✦ Synopsis

Airborne remote-sensing has been identi"ed worldwide as a promising technique for identifying and mapping weeds in crops, and potentially o!ers a solution to the current logjam in precision weed management: namely, the ability to generate timely and accurate weed maps. One of the main advantages of remote-sensing is that synoptic weed data can be acquired virtually instantaneously (within the "eld of view of the sensor), and a weed map generated within hours of data acquisition. However, because little information is available concerning the scale at which weeds should be managed within "elds, the sensing and mapping technology has tended to dictate the resolution at which weeds must be mapped. This paper summarizes the work completed to date to investigate the use of airborne remote-sensing for weed mapping in crops, and discusses application of the technology in precision weed management practices.

Axial fans with a radial air #ow have been most commonly used in fruit growing areas. These generate a large radial plume which is poorly targeted for modern intensive orchards. A high-volume directed air-jet system (HVDAS) sprayer, based on a standard axial fan has been developed to determine the i
