Spring beans after a cover crop.

[Richard III]

A couple of people asked to be kept updated from this picture posted in the 'Cleavers in spring beans', so I thought I would stick the pictures into a new thread. They were drilled on the 19th of March and then sprayed with Nirvana and 1.8l of glyphosate on the 29th of March.

The crop today on the 29th of April.

I'm pleased with how the beans are growing, but unfortunately some of the fodder radish in the cover crop snapped off at drilling and are now regrowing from the tap root.

Where the radish were smaller there is no problem, but I have sprayed 9 acres with full rate Basagran today. Also the odd oat has survived in the thickest patches of cover and look like they will have to be sprayed out too. It's only been a problem because of the massive cover crop growth due to the mild winter, but it looks like another lesson learnt the hard way.

I drilled some beans into some heavy soil on the 21st of March, the soil was very sticky, but I wanted to get finished to go on holiday.

The same field has some beans after cover, the beans sown into cover are definitely growing faster this year and will pod higher up the stem, I think the dead cover has given shelter from the cold winds.

I cant really tell from the pictures, but both look a bit thin to me. Could you say how many seeds per m2 you drilled, and how many have emerged? Probably no more to come through now? What was your target plant stand?

Richard, the beans after the cover look fine to me. The ones into wet look like my winter beans this year in December, quite a lot failed to grow. You will have to add the yield difference to the cost of your holiday.

When did you spray off the cover, how long before drilling? Did the glyphosate not have time to get into the radish roots before they were snapped off. I find cover crops need two goes with the sprayer to get everything, especially thick patches of blackgrass.

The beans are a little thin, I aimed for 40 seeds/m, which worked out at 300kg/ha. I weighed the correct amount of seed straight out of the heap through a keenan feeder earlier in the year, but ended up with about 10% left over. It is something my drill appears a little prone to do sometimes, I put it down to the spider wheel slipping in some conditions.

I'm not too concerned, it might be my cooler wetter climate, but from experience a stand like that will do fine here most years.

Hi Simon, I sprayed the cover off 10 days after drilling, along with applying the Nirvana. I usually spray the day before drilling and then apply Nirvana a few days later, this has always worked well and the Nirvana tends to burn off anything in the bottom that might have been sheltered a little from the glyphosate. With the covers being so large this year I really disliked the idea of terminating all that large root system with glyphosate, as we have discussed in the past. The idea was that the Sim-Tec would mechanically terminate about 30% of the cover, leave the rest a few days to recover and then terminate the rest with glyphosate. It has worked on about 50% of the area, 50% will need a splash of graminicide to take the odd oat out, about 10% has been sprayed with Basagran and I will hand pull a few. From what I have seen this year the technique works here with average sized covers, thicker covers need spraying before drilling, then if there is radish in the mix and they are over about 80cm tall, then the glyphosate needs time to translocate. If I had black grass, then I think I would be spraying twice too.

I would be inclined to add a whiff of Hormone in too ...24-D or its equivalent glyphosate on its own sometimes may not be enough

Taken today, giving them a dose of signum and phosphite.

 

[TelesnaAg]

Richard v 3rd...handy enough looking stand...signum (what is this?) and phosphate...do you make your own liquid phos or do you buy a product specifically for foliar application? I have a faba bean trail in this year to see how they go...

Any info appreciated..

Ant....

 

[Richard III]

Hi Ant,

Signum is fungicide for chocolate spot and rust control.

http://www.agricentre.basf.co.uk/agroportal/uk/media/product_files_uk/labels/Signum.pdf

I would rather be using straight chlorothalonil and metalaxyl, but we don't have approval to use these chemicals in beans any more over here, unless in expensive mixtures.

The phosphite is applied at 1l/hectare to help with downy mildew control, and is only available as a liquid. Phosphite and phosphate are very different in their effects on the plant.

Cheers R3...they tend to use different names over here for same stuff sometimes.

Does anyone do Beans full season over there or only as a spring crop? I have planted mine 1 month after the wheat ...to slow vegetation growth down as i'm close to coast...

Do you guys use Prosaro over there? my Agronomist suggested it for eyespot in wheat - its $700 AUS for 10L or $49 ha...

Active ingredients
prothioconazole 210 g/L
tebuconazole 210 g/L

I now do not put radish in before any non-spring cereal crop. Learnt that last year in spring rape. Radish grew from rotting tubers. Not much help to you now though. Beans look well.

Thanks for that Andy, looks like I will have to cross them off my list of possible cover ingredients too, many of the radish tubers now have three strong shoots coming off them. Fortunately the bean crop is quite thick and vigorous, but unfortunately the field is alongside the main road and has quite a few observers.

do you mean spring non-cereal crop?

Yes

Winter Beans (full season) are grown in the uk , normally sown about 2 months after wheat harvest, and are grown here probably as much as spring ones.
Prosaro - Yes it is used here, usually in combination with other products.

I am right in thinking you have beans with and without previous cover crop ?
Do they look any different?

maybe some hormo0ne to reduce the throwing of of the 1st set of flowering buds to increase yield by at least 50%. 8+ t/ha of beans have been achieved so far. I reckon that with this yield a 2nd wheat will have a tough time to compete

Who sells the product you are referring to ?

 

[stroller]

What is phosphite and who sells it?
