5 What is a Weed? A plant growing where it is not wanted 66
6 The Nature of Weeds Opportunistic plants Adapted to niches within the environment Herbicides can eliminate the weed, but not the environmental conditions that provided an opportunity for that weed A paradigm shift weed control weed management
7 Weed Management Herbicides are effective means of control However... Elimination of the weed does not eliminate the environmental condition that creates a competitive advantage How heterogeneous are turfgrass environments? Current management practices assume homogeneity
8 Weeds vs. Turf Plant Competition: Light most plants compete for this Nutrients H 2 O CO 2
9 Why Do We Have Weed Problems? 1. Turfgrasses are non-native plants 2. Monocultures 3. Lack of sanitation 4. Cosmetic standards
10 Why Do We Have Weed Problems? Turfgrasses are not native (depending on where you are of course): Growing non-native vegetation is always difficult
11 Ecology 101: Why Do We Have Weed Problems? Natural Succession: Long term transition of vegetation types to a condition of stability.
12
13 Why Do We Have Weed Problems? Monocultures growth of a single species Monocultures tend to be man-made. In turf, we force mother natures hand to compete against us.
14
15 Why Do We Have Weed Problems? Lack of Sanitation and Natural Movement People (shoes) and equipment (mowers, sprayers, tillage implements) movement from site to site spread weed seeds, tubers, bulbs, rhizomes, stolons, etc. Animals, wind and rain also spread weeds.
16 Inspect sod prior to purchase
17 Many problematic weeds are introduced on container grown ornamentals
