Glyphosate (Roundup) is the principal pre-harvest systemic herbicide used for desiccation of a wide variety of crops. As a systemic herbicide it is not a true desiccant as it can take weeks rather than days for the crop to die back and dry out after application.
Glyphosate is also used for crop desiccation to increase harvest yield and uniformity. [57] Glyphosate itself is not a chemical desiccant; rather crop desiccants are so named because application just before harvest kills the crop plants so that the food crop dries from normal environmental conditions ("dry-down") more quickly and evenly.
The glyphosate-based herbicide RoundUp (styled: Roundup) was developed in the 1970s by Monsanto. Glyphosate was first registered for use in the U.S. in 1974. [4] Glyphosate-based herbicides were initially used in a similar way to paraquat and diquat, as non-selective herbicides. Attempts were made to apply them to row crops, but problems with ...
The use of glyphosate-based pesticides are not considered the major cause of amphibian decline, the bulk of which occurred prior to widespread use of glyphosate or in pristine tropical areas with minimal glyphosate exposure. [28] A 2000 review of the toxicological data on Roundup concluded that "for terrestrial uses of Roundup minimal acute and ...
One example is the "double knock" system used in Australia. [35] Before planting a crop, weeds are sprayed with glyphosate first, then followed seven to ten days later by a paraquat herbicide. Although twice as expensive as using a single glyphosate spray, the "Double Knock" system is widely relied upon by farmers as a resistance management ...
NEW YORK (Reuters) -The man accused of killing a woman sleeping on a New York City subway car by setting her on fire after what prosecutors say was a night of heavy drinking pleaded not guilty to ...
Diquat is the ISO common name [4] for an organic dication that, as a salt with counterions such as bromide or chloride is used as a contact herbicide that produces desiccation and defoliation. Diquat is no longer approved for use in the European Union , although its registration in many other countries including the USA is still valid.
