Package of Practices for Chilli Cultivation

1. Introduction
Chilli is one of the most valuable spice crop. India is the largest producer consumer and exporter of Chilli cultivating in the area of 775 thousand hectares with 1492 metric tons production (2014-15 estimates) contributing about 40 % of the World’s chilli production. In India Andhra Pradesh is the leading state in Chilli production followed by Karnataka, West Bengal and Odisha.
Chilli belongs to the genus Capsicum under Solanaceae family. Five species of Capsicum are under cultivation, through number of wild species have been identified recently. In India, only two species viz. Capsicum annum and Capsicum frutescens are known and most of the cultivated varieties belong to the species Capsicum annum.

2. Climate and Soils
Chilli requires a warm and humid climate for its best growth and dry weather during the maturation of fruits. Chilli crop comes up well in tropical and sub-tropical regions, but it has a wide range of adaptability and can withstand heat and moderate cold to some extent. The crop can be grown over a wide range of altitudes from sea level upto nearly 2 100 meters. It is generally a cold weather crop, but can be grown throughout the year under irrigation. Black soils which retain mositure for long periods are suitable for rainfed crop whereas well drained chalka soils, deltaic soils and sandy loams are good under irrigated condition.

3. Land preparation
Chilli crop requires fine tilth which can be attained by ploughing 2-3 times. Stones and gravel are to be removed. In case of direct sowing, three to four ploughings are undertaken and sowing is done along with the last ploughing. The soil can be treated with azatobacter or azospirillum @ 11.25 kg mixed with 50 kg of farm yard manure and the same may be broadcast in the field. Farm Yard manure @ 46 t and 12 t of vermicompost can be added per acre.

4. Varieties – Characteristics

L.C.A-424, L.C.A-436, L.C.A-444 are results of these experiments.

5. Nursery bed preparation
Ideal nursery beds should be of 1m width, 40 m long and 15 cm height. Seedlings grown in this bed are enough to transplant in one acre main field. If there is more than one seed bed it’s better to make 30 cm width canals for drainage purpose.

6. Seed rate
For Nursery: 650 g seed is sufficient for transplanting in one acre.
Direct Sowing: 2.5 Kg to 3 Kg per acre

7. Sowing time
Kharif: July -August
Rabi: September- October

8. Seed Treatment
Seed treatment for viral disease prevention: To prevent seed borne viral diseases, seeds should be treated with Trisodium orthophosphate. Dissolve 150 g of Trisodium Orthophosphate in 1 litre water and soak 1 kg seed for 20 minutes in that solution. Remove the chemical water and wash the seed with fresh water for two times and keep the seed for drying under shadow.
Seed treatment for protecting from sucking pest: Treat 1 kg seed with 8 gm Imidacloprid
Seed treatment for protecting from seed borne diseases: For preventing seed borne diseases seeds should be treated with 3g Mancozeb or Capton per Kg seed.

9. Transplanting
Seedling of 6 weeks age are ideal for transplanting. Spacing for raifed crop should be 60 x 15 cm and for irrigated crop 60 x 60cm or 75 x 60 cm or 90 x 60cm.

10. Weed Control & Inter cultivation
One or two days before planting spray 1 litre Flucholoralin 45% per acre and plough the soil to mix properly or Spray 1.3 to 1.6 litres pendimethalin 30% or oxyfluorfen 23.5 % 200 ml by diluting in 200 litres of water before 1 or 2 days of planting. After 25-30 days of planting at frequent intervals of 15 -20 days based on necessity inter cultivation can be done by using cultivator or Indigenous blade harrow (Guntaka).

11. Fertilizers
10 tons of Farm Yard Manure per acre or grow and incorporate green manure crops.
For rainfed crop : Apply 60-40-50 Kgs Nitrogen, Phosphorus and Potash per hectare
For irrigated crop: Apply 300-60-120 Kgs Nitrogen, Phosphorus and Potash per hectare

Plant Protection
Insect agement

1. Thrips (Scirtothrips dorsalis) Causes: Upward curling of leaves
Found in almost all chilly growing areas. It is a polyphagus pest. Besides chilli, it also infests brinjal, cotton, groundnut, castor, bottlegourd, guava, tea and grapevine. It is more common on unirrigated chilli crop than irrigated one. They are s lender, tiny, straw coloured insects with fringed wings. A female adult inserts 40-48 white, minute eggs into veins. Both nymphs and adults lacerate the leaf tissues and suck the oozing sap, sometimes even the buds and flowers are attacked. Generally they attack tender leaves and growing shoots. Rarely the older leaves are attacked. Their damage results in

  • The infested leaves curling upward, crumbling and shedding
  • Infested buds turning brittle with petiole becoming brown and dropping down
  • Affected fruits showing light brown scars. Pest infestation is severe in dry weather. The damage ranges between 30-50%. One life cycle is completed on an average in 2- 2.5 weeks. There are about 25 generations in a year. Reproduction in thrips is generally sexual, parthenogenesis is also present.


