An orchard variable-rate sprayer applies the appropriate amount of plant protection products
only where they are needed based on detection data from advanced sensors, a system that …

The pulse width modulation (PWM) spray system is the most advanced technology to obtain
variable rate spray application without varying the operative sprayer parameters (eg spray …

In order to evaluate economic and ecological benefits, site-specific weed control was
realised in a 4-year experiment on five fields with a GPS-guided sprayer. An average of 54 …

BACKGROUND Pesticide applications using a specific droplet size and carrier volume could
maximize herbicide efficacy while mitigating particle drift in a precise and efficient manner …

A smart sprayer comprises a detection system and a chemical spraying system. In this study,
the development status and challenges of the detection systems of smart sprayers are …

The smart sprayer, a local-vision-sensor-based precision chemical application system, was
developed and tested. The long-term objectives of this project were to develop new …

Precision modulation of nozzle flow rates is a critical step for variable-rate spray applications
in orchards and ornamental nurseries. An automatic flow rate control system activated with …

Remote sensing using unmanned aerial vehicles (UAVs) for weed detection is a valuable
asset in agriculture and is vastly used for site-specific weed control. Alongside site-specific …

Chemical weed control remains a widely used component of integrated weed management
strategies because of its cost-effectiveness and rapid removal of crop pests. Additionally …

For effective operation of a selective sprayer with realtime local weed sensing, herbicides
must be deliveredaccurately to weed targets in the field. With a machine visionbased …
