Allotments 4 All

Good morning everyone

For a couple of weeks now I have notice small holes appearing in my brussels I keep looking for culprits but can't see anything, it seems to be spreading to my cabbages as well still can't see any thing munching.

Does any one have any idea what may be the problem, and a cure ?

Many thanks

Flea beetle ???  My brassicas last year looked like they had been attacked  with buckshot !!

Flea beetle is the biggest nuisance on my plot these days, they are so small only micronet keeps them out, and its too expensive over big brassica beds.

Derris dust keeps them down, but the frequent rain means regular re-applications

Many thanks

I will try the Derris dust
