But, the Symphony nozzle control system allows the
sprayer to maintain constant pressure even when
changing rates or speed.
“When spraying to kill weeds or diseases, it is
important to get consistent spray patterns across
the field, even when changing speeds or rates,” said
Luke Stuber, Symphony product manager, Precision
Planting. “Symphony maintains consistent pressure
across the boom, along with swath control and turn
compensation for consistent spray coverage across
every acre of the field.”
Controlled by the Precision Planting
Gen3 20|20
system, Symphony will be field tested again in the
spring of 2022, along with its upcoming vision-based
technologies that it is developing for cameras on a
sprayer:
•
Vision-Based Guidance
: Post spraying crops
is a high-fatigue job on the farm, often with the
operator hand-driving the sprayer to keep from
running over crops. Vision guidance steers the
sprayer in the crop rows, allowing the operator to
focus on sprayer operations and not on steering,
all while preventing crops from being run over and
damaged, while providing a reduction in operator
fatigue.
•
Vision Scouting:
One of the best times to check
for even crop emergence and stand counts is
when most farmers make a post-emergence spray
pass. Vision-based scouting will provide farmers
with a snapshot of their stand count in the field
and information about how evenly the crops
emerged, letting them know if there are areas of
the field to which they should pay more attention.
•
Vision-based Weed ID:
Uses machine learning
and artificial intelligence to see and categorize
each plant seen in the field as a either a crop,
a broadleaf weed, or a grass weed. With this
information secured, a map of weed pressure
can be created that allows farmers to understand
the type of weeds and the variability in pressure
across the field.
•
Targeted spraying technology:
Precision
Planting’s Symphony Nozzle control system is
being designed to pair with the Precision Planting
vision module for targeted spraying.
“The combination of vision and Symphony will allow
spray rates to be varied within the label rate to be
effective against the weed pressure in a specific
area,” said Jason Stoller, Vision product manager,
Precision Planting. “We know that a high percentage of
sprayer passes use a residual herbicide, so targeting
only growing weeds does not allow for the value of
the residual herbicide to be present in the field. We
are actively researching the best way to spot spray
growing weeds while at the same time laying down a
blanket residual herbicide in order to control emerging
weeds, all using the 20|20, Symphony and Vision
technologies.”
