Shoot fly
Atherigona soccata |
- Damage caused during the
early seedling stage,
- larvae cut the growing points,
causing dead-hearts;
- tillers do develop after
the central shoot is killed
but the yield from these
tillers is rather poor;
- commoner in earlysown
rabi or late-sown kharif crops
|
- Adjust the sowing date,
- increase the seed-rate,
- uproot and destroy infested seedlings;
- treat the seed material with
Carbofuron (20:1) ;
- or apply 3% Carbofuran, 5% Disulfoton
or 10% Phorate granules
|
Stem borers; Chilo
zonellus (par-
tellus) |
- moth, dirty brownish, nocturnal,
- caterpillars feed on foliage
and bore into the stems, causing dead-hearts;
- also tunnel the stem and
bore into earheads.
|
- Plough and destroy all the stubble
after harvest;
- apply 4% Endosulfan or carbaryl
granules or spray 0.05% Lindane
|
Sorghum midge,
Contarinia sorg-
hicola |
- The insect has assumed the
status of a serious pest
recently;
- cosmopolitan;
- the tiny pinkish fly lays eggs
inside the glumes and the
larvae feed on the ovaries,
thus preventing seed formation
|
- Burn the panicle residue and chaff
obtained after the threshing of grain to destroy the dispausing larvae;
- adopt a uniform date of sowing, and
preferably grow only one variety;
- apply 0.05% Endosulfan, 01% Carbaryl
or 0.05% Lindane sprays or dusts
|
Aphids:
Rhopal-
osiphum
maidis |
- Nymphs and adults suck the sap from
the leaves and shoots, exude honeydew, on which a sooty mould grows, giving the leaves a
black appearance and interfering with photosynthesis.
|
- Spray 0.02% Phosphamidon, 0.04%
Diazinon Methyl-demeton or Dimethoate
|
Deccan wingless
Grass-
hopper,
Colemonia sphena-
roides |
- Eggs are laid in the soil 75-200 mm
deep;
- Hoppers and adults feed on foliage, at
times causing severe defoliation of the crop;
|
- Destroy eggs in the soil by deep
ploughing soon after harvest;
- dust hoppers and adults with 5 and 10%
BHC, respectively.
|
Earhead bug,
Calocoris angus-
tatus |
- Nymphs and adult bugs suck the sap
from tender grains at the milky stage, making them chaffy ;
- commoner in southern India
|
- Dust the maturing earheads with 5% BHC
or 4% Carbaryl,
- spray 0.1% Carbaryl (W.P)
|
Sorghum shoot bug,
Peregrinus maidis |
- Nymphs and adult bugs suck the sap
from the leaves and whorls which turn pale green.
- also reported as a virus vector
|
- Spray 0.03% Phosphamidon Dimethoate
Diazinon, Monocrotophos or Methyl demeton
|
Cut
worms
Agrotis ipsilon |
- Caterpillars are generally feeders;
- cut seedlings at the soil level ;
- resowing may be necessary, when the
attack is severe
|
- Dust 10% BHC on the soil around the
plants
|
Hairy caterpillars : Amsacta moorei |
- General feeders,frequently causing
severe defoliation;
|
- Dust 10% BHC;
- Undertake organized campaigns against
the early-stage caterpillars
|
Earhead cater-
pillars :Eub-
lemma silicula |
- Occur throughout the country;
- caterpillars feed on maturing grains
|
- Dust the maturing earheads with 5% BHC
or 4% Carbaryl, or spray 0.1% Carbaryl (W.P)
|
Mites:
Oligon-
ychus indicus |
- Colonies of nymphs and adults suck the
sap from the undersurface of the leaves, causing reddish brown spots and patches
|
- Dust sulphur or spray 0.05% wettable
sulphur
|
