Transcript of IRM in Rice and Vegetables flipchart
• Utilizes various tactics or control methods (i.e.cultural/mechanical, biological or bio-control,and chemical) in a harmonious and compatibleway.
• Emphasizes management of pest population rather than the old concept of total eradication.
• Keeping pest population low (below Economic Threshold Level).
Integrated Pest Management (IPM)
Cultural/Mechanical• Sanitation• Synchronized Planting• Crop Rotation • Fallowing • Use of Resistant Varieties• Minimum Tillage• Proper Fertilization (eg. Nitrogen)
Biological / Bio-control• Knowing the Natural Enemies
of the pest• Diadegma and Cotesia for
cabbage DBM control• Spiders, Beetles• Trichogramma• Bacillus spp.
Chemical• Need – based approach in the use of pesticides• High risk pests include Diamond Back Moth, Hoppers (BPH,
MLH), Eggplant Fruit and Shoot Borer, Thrips• Continuous use of pesticides of same of mode of action (MoA)
leads to development of resistance • Role of Insecticide Resistance Management (IRM)
Integrated Pest Management (IPM)
Why didn’t it work this time?
1. Insecticides FARMERS use today remain EFFECTIVE for their use.
2. FARMERS Save MoneyNo need to increase number or volume of insecticide applications.No need for “cocktail” to control a single pest.
3. FARMERS Get More ProductionGood pest management / good crop protection / better income.
4. FARMERS Protect their Environment and LandLess active ingredient applied to ecosystem.
Benefits of IRM to FARMERS
Insecticide Resistance occurs from the continuous use of insecticides with the same mode of action (MoA) resulting in the selection (ang natitira) of insect populations that are resistant (hindi na tinatablan) to those insecticides.

Survivors Reproduce
Continuous use of the same Mode of Action (MoA) removes the very susceptible individuals leaving a tolerant population that survives the insecticide application.

1. Incorporate IPM practices
2. Follow GAP Principles
3. Know the mode of action (MoA) of insecticide products / brands
4. Rotate Insecticide MoA group / NOT Active Ingredient (AI) / NOT brands
To Avoid Development of Insecticide Resistance
Identify the Pest
Monitor Pest populations
Use the right , registered insecticides, only when needed
Use only recommended label dose when using chemical insecticides
Seek expert advise (e.g. Extension workers, industry)
1. Incorporate IPM practices when using chemical insecticides
Under Dose:Kills most Susceptible but many RS and RR survive
Label Dosage: Optimal ControlSmall number of RR survive
2. Follow Good Agricultural Practice (GAP) Principles

3. Know your Pesticide MoA

4. Rotate by Mode of Action (MoA)
Insecticide Application
Do’s and Don’t’s
Do not use a single MoA continuously.
You may use products of the same MoA within the same insect generation.
Use only recommended label dose. Do not under dose.
Apply a product with a different MoA for each successive insect pest generation.
Do not expose more than 50% of the crop duration to products with the same MoA.
