J.F.L. Childs, Ph.D., U.S.D.A., Retired, was the Study Director for
the various citrus research summarized herein. Research was published
in the Proc. Florida State Horticulture Society 94. Article was titled,
"Control of Citrus Blight Disease."
CITRUS DECLINE SYMPTOMS
The term "Decline" includes a number of other names such as young tree
decline, citrus blight, sand hill decline and rough lemon decline. In
the order of their development the general symptoms associated with
decline are: dehydration, delayed leaf flushes and blooming, deficiency
symptoms (especially zinc), defoliation, twig and branch die-back (usually
accompanied by vigorous sprout growth from the trunk and lower branches),
fruit production declines during the entire decline development period,
and the tree dies.
CITRUS DECLINE - CURE THEORY
The necessary unidentified essential trace elements are contained
in AZOMITE™. Good soil management practices,
plus treatment of the soil under the drip line with AZOMITE™ will avoid and reverse the effects of citrus decline.

VALENCIA ORANGE TREES ON ROUGH LEMON ROOTSTOCK
Researcher reports all treated trees had an annual application of 1.8
to 2.2 kg of AZOMITE™ for a four-year period.

Research reported that the owner pulled all trees that appeared decline-affected,
including about 135 AZOMITE™ treated trees
that the researcher believed had started to recover. Even from the owner's
perspective there was a 22% decline decrease in the AZOMITE™ treated trees compared to a 76% decline increase in the check trees.
MURCOTT ORANGE TREES ON ROUGH LEMON ROOTSTOCK
Researcher reports that this small study was designed to test the effects
of heavier treatments of AZOMITE™. Decline
trees received 6.8 kg of AZOMITE™ spread by hand within the drip line and raked in by hand. Healthy trees
received 4.5 kg of AZOMITE™ applied in the same manner.

Researcher reported all healthy trees remained healthy and 22 of the
25 decline-affected trees showed almost complete recovery.
Valencia Orange trees in decline were recovered and became healthier
with increased productivity with 2 kg/tree/year of AZOMITE™ in 4 years.
Murcott Orange trees in decline were recovered in 1 year with 7 kg/tree.
