The Mankar we have gets used nearly every day on our Estate and it’s a super tool in our weed prevention programme. It’s good for accurate general spraying but we like the Mankar for spraying around the base of our Christmas trees.
The Mankar gives a good accurate spray of Glyphosate 100% of the time without having to trudge back and forth to refill it with water.

All this results in more pesticide than necessary having to be used to compensate for the inefficiencies of this method of spraying.
Also the fetching and carrying of the extra pesticides and the water to dilute it is both labour intensive and costly.
The CDA system uses the centrifugal force created by a spinning disc that throws the spray away from the machine in a hollow cone type pattern. The disc speed can be altered thereby altering the size of the droplets, the faster the speed the smaller the droplets. This is especially useful when adapting the spray to suit the targeted pest, with smaller droplet sizes for insects and the larger ones for weeds.
The droplets created are more uniformly sized, therefore reducing the chance of drift and ensuring a more even spray pattern. This allows less chemical to be used with the resulting savings in both chemical and labour.
For instance an average application of glyphosate with a conventional sprayer is 5L in 200L of water per hectare.
A CDA formulated Glyphosate such as ‘Vanquish’ is applied at 15L per hectare without the need to use water.
The controls on the lance can be set to the amount of chemical required in regards to the operators walking pace, ensuring that the right amount of chemical, (L/ha) is applied.
In short it’s a spraying system that is quick and easy for the user to calibrate and use.
The nozzles high speed creates droplets that are ejected from the nozzle at very high speed and with a very small droplet size, (150 Microns). These droplets are dispersed tightly over a small area maximising the chance of even the smallest weed being hit with a droplet of chemical, making it a more effective method.
Due to fineness of the spray droplets, (with the exception of misting systems), most ULV systems are shrouded to prevent any drift. Whilst these can limit the width of spray, it also means that the operator can use this type of machine in far higher winds than you can with either conventional or CDA applications.
The fineness and closeness of these droplets mean that the chemicals can be applied in both an undiluted state and at much lower rates of application.
A ULV machine using Roundup Pro Biactive 450 can apply it at 2L/hectare rather than the 4L/hectare plus water in a conventional sprayer.
When an operator is faced with a large area to spray, the resulting savings in both time and materials can potentially be huge.
