Nroso - a joke

[Jetemp]

@DrWazzock completely agree that using the lowest effect dose rate is the where every body wants to be, the issue comes where that rate is the maximum permissible dose rate. An overlap here can lead to a breach of mrls.

I'm not to concerned about the complexity of sprayers at the moment. Unfortunately the biggest scope for error is still the nut on the end of the steering wheel. the biggest scope for error for me is the guy or girl mixing the chemical into the spray tank, doesn't matter how complex the valve work all systems will have fail safes to prevent problems.

These modern machines with push button control, are generally set like they are to try and reduce pipe work so that there's not loads of dilute chemical left in the machine which can't be sprayed out

There are scientific relations between levels like LD50 (lethal dose 50, dose at which 50% of the poulation die), MRL's (maximum residue levels), ADI (acceptable daily intakes) and many other safety levels that are set with scientific assesmet and safety factors taken into account. The bells and whistles allow us to use products that may push these to the limits but without breaching them. No man is capable of doing this perfectly every time a computer is if set up correctly.

Some of these levels may sound pretty bring to most farmers, but t is part of the reason that bringing a pesticide to market costs so much.

Residue levels are measured in produce and used to show that products are being used in accordance with GAP (good agricultural practice). I can't remember where you go to find the test results but they are a public document. If residue levels of pesticides are regularly found in produce there is only really going to be one outcome, the loss of more products!

I would assume that no chemical that is passed for use on farm would be anywhere near the dose rate that would cause the LD50 or any safety level to be exceeded at well over twice the maximum application rate. Are you really suggesting that the authorities dont realise that some parts of a field will always have a double dose during a real field situation, an extremely small percentage of fields will be square and an exact multiple of boom/section widths, therefore the manufacturer will have to show that twice max rate is not going to exceed or probably anywhere near any safe levels, As for residue levels that is more likely to be caused by incorrect timings in most crops, different in veg as it doesnt get mixed up in a big heap.
I would think there are a lot more cases of over dosing by incorrect calculations when mixing and chucking in the last bit of a can than there is in the difference in a manual decision and a computer turning the section on and off.

@rob1 i probably didn't explain what I was trying to say particularly well, ld50 and other figures are used to calculate toxicity levels I am not suggesting that products that we apply are anything like these levels of toxicity. ADIs calculated from NOAEL with a safety factor built in.

Are you really suggesting that regulatory boards accept that we can apply chemicals over the max dose rate because are fields aren't regular shapes and don't fir in conveniently with boom sections widths. I can categorically state that they would expect you to miss a patch rather apply a product in excess of its maximum label dose rate, we can set our auto section nit t overlap if required.

I 100 percent agree that the biggest issues are cause by the operator and lack of regard for harvest intervals, but then it was suggested earlier on that a man, who potentially can't get the right amount of product in the tank was as good at turning the booms off at the right point with pin point accuracy every time like a computer is

Thats an interesting point never seen or heard what they think we should do about that, strange dont see many triangles with weeds so I reckon they have an idea what does happen.

Here's MRL limits in layman's terms - US I know but i've heard something similar at various events over here, if memory serves EU levels are significantly more restrictive than these... and no I haven't checked the maths!!

Bloody Hell ! we are discussing the pros and cons of Glyphosate on a NRoSO thread then , the link is good but off subject, this is discussing
operator continuous development /skills.

 

[The_Swede]

Just remebered hearing a similar statement and thought it led on from the above posts re overlap, dose, associated legislation etc etc

glufosinate ammonium is the same as glyphosate is it?

Sorry my mistake! should read more carefully

If you need up to12 points just register on fwi on the academy do 6 modules, 2 points each just a bit of reading then take the test only about 6 questions if you fail just do it again till you pass job done just remember to Before completing any courses, you’ll need to add your CPD membership numbers to your profile.
To add your membership number, sign in and go to your profile. Click on the CPD Schemes tab and enter in your details.

If you've used the FWi Academy it may be worth emailing NRoSO to check they've got your points recorded; I've emailed them today and apparently there are sometimes problems with tallying the Academy records with the NRoSO ones. I found some of the modules in the Academy really interesting, my arable knowledge is not the best so I'm glad the information is there to be read.

any1 else been on the yearly half day course yet? went thismorning to coldstream, hosted by Agrii, bacon roll and tea/coffee on arrival at 930,a quick natter about latest rules n regs, more tea/coffee/biscuits at half 10, a bit more natter about PPE, knapsack sprayers and slug pelleters then soup n sandwiches and a pint (if you wanted 1) at half 12, 10pts job sorted for another year

 

[Sonoftheheir]

I honestly think they've run out of things to talk about.

 

[Heathland]

Went on Wednesday,at least now I can calibrate a knapsack sprayer,if I had one.When the room was asked who had got a knapsack sprayer,not one hand went up ,13 people on the course ..

Same on mine.

They have got through some very important stuff before but I think it's all been done now.

Same at our meeting. Telling us about knapsack but no one in the room could legally use one as apparently you need a PA6!! The topical update at the end is good. And the chips and sandwiches

Which one did you go to? My lads are going to the CMP one at the Langton Arms at the end of the month. Lunch provided.

 

[dazza b]

The best thing about the course is the topical updates this were I find you learn why and how

 

[Cab-over Pete]

I go every year to the NAAC course hosted by David Felce. He's a good bloke and doesn't waste our time on the real basics.

I've been on every one for maybe 8-9 years despite not owning or using a sprayer at all until last summer. From my point of view there was always something to learn.

Great attitude to have. I believe those who think they know it all oftem know nowt I'm 53 and still ;learning every day............ Or am I just particularly slow

 

[spin cycle]

because i've left farm assurance i'm not planning to renew my membership....i have to say i'm completely disillusioned with it.....in the years i've been going to these things and catchment meetings ect i've not seen ANY evidence that pollution is falling and indeed when i asked about the wqfd in 2015....the silence was deafening.....i had to find out myself that it had been put back to 2020....then 2027.....so for 4 years 2010-14 we were beaten with a stick that they threw away in 2015

i did change the way i do my spraying but i think a lot ppl turn up ,eat the bacon sandwich, but not change their practices

next question is....can i leave or will i be 'struck off' for not paying?.....will i remain on any databases and who will have access to it?
