In recent years, agricultural machinery for precision agriculture has made extensive use of information and communication technologies. An Android-based module was developed in this study to allow the nozzles on field sprayer booms be opened closed as a group. The tested 24 m working width sprayer, controlling 48 pairs 4-8 groups based GPS position data. For control, an electronic control unit ...

Organophosphates and carbamates (OPs/CMs) are known for their acetylcholinesterase inhibiting character. A cross-sectional study of pesticide handling practices and self-perceived symptoms of acute pesticide poisoning was conducted using questionnaire-based interviews with 89 pesticide sprayers in Boeung Cheung Ek (BCE) Lake, Phnom Penh, Cambodia. The study showed that 50% of the pesticides use...

In the absence of End of Service Life Indicator (ESLI), a cartridge change schedule should be established for ensuring that cartridges are changed before their end of service life. Factors effecting service life of cartridges were evaluated, including the amount of atmospheric contamination with aromatic hydrocarbon vapors in the workplace, temperature, and relative humidity of the air. A new c...

ABSTRACT Growers have rapidly adopted auxin-resistant cotton and soybean technologies. In Georgia, growers who plant cotton/soybean are required to utilize nozzles that produce larger (coarser) droplets when spraying auxin herbicides minimize potential off-target movement of pesticides. Consequently, these also used in peanut (an important rotational crop with cotton) since changing between cro...
