You asked if it’s OK to apply Gibber900  to a paddock grazed 14 days ago.

 

The answer is yes, though the full benefit does take about 18 days or so from application, so to some extent it depends how long before you want to use that paddock again.  If you can wait 18-21 days after you’ve sprayed, it will give you the Full Monty as far as the grass boost effect goes.  The reason why we say that it’s ideal to spray 1-3 days after grazing is because at that early stage the grass is doing its best to recover quickly, so that makes it the optimum point to add the boost effect.  And of course the second reason is that generally people using a rotational grazing system want to get back to that pasture sooner than the 32 days-odd that you’ll be looking at (that is, 14 days before spraying plus another 18 for maximum effect to take place).

 

However, there’s still plenty of effect available even if you are spraying later, as you wish to.  It might be a little less than the boost you’d have got from spraying earlier, but there’s not likely to be all that much reduction overall, just as long as you can give it the 18 days (or as much of it as you can allow) after spraying.  The boost effect tends to begin to become noticeable from about 7 days after spraying, and then it accelerates further during the subsequent 10-12 days or so.  At that point you have about the maximum additional growth that you’ll be getting.

 

You also asked if there’s any withholding period for milking cows.  No, there’s none.  You could graze the next day after spraying if you wanted to, although of course that would be pointless in that it would not allow any extra growth to occur!  But from a stock safety and milk quality point of view, there’s no withholding required at all.
