- The problem
to be solved:
Successful production of biologically valuable
seed on highly susceptible plants of maize.
|
- Definition:
Ripening accelerators and fungicides applied to
the foliage in combination enhance each other’s
effects and “cure” seed which has started to
rot.
|
- Presentation:
The
doses given in the table should be applied on a
single occasion as required if the degree of
internal infection of the seed with fusarium is
over 20 % and the kernel moisture content is less
than 60 % for sweetcorn and less than 45 % for
fieldcorn.

of stand treatment on the quantity and quality of
seed produced

Treated1
= 2 l/ha ripening accelerator (active agent: 22.4
% dimethypin) applied in combination with 2 kg/ha
fungicide (active agent: 50 % benomyl)
Treated2 = 2 l/ha ripening accelerator
(active agent: 22.4 % dimethypin) applied in
combination with 1.5 kg/ha fungicide (active
agents: 50 % carboxin + 15 % copper
oxyquinolate).

- Advantages:
- No
significant yield losses due to the
discarding of infected seed.
- Less drying
energy, lower drying costs.
- Larger
quantities of seed can be dried in unit
time.

- Stage of
development: Technique suitable for
direct application
