Mixing
We recommend adding at least 20% water to all formulations. Some products, as marked in the list, require 40% to 70% water to be added to ensure adequate mixing.
The correct order of mixing is as follows:
Agitation
Some of the chemicals used will separate from the liquid fertilizer if agitation is not adequate. Summit recommends that at least 300 litres per minute of bypass flow is used. Alternatively, a separate agitation pump should be fitted.
It is not recommended that the mix be left in tanks for extended periods with no agitation. Summit recommend the tank is emptied of all chemical before leaving. If this is not possible, thorough agitation before restarting is required, checking that adequate mixing has occurred.
Compatibility
The term ‘compatibility’ in this context refers to the ability of the chemical to physically mix with liquid fertilizer and be used through standard boom spray equipment. It does not mean that the efficacy of the chemical is not degraded.
There are many factors that may affect compatibility, including water temperature, pH, water hardness and impurities. At Summit, we have tested a wide range of active ingredients for compatibility, however, we have not tested every possible formulation.
If planning to use a formulation or brand that is not listed, make sure a suitable jar test is performed before committing to use that chemical with a liquid fertilizer. Similarly, if attempting to use a mix of chemicals, a jar test is strongly recommended.
Scorch
Scorch can occur when liquid fertilizers are used. Recovery from scorch is usually rapid (about 1 week). Factors that can influence the amount of scorch include: the addition of oils, product formulation, moisture on leaves, rainfall, temperature, rate of product and dilution, growth stage and growing conditions.
Please note:
All formulations should be used with 20% water.
