International Spray-Jets low drift nozzles
are rated at 3 bar pressure with an angle of 80°
(top line below) or 110° (second line below) , these nozzles produce coarser droplets with a narrow elliptical spray pattern.
Features
Sizes 015, 02, 03, 04, 05 Low drift nozzles help lessen environmental impact by reducing the percentage volume of driftable droplets, minimising spray contamination off-target. Precision moulded in polyacetal, a highly stable material with excellent wear characteristics High level of quality control throughout the manufacturing process ensures consistent compliance with specification Colour coded (in accordance with ISO/DIS 10625) for quick identification of flow rate Compatible with most standard nozzle caps BCPC (British Crop Protection Council) coded to assist with correct nozzle selection Unique key supplied for removal of pre-orifice to assist cleaning
Applications
The Low Drift nozzles are used for broadcast application of pre and post emergent herbicides, fungicides, insecticides, growth regulators and
liquid fertilisers.
Spray Drift
Spray drift comprises small, wind borne droplets of pesticide carried away from the intended target area and into the environment. Research has shown that up to 20% of pesticides being released is contained in droplets less than 100µm in diameter. These are drift prone droplets capable of travelling great distances taking the benefits of the pesticide away from the target, to contaminate the environment.
Installation
To ensure uniform target coverage the boom height must be correctly adjusted in relation to the target and for the nozzle spacing used on the boom. The figures below provide a 50% overlap ensuring an overall even distribution. Ideally the nozzles should be offset by about 5° to the boom to minimise interference between spray patterns and to avoid droplets coalescing between the nozzle and the target. Most standard nozzle holders offset the spray by 5°
