Tirem 200 SC Insecticide - Calibrate your Spraying Equipment
Failure to Calibrate your spraying equipment WILL highly likely result in either turf DAMAGE or POOR results.
To understand what Calibration is, (and why dilution rates DO NOT work) read on.
Tirem 200 SC Insecticide - How to Calibrate
What is Tirem 200 SC Insecticide’s Mixing Ratio / Dilution rate… there isn’t one. That’s right that was not a typo.
Tirem is a product that requires a set amount of Tirem over a set area. There are no dilution rates, dilution rates do not work… because if 2 people (YOU and ‘John Smith’) were to use the same equipment and do the same dilution rate and John Smith walks twice as quick as YOU then John Smith is under-dosing by half compared to YOU…… or you are double-dosing compared to John Smith.
Therefore, you need to calibrate your equipment, to make sure YOU know what water volume YOU are using over a set area, once YOU know this you can then add the Tirem rate into the water volume that YOU use for the area. Unless YOU know how much water YOU will use over 100 m2 YOU can NEVER get a set amount of Tirem evenly over 100 m2, water is the only carrier you can use to achieve this, so calibration is a MUST.
Let us use Tirem’s 25 mL per 100 m2 rate as an example. 25 mL in a convenient amount of water per 100 m2 (minimum of 4 L of water per 100 m2). With Tirem you can choose any water volume from 4 L and above for 100 m2. Once you have established YOU spray a certain amount of water over a set area (100 m2), you can then add the 25 mL of Tirem into that volume and spray 25 mL of Tirem evenly over 100 m2. For example, if John Smith sprays at 6 L per 100 m2 then John Smith puts 25 mL in 6 L of water to spray 100 m2, if YOU spray at 7 L of water per 100 m2 then YOU put 25 mL in 7 L of water to spray 100 m2.
How to Calibrate Pedestrian Spray Equipment
Spraying straight water on a concrete area is always best. It shows you how even or uneven you are and shows you how little you need to cover an area well. Your aim should be to simply wet the concrete evenly, DO NOT flood it or make the water run/move, just evenly wet it.
Do a blank run with JUST WATER in the sprayer so you can get your walking speed and spray pattern right. Practice on a concrete driveway (or any concrete) with JUST WATER, measure out a concrete area of 10 m2 (yes that’s TEN square metres - i.e. 5 m x 2 m rectangle area or 3.17 m x 3.17 m square area) to calibrate and practice. This will show you how even or uneven you are actually spraying, once you think you are spraying evenly and correctly let the concrete dry, then spray the 10m2 again with water and time yourself with a stopwatch/iPhone.
For this Example, let’s say it took you ‘32’ seconds (we have made up 32 seconds – don’t use this figure to bypass calibrating your equipment), you then put your spray nozzle into a measuring container (i.e. measuring jug) and you turn it on for the same amount of time, in our example ‘32’ seconds, at the same pressure you just sprayed that 10 m2 of concrete evenly, be sure to maintain the same pressure as you did spraying the 10 m2 of concrete (i.e. maintain hand pumping for pressure with manual pressure units).
Let’s say (for our example) you measure 780 mL of water, so you have used;
780 mL over 10 m2.
Which is 7,800 mL over 100 m2.
Which is 7.8 L over 100 m2.
[Note: if you have more than one nozzle (i.e. 3 nozzle boom) either measure volume from all 3 nozzles or measure 1 nozzle and multiple by the amount of nozzles.]
So, using our Tirem rate of 25 mL, we would then put 25 mL of Tirem 200 SC Insecticide into 7.8 L of water and spray exactly like we just did on the concrete in terms of pressure, wanding pattern and walking speed and we will evenly spray 25 mL of Tirem 200 SC Insecticide over 100 m2.
This is an example, please DO NOT simply take this as a dilution rate of 25 mL in 7.8 L of water. To get a result you need to calibrate, if you don’t your weed control will be limited and or overdosing can lead to turf damage.
If your calibration figure of water is under the water amount allowed, in this case under 4L of water per 100 m2 for Tirem 200 SC Insecticide, then you need to start again and do it slower, for example if you measured a water volume of 350 mL per 10 m2 (which is 3.5 L per 100 m2) then you need to do it again slower, applying a little more water to get to at least 4 L (or higher) of water per 100 m2.
If an end-user reads the Tirem label and says, “right the dilution rate / mixing rate is 25 mL in 4 L of water per 100 m2 – because that’s what it says!”, and they go physically apply 12 L of water (dilution) per 100 m2 then they will have actually applied Tirem at 3 times the 25 mL per 100 m2 rate. This is when turf damage can occur. Furthermore, if they mix at a dilution rate they think is right based on Zero calibration they can also underdose which will lead to poor weed control.
If you are not getting a result or getting damage you are applying these products incorrectly. Turf Culture’s products require a ‘set amount of product’ over a ‘set area’ in a ‘specified amount of water’. YOU need to achieve and know the water volume within the specified amount of water by how you spray with YOUR spraying equipment. Water is your only carrier and vehicle to apply these products, without knowing the water volume YOU spray per 100 m2, YOU can never achieve a ‘product rate’ evenly over 100m2 (or your desired area).
