The interval between new active substances coming onto the market is long, and we see declining effects in those we already have. However, the effect of many pesticides can be improved with the addition of additives.


At BioNutria we have two types of additives: Ammonium sulphate, which increases the plant's ability to absorb glyphosate, MCPA and a few other pesticides, as well as Bio pH Control, which is used to regulate the spray fluid. 

Bio pH Control lowers the pH of the spraying liquid and neutralises the negative effects of calcium carbonate and magnesium carbonate.

BioNutria’s BioCrop series and BioMangan 170 NSP contain acidifying substances, but if you have very hard water, we recommend adding Bio pH Control.


When should you use a spreader-sticker?


A spreader-sticker should be used for spraying with a growth regulation agent and for most herbicides with leaf effect.

However, for herbicides formulated with OD, oil should be added if sprayed alone, and spreader-sticker should be added if it is in combination with other products where spreader-sticker is recommended.

All BioNutria products contain spreader-sticker, except for our products for organic farming and BioNutria Bor 150.

No oil should be mixed in spraying liquid containing manganese products or micronutrient mixtures.

When should you use pH regulating additives?


Always use Bio pH Control when using hard water in the spraying liquid. Primarily, by spraying glyphosate, pyrethroids, hormonal agents, MedaxTop and many beetroot products.

For example, Phenmedipham is halved in 7 minutes at pH 9, compared to 47 days at pH 5. Furthermore, it is a good idea to add a pH regulating additive when spraying BioNutria Bor 150.
