- If your spuds are suffering from potato leaf roll virus (which is becoming more of a problem apparently) dig up the affected plants and tuber immediately and dispose of.
- Sterilise water butts as they harbour all sorts of nasties, particularly in warm weather. Use a dash of Jeyes Fluid, Armillatox or cheap bleach which is just as good.
- If saving your own seed sterilise it with a powdered fungicide.
- Fungicides containing Pencanazole are a good general fungicide, which works on leek rust also.
- Dip brassica roots in a hydrated lime solution prior to planting to ward off clubroot.
- Perlka is another product for the control of clubroot.
- Leek and onion thrips are totally different to flower thrips. An insecticide from the garden centre advertising that it kills thrips will probably be the wrong sort therefore. Use a product called Dynamec and apply with a high pressure spray jet.
- Blight.....forget Dithane as most blights are immune to it. Bordeaux Mixture is about the best product available to the amateur grower.
- Do not use Growmore for potatoes as it is often bulked out with lime.
- Vitax Q4 is the best feed for spuds.
- Most of the above mentioned products are not on general sale. Seek out agricultural suppliers such as CWG in Melton Mowbray.
I have been growing and showing veg since 1996, a brilliant hobby contrary to popular belief and the views of my mates who think I’m a big poof (I’ve got nothing against poofs however!). This is just a chart of my progress for the 2017 season, if you have any specific questions about ‘showing’ then email me on smithyveg@aol.com and I’ll do my best to answer them.

Pests and diseases of vegetables
Had a talk at our Hort Soc last night on the above subject from Dave Thornton, General Secretary of the NVS. I made a note of some quite interesting points so here they are in no particular order whatsoever!
What a great web log. I spend hours on the net reading blogs, about tons of various subjects. I have to first of all give praise to whoever created your theme and second of all to you for writing what i can only describe as an fabulous article. I honestly believe there is a skill to writing articles that only very few posses and honestly you got it. The combining of demonstrative and upper-class content is by all odds super rare with the astronomic amount of blogs on the cyberspace.
