Shoot and Fruit borer

Damage symptoms


Management
Spray of PNSPE (40 g/l) or Neem soap (10 g/l) at 7-10 days interval or Cypermethrin 10 EC (1.5 ml/l) or Emamectin Benzoate 5 SG (0.3 ml/l) or Fenvalerate 20 EC (0.5 ml/l) or Lambda-Cyhalothrin 5 EC ( 0.75 ml/l) or Phosalone 35 EC (2.0 ml/l) or Pyridalyl 10 EC (1.0 ml/l) or Quinalphos 25 EC (1.5ml/l)

Leaf hopper

Symptoms:
Nymphs and adults suck sap usually from the under surface of the leaves and inject toxins causing curling of leaf edges and leaves turn red or brown called as ‘Hopper Burn’. The leaves dry up and shed

Management : Apply neem cake @100 kg/acre to beds after germination only.
Sprays PNSPE (40 g/l) or Neem soap (10 g/l) at 7-10 days interval
or
spray Imidacloprid (0.3ml/l) or Thiamethoxam (0.3g/l) (only once before flowering) or Quinalphos 25 EC (1.5 ml/l) or Dimethoate 30 EC (3 ml/l)

Aphids

Symptoms
 Aphids can attain very high densities on young plant tissue, causing water stress, wilting, and reduced growth rate of the plant
Management : Spray PNSPE (4 %) or Acetamiprid (0.15g/l) or Imidacloprid

Red spider mites

The nymph and adults are red in color. Its infestation is severe in dry and warm atmosphere.
The nymph and adult suck the cell saps from under surface of the leaf and ultimately cause defoliation.
The leaf dried and dropped away incase of severe infestation. Colonies of red mites are found feeding on ventral surface of leaves under protective cover of fine silken webs, resulting in yellow spots on dorsal surface of leaves

Ants:
Ants can be very destructive to okra pods. Ants feed on the moisture and sugar content of okra. These so cause discoloration or distortion of plant

Management of nematodes in papaya

Okra is highly susceptible to root-knot nematodes : Meloidogyne incognata 
Root-knot nematodes such as Meloidogyne incognita and M. javanica are devastating pests of okra causing a yield loss of 28 – 43%. These nematodes feed on root-system and damage them extensively. They make the plant weak and also vulnerable for the infection by secondary pathogens (soil borne pathogenic fungi and bacteria). Nematode damages also results into the breakdown of the resistance against pathogenic fungi and bacteria. 

Management of nematodes in okra

Application in new planting 

Pre-coat seeds with biopesticide before sowing.
• Add biopesticide Pseudomonas fluorescens at 20 ml/kg or 20 g/kg seed.  

• Enrichment of FYM with bio-pesticides: Mix two kg each of Paecilomyces lilacinus, Pseudomonas fluorescens and Trichoderma harzianum / T. viride in one ton of FYM and leave it in shade for 15 days at 25 – 30% moisture for multiplication of beneficial microbes.
• Soil has to be incorporated with 20 – 30 tons of FYM enriched with bio-pesticides before sowing.

Enrich neem cake with bio-pesticides: Mix two kg of each of Paecilomyces lilacinus, Pseudomonas fluorescens and Trichoderma harzianum / T. viride in one ton of neem cake and leave it in shade for 15 days at 25 – 30% moisture for multiplication of beneficial microbes.

• Apply neem cake enriched with biopesticides in standing crop at 50 g/ m2 once in a month.

• Mix 20 kg of enriched neem cake mixture in 200 lit water, leave it for two days and this can be used for drenching beds @ 2 lit/ m2 or filter it thoroughly and use it for spraying the foliage or sending along the drip, once in a month.

• Spray Arka Plant Growth Promoter and Yield Enhancer (Pseudomonas fluorescens + Trichoderma harzianum) at 5 ml or 5g/lit, once in a month.
Or send along the drip, Arka Plant Growth Promoter and Yield Enhancer (Pseudomonas fluorescens + Trichoderma harzianum) at 5 ml or 5g/lit, once in a month.
