Years of research, trials and practical experience has shown Primo Maxx is most effective during conditions most conducive to turf growth - especially in spring and early summer.

For initial Primo Maxx applications this spring, it is advisable to start the programme with a half-rate treatment, to gently move the turf plants into growth regulation mode. For follow up applications you can safely use the full rate and recommended treatment timings. It is always advocated to include an appropriate rate of liquid N in the Primo Maxx tank-mix to maintain turf health and vigour.

As a general rule, when growing conditions are good - warm, moist and bright - the frequency and rate of Primo Maxx application should be increased; if seasonal conditions are dry, cool or dull, however, the application frequency may be extended.
