That would see the current LFASS budget of PS65 million drop by around PS13 million.
Earlier this year, the Scottish Government said it intended to"effectively reinstate funding levels to 100 per cent of LFASS".
European Union rules require LFASS payments for 2019, due next spring, to reduce by 20% resulting in a PS13 million cut to the scheme's PS65m budget.
NFU Scotland (NFUS) has written to Rural Economy Secretary, Fergus Ewing, asking that he honours his promise to reinstate LFASS funding levels to 100%.
"With these payments we will have now made over PS39m of LFASS
2018 payments, directly supporting our vital remote and rural communities and economies," said Mrs Gougeon.
And the NBA is also to resist simultaneous efforts to give less LFASS
support to farms which could fall down the grazing category payment ladder because they have reduced stock numbers.
