Transcript of Copy of ww 2nd prezi

hay, grass clippings, leaves
rock & shell
even rubber types looks good! hand weeding
eat 'em!
water & fire germination to death in a single season
plant's only mode of reproduction is seed
seed production, viability & dispersal are all aimed at increasing survival regulatory designation as a weed
overwhelms native community of plants
often introduced by humans
no natural predators, biological or cultural controls to keep them in check
control of their sale/distribution weeds compete for water, sunlight & nutrients
weeds have the upper hand
weeds harbor pests & disease feels good! why weed? what is a weed? intro control the weeds weeding gives plants
a fighting chance! definition of a weed
"undesirable, unattractive, troublesome ... especially one growing where it isn't wanted" "The best way to make sure you are removing a weed and not a valuable plant is to pull on it ... if it comes out of the ground easily, it is a valuable plant."
- Anonymous "official" weeds if you consider it a weed, then it's your weed! annuals & biennials perennials can reproduce via seed AND vegetatively
rooting systems that store energy
among the most difficult weeds to manage because it's there! but how? herbicidal mechanical boiling water -cooks the weeds
-risky to neighboring plants
-risky to fingers & toes chickweed MANAGE the weeds integrated pest management keep an eye on your weeds & decide when to act get to know your weeds prevent your weeds control them
specific to your garden & your priorities
aesthetics? budget? plant health?
be ready to take action identify & understand their culture cultural practices
physical barriers
herbicides as a last resort get started weeding
herbicides as a last resort evaluate & adjust just like your garden, ipm is a work in progress. prevent the weeds cultural measures herbicidal prevention "modify the garden environment"

garden sanitation: keep it clean
check new plants for stowaways
select well-behaved additions
cover bare or disturbed soil "pre-emergent:" suppresses seed germination
synthetic: triflurilan
organic: corn gluten meal mulch benefits proper use "post-emergent:" applied to plant foliage
synthetic: glysophate
organic: essential oils, pelargonic acid, vinegar clubroot disease gardeners are more mentally active & happier
just 30 minutes of weeding can burn up to 180 calories
improved hand strength & pinch force shepherd's purse capsella bursa pastoris it's subjective! creeping jenny taraxacum officinale rosa multiflora vinca minor suppresses growth & germination moderates soil temps
maintains moisture
slows erosion
provides organic matter
improves sanitation
adds unity to the garden timing: after planting or after clearing new ground
mulch only when needed
don't bury your plants! stellaria cucumber mosaic virus commelina benghalensis autumn olive lysimachia nummularia garlic mustard polygonum cuspidatum japanese knotweed wild mustard kudzu: "the plant that ate the South" houttuynia
cordata purslane
portulaca oleracea 150K seeds per plant shepherd's purse
capsella bursa pastoris 52K seeds per plant redroot pigweed
amaranthus retroflexus 117K seeds per plant soil seed bank lambsquarters
chenopodium album viable up to 40 years! galium aparine "stickywilly" creeping perennial reproduce via creeping roots, rhizomes, stolons bermuda grass
cynodon dactylon yellow nutsedge
cyperus esculentus ground ivy
glechoma hederacea japanese
hori-hori knife angle
weeder flame
weeding give ipm a try never too late to start
identify your problem garden weeds & spots
get to know your weeds, make friends
keep the pressure on! broadleaf plantain
plantago major curly dock
rumex crispus dandelion
taraxacum officinale produce new plants when cut or injured simple perennial landscape fabric is
NOT your friend! landscape fabric
is NOT your friend! 98 to 3,068 viable weed seeds in a square foot of soil your plants need your help! Making Friends
with Weeds dandelion developed in response to overuse of agricultural pesticides
simple & common sense
monitor & understand the pest, decide when management is required
lowest-impact, lowest-risk methods used first
goal is management, NOT eradication pokeweed
americana "vigorous"
is French
for"weed" physical barriers use physical obstacles to prevent the spread of weeds
cut strong bed borders
use mulch avoid
volcano! prevalent since the 1940s
cheap, easy & EFFECTIVE
health & environmental concerns
disagreement as to safety herbicides on
your mind? LAST RESORT
in ipm approach! please ...
read the label! "salted" in, watered to activate
"broad spectrum, non-selective" (suppresses germination of wanted seeds too) triflurilan powdery byproduct of corn milling
dries out seed, inhibiting germination
N-P-K ratio of 9-1-0, or 10% nitrogen by weight
application, use generally same as Triflurilan corn gluten meal your weeds have something to say ... aphids stellaria media chickweed tropical spiderwort periwinkle multiflora rose purple loosestrife lythrum salicaria want it
weed it alliaria petiolata sinapis arvensis elaeagnus umbellata regulation of weeds Federal: "NOXIOUS"
