I checked my blackcurrants yesterday and some have Big Bud.  I check every year and this is the first time I have seen them.
These are caused by an almost microscopic mite and can lead to reversion virus.  The buds are spherical, often look dead and generally do not open.  According to the RHS there is no insecticide available to the amateur.  Their advice is to pick off and burn the affected buds.  They say the mites overwinter then in April to June migrate and infect other buds.  So now is the time to check and remove any spherical buds or any that do not open.  Apparently when migrating from an infected bud to another they sometimes get blown around and that is how the infection spreads. They do sometimes infect red and white currants - however, they cause little problem with these.

Last year and the year before I saved runner bean and climbing French bean seed.
Saving your own seed from peas and beans is easy.  They nearly always come true, even if grown next to other varieties.  I have grown peas and mange tout next to each other, saved the seed and both came up true - better than the bought see!  So have a bit of fun, save a few pence and save your own.  Many tomatoes are also said to come true from saved seed, I know Gardeners Delight come true but F1’s and Marmande do not.  If it says F1 or needs insect pollination, don’t bother.

Parsnip Rash/Burns
Parsnip sap (and giant hogweed sap)  on your skin in good sunlight leads to a photochemical reaction which causes nasty blistering and irritation.  This is followed by scaring which is reported to last from 3 months to 2 years. Everyone is susceptible.   
It is most likely during good growing conditions (wet and warm) when the sap is plentiful. The likelihood of getting it in the winter when parsnips are normally harvested is far less likely; less sap, less sun and generally better covered up against the cold.                                                                      from Barrie Richardson
