Flat rolling osr to help battle against CSFB

[samsung]

Will flat rolling after drilling have any effect on csfb once the crop emerges.
Just wondered if the change in environment would change their behaviour. My agronomist has recommended 2 passes with ring rolls to close it up more. Thanks.

In a word......no

can’t see what it does to CSFB

Will aid establishment in a dry time though

CSFB. is just pot luck / area now - nothing you can really do about it other than limit your risk, do not spent on OSR until sure you have a crop

I flat rolled after planting my osr last autumn. It did a lovely job with closing the ground up, but didn't help at all with flea beetle. Just finished planting the 16ha with peas.

Reducing the surface area of the soil gives them less places to hide when you’re out with a sprayer selecting the resistant ones with an insecticide, that’s all. Double rolling mine made me feel better but didn’t really make much difference. They are flying in swarms as the crop emerges, so you’re giving them an easier landing

Rolling post emergence risks snapping the stems and killing the plant. You might give a couple of flea beetles a headache too.

Wishful thinking? May get it established in autumn. No guarantee larva will not take it out in March. Hey ho.

Flat rolling was the only treatment in pre chemical days

No, nor will Garlic sprays, citrus sprays or pyrethroids. In fact I have found shouting at CSFB to be just as effective as any of the above.

Good rolling might help better establishment which will help the plant outgrow the pest.
