Pre em on beans...how late can you leave it?

[Louis Mc]

I was think of instead of burning off cover day before drilling and spray pre me the day after, how about just drilling the beans, then 7/10 days later spray pre em and glyph together??

Can be done no problem - just be confident the bean slot isn't exposed

becarefull if heavy rain forecast for the 48 hours after spraying

I do not use a preem on beans because in 2012 heavy rain after spraying hammered the beans on heavy sticky soil

 

[Louis Mc]

To be honest I am wondering if there's any need for pre ems and will try some without. Will be a nice mat of oats to form a mulch

I'm thinking of leaving the middle of one field and broadcasting my own weeds aka white clover.

What do you do instead? Nirvana i usually use. 3lha.

You may get a few more annyoing dirty broadleaves in the crop

I used to do glyph and nirvana 7 to 10 days after drilling without issues. Now I only use nirvana on any areas where there is a risk of a poor crop, and just glyph on the rest. Nirvana does help kill rosebay willow herb, but is an expensive way of doing it!

No till beans are just so much cleaner than with tillage.

Last year on the advice of @yellow belly I drilled the beans later and left out the pre-em and went through with some Troy later. One field had no herbicide and was spotless. A history of heavy chemical use meaning limited seed bank, other than bg, and dd might have helped

I'm tempted to give that a go rather than Nirvana - think I'll do a trial.

Bentazone is on the to be banned list though!

Use it while you can, at least you have the option to use it as required. TBH there is no profit in spring beans here anymore so costs need to be controlled, they were once the top paying crop so the smaller the area the better.

I didn't use a pre em last year drilling into a good cover and had no problems at all, so I don't intend using one this year

I do my glyphosate with the pre em on spring beans. Has worked a treat the last 2 years.

I have used avadex prem but now sadly not on the label

if you have land that has been winter cropped for years 20 or more there is often no spring germinating weeds

charlock may be a problem if too much weedy rape has been grown but if notill and a clean cereal crop prior the weeds that grow after mid aprill can often be absent a thick layer of straw can help with charlock but may also keep the soil cold

if a field has had weedy march planted spring crops in the past mid april planting can bypass the weeds bit high seed rates are essential 60 or more seeds per m

Rosebay willow herb is the problem here and seems to appear from nowhere.
