Q: When it the best time to spray pennyroyal and what weed spray should i use?A: Pennyroyal is a weed that you may not notice on your farm until it flowers.

Enquiry from a customer regarding possible causes of slow pasture growth. This follows our phone conversation of today. Situation:11 hectares affected by poor pasture growth.  2,4-D had been applied some weeks earlier.  75kg/ha urea applied the day before Decision was applied at 50g/Ha.  That was about 4 weeks ago.  The buttercups targeted by the D..

You¹ve asked about controlling cranesbill and plantains in pasture. By cranesbill I think you¹re referring to Erodium cicutarium which is actually called storksbill but it's probably called cranesbill in some local regions.  Looks as much like a crane as it does a stork, as far as I can see.  Just check the attached weed file to be sure I am on th..

IN REPLY TO A QUESTION ABOUT THE SUITABILITY OF GRASSMATE FOR THE CONTROL OF THE CONVOLVULUS AMONGST NATIVES THAT YOU WANT TO PROTECTGrassmate is a good choice for the job, because it is effective against all the bindweeds, including field convolvulus.  And it’s not volatile, meaning that it doesn’t form a lighter than air vapour that drifts unexpe..

Triclo isn't registered for either paspalum or couch, but as you say it does kill kikuyu and there are some similarities between those species.You're going to have to try a small area and give it a couple of weeks to evaluate, before you try a larger area.  I have seen a couple of anecdotal references to triclopyr (i.e. Triclo) being effective agai..

In response to a cusomer question about lily control. I think you must be referring to Arum Lily?    But my advice is much the same for all lilies anyway. According to all the best authorities on lily control, you should not need the paraquat part of your proposed mix.  As an example go to the ARC (Auckland Regional Council) info page about the Aru..
