Falcon
rate is dependent on size and conditions at time of application.
Use mainly for volunteers (0.25-0.5lt/ha). Reasonable on Brome.
One of the weaker ones on tough/resistant blackgrass.
Aramo is good on volunteers, Brome and effective in both target
site and enhanced metabolism resistant situations although like
Laser, we have seen problems. Apply no later than 9 leaves or
end of November.
Laser is good on volunteers, Brome and non-resistant blackgrass
but can get problems in resistant situations.
Residual
Herbicides for control grass weeds.
One

Only
use Folicur on good vigorous crops. Do not apply to backward
or stressed crops.
On light land it is likely an application of Boron will be beneficial.
Use Bortrac 150 at 3lts/ha.
Caramba can be used at this stage instead of Folicur at 0.6-0.8lt/ha.
This may be a little more aggressive on the crop but is probably
the stronger of the two with regards to regulatory effect..
Adjuvant
can be justified because of the difficulty of getting droplets
to stick to rape.
Adjuvant choice @200lt/ha
1. LI 700 at 1.0lt/ha
2. Crop oil.
Green
Bud/Pollen Beetle
Use
an approved pyrethroid. Some of the choices are.
