Seed Treatment. To minimize the occurrence of bacterial canker,
bacterial spot, and bacterial speck, seed should be treated
with chlorine. If seed is not treated with chlorine by the
seed company, then dip seed in a solution containing 1 quart of
household bleach and 4 quarts of water plus one-half teaspoon of
surfactant for 1 minute. Provide constant agitation. Use 1 gallon
of solution per pound of seed. Prepare a fresh solution for each
batch of seed. Wash seed in running water for 5 minutes and dry
seed thoroughly. The final rinse should be done with acidified
water (1 oz. vinegar per gallon of water). Further information on
seed treatments can be found under SEED TREATMENTS in
the disease management section of the handbook.

Hardening Transplants. It is usually desirable to harden
tender tomato seedlings before planting them in the field. Recent
research has shown that hardening tomato plants by exposure to
cool temperatures (60° to 65°F/day and 50°to 60°F/night) for a
week or more causes catfacing. Harden plants by withholding
water. Allow plants to wilt slightly between light waterings. Do
not harden transplants by withholding fertilizer.
Drip Fertilization. Fertigation should be based on a soil test,
adjust soil pH to 6.5 and, in the absence of a soil test, apply
enough fertilizer to supply 50 pounds per acre of N, P2
K2O, (some soils will require 100 pounds per acre of K2
O5
thoroughly incorporate into the soil.
After mulching and installing the drip irrigation system, the
soluble fertilizer program should be initiated according to the
following table. On soils testing low to low-medium boron, also
include 0.5 pound per acre of actual boron.
The first soluble fertilizer application should be applied
through the drip irrigation system within a week after field-transplanting
the tomatoes. Continue fertigating until the last harvest.
