Sharadchandra P. Marahatta 1 Bal Krishna Gautam 2 Sundar Tiwari 3 Approaches to improve the effectiveness of Farmers Field School for vegetable IPM 1 Kaua‘i Community College, University of Hawai‘i 2 Louisiana State University 3 Institute of Agriculture and Animal Sciences, Nepal This talk was presented at the 60 th Annual Meeting of the Entomological Society of America, November 11-14, 2012, Knoxville, TN.

Problem in Asian Rice :

Problem in Asian Rice 2

The history:

The history 3 IPM program initiation following brown plant hopper, Nilaparvata lugens , (BPH) outbreak in rice, adult IPM education through Farmers’ Field School (FFS) modeled after Indonesian experience, very successful PRINCIPLES OF IPM FFS Grow healthy crop Conserve natural enemies Observe field regularly Make farmer expert

More pesticides in vegetables:

Rice vs vegetable:

Rice vs vegetable RICE More stable system Minimal use of pesticide Season long Single harvest, at the end of the season 5 VEGETABLE Less stable system Frequent use of pesticide Short term Multiple harvest, throughout the crop cycle

Vegetable Production:

Vegetable Production Usually concentrated around urban market center High value crop Fresh produce Risk of pesticide residue Usually near residence Higher exposure to women and children Smaller farms, Intensive cropping, low risk bearing ability 6

Vegetable pest:

Vegetable pest Range of crops: Cole crops to tree vegetables Variety of pests Insects (defoliators, borers and suckers) Diseases (club root, late blight) Weeds (broad leaf, grasses, and sedges) Little information available on: Field ecology Natural enemies Pesticide resistance 7

Vegetable IPM schools:

Vegetable IPM schools Crop selected: Cole crops, fruit crops and cucurbits Group approach: Mixed group (male, female farmers) Women group Student / school IPM Weekly meeting Discussion and field visits 8


approaches 9 Farmer’s Field School Student’s Field School Agro-ecosystem analysis (AESA) Management decision based on AESA results


Techniques IPM trainings on farmers field Field studies Pest survey through weekly field monitoring Insect identification through insect zoo ‘good bugs’ and ‘bad bugs’ 10

Major focus:

Major focus Pest identification Pest ecology / interaction Role of natural enemies 11

Learning environment:

Learning environment Field demonstrations / study plots: IPM practice (IP) vs conventional farmers’ practice (FP) Insect damage simulation studies Fertilizer study Team building and group dynamics exercises Cultural programs: IPM song / IPM dance 12

Learning environment:

Learning environment 13


Tools Traps Fruit fly trap and other pheromone traps Yellow sticky trap Dirty trap Compost tea 14

Efforts to develop vegetable model:

Liquid fertilizer for crop growth and pest reduction (?) Yellow sticky traps against common insects Efforts to develop vegetable model


Impacts Knowledge of ‘good bug’ and ‘bad bug’ Additional IPM activities through women group vs mixed group or students Use of tools Traps Insect zoo 16


Limitations Inadequate materials / instruments Inadequate technologies Confusion: IPM and organic practices 17

Conclusions / Recommendations:

Conclusions / Recommendations It is suggested to involve the student IPM school graduates in vegetable IPM extension. Compared to chemical pesticides, IPM technologies are less effective. Thus, research to invent effective IPM tools should be continued.
