Mutant Pigweed vs. Glysophate-Resistant Corn, Soybeans, and Cotton

It’s a funny thing about monocultures. They’re highly vulnerable to anything that affects that particular variety. Dr. Mae-Wan Ho writes:
The scene is set at harvest time in Arkansas October 2009. Grim-faced farmers and scientists speak from fields infested with giant pigweed plants that can withstand as much glyphosate herbicide as you can afford to douse on them. One farmer spent US$0.5 million in three months trying to clear the monster weeds in vain; they stop combine harvesters and break hand tools. Already, an estimated one million acres of soybean and cotton crops in Arkansas have become infested.

The palmer amaranth or palmer pigweed is the most dreaded weed. It can grow 7-8 feet tall, withstand withering heat and prolonged droughts, produce thousands of seeds and has a root system that drains nutrients away from crops. If left unchecked, it would take over a field in a year.

Bladderwort?

I think that’s bladderwort, which is a carnivorous plant that eats small insects.

And for another color:
