ascochyta rabiei

chicpea ascochyta blight

  • All plant parts are affected.
  • Symptoms appear on leaves as water soaked lesions.
  • Symptoms include smaller circular brown spots on leaves.
  • Under favourable conditions, these spots enlarge rapidly and coalesce, blighting the leaves and buds.
  • In the case of severe infection, the entire plant dries up suddenly.
  • The lesions are also developed on stems and petioles.
  • Late infections result in the shrivelled and infected seed.
  • The disease is seed-borne in nature.
  • Left over debris in the fields serve as a source.
  • Wet and warm weather and dense crop canopy are conducive to the spread of the disease
  • Sow disease-free seed.
  • Follow rotation crop.
  • Intercrop with wheat, barley, mustard
  • Seed treatment with Carbendazim @ 1g/kg of seed. or Hot water seed treatment (52 C for 10 min) to lower the infestation.
  • Spray the crop with Mancozeb @ 2.5g/lit if noticed during the growth period.
    or Spray Wettable sulphur at the rate of 2.3g/lit of water.


3.Botrytis gray mold: Botrytis cineria

chickpea gray mold

  • Lack of pod setting is the first indication.
  • Under favourable conditions, foliage shows symptoms and plants often die in patches.
  • Shedding of flowers and leaves, covered with spore mass can be seen.
  • Lesions on the stem are 10-30 mm long and girdle the stem fully.
  • Tender branches break off at the point where the gray mold has caused rotting.
  • Affected flowers turn into a rotting mass.
  • Lesions on the pod are water-soaked and irregular.
  • On infected plants, the pods contain either small, shrivelled seeds or no seeds at all.
  • Avoid excessive vegetative growth.
  • Intercrop with linseed.
  • Avoid excessive irrigation. Use compact varieties.
  • Deep summer ploughing Reduce plant density and increase in air passage between the plants.
  • Seed treatment with Carbendazim + Thiram (1:1) @ 3g/kg of seed is recommended or Spray the crop with Captan 5 – 6 kg/ha at 15 days interval./Spray of Carbendazim @ 1.5g/lit of water is recommended./Spray Mancozeb @3 g/lit of water.


4.Chickpea Collar rot: Sclerotium rolfsii

chickpea collar rot

  • It comes in the early stages i.e up to six weeks from sowing.
  • Drying plants whose foliage turns slightly yellow before death, scattered in the field is an indication of the disease.
  • Seedling becomes chlorotic.
  • The joint of stem & root turns soft slightly contracts and begins to decay.
  • Infected parts turn brown white.
  • Black dots, like mustard in shape known as sclerotia are seen appearing on the white infected plant parts
  • Deep ploughing in summer.
  • Avoid high moisture at the sowing time.
  • Seedlings should be protected from excessive moisture.
  • Destroy the residues of last crop and weed before sowing and after harvest.
  • All undecomposed matter should be removed from the field before land preparation.
  • Treat the seeds with a mixture of Carbendazim 1g per kg of seed.


5.Chickpea Dry root rot: Rhizoctonia bataticola/Macrophomina phaseolina

chickpea dry root rot
  • The disease appears from flowering to the podding stage as scattered dried plants.
  • The leaves and stem become straw coloured.
  • Affected plants wither and spread across the entire field.
  • The roots of infected plants become brittle and dry.
  • Deep ploughing in summer
  • Grow cultivars resistant to dry root rot.
  • Drought should be avoided.
  • Sowing should always be done on the recommended time.
  • Germinating and young seedlings should be saved from high temperatures.
  • Seed treatment with T. viride @4g/kg or P. fluorescens @ 10g/ kg of seed or Carbendazim or Thiram 2g/kg of seed.
  • Spot drenching with Carbendazim 1g/lit or P. fluorescens / T. viride 2.5 kg/ha with 50 kg FYM.


6.Chickpea wilt: Fusarium oxysporum f.sp.ciceri

chickpea wilt

  • The disease can affect the crop at any stage.
  • The field symptoms of wilt are dead seedlings or adult plants, usually in patches.
  • At seedling stage, 3-5 weeks after sowing, whole seedlings collapse and lie flat on the ground with dull green leaves and shrunken stem.
  • Dark brown or dark discoloration of the internal stem tissues is visible.
  • At adult stage, dropping of petioles, rachis and leaflets and finally, entire plant occurs.
  • Deep summer ploughing
  • Follow crop rotation measures continuously.
  • Always use disease free seeds.
  • Avoid sowing when temperatures are high.
  • Follow 6-year crop rotations with sorghum
  • Apply FYM 10-15 cart load/ha.
  • Seed treatment with T. viride @4g/kg or P. fluorescens @ 10g/ kg of seed or Carbendazim or Thiram 2g/kg of seed.
  • Spot drenching with Carbendazim 1g/lit or P. fluorescens / T. viride 2.5 kg/ha with 50 kg FYM.
  • Seed treatment with Carbendazim at the rate of 1g/kg of seed /
  • Seed treatment with Thiram + Carbandizm @ 1g+2g per kg of seed


7.Chickpea Powdery mildew: Oidiopsis taurica

chickpea powdery mildew

  • Crop plants of all the age group are affected.
  • With the onset of the disease white powdery mass appear on the leaves.
  • Small patches of white powder coating initially develop on both surfaces of older leaves.
  • Affected leaves turn purple and then die.
  • When infection is severe, stems, young leaves, and pods are also covered with the powdery coating
  • Field and crop sanitation.
  • Dithane M-45 or Carbendazim at 2.5 g/lit should be sprayed.
