Droplet size spectrum, velocity, angle and flow rate of pulse‐width‐modulated spray nozzles with adjuvants

open access: yesPest Management Science, EarlyView.
Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.

Insect and Mite Pests

2020
Insect and mite pests are a major constraint to greenhouse production of vegetables, fruits and ornamentals. As the abiotic conditions in greenhouses are relatively stable and uniform in most parts of the world, the insect and mite pest fauna is dominated by a relative small number of usually polyphagous species.
