Abstract:
The global trend to shift from highly toxic pesticides to environmentally safe and lees toxic chemical requires, generally, very high spatial uniformity of the spray deposition. Effective of the spray. A new sprayer was designed to achieve a sharp decline in air velocity to meet the two - seemingly contradictory - constraints, and thereby obtain effective penetration and coverage of dense canopy. In the present work, air ducts with several shapes of air outlets were developed and tested in an attempt to meet these requirements. Generally, a short and wide air slit created a moderate decline in air velocity; a longer and narrower; air slit improved the uniformity of the air velocity along the slit outlet, and brought about a sharper decline in speed of the air-streams. Installing air deflectors at the air outlets added a slight upward motion to the air-streams and enhanced spary deposition on the underside of leaves. Preliminary field tests with the long and narrow air slit showed uniform spray deposition on all plant parts.
