Weedy carrots...and onions.

[Stuart J]

Grow a few beds of carrots for an on farm shop.
Got a bit distracted this year with my wedding so now I have carrot beds which also contain mature chickweed, redshank and knotgrass as well as amg.

Is there anything i can do for them now?
Linuron? Any other options uncluding eamu's ?

Similar question applies to onions!

Hand pull the weeds?

 

[Bogweevil]

What are the carrot roots and onion bulbs are like? There is critical period and the crop can tolerate weeds after a certain stage. If carrots were weed free for six weeks or so after emergence the crop might not be too badly compromised. Weed pulling might do more harm than good, but on the other hand harvesting machinery might not function in a weedy crop but I expect you are hand harvesting for a farm shop.

Carrots and onions both half the size I'd like.

Hand weeding not an option.

I dont think you have any option

Carrots - go with 1 L/ha Linuron + 2.5 L/ha Defy and repeat in 7-10 days time

Onions - go with 0.5 L/ha Buctril + 2.0 L/ha Defy

the one problem weed that you have is knotgrass which is a pig to kill

Can you still get linuron? I thought it was on use up only. All approvals have expired & there's only Afalon on an EAMU left until October

Linuron sales ended 3 June 2017, so I hope that StuartJ has a can left in the store to use up before the end of this September.

Carrot and parsnip growers will particularly miss Linuron next year. There is a replacement herbicide coming along which is already used in Belgium/Holland, but no guarantee of it being approved in the UK.

Was not the use up date 3 June 2018? https://www.hortweek.com/loss-linur...ect-alternative/fresh-produce/article/1427716

they got a Linuron use extension until the end of Sept - because of the late spring.