  • Seed treatment with imidacloprid @ 3 -5 g/kg of seed.

2. Chilli Mites (Polyphagotarsonemus latus) Causes: Downward Curling of leaves
A minor pest emerged as a major pest in recent past. The infestation starts in the nursery after 40 days of germination. Severe infestation is seen in transplanted crop of 2-3 months old. The tiny white transparent mites are found in large numbers on the undersurface of leaves under fine webs. Both nymphs and adults suck sap and devitalize the plant causing ‘Murda’ disease of chillies. Infestation results in

  • Downward curling of leaves.
  • The affected leaves becoming inverted boat shaped.
  • The leaves rolling down along the margin with elongation of petioles.
  • Affected leaves turning dark green in certain cases.
  • Younger leaves at the tip of branch clustering.


  • Foliar spraying of dicofol 5ml/l or wettable sulphur 3g/l.
  • Synthetic pyrethroids not to be used.
  • If both thrips and mites are noticed, spraying phosalone 3ml/l or diafenthiuron 1.5 g /l or chlorfenapyr 2 ml/l.

3. Chilli Aphids (Aphis gossypii, Myzus persicae)
They are polyphagous pests. Cloudy weather is very favourable for multiplication of aphids. Heavy rains cause reduction in their population. Adults are found in large numbers on the under surface of leaves and growing shoots of plants. Both nymphs and adults suck sap and also excrete honeydew on which black sooty mould develops affecting photosynthetic activity thus it causing

  • Retardation in growth and fruiting capacity of the plant.
  • •Sooty mould

Foliar spray with methyl demeton 1 ml/l or acephate 1.5 g/l is effective.

4. Chilli Pod borers
( Spodoptera litura,S. exigua Helicoverpa armigera Utetheisa pulchella )
Feeding by S. litura, S. exigua leads to irregular holes on the leaves and fruits. Affected pods turn whitish and dry up. In fruits, seeds are also eaten. Attack of H.armigera leads to round hole on fruits. In addition to these borers, sometimes U. pulchella also feeds on the pericarp leaving the seed intact. Ladder like marks are seen on chilli pod due to U.pulchella . Their detailed history can be is given under pests of cotton and millets (S. exigua ).


  1. Deep summer ploughing.
  2. Monitoring with pheromone traps @ 4/acre
  3. Raising trap crops like castor (S. litura ), marigold (H.armigera).
  4. Spraying with SNPV/HaNPV at 250LE/acre in the evening.
  5. Spraying novuluron 1.0 ml/l or diflubenzuron 1.0 g/l controls just hatched larvae.
  6. Foliar spraying of thiodicarb 1.0 g/l or acephate 1.5 g/l or chlorpyriphos 2.5 ml/l or spinosad 0.3ml/l or quinalphos 2 ml/l.
  7. Poison baiting with rice bran 5 kg + chlorpyriphos 500 ml or carbaryl 500g + jaggery 500g with water in the form of small balls in the evening hours.

5. Root grub (Holotrichia consanguinea)
Damages plants by eating stem and roots. Initially survives on weed plants soon after planting chilli attacks plants which results in wilting and drying.


  • Application of well rotten Farm Yard Manure (FYM) will helps in prevention of root grubs
  • Application of Carbofuram 3% granules @ 33 Kg per hectare or 10 kg Phorate 10% granules per hectare

6. Chilli Blossom Midge (Asphondylia capsici)
Fly is dark reddish brown mosquito like midge that lays eggs in flower buds. Maggot is tiny pale orange colored and feeds on the floral parts leading to poor development of fruits. The ovary is distorted into gall like structure of varied shape.

Foliar spray with triazophos 2 ml/l or carbosulfan 2 ml/l followed by chlorpyriphos 2.0 ml/l one week later is found effective.

7. Stem Borer
Insects bore and enter in to the main stem at 5-6 cm above from the ground level. Incidence of this pest is mainly during early stages, flowering stage. Due to stem damage plant growth will be restricted and plants start slowly wilting. Damage by this insect leads to inadequate supply of food and water which resulting in death of the plants.


  • Changing crop patterns like not growing chilli after brinjal will help up to some extent in prevention.
  • Destroying the infected plants.
  • Application of Choloropiriphos 2.5 ml or Thiodicarb 1 g by mixing in 1 litre of water.

Disease Management
1. Damping off (Pythium aphanidermatum)
Disease of nursery beds and young seedlings resulting in reduced seed germination and poor stand of seedlings. Very high seedling mortality 25-75%. Infected areas turn brown and rot. Plants shrivel and collapse as a result of softening of tissues.


