Hi All
I am researching the potential for using one of our novel organic bio-fungicides in conventional cereal crops.
The product in question is chitosan, which can be used in the UK/EU for fungal disease control. For more details see:
I was hoping that somebody on here could answer the following question for me:
When is the last timing for a fungicide spray in a conventional wheat crop (growth stage/date of year)? And (most crucially), is the timing of that last spray determined due to experience of the efficacy of the sprays and the resulting impact on yield & quality, or because the product is only authorised for use with a pre-harvest index (PHI) for that time before harvest?
This is of importance to my research as, if the last timing is based on PHI, it could be that chitosan could be used by farmers (conventional and organic) looking for disease control later in the crop's development. Especially if other fungicides are not available during this time.
Even if the timing of the last spray is not based on PHI, I still think the product has good opportunities in this market as the dose cost for cereal crops is as low as £7/ha. So the successes we are seeing on strawberry/potatoes should still show good ROI in cereals.
I appreciate any help you can give on this matter, and I am happy to clear up any aspect that might not be clear.
Regards

Chitosan | Eutrema
BIOFUNGICIDE Chitosan is a natural carbohydrate polymer. As well as being used as a biostimulant, it can also be used as an organic biofungicide. This is because chitosan is listed as a ‘Basic Substance’ by the EU (regulations 563/2014) . Chitosan can be used by both conventional and organic...
