Allman Hollow Cone Tips: Disc &
Core
Suitable for Overall Spraying of insecticides and
fungicides, particularly wettable powders and other erosive particles.
Swirl action keeps the particles in suspension, thus reducing nozzle
blockage.
The spry target should be the ear, or crop canopy, since their poor
crop penetration makes hollow cone tips unsuitable for deep herbicide
application or stem contact.
The disc and core combinations below have been selected for their
minimum 80° included angle |
