Giboulot claims the pesticide is ineffective and damaging to pollinating insects such as bees, and insists the disease can be fought via more natural means.
The 51-year-old is being prosecuted by a branch of the French agricultureministry, under article 251-20 of the rural code, for "failing to apply an insecticide treatment to his vineyard" in July last year.
The winemaker faces a six-month prison sentence and a €30,000 (£25,000) fine for refusing to spray his vines.
"It kills not only the insect but also other fauna that are necessary for the natural balance in a vineyard," Giboulot told Le Monde.
Denis Thiery, a vine specialist at the National Institute for Agronomic Research, also told Le Monde: "Even if Pyrevert is of natural origins it is damaging for the environment. It'sis a neurotoxin that can affect not just insects, but birds, other animals, even the winemakers, depending on the doses used.
Last June another organic winemaker was prosecuted and convicted for not treating his vines but was spared a prison sentence or fine after finally agreeing to spray against the disease.
Val says One would like to think sense would prevail but the department pressing the charge are adamant he should have sprayed... their law should be obeyed.
