désherbant meaning in English

n. weed-killer
adj. weedy, pertaining to weeds

if , however , the same genetic engineering process also bred herbicide tolerance which maize could transfer to related wild plants , making them resistant to a particularly powerful weedkiller , i should then have reservations.
en revanche , si j'introduis dans le maïs une résistance herbicide contre un désherbant particulièrement agressif , j'ai des réserves.
