Compatibility jar test
Before making a sprayer-full of tank-mix for the first time, it is advisable to check the compatibility of the components, unless it is a recognised mix shown on the label. This can be done conveniently on a small scale using a medium size screw-top jar.
Instructions

Use water at the same temperature as the spray supply (preferably use the same water).
Take a 2 L jug or sealable jar
Add 500 mL water
Add flowable, granular or powdered products and mix.
Add emulsifiable concentrate (ester or oil soluble) products and mix.
Add water soluble products and mix.
Add another 25 mL and mix.
Add other adjuvants and trace elements etc. and mix.
Add wetting agents and mix.
Add spray oils and mix.
Add water to make up to 1L and mix.
Leave the mixture to stand for several hours and note any separation or layering. Any settling of flowable or powder products is normal, but any difficulty in resuspending any sediment should be noted.

Kod nas je to test kompatibilnosti komponenti, preparata ili proizvoda (u zavisnosti šta se ispituje):

Prilikom mešanja preparata voditi racuna o njihovoj kompatibilnosti (pre primene izvršiti proveru, test kompatibilnosti preparata koje primenjujete) kako ne bi došlo do pojave toksicnosti na gajenim kulturama.
