Weeds

"A weed is a plant in the wrong place"

It can be invasive or merely a nuisance. Most plants we call weeds are native to our prairies and survive well here. Some have been accidentally imported from other areas or countries, and grow too well in ours. Some are attractive and easy enough to pull out that they can be controlled and others must be eradicated regularly so we won't become overwhelmed.


Restricted weeds pose a serious threat and must be eradicated to prevent rapid spread. It is illegal to have them on your property.
Noxious weeds have the ability to spread rapidly and can cause severe crop loss. They should be controlled to prevent further growth spreading into cropland


Nuisance weeds are common to the province. They are found throughout the province, are often native, so are difficult or impossible to eradicate.


Lawn weed killers kill broad-leafed plants but not grasses.


Non-selective weed killers kill any plant they come in contact with.




Fungicides

Fungicides are chemical compounds or biological organisms used to kill or inhibit fungi or fungal spores.


Fungicides are chemical compounds or biological organisms used to kill or inhibit fungi or fungal spores.


Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue, & only protect the plant where the spray is deposited; translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface; systemic fungicides are taken up & redistributed through the xylem vessels to the upper parts of the plant. New leaf growth is protected for a short period.
