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 .
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 .
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 .
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
CONTD.
Physical :- Hot or Cold teratment
Light/Pheromone Trap
Bird Percher
Moisture
CONTD.
Mechanical :- Hand Picking
Exclusion by Screens and Barries
Trapping and Suction Devices
CONTD.
Biological :- Introduction, Conservation , augmentation and
inundation of natural enemies as follow -

Water Treader ; Water Strider
PARASITE WASP Xanthopimla ; Charops sp.

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