Slight correction, it leads to loads of herbicide usage (glyphosate). The process of desiccation also leads to loads of glyphosate being used just prior to harvest, on non ‘Roundup Ready’ (glyphosate resistant) crops, which may be worse as it doesn’t get rinsed off since it’s used in the drying phase.

- sjg007 4y agoUmmm no, less herbicide actually
- margalabargala 4y agoI think you might be confusing herbicides and pesticides. Some GMO crops can lead to less pesticide usage as the plants can sometimes be engineered to be resistant to the pests targeted. Weed plants don't generally attack the crop plant directly, instead they merely grow nearby and compete for various resources that the crops would otherwise be able to use. GMO crops can be engineered to be resistant to specific herbicides. This leads to more of that herbicide (generally glyphosate) being used, since more herbicide = fewer weeds, and amounts of glyphosate that would kill non-GMO crops are tolerated by GMO crops.
- sjg007 4y agoNope I meant herbicide. Look it up.
- _jal 4y agoNo. If you want your assertions to be taken seriously around here, providing your own citations for your claims would help.
- sjg007 4y agoYou all think you know what you are talking about but never look at the research. https://www.nature.com/articles/ncomms14865 https://www.nature.com/articles/ncomms14865

- _jal 4y agoI look at research. And in this case, it contradicts your claim. "A steady, linear trend for increasing number of herbicide area-treatments over the last 25 years was observed for all crops except soybean. The linear trend was not statistically significant for soybean [...]"
- sjg007 4y agoTalk about selective quoting… Read the whole paragraph. Less herbicide if the crop is roundup ready.
- _jal 4y agoTo recap, you contradicted drewmal above, who said: > it leads to loads of herbicide usage (glyphosate). The process of desiccation also leads to loads of glyphosate being used just prior to harvest, on non ‘Roundup Ready’ (glyphosate resistant) crops You replied "Ummm no, less herbicide actually". The Nature study you claimed supported your assertion said herbicide usage was steadily up, and more was used on non-roundup-ready crops. I don't know if you meant "no" to reply to one or the other of those claims or both, but it doesn't matter because they both agree with drewmal.
- sjg007 4y agoDrewmal is wrong, it’s just nonsense. Call up your local university extension program and ask. Not hard.
- drewmol 4y agoCare to elaborate? Roundup ready crops have glyphosate resistance which allows for broad application of the herbicide on a field to kill off unwanted other crops, weeds, while not harming the crops with genetically engineered resistance. Otherwise, the application of herbicide would need to be targeted to only the unwanted plants, which is a more labor intensive process. Unless I’m misunderstanding something?
- sjg007 4y agoWe use less herbicide if the crop is roundup ready vs conventional crops.
- colechristensen 4y agoGMO crops lead to different herbicide usage, not necessarily more, and it’s not quite clear how to compare what is “more” between two herbicides anyway. The alternatives to glyphosphate are quite a bit more concerning when it comes to human toxicity. This bit about desiccation sounds like it isn’t very common at all, in a quick search I wasn’t able to find references to it from an ag university extension… and it would be quite expensive and hard to justify.
