Risk Assessment for Fusarium Mycotoxins Close Window
Instructions
This site allows you to assess the risk of Fusarium mycotoxins in wheat, for single or multiple fields.
You will first be asked to enter your store name, farm name and town, county and postcode.
You will then be able to assess the risk of each field on your farm, using the "Assess" page (Fields can be grouped if grown with the same agronomy).
After you finish entering data for each field, you will be returned to the "Summary" page where you can see a list of all information that you have entered so far.
From the summary page, buttons are available to allow you to edit your farm details, add or edit field information, save the information to a file on your PC or print the information you have entered.
Assessment of Risk for Each Field
Each field must be assessed for each of the following risk factors:
|
Cultivation
|
Crop debris is an important source of fusarium. Complete burial by ploughing reduces risk to the greatest extent while risk is highest with direct drilling. Intensive non-inversion tillage (3 or more cultivations with discs, tines or chisel plough) is more effective at reducing risk than standard non-inversion tillage (1 or 2 cultivations). Note that several cultivations may be achieved in a single pass using appropriate machinery.

|
Wheat Variety
|
Enter according to HGCA Recommended List rating for fusarium ear blight. If score is not known, assume susceptible and allocate score of 1. click here for Winter Wheat Recommended List |
|
T3 Fungicide
|
Using an appropriate dose rate of a T3 ear fungicide recommended against fusarium and/or mycotoxin production reduces the risk. Current approved fungicides include products containing dimoxystrobin, metconazole, prothioconazole, epoxiconazole, tebuconazole or thiophanate methyl. |
|
Rainfall at flowering
|
Wet weather promotes fusarium development. The score is based on total rainfall during flowering (GS59-69 – full ear emergence to end of flowering)
|
|
Rainfall pre-harvest
|
Based on total rainfall from crop starting to ripen (GS87 – hard dough) to harvest.
|
|
Map of risk areas
|
The high risk area now includes all parts of Southern Welsh counties, Gloucestershire, Leicestershire, Derbyshire, Nottinghamshire, Warwickshire, Northamptonshire and Yorkshire. Please see the map below for a rating of risk by region.
|
Once you have assessed each factor, the overall score is then calculated automatically.
Final risk scores must be reported on the grain passport, and lots with scores greater than 15 should be tested and the result reported. Additionally, growers should check end-user requirement (e.g. for breakfast cereals) if for mycotoxin testing is required at lower risk score values.
When you print the risk assesment table the printout will record the date on which the assessment(s) was completed, you should then sign the hard copy as a record of your risk.
