Pesticide Sensitive Crops and Habitats Registry Implementation Results
Goal:Enable communications that promote pesticide
sensitive site awareness and stewardship activities between stewards of at-risk resources, producers of pesticide sensitive crops and pesticide applicator
communities
User Communities•Producers of pesticide sensitive crops•Pesticide applicators•Stewards of at-risk resources
Voluntary registry website is interactive
Developed by Purdue Agriculture and Biological Engineering in cooperation with Office of Indiana State Chemist.
Types of sites on DriftWatch map?
• Locations of pesticide sensitive crops•Beehives, grapes, certified organic, fruits, tomatoes,
vegetables, nursery crops, melons, xmas trees, etc…
• State identified at-risk resources•Source water for community drinking water supplies
•Endangered or threatened species habitats
Indiana Sensitive Crop Registry areas integrated with Google MapTM
How DriftWatch WorksGoogle MapsTM registry website
Producer voluntarily enrolls location of pesticide sensitive crop areas > ½ acre production
1. Provide contact information2. Identifies sensitive crop type3. Sketches a polygon around their field(s)4. Saves field polygon and contact information – done!
Producer uses
mouse to sketch
field boundary
How DriftWatch Works
Data steward - provides quality control of registry content1. Receives information provided by producer2. Performs quality control review3. Accepts/rejects producer information into DriftWatch registry 4. Acceptance adds field to public website www.driftwatch.org5. Producer receives email confirmation6. Registered pesticide applicators receive email notice of new
sensitive crop within designated area of interest (digest)
How DriftWatch WorksGoogle MapsTM registry website
Applicators – view locations of sensitive areas1. Provide contact information (optional)
2. Identify location(s) of interest (optional)
3. Automated emails alert applicator(s) that a new producer entry in designated area was registered (if applicator is registered)
4. DriftWatch “No Drift Zone” field sign supports local awareness
5. DriftWatch website map available to public
Sensitive Crop Registry participants may also purchase field signs to identify their crop areas
“ Since participating in DriftWatch, our commercial tomato producers have experienced a precipitous drop in claims due to drift.
2008 - >$750,000 claims due to drift2009 - Drift incidents reduced 50%, damage reduced 90%2010 - Negligible damage due to drift”
- Steve Smith, Director of Agriculture Red Gold
“There are no communication methods as efficient or easy to use as the DriftWatch mapsite available to commercial applicators.
Step 1 - pesticide application order is placedStep 2 - immediately enter address in DriftWatch map search toolStep 3 - determine sensitive areas within 3 seconds located in the vicinity
of our intended field application area. ”
