1
MSU Extension Chapter 1 Principles of Pest Management
2
MSU Extension Right of Way Areas n Highways n Utility areas n Pumping stations n Drainage ways n Railroads, airports n Paths and trails
3
MSU Extension Integrated Pest Management (IPM) uses all available tactics and strategies to manage pests. Minimal impact to the environment.
4
MSU Extension In right- of - way pest management, woody and herbaceous plant species are the major pests. Not easy to define a crop-pest relationship.-
5
MSU Extension The “crop” of right-of- ways is the services the right-of-way provides.
6
MSU Extension Right of Way IPM Components n Pest identification n Monitoring n Site specific requirements n Development & implementation of control strategies n Evaluation of effectiveness
7
MSU Extension Record Keeping n Control measures, dates n Pesticides & related info n ID of crew & equipment n Environmental conditions
8
MSU Extension Pest Management Techniques n Biological control n Cultural control n Mechanical control n Chemical control
9
MSU Extension Biological controls focus on enhancing the effects of natural enemies.
10
MSU Extension Production by plants of chemicals that inhibit the growth of nearby plants. - black walnut - quackgrass - sunflower
11
MSU Extension Cultural Controls n Time of planting n Nurse crops n Controlled burning n Mulching n Shading n Sanitation
12
MSU Extension Mechanical Control n Mechanical / manual n Mowing, trimming, cutting –mowing height must control weed plants and encourage desired vegetation
13
MSU Extension Chemical Control n Flexibility n “Brown out” n Timing.. Limited n Public Perceptions
14
MSU Extension Site Requirements & Pest Species n Will help to determine… –pesticide to use –application technique –timing –equipment selection –mixing rate and additives
15
MSU Extension Attitudes have changed. Not all woody vegetation is considered undesirable.
16
MSU Extension Environmental Concerns n Wetlands are critical sensitive to chemicals n Use extreme care to avoid exposing wetlands and surface waters to pesticides –use a anti-back flow device
17
MSU Extension Chapter 2 Weed Plants and Trees
18
MSU Extension Weed = any plant growing where it is not wanted.
19
MSU Extension Developmental Stages n Seedling n Vegetative n Seed Production n Maturity
20
MSU Extension Plant Types n Annual –summer –winter n Biennial n Perennial
21
MSU Extension Plant Classification n Grasses –monocots, fibrous root system, growth point at soil surface, annual or perennial n Sedges –similar to grasses, triangular stems, perennial
22
MSU Extension Plant Classification n Herbaceous broadleaves –annual, biennial, perennial –net like venation –dicots –diverse growth points –underground reproductive systems
23
MSU Extension Plant Classification n Vines n Brush & trees n Ferns –spore reproduction, rhizomes n Parasitic seed plants –dodder
24
MSU Extension Aquatic Plant Classification n Emergent n Floating n Submergent n Algae
25
MSU Extension Submergent plants have a thin outer layer on their leaves and are very susceptible to herbicide injury.
26
MSU Extension You must obtain a permit from DEQ (DNR) to control aquatic plants. Excluding: < 2 acres, no outlet, not RUP
27
MSU Extension Ash: black, white, green
28
MSU Extension Black locust
29
MSU Extension Boxelder: ash- leaf maple
30
MSU Extension Red maple (soft maple)
31
MSU Extension Sassafras
32
MSU Extension Black willow
33
MSU Extension Black cherry
34
MSU Extension American elm
35
MSU Extension Trembling aspen, poplar
36
MSU Extension Chicory
37
MSU Extension Cattail
38
MSU Extension Goldenrod
39
MSU Extension Wild carrot (Queen Anne’s lace)
40
MSU Extension Poison ivy
41
MSU Extension Canada thistle
42
MSU Extension Musk Thistle
43
MSU Extension Purple loosestrife
44
MSU Extension Phragmites
45
MSU Extension Chapter 3 Herbicides & Weeds
46
MSU Extension Herbicides are pesticides that control weeds.
47
MSU Extension Factors Affecting Herbicidal Action n Herbicidal action characteristics n Plant characteristics n Climatic factors
48
MSU Extension Herbicidal Action Characteristics n Foliage or root absorbed n Contact or translocated n Persistent or non- persistent n Selective or Non- selective
49
MSU Extension Plant Characteristics n Growing points n Leaf shape n Wax & cuticle n Leaf hairs
50
MSU Extension Plant Characteristics n Deactivation n Stage in life cycle n Timing of stages in life cycle
51
MSU Extension Climatic Factors n Relative humidity n Light n Precipitation n Wind n Temperatures n Length of growing season
52
MSU Extension Temperature Inversions n Ground air cooler than air above n Can suspend pesticide particles n Particles can move to non- target areas
53
MSU Extension Selective Herbicides n Foliage spraying n Basal spraying n Granular or pellet n Spotgun n Cut surface
54
MSU Extension Foliage treatments can be done from full leaf to early fall color.
55
MSU Extension Low Volume Ground Foliage Treatment n 10 to 100 gal per acre n Not treated to point of runoff n Higher concentration of active ingredient n Faster coverage n Drift can be major concern
56
MSU Extension High Volume Ground Foliage Treatments n Herbicide concentration rather than rate per acre n Spray to “drip” n Larger volumes of mix n Herbicide amount will vary considerably
57
MSU Extension Aerial Application n Helicopters used most often n Pilot must be certified in… –right-of-way –aerial application n Commonly used in rough terrain
58
MSU Extension Basal treatment can be applied any time of year, except with snow or ice.
59
MSU Extension Basal Spray Methods n Conventional basal spraying –spray to wet or run down –fuel oil carrier –lower concentrations –losing popularity F cost F odor
60
MSU Extension Basal Spray Methods n Low Volume Basal Spraying –more concentrated –not sprayed to wet –light & compact equipment –more like spray painting
61
MSU Extension Granular Application n Broadcast n Directed
62
MSU Extension Spotgun n Liquid herbicide applied to a “spot” in the root zone area. n Similar to a granular stem treatment n More effective in sparse vegetation –fewer risks to non- target plants
63
MSU Extension Cut Surface Treatments n Cut stump, frilling, hack & squirt, girdling n Errors –too much chemical –improper girdling or frilling –applying too close to desirable vegetation
64
MSU Extension Non-selective herbicides control most plant species. Many last 1+ years. Easily damage non- target plants.
65
MSU Extension Factors Affecting Non- Selective Herbicides n Soils n Moisture n Vegetation types n Soil microorganisms
66
MSU Extension Non- Selective Herbicides n Keep away from root zones of desirable plants n Do not apply to frozen ground n Be careful of residual herbicides on slopes n Use low pressure n Choose non- corrosive materials
67
MSU Extension Other Chemicals n Defoliant –removes foliage n Dessicant –dries foliage n Plant growth regulator –affects some aspect of plant development-
