NEW PRODUCT INTRODUCTION
Anuew Growth Regulator
4 X 1.5 lb Box
Introducing Anuew™, a proprietary tool for cool-season turf management. Anuew contains prohexadione calcium, a new active ingredient with a novel mode of action that can be applied to all managed turf areas including golf greens, tees, fairways and roughs, residential and commercial lawns, sod farms, sport fields and similar areas.
FREQUENTLY ASKED QUESTIONS
Will this be a good alternative for annual bluegrass
greens in the northwest?
Yes, this is a good alternative in the northwest for annual
and perennial bluegrass/bentgrass mixed greens. Anuew
will gradually reduce annual cultivar Poa annua at higher
rates (above 8 oz/A).
The label recommends treatment every 1-2 weeks.
A) How does the product break down?
B) Should application intervals be based on
growing degree days?
The rates and application timing/frequency will vary based
on turf species and growing conditions. For example, use
rates for Poa will be lower at shorter intervals (2-4 oz/A at 1
week) and higher at longer intervals (4-8 oz/A at 2-3 weeks).
A) In soil, Anuew breaks down by oxidative mineralization
to carbon dioxide. Inside the plant, it goes through a
different conversion – it transforms into a free acid. Over the
next two weeks the free acid will rapidly deplete into many
low level metabolic forms.
B) Anuew is a late stage GA inhibitor in the
Acylcyclohexanedione group; therefore growing degree
days should be used to estimate plant activity and usage
rates. This is similar to methods used for trinexapac-ethyl
based products.
The brochure says to avoid mixing with calcium or
boron. Are there any other mixtures to avoid?
No, during product development no other precautions were identified. Is yellowing or bronzing to be expected after application? Should iron or nitrogen be added
to mask it?
With the exception of the annual cultivar Poa annua, there
were no reports of discoloration on any labeled turfgrass.
It’s important to note that the chlorosis effect (or discoloration)
on Poa annua only occurred at high use rates (above 8 oz/A)
and increased with each additional application.
How long does it take to notice growth regulation
after application?
Noticeable changes will vary by turf species due to
differences in absorption and translocation. In bentgrass/
Poa turf mixtures, reductions in clipping weight typically
occurred within 5-7 days after treatment.
Will the growth regulator improve turf quality and
stress tolerance?
Yes, numerous studies have shown changes in plant
physiology which could be considered an improvement in
plant quality and stress tolerance. Some of the documented
improvements include carbohydrate sequestering to crown
and roots, increased chlorophyll contents in leaves and
reduction in evapotranspiration.
