Heavy shower after spraying.

[Greythundercloudys]

Had a guy spray 30acres of rushes today. He finished around 2, but just there at 4,20 was a heavy shower for 10min, would that have washed this last lot of, the other should be fine as he did most of it in the morning.

If it take that to get some rain I'm goin spray 100 acres

 

[Derrick Hughes]

What did you spray it with.?

 

[Greythundercloudys]

Larke, very strong old rushes, 15 litres to 1200 litres water, so very strong mix.

Never had issues with rain after spraying. Even stopped midway through a field to let an April shower pass then carried on again.

How many litres per acre . That's MCPA?
Did you have a bargain ?

 

[Greythundercloudys]

Not sure, yes larke is mspa, just left it to the sprayer man, big amazon, like a spaceship. Big John deere with sat guidence, a great outfit, those rushes will be all dead next year going buy the soaking they got.

Think you should spray it again.

Do you think you could make a claim against the rain?

 

[Greythundercloudys]

Defo won't be spraying again, it will just have to either work or not, but as l said most got 4 or 5 hrs dry, time will tell.

Be fine

Spraying big strong old rushes isn’t the best for long term control.
They really should be young and actively growing and hit before seed head appears. They are really susceptible to MCPA then, and transfer the kill effect right to the roots.

Will be fine. Spray will have evaporated by then.

Had a field of long term grass sprayed off once, rained 30 minutes after the sprayer left the field. Still worked. That's why I used so much premium glyphosate and adjuvant.

I would put my money on Larke being fine, NuFarm make good stuff.

Sprayed the Spring Barley yesterday, it seemed a good day when he loaded up but rained 10 mins after he finished, a nasty shower and rained on and off all afternoon. I wish I shared some of the optimism on here.
