LEARN how to control weeds

Organic Herbicides

These herbicides are manufactured from naturally occurring compounds. Concentrated forms of vinegar and soapy fatty acids are examples of organic herbicides. To be fully recognised to be used in the production of organically certified foods such herbicides must be externally accredited. The advantages of using organic herbicides are obvious but it is important to note that "organic" does not necessary mean safe to humans. Extreme care and appropriate personal protection equipment must be used when handing and using organic herbicides.

Clean up existing weed growth with.....

Bioweed, a certified organic herbicide distributed by Weed Force.

Organic herbicides work by desicating or "burning" foliage of weeds with little if any translocation ( ie there is almost no movement of the weed killer to the roots). This means that these herbicides generally are only effective on annual or shallow rooted weeds. Conventional herbicides like Evict 700and Metmac 600 move throughout the weed are generally required to control deep rooted perennial and woody weeds. If organic herbicides are applied to deep rooted perennial and woody weeds you can expect some initial foliage burn off followed by rapid regrowth.

The bottom line when considering to use an organic weed killer is that they are very expensive compared with conventional herbicides however they can be a useful alternative to control spectrums of shallow rooted annual weeds. If deep rooted annual, perennial or woody weeds are present you are likely to be very disappointed and are better to consider Glymac 360 or Evict 700herbicides.

SPRAY tips and hints

Accuracy is the key to the safe and effective use of weed killers. 

Calibrate your sprayer to know how much water it will apply to a given area. In this way you can accurately determine the appropriate rate of weed killer required to be mixed in the sprayer tank.
