what do you spray peas with    to stop the maggot from getting in

[mumofstig]

I don't spray - the earliest sowings seem to miss them anyway

the RHS lists a couple of sprays

If you net them with debris netting, that also helps. I did a late sowing last year and covered with debris netting when they started to flower and didn't get any pea moth issues.

I never spray mine either, just sow early, harvest the lot and freeze them

Mangetout I harvest over a longer period, but if there are any grubs in those tiny peas they certainly aren't ever seen.

I like the idea of growing a late crop under debris netting, White Rabbit... I guess they would have to be  a shorter variety though?

I grew Kelvedon Wonder and Ambassador until debris netting. I just loosely draped it over some 2x2 hammered into the ground to give the height required.

Looking back at my diary, I sowed them late June and picked in September.

They sound ideal

The moths lay their eggs at the base of the flower buds before they open. The maggots hatch out and burrow their way into the embryo pods in the flowers. They then commence to feed on the developing peas.

Once the maggots have burrowed into the pods none of the approved chemicals will kill them. Hence the RHS advice to spray twice, a week apart, as they are only effective between when the eggs are laid and when the maggots burrow in. In commercial crops the sprays will no doubt kill the adult moths as well but the chances of them being present in your 20ft row when you spray must be small.

If you put netting( enviromesh/debris netting) on as soon as you see the first flower buds are developing and keep it on until all the pods have formed you should not have any problem from pea moth. In practice I usually leave mine on until picking as it keeps off the pigeons.

great    thank you all

Re mangetout - they can be there - just not visible!

Meaty peas

[ghost61]

I net my peas as soon as they are sown.  Stops the birds eTing the shoots too, as well as pea moth.  We construct a cage much like already suggested with wires across to support the netting - also make them highish so weeding isn't too onerous!

Meaty peas

That's why they're called "mange tout"!
