The French bailiff Benoît Raclet (1780-1844) married into a family of winegrowers. He is considered the inventor of an effective measure to control the caterpillars of the dreaded vine pest grape berry moth
, which severely damaged the vineyards of the Mâconnais
in the first half of the 19th century. The invention was the result of good observation. The Raclets' vine plots were infested with the caterpillars (hayworm, sour worm), as were those of their neighbours, and only one vine was unharmed. This vine stood in front of the kitchen window, from which his wife always poured out the hot water after washing up. The vine was regularly doused with water. Raclet correctly concluded that the pests were scalded.
