  • 10 ppm – Standard Solution (1 ml of ‘Planofix’ in 4.5 litres of water)
( 1 / 4.5 = 0.022 ml i.e. 22 ppm (0.0022% is a wrong calculation).
100 ppm – (10 ml of ‘Planofix’ in 4.5 litres of water)
  • Should be sprayed during cool part of the day and avoid excessive hot day.
  • Though compatible with most pesticides, individual application will give good results. Compatible with 1% Urea as foliar nutritional spray, but care must be taken to mix these together just immediately before use.
