Case Wrap-up

The Problem Backflow
6
What can YOU do?
  • Air gap
  • Water tank

7
Atrazine Use and Surface Water
Concerns

8
Atrazine Monitoring Program
  • In atrazine monitoring program, watersheds in a
    5-year 2 step plan
  • 1) Water analyzed on 90 day rolling average.
    If average is exceeded, mitigation plan required
  • 2) If average exceeded second time within 5
    years, atrazine use will be banned in watershed

10
Factors affecting atrazine movement
  • Precipitation
  • Distance to surface water
  • Tile
  • Tillage
  • Follow the Label

OSU Extension
11
Atrazine Label Setback Requirements Wells,
Sinkholes
Mix and load 50' away from well heads and sink
holes and tile inlets.
12
Atrazine Label Setback Requirements Standpipe
Do not apply atrazine within 66 feet of any
standpipe in a terraced field if the tile outlet
is within 66 feet of a point where surface water
runoff from the field through the outlet
enters a stream or river unless . . .
13
Standpipe setback
  • You may apply atrazine to an entire terraced
    field with tile outlets if
  • Immediate incorporation to a 2-3?depth
  • No-till or other high residue crop management
    practices are used

14
Atrazine Label Setback Requirements Surface
water
Do not mix or load within 50' of stream or
river Do not apply within 66' where runoff enters
a stream or river Do not apply 200' of lake or
reservoir
15
Weed Management Tactics
  • Use herbicide-resistant corn varieties
  • Use atrazine post emergence
  • Zone herbicide application
  • Substitute other products
  • Reduce soil-applied rates and tank mix with
    atrazine
  • Incorporate atrazine

16
  • Concerns of atrazine
  • Label setbacks
  • Weed control strategies
  • Assistance is available

17
Pesticide Bulk Storage
18
Bulk Pesticides
Liquid
  • Any container that has the potential to hold more
    than 55 gallons of liquid pesticide.
  • Dry pesticide stored undivided in excess of 100
    pounds.

Dry
19
Minibulks
  • Minibulk tanks (55 to 400 gallons) kept more than
    30 days are considered bulk storage.

20
Registration
  • Register with OISCPhone 765/494-1492 and
    www.isco.purdue.edu/index_fert.htm
  • Same form for both Pesticide and Fertilizer
  • No cost for registration
  • Renewed annually

21
Mix load pad
22
Compliance Benefits
  • Tax credit
  • contact OISC
  • Safeguards investment
  • Protects the environment
  • Saves money buying in bulk quantities
  • Lower insurance rates possible

23
The Whys and Hows of Pesticide Recordkeeping
24
Reasons to keep pesticide records
  • Aids in management decisions
  • Provides liability protection
  • Used to justify insurance claims
  • Requested in real estate transfers
  • Assists medical personnel
  • Part of a pest management plan
  • Required for restricted-use pesticides

25
Private applicator record requirements
  • Records kept for 2 years.
  • Recorded within 30 days of application.
  • No specific form required.

26
RUP required information
  • Location
  • Applicator name and permit number
  • Date of application
  • Crop
  • Pest
  • Acres treated
  • Rate
  • Total amount used
  • Brand name and formulation
  • Manufacturer
  • EPA registration number

27
  • Direct On-site Supervision
  • at site
  • in line of vision

28
The second method of direct supervision requires
the supervising private applicator to
  • examine the site with the noncertified applicator
    prior to the RUP application AND
  • be within 30 miles of the RUP application site
    AND
  • be continuously within voice contact with the
    noncertified applicator during the application.

29
Continuous voice contact
  • Telephone
  • Cell phone
  • Two-way radio
  • Walkie-talkie
  • NOT Beepersor Pagers

30
Minimizing spray drift is in the best interests
of everyone. Do your part to keep agrichemical
applications on target.

31
Wind
  • 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 are never recommended.

32
Factors Continued
  • Weather, etc.
  • Air movement (direction and velocity)
  • Temperature humidity
  • Air stability/inversions
  • Topography

33
Factors Continued
  • Weather, etc.
  • Air movement (direction and velocity)
  • Temperature humidity
  • Air stability/inversions
  • Topography

34
Field Conditions
  • What are the adjacent crops?
  • Is the field close to houses or a town?
  • Is this a preventive treatment or have pest
    thresholds been reached?
  • Large, uniform fields are good candidates for
    aerial applications while small, irregular shaped
    fields suggest ground rigs.

35
Product Selection
  • Of course you must control your target pest(s).
  • You may have several options on products.
  • Understand the product chemistry!
  • Consider worker safety and restrictions.
  • Consider the effect this product may have on
    homes and gardens near the application site.
  • Consider environmental and wildlife safety.

36
Factors You Cant Control
  • Weather
  • Wind
  • (speed direction)
  • Temperature
  • Humidity
  • Susceptible crops or other non-target areas of
    concern near your application site.

37
However, Drift Potential May be High at Low Wind
Speeds
  • Because
  • Light winds (0-3 mph) tend to be
  • unpredictable and variable in direction.
  • Calm and low wind conditions may indicate
    presence of a temperature inversion.
  • Drift potential is lowest at wind speeds between
    3 and 10 mph (gentle but steady breeze) blowing
    in a safe direction.

38
Wind
  • Drift potential usually increases with increasing
    wind speed.
  • However, many factors (ex., droplet size and boom
    height) can influence drift.
  • The effects of wind are
  • reduced if small droplets
  • are minimized and the
  • application is made at the
  • proper height.
  • Use a wind gauge and
  • avoid gusty conditions.
