Good Agricultural Practices of Bitter gourd, Crop Protection : Insects & Management
Bitter gourd(Bitter Gourd (Momordica charantia) crop like other gourd crops, is attacked by certain insects and diseases in its growth and development stages starting from bitter gourd seeds stage. Weeds have also competition with bitter gourd plants.
Weed management: Bitter gourd seeds once sown in the field, no selective herbicides are available for spraying in bitter gourd family. However non selective herbicides like Gramoxone or Roundup can be sprayed before cultivation to kill grown up weeds in the main fields.
Insects
Aphids and Thrips
Aphids and thrips damage gourds plants by feeding on plant sap, and by spreading important viral diseases such as papaya ring spot, zucchini yellow mosaic, and cucumber mosaic.
For control Sucking pests [ Thrips, Aphids , Green leaf hoppers, Jassids]
Confidor Super [Imidachloprid 30.5 %] 0.3 mL/L OR Hunk [Acephate]) 2 g/litre OR Tracer [Spinosad 480 SC] 0.375 mL/L
Leaf miners
Leaf miners are small, yellow maggots that form trails or mines beneath the leaf epidermis as they feed.
For control Leaf miners
Abacin 1 mL/L OR Caldan SP – 2 gm/L OR Benevia [Cyantraniliprole] 2 mL/L + Econeem plus 1 % - 1 mL/L
Fruit fly [Melon Fly]
The fruit fly has long been a major pest of gourds. Infested fruit frequently rot, either in the field or after harvest. Attacks are severe on young developing fruit, especially under high humidity conditions after summer rains.
Periodically monitor melon fly populations through trapping. Fruit fly traps can be installed at fruit stage to bring down the fruit fly infestation on mango fruits.
Whiteflies
Whiteflies not only suck the sap but also by spreads important viral diseases such as papaya ring spot, zucchini yellow mosaic and cucumber mosaic.
For control of white flies
Prime gold [Acetamiprid] 0.5 gm/L OR Odis [Buprofezin 15% + Acephate 35% WP] 2 gm/L
Caterpillars
Cutworms which include the variegated cutworm and the black cutworm can devastate young cucumber plants by chewing through the stems at the soil line. Cutworms are active at night.
For control of cutworms,leaf, flower feeder and fruit borer
Coragen [Chlorantraniliprole] or 0.33 mL/L OR Plethora [Novaluron 5.25% + Indoxacarb] 1 mL/L or Emagold 0.5 gm/L + Econeem plus 1 % 1 mL/L
Mites
Outbreaks of red spider mites occur occasionally, especially during hot, dry weather. Spider mites feed on plant sap and prefer to live on the leaf underside. Their feeding causes stippling of white areas on the leaves.
For control of Red Spider mites
Maiden [Hexythiazox] 1.5 mL/L OR Magister [Fenazaquin] 2 ml/litre + Multiplex Kranti 2 mL/L
Root-knot nematodes
Meloidogyne incognita are microscopic roundworms that feed on the roots of plants that may attack bitter gourd crop also. Adult stages of the nematode live inside these root swellings and these root galls prevent the normal water and nutrient uptake by roots. Nematode numbers are often higher in sandy soils under warm summer weather.
For control of Nematodes in infested standing crops
- Drenching for individual plants 100 to 150 mL of following mixtures at 15 days interval
- First application: Marshal 3 mL/L + Humesol 3 mL/L + Econeem plus 1 % 2 mL/L of water
- Second application: Ekalux 3 mL/L + Multiplex Kranti 2 mL/L + Neemark 1 % 2 mL/L of water
- Through drip irrigation in 500 L of following mixtures at 15 days interval
- First application: Marshal 3 L + Humesol 3 L + Econeem plus 1 % - 2 L
- Second application: Ekalux 3 L + Multiplex Kranti L + Neemark 1 % 2 mL/L of water
