Management of Carrot fly

12/11/2018Posted on

Management of Carrot fly:-

Damage –

  • The flies lay their eggs around the developing carrots.
  • Crop damage is caused by the creamy-yellow larvae (maggots) feeding on the outer layers of the carrot root. In autumn, they may penetrate further into the root.
  • The legless larvae are up to 10 mm in length.
  • Foliage becomes wilted and discoloured.
  • Leaves turn rusty red to scarlet with some yellowing. Rusty-brown tunnels are seen under the outer skin of mature roots.

 

Management –

  • Maintaining a 3–5-year crop rotation of all crops within the carrot family (Apiaceae), and locating these crops as far away as possible from the previous year’s crop.

  • Row cover is another method of exclusion.

  • Spray profenophos 50 EC @ 400 ml/acre.

  • Spray quinolphos 25 EC @ 300 ml/acre.

Control of Aphids in Cabbage

05/09/2018Posted on

Control of Aphids in Cabbage:-

  • Nymphs and adults are both soft bodied pear shaped, blackish in colour.
  • Colonies of these insects are found on tender shoots and sacks vital sap from the tissues.
  • Affected plants remain stunted in growth and curd formation is poor.
  • In case of severe infestation plants may completely dry up and die away.
  • The aphid produce honey dew which makes the plants sticky and favours the growth of shooty mold.
  • As a result of shooty mold a black coating is formed on affected plant parts hindering the photosynthesis and adversely affect the plants growth.
  • Slight humidity favours rapid multiplication of  this pest.
  • Grooming stages of aphids are mostly observed on the lower surface of the leaves.

Control:-

  • Spraying of the crop with one of the following insecticide
  1. Dimethoate 30 EC @ 300 Ml/ Acre
  2. Quinalphos 25 EC @ 300-400 Ml/Acre
  3. Profenophas 50% EC @ 400 Ml/Acre
  • Destroy  plant debris or remove banded grasses/weeds.
  • To prevent recurrence of the aphid population granular insecticides. like Phorate 10 G @ 4 kg/ Acre should be applied in the soil.

Management of Mealy Bug in Cotton

13/08/2018Posted on

Management of Mealy Bug in Cotton:-

  • Heavy clustering of mealy bugs usually seen under surface of leaves as a thick mat with waxy secretion.
  • Excrete copious amount of honey dew on which the fungus sooty mould grow.
  • Affected plants appear sick and black, resulting reduced fruiting capacity.

Management

  • Remove the alternate weeds hosts.
  • Monitor the incidence regularly and look for crawler emergence.
  • Take up the management at intial stage to get maximum control.
  • Wherever necessary use neem based botanical insecticides such as neem oil @ 75 ml per pump or NSKE @ 75 ml per pump.
  • Use of Dimethoate @ 30 ml/pump or Profenophos @ 40 ml/pump or Buprofezin @ 50 ml/pump may be adopted as an alternative.

Control of Fruit fly in Sponge Gourd

31/07/2018Posted on

Fruit fly in Sponge Gourd:-

  • The maggot burrow in to the fruits and suck the sap.
  • Infested fruit decay and drop.
  • The fly mainly prefers tender fruits for egg laying.
  • Ovipositional punctures caused by adults also cause injury on fruits and fruit juice oozes out.
  • This also results in distorted and malformed.
  • The maggots feed on the pulp of fruits as well as on the immature seeds and cause premature dropping of fruits.

Control:-

  • Collected and destroy infected fruits.
  • To prevent egg laying fly traps (Pheromons traps) can be set up in the yield with 1%methyl Engenol or Cintronella oil or vinegar or dextrose or Acetic acid or laetic acid.
  • Cover developing fruits with paper or polythene cover immediately after anthesis pollination.
  • Maize plants grown in rows at a distance of 8-10 cm in sponge gourd field is effective as flies rest on such tall plants.
  • Soil incorporation of cabaryl 10% dust can be made in fruit fly endemic areas.
  • Spraying of Dichlorovas @3ml/lit of water at fortnightly intervals.
  • Deep ploughing to expose hibernating stages.

Management of Chilli thrips

Symptoms:-

  • The infested leaves develop crinkles and curl upwards.
  • Elongated petiole.
  • Buds become brittle and drop down.
  • Early stage, infestation leads to stunted growth and flower production, fruit set are arrested.
Management:-

  • Do not grow chilli after sorghum.
  • Do not follow chilli and onion mixed crop.
  • Sprinkle water over the seedlings to check the multiplication of thrips.
  • Treat seeds with imidacloprid 70% WS @ 12 g/kg of seed.
  • Apply carbofuran 3% G @ 33 kg/ha or phorate 10 % G  @ 10 kg/ha or
  • Spray any one of the following insecticide.

 

             Insecticide Dose
Imidacloprid 17.8 % SL 100 ml/acre.

Symptoms of damage:-

  • The young larvae feeds on the chlorophyll of young leaves and skeletonize it.
  • They feed voraciously on the foliage in early stage,may defoliate the plant and later they feed on flowers and pods.

Management:-

  • White markings along the back of the fore wings which when folded from a diamond shaped pattern in adult diamond back moth.

Control of white grubs in Soybean and Groundnut

26/07/2018Posted on

Control of white grubs in Soybean and Groundnut:-

Symptoms of damage:

The grubs feed roots. Grubs feed on fine rootlets, resulting in pale wilted plants, dying in patches.

Management of White grubs:-

  • Bio-Control:- Soil application- For soil insect pest like White Grubs,Termite, Agrotis species etc Mix 2.0 kg to 4.0 kg Metarhizium anisopliae with 50 kg of well decomposed fym/compost/field soil and broadcast in the field of 1 acre at the time of field preparation or in standing crop. Foliar spray – Mix 2.0 kg Metarhizium anisopliae, in 150 – 200 litre of water for spray on insect pest in the standing crop of 1 acre.
  • Spray should be undertaken as a community approach and should be repeated after every rainfall till the middle of July.
  • Spraying the trees close to the field with Chlorpyriphos 20 EC @ 2 ml/lit of water soon after first monsoon showers for 3-4 days in the late evening hours kills the adult beetles and reduces root grub infestation.
  • Seed treatment with chlorpyriphos 20 EC ( 6.5 to 12.5 ml/kg seed) is found effective.
  • In case of severe infestation apply  Carbofuran 3% @ 10 kg/ Acre or Chlorpyrifos 20% EC @ 500 ml/acre or Phorate 10% G @ 10 kg/ha.
