You don’t spray roundup over vegetables and fruits

Farms do.

No. It's a weedkiller. Putting it ON the fruits would be expensive and useless.

In conventional/industrial agriculture, its used after harvest and before seeding. In intelligent agriculture , it's used a day before seeding.

So, why Monsanto went all the trouble of developing GMO crops resistant to it, if it is intended just for the weeds?

There is roundup-ready Cotton, Soybeans, Corn and Canola, that I am aware of. My family grows Roundup-ready cotton. The other 2 are used for animal feed; in no case is any farmer going to be spraying it when it is fruiting, because once the weeds have got to that point you've already lost all the benefit of it being 'roundup ready' - where the purpose is for weeds to be killed so they don't take the moisture which is now conserved for the crop.

There are no roundup-ready vegetables that I am aware of, or fruits.

There's RR Alfalfa as well, but your point still stands.

The seed of corn is a fruit, my guy. I'm talking botanically, not culinary.

Its also sprayed on crops as a desiccant shortly before harvest.

Round up or other herbicides are commonly used to uniformly kill and dry out mature wheat, corn, and other grains so harvesting and processing is easier.

I read the OP as making a specific claim about agricultural (not botanical) fruit harvests, not like the grains you mentioned.

Typically, yes that's the recommendation.

That doesn't mean it won't be applied at any other time if there's weed issues during other periods of the cycle, or that the farmer will apply it at the right time. A lot of farmers don't know when to apply herbicides, or won't until there are issues to save money.

I was working with a farmer who did most of it by hand or machine and he only needed to apply glyphosate twice in his 20 years as a farmer.
