White insects on my Rhubarb

My rhubarb in June, considering it’s growing in a large container, was relatively healthy.

This was my Rhubarb in June

I proudly harvested a small crop of rhubarb in June and left the rest to grow.

Then, today disaster struck.

Today I noticed lots of white bugs had taken up residence in the crown of the rhubarb.

I consulted Mr Google

According to Rhubarb Central

Rhubarb Pests are usually not a common problem for the rhubarb gardener. Rhubarb is a hardy and resistant type of plant, and not bothered by many pests.

I discovered white bugs in the rhubarb crown and crawling up the stalk

I think the white bugs are a member of the scale family, maybe mealy bug, so I’m going to treat my rhubarb by experimenting with the following methods.

Alcohol

Because the infestation is quite small at the moment I’m going to “spot” treat by dabbing alcohol, using a soft disposable cloth, directly on the insects and wiping them away as I do so.

Dishwashing Liquid

If this does not work I’m going to try the washing up liquid spray.
Dilute 50/50 with water. The theory is the soap suffocates the mealy bug.

I’m not sure if the above will work, but I will report back!

Any other suggestions as to the bugs identity and cures gratefully received!
