Frequently Asked Questions

Q. How far does a box of herbicide go?

A. This is dependant on product, weed type, application rate etc. Always read the label.

Q. How long can you spray a Superpro Plus for from one full battery charge?

A. full day's spraying?

Q. What happens if someone's dog/cat licks the white spots off the weeds?

A. Nothing. All products have a MAPP number that ensures all Nomix TDC products are approved for use in situations where domestic animals are present.

Q. What happens if I don't clean the lance after spraying?

A. It blocks up. Always ensure Nomix TDC lances are cleaned with Nomix Cleaner after spraying to avoid delays in your spray program.

Q. How often do I need to clean the lance?

A. At the end of every day's use.

Q. Do I need to clean the lance when I stop for my lunch?

A. Not if you go straight back to spraying.

Q Why are you all dressed up in your PPE when you say it is a safe product and will not harm me or my child?

A: I am wearing it to protect my clothing and because I am continually using the chemical unlike a pedestrian who could possibly have only miniscule contact.

Q. How deep must we bury Japanese Knotweed contaminated soils?

A. At least 5 metres deep & 7 metres from the margins of the site

Q. How much Glyphosate do I put in my 15litre knapsack?

A: This depends on the pressure of the knapsack, the jet being used, the application rate and the speed of your walking. Calibration is/was part of the PA6 A and should be carried out prior to every application.

Q. Can I apply Casoron G to newly planted shrub areas?

A. No. Ornamental plants must have been established for at least two years before applying Casoron G. The only residual herbicide which can be applied to newly planted shrub bed areas is Premiere Granules.

Q. Is there a residual herbicide which can be applied to bedding areas, as I have a real problem with chickweed?

A. No. Any residual herbicide (even Premiere Granules, which can be applied to newly planted shrub areas) would effect the shallow rooted bedding plants. Best advice is to remove old bedding plants, leave for a week, then treat any weed with glyphosate at 5 litres/ha before re-planting a week later. However, this will only kill what is present at time of spraying. A more permanent, but rather drastic approach, would be to completely remove the soil and replace with fresh; or to leave the bed fallow for a season and treat weeds as and when they occur.

Q. I have been treating the area around my 18-month old saplings with Hilite since planting. Can I now use anything more effective?

A. Yes. As the roots will have gone sufficiently far down, then I would use Touche at 15 litres/ha for effective residual weed control.

Q. When is the best time to apply Garlon 4 for Japanese Knotweed control?

A. As Garlon 4 is an auxin mimic, it is best to apply when the plant is actively growing and when the leaves are fully unfurled, thereby maximising herbicide uptake. In trials conducted by Nomix Enviro, the addition of Mixture B (a 2% final solution) has given excellent control, with Garlon 4 applied at 6 litres/ha. In fact, late season application with Garlon 4 gave poor results; which contrasts with glyphosate, which works better just before the onset of natural senescence. If the Knotweed is too tall when first visiting the site, you can either carefully treat the leaves using an extended lance; or cut the stems down, leave them on site and re-teat when approx. 1.5m tall and when the newly emerged leaves have fully unfurled.

Q. What is the best control for Laurel suckers?

A. When I treated some suckers for a customer, I used Garlon 4 at 10 litres/ha, Mixture B (used to help penetrate the thick waxy cuticle) and Nomix Blue dye (to see where I had treated, as treated leaves dry blue. Without this, it is very difficult to see what has been treated, as the leaves dry clear). An interesting comment is that when using the dye in this mixture, there is no smell at all, which could be useful if spraying in sensitive areas.

Q. Can I spray Japanese Knotweed with Tordon 22K at 11.2 litres/ha, as i have heard that this gives excellent control?

A. Unless there is bramble and or bracken present, then this rate should not be used. The recommended rate for Japanese Knotweed was 5.6 litres/ha applied to the foliage. However, Dow AgroSciences (the manufacturer of Tordon 22K) have changed the label: now, it is possible to spray on multiple occasions, AS LONG as the maximun ANNUAL rate of 11.2 litres/ha is not exceeded. And this is for the foliage. So you could apply 5.6 litres/ha twice per annum, 3.73 litres/ha three times per year and so on. If you have evidence of bracken on site as well, however, then you can apply Tordon 22K at the maximum rate of 11.2 litres/ha as a pre-emergence (i.e to the soil).
