Dusts should be applied at a rate of 20 to 35 lbs.
per acre and sprays at a rate of 75 to 150 gals.
per acre, depending on the size of plants.
Precautions.-Insecticides and their residues
are poisonous to man and animals. Do not spill
them on the body or inhale spray mist or dust.
Carefully read and follow precautions on the labels
Do not apply DDT, chlordane and toxaphene
later than 30 days, or parathion later than 15
days before first cutting. TEPP can be used 24
hours before cutting.
DISEASES AND CONTROLS
Downy Mildew and Alternaria Leaf Spot-Spergon wet-
table, 48% 4 lbs. per 100 gals. water. 12% Spergon
Begin applications 7 to 10 days after planting
m.nd repeat three times a week until plants are
set in the field.
Plants are susceptible to both diseases at all
stages of growth, but downy mildew is more com-
mon and destructive in the seedbed.
Total number of applications may vary from 6
to 15, depending upon the season and weather.
The amount of spray or dust varies also with
size of the plant. These materials are compatible
with TEPP, parathion, DDT and chlordane.
Downy Mildew and Alternaria Leaf Spot-Nabam (27%)
2 qts. plus % 1 Ib. zinc sulfate per 100 gals. water.
Where seed is sown directly in the field spray
seedlings two to three times a week, beginning
when seedlings have emerged and stopping when
plants are thinned to a stand. If Alternaria leaf
spot is developing rapidly when heads are half-
grown, resume spraying and using 100 to 150 gal-
lons spray per acre every four or five days.
Nabam is very effective against Alternaria leaf
spot in the field and gives good control of downy
mildew. Use 2 to 3 ounces of spreader-sticker
per 100 gallons.
(Nabam is compatible with TEPP, parathion,
DDT and toxaphene.)
Black Rot-Hot Water Treatment, 122"F. for 25 minutes.
Fill cheesecloth bags about two-thirds full of
seed, tie the tops and immerse in a container of
water at the temperature indicated. Keep the
water within 1 of that specified. Keep the seed
under water and stir to maintain uniform tem-
perature. At the end of the period remove seed
from the hot water and plunge into cold water-
spread out and dry. Treatment is a delicate oper-
ation and is best performed by a trained operator
using special equipment.
Test seed for germination before treating with
hot water. Weak seed may be killed while good
seed will stand treatment and germinate well if
planted the same season it is treated. Seed grown
in the Puget Sound area does not need treatment.
The disease organism is short-lived, but it is not
advisable to plant cabbage on land planted to
crucifers the previous year.
Black Leg.-Use same treatment as for black
Use seed grown in areas where black leg does
not usually occur, such as the Puget Sound area.
When in doubt of seed source-treat.
Yellows.-No control after soil is infected ex-
cept use of resistant varieties. Growers should
take every possible precaution to secure disease-

Production practices are subject to rapid change-
by new problems arising and the application of
research results to meet these needs. No attempt
is made here to foresee all the complications pos-
sible, but instead to present the current pertinent
facts on cabbage production. Experienced grow-
ers may have several modifications of these prac-
tices for their specific conditions.

On sandy soils apply fertilizer for seedbeds at
rate of 1,000 to 1,200 pounds per acre in bands
2 to 3 inches to the side of and 1 to 2 inches be-
low the level of the seed. Plants in seedbed may
be side-dressed once or twice with 50 to 75 pounds
nitrate of potash or nitrate of soda per acre.
Cabbage in fields can be fertilized before or
shortly after transplanting, using band place-
ment. Side-dressing two or more times with 150
to 200 pounds nitrate of soda or nitrate of potash
per acre may be necessary, depending on rainfall
and growth of the crop.
It has been a general recommendation in the
past that all of the fertilizer be broadcast on peat
and muck soils before seeding or transplanting.
Responses to the banding method of fertilizer
application have been noted recently on muck
and peat soils having high pH values.
Pounds per Acre
Minor Elements.-The following minor elements
may be needed on specific areas:
Copper as copper sulfate at 25 pounds an acre
on muck and peat soil; manganese as manganese
sulfate at 25 to 30 pounds on muck, peat, marl
and sandy soils having a pH of 6.0 or higher;
usually more satisfactory results are obtained
when applied as a spray, using 2 pounds MnSO4
to 100 gallons of water. Zinc as zinc sulfate and
boron as borax on muck and peat soils at rate of
10 to 12 pounds an acre.
Deficiency symptoms on certain sandy soils
have occasionally been observed but are not neces-
sarily corrected by use of boron when applied in
fertilizer or as a spray.
