The Crop Care Formulating Tool calculates a triangle blending schedule and evaluates results based on the specification of your defined ingredients.  Developed for three component blending, the tool is useful for all kinds of formulation development programmes, including EC, SC, EW and WG systems.  You can enter your results into the tool, and depending on the outcomes, the tool can advise you to continue with your current blending schedule or to start afresh. Your data can be continuously saved under your own personal username and password. You are therefore able to recall your data and continue, or re-evaluate your work, at any time.

How to use the Crop Care Formulating Tool

Go to the Crop Care extranet site and click on the Crop Care Formulating Tool link.

Step 1: Fill in the start page

On the start page, you will be asked to define the general formulation composition, ingredients information, and user account.

Formulation composition
Enter the active ingredient concentration and total surfactant concentration. 

Ingredients information
Enter the name of the active ingredient, concentration, assay and density. It is possible to use code names, in case you do not want to reveal the name of your active ingredient. You can enter a maximum of 6 active ingredients.

Enter the name of the solvent and its corresponding density.

Enter the names of the three surfactants with corresponding assay and density.

User account
Your data can be saved on our server. Click on ‘help’ for instructions on how to define your user account, password and experiment number.

Step 2: Calculate and evaluate experimental schedule

After completing the start page, click on the 'Show schedule' button and the tool will calculate a triangle blending schedule. A triangle blending diagram will appear at the top of the webpage, see figure below.


Every number represents a specific ingredient ratio. The numbers that are highlighted in light blue are the mixtures that should be formulated for testing. The recipe of these mixtures can be found in the table at the bottom of the webpage, see figure below.


After you have completed all blending tests (10 blends in this example), go to the ‘Results’ column and select whether your formulation meets your defined performance criteria. An example performance criterion is emulsion stability over 24 hr in 342Ca2+. The results tab is then filled in as either stable (pass) or not (fail). Then, click on the 'Evaluate result' button and the tool will evaluate your initial results. The next webpage will show a new triangle blending schedule depending on the outcomes of the previous tests. In this example, only two mixtures are rated as ‘Pass’.

Mixture numbers that are highlighted with red are unstable emulsions, and yellow are stable. The numbers highlighted in light blue are new formulations to be tested. The table at the bottom of the webpage contains the recipe of the new blends to be tested. 

Continue with your experiments until the tool does not advise any new tests. This can be seen from the triangle blending diagram after clicking on the ‘Evaluate results’ button. 

Using the tool when you are already in the test phase

After calculating an experimental schedule, you are able to leave the website if you want. Your experimental schedule will have been stored under your account and can be recalled. Go to the start page and click on the ‘Click here to continue’ link.

A new webpage will load asking you for your account and password. 

After entering your user details and clicking on the ‘Show history’ button, a table will appear containning all your experiments carried out from the last 6 months.


Clicking on the green arrow in the first column will retrieve your experimental results and you can continue depending whether the test has been finished.
