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.

Control of Gram pod borer in Soybean

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:-

  • Deep summer ploughing
  • Install pheromone traps at a distance of 50 Meter @ 5 traps/ha for each insect pest.
  • Clip terminal shoots on 100 days of crop growth.
  • Spray with Chloropirifos 20% EC @ 750 ml/acre or Quinolphos 25% EC @ 250 ml/acre

Contro of Diamondback Moth (DBM) in Cabbage

28/07/2018Posted on

Contro of Diamondback Moth (DBM) in Cabbage:-

Identification

  • Eggs are yellowish-white with greenish tings.
  • The caterpillars are 7-12 mm in length, pale yellowish green in colour with fine erect back hair scattered all over the body.
  • Adults are 8-10mm long greyish-brown in colour having pale whitish narrow wing inner yellow margins.
  • The adult female lays eggs on the leaves either singly or in groups.
  • White markings along the back of the fore wings which when folded from a diamond shaped pattern in adult diamond back moth.

Damage

  • Small slender green caterpillars on emergence feed on the leafs epidemics and later make holes in the leaves.
  • Severely affected leaves are completely skletonised.

Control

  • For the prevention of diamond back moth, bold mustard should be sown in 2 lines after every 25 lines of cabbage/Cauliflower.
  • Spray the crop with Profenofos 50% EC (3 ml/lit) or Spinosad 25% SC (0.5 Ml/litre ) or Indoxacarb (1.5 Ml/Litre) of water at fortnight intervals starting from 25 days after transplanting to control the pest.

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.

Potash Deficiency and Their Control in Cotton

23/07/2018Posted on

Potash deficiency and their control in Cotton  :-

Prior to peak bloom, potassium deficiency in cotton presents itself as interveinal chlorosis on older leaves. These areas of interveinal chlorosis can progress to a red/gold color on these leaves followed by necrosis and/or the onset of foliage disease symptoms Due to potash deficiency, shading of leaves is observed also boll opening is not proper. Leaves get curled and become dry.

Control:- Spray Two to three times 00:52:34 or 00:00:50 @ 100 gm per pump.

Symptoms of damage: – Larvae feed on the chlorophyll of the leaves. The eaten leaves give the appearance of whitish yellow web.

   Management

  • Deep summer ploughing.
  • Avoid pre-monsoon sowing.
  • Optimum seed rate (70-100 kg/ha) should be used.
  • Collect and destroy infested plant parts, egg masses and larva.
  • Install sex pheromone trap @10 traps/ha for early deduction of the pest.
  • Erection of bird perches @10-12/ha.
  • Field Sanitation;Remove the infested plant parts at least once in 10 days and bury them in compost pit to monitor and reduce the populations of tobacco caterpillar. Traps are used for monitoring the pest situation.
  • Install five sex pheromone traps per hectare (change septa after 3 weeks), specific for male adults of tobacco caterpillar (separate pheromone for each).
  • Apply Profenophos 50 % EC@ 400 ml/acre or quinalphos 25% EC @ 400 ml/acre
