GM
Sugarbeet
Herbicide
Tolerance
 This sugar
beet works similarly to other such crops. It contains a gene that provides
resistance to one of two broad spectrum, environmentally benign herbicides.
Benefits
of HT sugar beets
| Limitations
on the spraying number |
Around
2 to 3 sprayings are required after plant emergence |
| More
freedom in the spraying time |
Selective
herbicide effectiveness is conditioned as a rule by rigorously
meeting the spraying guidelines as well as by weather conditions
and the phenological phase of both weeds and beet seedlings |
| First
spraying can be delayed |
Spraying
can be done 5-6 weeks after planting |
| Comprehensive
weed killing |
Using
broad-spectrum herbicides like Roundup or Liberty, even perennial
weeds are eliminated |
| Professional
advisory services are not necessary |
Only
one herbicide is applied in the dose recommended by the producer
and not a combination of doses of several types of selective herbicides |
| No
repression of seedling growth is observed as a rule |
Overdosing
with selective herbicides cause inhibition of beet seedling growth
and/or transient yellowing of leaves, which may result in decreased
root yield |
| Effective
control of secondary weeds |
If
need be, the herbicides can be applied until the interrow close-up,
resulting in an increased yield and in a lower dirt tare of roots
delivered to the sugar-processing plant |
| Less
hazard to the environment |
Both
glyphosate and glufosinate have lower toxicity and faster complete
degradation in the soil |
| Lower
costs of chemical weed control |
Systems
using Roundup Ready and Liberty Link herbicides have reduced their
weed control expenses by half compared with the costs of traditional
herbicides |
