Title: Water to low biuret urea ratio, for foliar spray?
Post by: Desertcitrus on January 13, 2021, 02:05:43 PM

I bought a low biuret urea and no instructions came with it. I looked on their website and could not find anything either. Can someone please tell me what the ratio for mixing would be.

Winter prebloom foliar spray application of low Biuret urea is known to greatly increase flower number, thus greater crop yield.  Proper timing is important to achieve the desired outcome.  Winter prebloom sprays are designed to increase flower number and fruit yield without reducing fruit size. Winter prebloom foliar sprays with low biuret urea (46-0-0 <0.5% biuret) is applied at the rate of .44-lbs. (200-grams) in 2 gallon of water plus one teaspoon of a good surfactant per gallon.. For large area sprays (acres) 50-lbs. per 225 gallons water. NOTE: a second low biuret urea foliar spray should also be done after early fruit drop and June drop periods to insure an  increase in fruit size.  In most areas  this would be around July 1 to July

Don’t many citrus naturally thin out their crops by dropping small fruits a little while after flower anyway..?

850FL, yes they do, but the more flowers, even with early drop, results in more fruit.
