Try a cou­ple of meth­ods

Central and North Burnett Times - - RURAL WEEKLY - PAUL MCINTOSH

I DID pre­dict that we would have a large suite of weeds af­ter the del­uge of rain a cou­ple of weeks ago.

This plethora of sum­mer and win­ter weeds that we are now see­ing in our pas­tures, our cul­ti­va­tions and even in our house yards, re­ally are tak­ing ad­van­tage of bare ar­eas in our var­i­ous si­t­u­a­tions.

I was re­cently view­ing a friend’s pas­ture pad­dock and was not overly sur­prised that the dry and hot sum­mer we have just been through, cou­pled with graz­ing prac­tices by live­stock and roos, had left very lit­tle pas­ture veg­e­ta­tion.

Also these sur­viv­ing plants with the size shrink­age and re­duced num­ber per square me­tre of the­ses use­ful grasses, had there­fore left lots of bare ground.

Need­less to say af­ter the sig­nif­i­cant rain­fall many of us re­ceived, these bare ar­eas are now full of new weeds.

Not just the “plants out of place” def­i­ni­tion of a weed, but real weeds like stra­mo­nium, noo­goora, ama­ran­thus, clock­weed, flea­bane, and that pretty yel­low flow­ered turnip of course.

I imag­ine in cen­tral Queens­land a sim­i­lar weed spec­trum cou­pled with parthe­nium, plus many oth­ers.

The ob­vi­ous an­swer is to spray them with a suit­able her­bi­cide, how­ever some care needs to be taken with the choice of prod­uct and any live­stock graz­ing with­hold­ing pe­ri­ods.

The old days of the 70 and 80s are gone as far as just spray­ing the pad­docks while the cows are up the other end.

I have reg­u­larly rec­om­mended in grass pas­ture pad­docks only, Brushoff/Lynx/As­so­ciate plus many other gener­ics, which all have the same ac­tive in­gre­di­ent (met­sul­furon methyl) in this Group B mode of ac­tion clas­si­fi­ca­tion.

No­tice I said grass pas­tures.

If you have a broadleaf pas­ture plant like a medic vis­i­ble, then you will do some dam­age or out­right kill this part of your pas­ture mix with the above men­tioned prod­ucts.

Now this met­sul­furon methyl her­bi­cide is handy and a very eco­nomic prod­uct, how­ever it does not con­trol ev­ery broadleaf plant you have, so you may need to do a weed spec­trum as­sess­ment and con­sider tank mix­ing with an­other broadleaf her­bi­cide.

A broadleaf prod­uct like 24-D or Flurox­ypyr, both from the Group I class, maybe tank mixed with your sul­fony­lurea prod­uct.

That all sounds fairly easy, how­ever I do not want you run­ning out spray­ing this mix all over the coun­try­side, par­tic­u­larly in those peri ur­ban lo­ca­tions. By peri ur­ban I re­fer to those edge of towns and cities area, where weed con­trol goes out the door.

These si­t­u­a­tions plus other pad­docks with broadleaf sen­si­tive plants right next door, do need se­ri­ous avoid­ance by you with your spray­ing en­deav­ours.

The avoid­ance is that of spray drift.

Spray drift is those tiny lit­tle aerosol size droplets that get caught in the winds and breezes, to go over the fence onto some­one cab­bages, toma­toes, petu­nias, roses, onions, let­tuce, grapes, cot­ton, sun­flow­ers plus many other broadleaf plant species.

That is where chip hoes come in handy.

So whilst I dis­like see­ing weed heaven in var­i­ous ar­eas, spray drift needs to avoided at any­time.

So give your grass plants a fair go and get rid of by any means you choose , of those mois­ture suck­ing and very com­pet­i­tive weeds.
