  The standard manufacturer stated application rate is very clearly written on the bottle, I use pistol almost every week. Read the label and work it out, not rocket science. If you HAVE done PA1 and PA6 then i cant for the life of me see why your asking the question.
  
  BTW , you shouldn't really use it on hard surfaces like a patio due to run off etc so spray the joints only if you do. Who did you do your course with..... very poor training if they haven't shown you how to work out the application rate as this is the basics of the training.

  comes out as 100sqm 45ml pistol 2 litre water does sound ok as states on label 45ml knapsack 2.5-10litre water
  
  Pro Gard said:

  400ml, is not what the label says.
  
  What rate did you get from your calculations?

  thanks paul, all advice means so much to me. so the patio will be fine with round up 450 as long as theres no run off to lawn edges drains etc...

  400ml in 16l is the rate I use.
  
  Don't spray the patio though, run off could be very damaging. It is not intended for use on hard surface. It does say this on the label so always make sure you give the label a good thorough read, there are all manor of guidelines with certain chemicals regarding animals/livestock exclusions, water courses/ditches, applications permitted per year etc as I'm sure you know from your training.

    I'm afraid I agree with PG mark. You really got to read the labels. Between the labels and training you have had you shouldn't be asking these questions.
    
    Have a read up on different chemicals available and there different uses. Then you'll be prepared for all customer requirements.

      Isn't the main reason for this forum to help others?
      
      I do agree with what Paul has to say, but I myself really struggle with numbers. I have also passed my Pa1and 2 about 10 yrs ago but still give the data sheet to my wife to callibrate.
      
      A huge part of my course at collage was health and safety, I have no problems in giving my method statements, risk assements etc etc, out to those who need it even if they havnt taken the course.

  thanks for the reply martin, your right about the forum thats why im asking, i dont think after to days training you should know everthing about pesticides, personely i dont think the coarse is long enough should be a least a week long knowing what serious damage can be done out there yes i learnt things but you never stop learning

  cheers guys for all your advice much appreciated,will take all on board,as i have done in the past 6 months since i foruately found this site thank you..
  
  Pro Gard said:

  I use it at 180ml to 16 liters for a full tank or 45ml to 8 for a half tank.
  
  IMO Pistol is best used on small and seedling weeds ie up to 2" growth.
  
  If treating large weeds then pistol would not be my first choice as it is very slow to work, I would treat them first with roundup. Then once weeds ree sprout I would spray with pistol. If you use the pistol then be sure to tell the customer that it takes around 3 weeks to take effect...... grass weeds are quickest to die.

    Didn't mean to come across unhelpful. It really is imperative to read and get to know chemicals though. Read labels, read websites, ljn discussions, yes, ask questions.
    
    In previous post it wasn't so much that you shouldn't need to ask, more that you really should now details of chemicals you are using- it is your business to know.
    
    With regards sharing risk assessment sheets etc I too have benefited from this. I wouldn't agree with allowing ones to use without pesticide training though Martin. I would assume that they would only read to get an idea. Wouldn't be much sense in using risk assessment without training!
