PLAN YOUR PLANTINGS FOR GREATER PROFITS 

MAGNAGOLD. Abundant tonnage and quality. 
Ears. 8%” to 9” x 1.7” to 1.9”, 16 to 20 rowed, cylindrical, well 
filled. Impressively tee but surprisingly tender, sweet and well 
flavored. Kernels light golden, deep, tender. 
Yields. Number of ears slightly more than Golden Cross. Weight 
of ears 80% more. Stalks 7’ to 8’, no suckers. 
Remarks: This is the bigger and later sweet corn needed for 
many markets and by canners where seasons are long enough. It is 
more resistant to wilt, heat and drought than Golden Cross. Customer 
reports are enthusiastically favorable. Size, appearance and quality 
assure easy selling at profit making prices.

Sweet Corn Planting Suggestions 
Getting the most out of sweet corn depends considerably on 
choosing hybrids and timing plantings so as best to meet one’s par- 
ticular situation. For instance, home gardeners, roadside stand 
gardeners, and some — but not all — market gardeners should plant 
hybrids that will provide a continuous harvest from the earliest date 
possible to the very last of the season. For some markets, only the 
earliest possible corns. pay well; for others, the latest; and for some, 
there. are in-between periods when prices are usually highest. 
Another consideration is the kind of sweet corn one’s market pre- 
fers. In some cases the preference is for tenderness and sweetness 
regardless of size of ears but in others size of ear is more important. 
In general, the shorter the period between picking and eating or the 
more prosperous the consumers, the greater is the demand for quality 
and vice versa. 
Our series of hybrids, ripening at intervals and including top 
quality hybrids, extra large eared hybrids and heavy stalked hybrids, 
helps you plan to meet your particular situation. 
AIMING FOR THE EARLY MARKETS 
Early market prices usually are highest. To make the most of 
them, we suggest one or two small successive plantings of SPAN- 
CROSS, before weather conditions are quite safe. Select early ground. 
Use our treated seed. Do not plant too deeply. Then when conditions 
are safe, plant at one time, all the SPANCROSS you can pick and 
sell in a week and all the WASHINGTON or MARCROSS you can 
market in 4 days. This furnishes sweet corn for the first 2 or 3 weeks 
of the season. If it is wanted for a longer period, make a planting 
of Carmelcross or Old Hickory at the same time. If any of the first 
planting is lost, replant with any yellow sweet corn or other crops. 
One of these plantings on the market ahead of the crowd, will more 
than repay the labor and seed lost on several. 
TO PROVIDE A CONTINUOUS SUPPLY 
For a continuous supply, make at least one planting of SPAN- 
CROSS a few days before the safe date. Then, when it is safe, plant 
Weed, Insect and Disease Control 
WEED CONTROL IN SWEET CORN 
The latest advices from investigators on chemical and flame control of weeds in 
sweet corn may be summarized as, “Wait for more information or try them on 
very small scale, except possibly in a save-or-lose-all situation.’”’ Tests to date reveal- 
Salt form of 2.4-D safer than other materials. 
Some varieties severly damaged by applications harmless to others. Which and 
why not fully known. 
Application just before corn breaks ground seems best, most 
other weeds killed then. Can be applied when breaking thru and 
Injury very likely from then till 8” tall, also when tassel is forming in boot. 
between these stages but then controls broad leaved weeds only, not grasses. 
1 to 2 Ib. 2.4-D in salt form for pre-emergence applications but only 34 lbs. when 
8” tall seem best amounts. 4 
Apply in 10 to 20 gal. of water per acre under 40 to 50 Ib. pressure thru low 
pressure nozzles. Dusting is questionable. 
Ground should be covered completely but avoid throat of plant. 
Equipment must be very thoroly cleaned before using for other purposes. 
Flame weeding as now practiced, in sweet corn requires conditions favorable 
for cultivating and is more expensive, so hardly practicable. Pre-emergence flaming 
might be justified when conditions prevent effective use of mechanical weeder. 
After-emergence flaming effectively used only when corn is 5” or taller and weeds 
1”, Most grasses survive two or three flamings. Bottled gases as well as oil are 
used. Fuel cost ranged around 50c¢ per acre per application. = 
Better plan to use the old weeder and cultivator again this year. 
CORN BORER CONTROL IN SWEET CORN 
DDT and Ryanex have given best control of borer in recent tests but DDT has 
caused stunting and smaller ears, especially on light soils or in drought periods. 
Ryanex, rotenone or nicotine are recommended in that order. 
Spraying or dusting should begin as soon as the eggs start hatching. The county 
agricultural agent can give the dates, or the masses of overlapping pinhead like 
white eggs laid on the underside of corn or weed leaves may be watched. They turn 
yellow and just before hatching, a black spot appears on each egg. They hatch in 
5 to 10 days from laying. A second brood may appear 4 to 6 weeks later. 
Four applications at 5 day intervals are necessary. Use Ryanex, 40% strength 
or Rotenone 2% strength, 30 to 40 Ibs. per acre each application. Timeliness is 
important. 
The materials must be applied in the narrow spaces between the leaf sheaths and 
the stalks, first in the developing whorls, then in individual leaves and tillers and 
finally on all parts of the developing ears. Other parts do not need protection. 
These treatments will not control earworm. 
In the over wintering stage, many borers can be killed by feeding, making into 
silage, plowing under thoroly or burning all corn stalks, ears and cobs as far ahead 
rasses as well as 
for few days after.

AIMING FOR THE LATE MARKETS a 
If your late markets are extra good, make several plantings of 
whichever late hybrid you prefer up to 90 to 80 days before that last 
picking date. If delayed by weather or if planting after an early 
crop, use one of the earlier hybrids (except Spancross). They may — 
be planted up to 75 to 65 days prior to the last picking date. r

OTHER SUGGESTIONS . 
These hybrids have the vigor to make fine big crops but ties must _ 
have plant food and moisture. Fertilize liberally. Commercial ferti-— 
lizer plowed under is better than shallow applications. A later side p 
dressing of nitrate usually pays, especially after leaching rains. Use 
every means to conserve the winter and spring accumulation of mois- 
ture. Hybrid corns must have normal or greater spacing. If you 
stand is too thick, be sure to thin it. This is important. Tests show No
