The EPA under Trumps guiding scientific hand has or in the process of dropping a number of tests and test pieces of information. If it hasn't got a Canadian or EU approval on it don't buy!
Years ago Diazinon, an effective bug eradicator was banned from the market after it was proven it contributed to Altzheimers Disease. This proof came about by tracing generations of people out of a district in Quebec who were heavily using Diazinon for many years, even generations. And they compared the tests to another area in Quebec which had little-known use of the stuff.
This proof was accepted universally that Diazinon was the culprit.
Under new EPA rules, this decision could be set aside and this chemical, a systemic could be sold until new proof are put forward. The implications are extensive.
I don't know how bad and far-reaching his rules will go but, it is for sure, we should stay away from their products.
