Directions For Use

Bontera® Bio-Assist is supplied in a water-soluble powder concentrate for extended shelf-life and ease of handling. One hundred grams of the powder concentrate is equal to 1 Litre of liquid concentrate. Dosage below per litre is based on the amount of liquid concentrate required.



1-3 applications of 0.1 - 0.4 L/ha at appropriate growth stages depending on plant/crop growth cycle. Use drip irrigation or other irrigation systems to ensure the product is well dispersed over the entire area.


Spray a 1:2,000 dilution of the liquid concentrate until foliage is completely wet at (1) new leaf emergence; (2) flower bud initiation; (3) re-growth; and (4) any growth stage thereafter that is considered important depending on the plant/crop growth cycle. Be sure to apply between 0.1 - 0.4 L of the liquid concentrate per hectare.
