2. What is IDM
(Integrated Disease Management)
Integreted disease management is the
practice of using a range of measures to
prevent and manage diseases in crops.
IDM program implies all the available disease
Management approaches including cultural,
biological and chemical control with the main
Objective to keep the disease incidence
below
8. Chick Pea
Major foliar diseases of potential economic
importance in chickpea are Ascochyta Blight and
Botrytis Grey Mould.
A combination of a moderately resistant variety
And 2 sprays of chlorothalonil,one during the
Seedling stage and another at the early podding
Stage provide the most economical field control
Of Ascochyta Blight
10. Chick Pea
In Bangladesh, an IDM package, comprising
cultivation of the Botrytis Grey Mould tolerant
genotype “Avarodhi”, soil application of
diammonium phosphate,wider row spacing, seed
treatement with carbendazim+thiram(2g/kg seed)
And need based foliar application of carbendazim,
Has been devised.
12. Lentil
Ascochyta Blight, Rust and Powdery Mildew are
economically important foliar diseases of Lentil.
Integrated mmanagement of rust includes
control of volunteer plants over the summer and
removal of infected lentil debris.it is advisable
to use clean seeds without rust
contaminations,and to treat the seed with a
suitable fungicide such as diclobutrazole.
14. Lentil
Preventive fungicide sprays of mancozeb at
early disease development stage have been
recommended.
The use of host plant resistance is the best
means of rust management.Several rust
resistant cultivars have been released in
different countries, with resistance
originally identified at ICARDA,Syria and in
India
15. Cow Pea
Diseases like Cercospora leaf spot,Cowpea
golden mosaic and Cowpea aphid-borne mosaic
are of potential economic importance.
The disease can be controlled by combining
resistant varieties and spray of fungicides such
as benomyl and captafol post flowering.
20. Potato
The major diseases that often plague potato
storages include: Pink rot, Pythium leak,late
blight,dry rot, silver scurf, and black dot.
Some disease cause more severe damage and
progress more rapidly than other
21. Potato
Late Blight affects leaves, stems and tubers.
On leaves it appears as pale green, irregular
water soaked spots.
Tuber infection starts as a shallow,reddish
brown, dry rot which spreads irregularly
from the surface through the flesh.This
disease causes heavy losses.
23. Potato
Use disease-free seed, remove infected
tubers, etc.
Avoid irrigation during rainy days.
Hilly regions one spray of Metalaxyl-based
fungicides and 2-3 sprays of Mancozeb are
required.
Grow late blight-resistant varieties- Kufri
Sutlej, Kufri Badshah and Kufri Jawahar.
24. Sweet potato
Disease like Alternaria leaf spot & Leaf and
steam blight are Fungal disease.
Brown lesions on leaves with concentric rings
resembling a target.defoliation may occur.
For management destroy all sweet potato
crop residue immediately; tolerant sweet
potato varieties where available; Apply
appropriate fungicide prior to planting.
26. Cassava
Fungal disease like Anthracnose, White Leaf
Spot, etc
Soft parts of plant become twisted and
distorted.diffuse white spots on upper
surface of leaves.
For management remove leaves and crop
debris from around plants to prevent disese
spreading;
28. Yam
Yam mosaic virus can be spread through
infected planting material and by aphid
vectors.
Spray field and surrounding areas with
imidacloprid at 5-7ml/15L of water to
control aphids if vector population
persists.A systemic neonicotinoid
insecticides
