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. [15] [19]
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 ...
pimobendan – phosphodiesterase 3 inhibitor used to manage heart failure in dogs; pirlimycin – antimicrobial; ponazuril – anticoccidial; praziquantel – treatment of infestations of the tapeworms Dipylidium caninum, Taenia pisiformis, Echinococcus granulosus; prazosin – sympatholytic used in hypertension and abnormal muscle contractions
AMPA is one of the primary degradation products of the herbicide glyphosate. [4] [1] In addition, it is a degradation product of other aminophosphonates, which have applications as antiscalant and water treatment. [5] AMPA was found in the final effluent of some wastewater treatment plants at concentrations of up to 10μg/l. [6]
A reference dose is the United States Environmental Protection Agency's maximum acceptable oral dose of a toxic substance, "below which no adverse noncancer health effects should result from a lifetime of exposure". Reference doses have been most commonly determined for pesticides. The EPA defines an oral reference dose (abbreviated RfD) as:
Specific treatments for acute pesticide poisoning are often dependent on the pesticide or class of pesticide responsible for the poisoning. However, there are basic management techniques that are applicable to most acute poisonings, including skin decontamination, airway protection, gastrointestinal decontamination, and seizure treatment.

The lethal dose for 50% of dogs is 100 – 200 mg per kilogram (kg) of body weight, yet some dogs will exhibit signs of toxicosis after ingesting as little as 20 mg per kg. [38] In case of accidental intake of chocolate, especially involving a smaller dog, contact a veterinarian or animal poison control immediately; it is commonly recommended ...
