Good question. Yes, unlike conventional fungicides, chitosan is not directly biocidal. Instead it acts by activating plant defence mechanisms and producing a bioplastic barrier to spores. Chitosan has got a long history of use in brewing and in drug delivery. As such, it is safe to use just...

Many thanks for everybody's help with this one! If you are interested; I have collated most of the available info on pre-harvest indices and produced the tables below with a range of fungicides and their authorised PHI. The first table is for cereals, and the second one is for 'other crops'...

Oh bugger. Yeah. Even if I restrict it to just cereals I am still at 300. Luckily most of these fall into big groups with the same active ingredients though.

Hi Following on from this initial post, I have put together the table below listing all the fungicides I could find for sale in the UK and the pre-harvest index for them. Have I missed any fungicides that you routinely use on your particular crops? Regards Russell

I live in Northants and had a large glasshouse near Harborough for a while. My top tip is to cycle around the county looking for abandoned greenhouses or polytunnels and then ask the landowner if you can take them over, or add one next to them. The advantage is they have everything set up and...

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: https://www.eutrema.co.uk/product-page/chitosan I was...

Thanks Ken The product is not Halloween 🎃 based. Yes, happy to share details once it has launched. Russell

I’d put money on it that they haven’t 😂

Thanks Smith31. Appreciated.

Thanks An. I’m really just looking for help in sourcing the material, rather than critiques of various business ideas.

It's not a food/feed project.

PS - could be cow or sheep blood. Just needs to be blood basically.

Hi I was wondering if somebody on here could point me in the direction of an abattoir where there may be significant volumes of blood being collected? Preferably in the East Midlands. We have an idea for a blood-based organic product, but unlike the standard blood-based products, it would not be...

Hi All I have just published a blog post all about the BASIC SUBSTANCES. The BASIC SUBSTANCES are a group of 20 compounds that can be used in pest and disease control on UK farms. However, they aren't (to any wide degree). However, British farmers could be missing out, especially as many of...

Hi All I have just published a blog post on the above topic. I would to get the thoughts of end users on the content and the subject in general. I would be especially interested in perspective from farmers who have tried organic pesticides. The full blog post can be found here...

Many thanks. I think moles would depend on the type of soil. I guess they could act as fabulous natural ploughs in the right context. :) Plus they might be eating soil based pests, like leatherjackets and wireworms, or they could be eating friendly earthworms. I know greenskeepers are unusual...

Yellow jacket wasps is a great shout Midds!

Hi All I have just written this blog post about organisms that are sometimes mistaken for pests in crops. https://www.eutrema.co.uk/post/animals-often-mistake-for-pests-by-growers I would love to know this community's thoughts on it. Are there any creepy crawlies I have missed off that you...
