3. WHAT IS IPM ?
o An important tool to maintain the pests population
those levels causing economic injury .
o Retain also the balance of food chain in agroecology
along with reduction of pest population .
o All available as well as possible meanses become
integrated here .
o Modern eco-friendly approach to save crops from
pests .

4. ON WHICH LIE ? - MONITORING
Principle of IPM is Monitoring –
 Field observation at 3 – 4days interval .
 Those record at 10 – 14days interval from
sowing to mid-tillering & weekly mid-tillering
onwards .
 As & when required ,observation through either
diagonal or zigzag walking .
 Walking start from a corner of field and always
in the early morning .
 25 hills thoroughly observe – 5hills at 5spots .

5. CONTD.
 Farmers should be persuaded for daily field visit
and to watch for pests and biocontrol agents .
 Observation must be recorded at each 5 - 10km
Distance
 At least 20 spots must be observed .
 Sweep nets and water-pans may also be used for
pests and biocontrol agents’ population
assesment .
 Light trap with 200w. Mercury lamp(2hrs) may
also be used .
 Pheromone trap - 5traps/Ha may be used .

6. STRATEGIES OF IPM
 Cultural :-
 Tillage
 Clean Seed
 Clean Culture
 Use of tolerant variety
 Irrigation
 Fertilization
 Crop Spacing
 Crop Rotation
 Intercropping
 Trap Crops
 Pruning & thining and Training
 Time of Sowing & Harvesting

7. CONTD.
 Physical :-
 Hot or Cold teratment
 Light/Pheromone Trap
 Bird Percher
 Moisture

8. CONTD.
 Mechanical :-
 Hand Picking
 Exclusion by Screens and Barries
 Trapping and Suction Devices

9. CONTD.
 Biological :-
Introduction, Conservation , augmentation and
inundation of natural enemies as follow -

10. Orb spider ; Long-jawed spider
Lynx spider ; Wolf(Lycosid) spider

11. CONTD.

12. Water Treader ; Water Strider

13. PARASITE WASP
Xanthopimla ; Charops sp.

14. CONTD.
Chemical :-
It may be taken up –
 Unless former another methods is not taken time
to time .
 Whereas , in spite of taking formers timely , they
bychance become failure
 exceptionally Disease management , because –
“Prevention is better than cure”

15. CONTD.
Concept of injury levels(ETL/EIL) are so
important to take up chemical measure -
