Who Made Atrazine

The Syngenta corporation invented the herbicide atrazine and is its primary manufacturer. The corporation is certainly one of atrazine’s most ardent defenders and promoters.

When was atrazine introduced?

Atrazine was first registered as an herbicide in 1958. More than 70 million pounds have been applied annually in recent years, with about 75% of corn cropland receiving treatment.

What did Dr Tyrone Hayes discover about the N leopard frog?

Hayes found hermaphroditism in frogs at levels as low as 0.1 ppb. Even with today’s limits, levels of 40 ppb atrazine have been measured in rain and spring water in parts of the Midwest, while atrazine in agricultural runoff can be present at several parts per million.
