The importance of application time weather monitoring l.jpg
The importance of application time weather monitoring?

To avoid spraying in conditions that may result in drift!!!

  • Spotty pest control

  • Wasted chemicals

  • Off-target damage

  • More high value specialty crops

  • Urban sprawl and.....

  • Less tolerant neighbors

  • Litigious Society

  • Result-higher costs-$$$


Documentation recordkeeping l.jpg

All certified applicators are required to maintain records of federally restricted use pesticide (RUP) applications.

Documentation – Recordkeeping:


Pesticide recordkeeping requirements l.jpg
Pesticide Recordkeeping Requirements: of federally restricted use pesticide (RUP) applications.

  • Optional information ??????

    • Target pest(s)

    • Size/density of pest

    • Adjuvants

    • Application method

      • Aerial, ground, chemigation, incorporation

    • Special equipment details

      • Boom/nozzle, airplane, helicopter, banding

      • Droplet size, pressure

    • Reentry time/date

    • Environmental conditions – Actual

      • Wind speed, direction, temperature, humidity, time

How many entries?


Pesticide recordkeeping survey l.jpg
Pesticide Recordkeeping Survey of federally restricted use pesticide (RUP) applications.

Pesticide Education Program - Carol Ramsay and Carrie Foss

Washington State University

  • At-ProgramRecordkeeping Survey – Jan.–March 2002

  • number of attendees = 2,191

  • sample size = 826

  • sample is 38% of attendees

  • Post-Program Recordkeeping Survey – August 2002

  • surveys mailed = 490

  • sample size = 155

  • response rate is 32% of mailed surveys


How do you measure wind speed l.jpg

Carol Ramsay and Carrie Foss – Washington State University-2002


What measure do you use for wind speed l.jpg
What measure do you use for wind speed? of federally restricted use pesticide (RUP) applications.

  • Use words: calm, gusty, variable

    • At Program 38%

    • Post Program 33%

  • In miles per hour (or feet per second)

    • At Program 62%

    • Post Program 67%

  • Carol Ramsay and Carrie Foss – Washington State University-2002


    How do you measure wind direction l.jpg

    Carol Ramsay and Carrie Foss – Washington State University-2002


    What measure do you use for wind direction l.jpg
    What measure do you use for wind direction? of federally restricted use pesticide (RUP) applications.

    • general direction (S, SSW, ESE, W)

      • At Program 94%

      • Post Program 97%

  • compass reading (172˚)

    • At Program 6%

    • Post Program 3%

    Record keeping l.jpg
    Record keeping: of federally restricted use pesticide (RUP) applications.

    • Why am I keeping all of this information?

      • Refresh your memory

      • Safety

      • Better performance

      • Demonstrate care and concern

      • Stay ahead of the competition

      • Defend yourself!


    Weather factors of concern l.jpg
    Weather factors of concern: of federally restricted use pesticide (RUP) applications.

    • air movement (direction and velocity)

      • Topography, etc.

    • temperature and humidity

    • air stability/inversions

    Wind direction l.jpg
    Wind direction: of federally restricted use pesticide (RUP) applications.

    • Wind direction is very important

      • Know the location of sensitive areas - consider safe buffer zones.

      • Do not spray at any wind speed if it is blowing towards sensitive areas - all nozzles can drift.

      • Spray when breeze is gentle, steady, and blowing away from sensitive areas.

      • “Dead calm” conditions arenever recommended.


    Compasses l.jpg

    Determining wind direction l.jpg
    Determining wind direction: of federally restricted use pesticide (RUP) applications.

    • Compass

      • Provide magnetic description

      • Direction blowing from

      • Into your face!


    Determining wind direction17 l.jpg
    Determining wind direction: of federally restricted use pesticide (RUP) applications.

    • Point compass into the wind direction and read in degrees.


    What affects wind direction l.jpg
    What affects wind direction: of federally restricted use pesticide (RUP) applications.

    • Wind currents can drastically affect spray droplet deposition

    • Structures drastically affect wind currents

      • Wind breaks

      • Tree lines and orchards

      • Houses and barns

      • Hills and valleys


    Determining wind speeds l.jpg
    Determining wind speeds: of federally restricted use pesticide (RUP) applications.

    • Handheld devices

      • Mechanical - floating ball, wind vane

      • Electronic – spinning turbines

    • In-the-field stations
