DN-269 
For those who prefer a dust to a spray, DN-269 should answer the need for an 
efficient dust. It has proven to be an adequate control for the red spider mite on 
dahlias at the Ohio Experiment Station. I+ is a dust which is purchased ready to use. 
It is less likely to cause injury to foliage. It may be slightly less effective than the 
spray but, if necessary, an extra application will probably give control comparable to 
the spray. Both Dowspray-|7 and DN-269 are based on the same active ingredients 
and the same factors will apply to both. It is interesting to note that Dr. Neiswander 
controlled all dahlia insects with regular periodical application of a DDT dust and two 
applications of DN-269. 
NNOR 
NNOR is a product which has been on the market for a few years. It is a very 
good control for red spider and less toxic to foliage. This material is a liquid which 
is used as a spray according to manufacturer's directions. Those who find they can 
not use Dowspray-!7 would do well to try it. NNOR is compatable with DDT and 
can be applied in the same spray. 
OTHER METHODS 
_ There are numerous other preparations and methods for the control of red spider. 
We feel sure that one of them should sufficiently answer your particular needs. How- 
ever, we suggest that you consult your County Agricultural Agent or your state 
Experiment Station for their recommendation, or for their opinion of any product you 
plan to use. All insecticide manufacturers are working feverishly to produce the answer 
to the newly important red spider infestations. 
ROCKY RIVER INTRODUCTION 
WINDLASSIE ID (Rocky River) One of the 
whitest white dahlias we know. Petals 
are overlaid with a glistening sheen. 
When fully developed, this is one of 
the most ball-shaped flowers in this 
list. It will probably be classed as a 
'B' flower and as such is almost alone 
in the white informal class. Grown to 
its maximum of nine and a half to ten 
inches it has beaten the ‘argest white 
informals now being shown. Flowers 
cut when they are apparently “prime” 
continue to grow in water and the back 
petals close in tightly around the stem. 
In spite of its ball-shape it does not 
bruise easily when packed to take to 
show. It is an open grower. 
WINDLASSIE scored Certificates of 
Merit at Storrs and Baltimore and was 
on all Honor Rolls. 
Root $15.00, Plant $7.50
