Small amounts of boron enhance the uptake and performance of expensive macronutrients. Make your nutrient investments go further with Liquibor.

Time in the field

Liquibor puts you in control. Whether you spray directly on crops or add it to a tank mix, liquid boron saves time and optimizes in-field applications.

Friction-free fertilization

We specially designed Liquibor for easy, effortless incorporation into your existing foliar nutrition program. This liquid boron product upholds the performance of other crop nutrition and protection ingredients found in fertilizer formulations. 

Unblocked spraying

Liquibor's solubility prevents particles from blocking your spray nozzles, resulting in uniform distribution.