  • Raising nursery in light soil with proper drainage
  • Rabbing – burning farm trash on the surface of the beds
  • Sowing seed on raised beds of 6-8” high (15cm)
  • Using optimum seed rate of 650 g/cent
  • Seed treatment with Thiram or Captan @ 2-3 g/kg.
  • Soil drenching with Bordeaux mixture 1% or Copper oxychloride 0.3% or Metalaxyl (Ridomil) 0.2%
  • Biocontrol with Trichoderma viride and T. harzianum
  • Raising modern nurseries in portrays under controlled conditions in polyhouses

2. Die-back and fruit rot (Colletotrichum capsici )
Infects young branches and flowers results in flower drop. Branches start drying from the tips. Balck spots appear on ripened fruits and leads to rotting of fruits. Severe in Guntur and Krishna districts.


  • Seed treatment with Captan or Thiram 3-4g/kg
  • Collect seeds only form fruits without infection
  • Avoid intercropping with susceptible turmeric cultivars
  • Collect and destroy all infected plant parts
  • Removal and destruction of Solanaceous weed hosts and infected plant debris
  • Spray three times with Captan 1.5% or Mancozeb@0.25% just before flowering, at fruit formation stage and 15 days after second spray

3. Bacterial leaf spot (Xanthomoas campestris pv. Vesicatoria)
Leaves, fruits and stems are affected, Lesions on leaf begin as circular, water soaked spots, Spots become necrotic with brown center with chlorotic borders, Enlarged spots may develop straw coloured centres, Lesions are slightly raised on lower leaf surface, Severely spotted leaves turn yellow and drop, Raised brown lesions appear on fruits, Narrow elongated lesions or streaks may develop on stems.


  • Seeds should be collected from healthy fruits
  • Seed treatment with Copper oxychloride 2g/kg seed
  • Field sanitation by removal and destruction of infected plant debris
  • Add 1g Streptocycline or 2g Plantomycin to 10 litres of water and mix 3g of Copper oxychloride per litre of water and spray twice at 10 days interval

4. Cercospora leaf spot (Cercospora capsici)
Circular spots with brown margins and grey centre appear on leaves, The spots enlarge and coalesce with others, The central portion of the spot becomes white and the leaves turn yellow and defoliate, Sometimes central portion of spot drops off, Spots also appear on stems and twigs as dark brown, irregular lesions with whitish centers, In severe cases die-back of twigs occur.

Management >

  • Seed treatment with carbendazim @ 2g/Kg seed
  • Spray Carbendazim 0.1% or Difolaton 0.15% @ 15 days interval

5. Choanephora Wet Rot (Choanephora cucurbitarum)
Plants from seedling to early flowering stage are susceptible, Being a weak parasite the fungus colonises dead or dying tissues before it actively invades living tissues, Fruit infection is observed predominantly around calyx. Infected young fruits may abort.


  • Adopt recommended spacing to maintain adequate air circulation
  • Field sanitation by destroying infected debris
  • Select the seeds from healthy fruits and treat the seed with Captan or Thiram 3g/kg seed
  • Spray Mancozeb 0.25% or Copper oxychloride 0.3%

Spraying wettable Sulphur 0.3% or Dinocap or Carbendazim or Tridemorph 0.1%.

7. Dry Root rot (Sclerotium species / Fusarium Species)
Plants get infected by the fungus in the soil and dries


  • Crop rotation practices
  • Application of Copper oxychloride at the plant base by mixing 3 g of Copper oxychloride in 1 litre water
  • Application of 2 Kg Trichoderma formulation in 90 Kg FYM and 10 Kg Neem seed powder

8. Viral disease management
a.) Leaf Curl (Gemini Virus)
Transmitted by Whiteflies. High humidity and rainy climatic conditions are favourable for whiteflies and helps in severe spread of virus. Young leaves becomes small and upward curling is observed. Leaves turn in to pale green colour, intermodal distance also decreases. Leaf curl virus symptoms resemble micro nutrient deficiency symptoms whereas deficient plants are can be observed in groups and virus infected plants spread all over the field here and there.

b.) Cucumber Mosaic Virus
Transmitted by Aphids. Restricts the plant growth and black sooty mould can be observed on leaves and pods. Decrease in chlorophyll content of leaves leading to mosaic symptoms. Downward curling along with midrib. Pods may be small or distorted.

c.) Peanut bud Necrosis Virus
Virus develops on weeds which grown on bunds like Parthenium, Abutilon indicum and transmitted by thrips. Prolonged dry period after rains increases thrips incidence. Black spots occurs on stem and leaves and gradually transforms in to stripes. Necrotic spots occur leaves resulting in leaves falling off.


For getting better yields frequent picking of ripened fruits should be dried on tarpaulin / silpaulin sheets or on raised cement platforms. We can go for 3-4 pickings for rainfed crop and 6-8 pickings for irrigated crop.
