Crop enhancer produces ‘impressive’ results
increasing yields in cereals. Klorofill is a liquid formulation of pentanoate – an organic compound that contains a keto acid. Agrovista technical manager John Murrie says it is a vital precursor in chlorophyll manufacture within plants. “Chlorophyll is essential for pho- tosynthesis, so maintaining efficient production is key for healthy yields and profits,” says Mr Murrie. All crops stand to benefit, he adds.

“Klorofill can help high potential crops live up to their promise by op- timising yield, quality and return on investment – especially during rapid spring growth, when chlorophyll pro- duction can lag demand.” Pentanoate significantly increases the photosynthetic rate, says Mr Mur- rie. “Klorofill seems to build a bigger flag leaf and convert this into yield in many

cases. We’ve seen 0.4-0.5t/ha increas- es in wheat and barley crops on farm.” Derived from plant material,
Klorofill is supplied in a soluble and tank-mixable liquid formulation ap- plied at 1 litre/ha.
It can be partnered with fungicides, plant growth regulators, magnesium and other nutrients. On winter wheat and winter feed
barley, the product should be applied at T2 for maximum benefit, and on winter malting barley at T1. On spring bar- ley the optimum timing is GS30. It is not recommended on malting crops af- ter that time. Jim Anderson at Newton of Guthrie, near Arbroath, Angus, tried Klorofill after good results with Terrasorb, an amino acid-based biostimulant de- signed to aid establishment and re- lieve early crop stress. Mr Anderson treated 10ha of winter wheat and winter barley, both grown on medium loam soils, with 1 litre/ha

at T2, during what was a pretty dry season. Wheat yields rose by 0.35t/ha and barley yields by 0.6t/ha. “In the wheat, you could see to the
mark where we had applied it,” he says. “The flag leaf was bigger and greener and the whole crop looked healthier. I couldn’t see any difference in the [bar- ley] crop, but when the combine went in it was obvious.”
