For a herbicide to kill a plant, the herbicide needs to be absorbed by the plant, be moved to its site of action while remaining intact and inhibit its target enzyme. Herbicide resistance in weeds occurs as a result of changes that prevent the herbicide from effectively inhibiting the target. While resistance could be the result of a change that affects any one of the processes described above, in practice three types of resistance mechanism are observed.

How do you kill a cypress tree and its roots?
herbicide that kills cypress tree?
What is an example of a living organism that has recently changed due to natural selection?
The high death rate of people who play golf in a thunder storm. And of skateboarders on steep roads.add And the evolution of insecticide resistance by insects, and herbicide resistance by plants. Even if the challenge were removed, if the newly developed variant were in the majority, the old variant may well still fail to prosper.
How genetic engineering is used in agriculture?
In the USA, there are at least three major ways that genetic engineering is used in agriculture that I know of. Probably the most well known: herbicide resistance such as Glyphosphate resistant has been genetically engineered into crops (beans, corn, for ex) so that farmers can then apply Glyphospate to fields, killing the nonresistant weeds. Another example - the gene that encodes the insecticidal crystal protein of Bacillusthuringiensis has been introduced into some crop plants to make these plants lethal to herbaceous insect pests. A third example - scientists have introduced genes that produce nutrients, such as carotene into staple foods such as rice. The first two applications are controversial, as evidence of herbicide and insecticidal resistance spreading to "weeds" has been confirmed.
What are ingredients in herbicides?
Depending on the herbacide, the ingredients vary. Read the label on a container of herbicide it will have a list of ingredients.
What is human body resistance to electricity if skin is wet?
human body resistance to electricity when skin is wet is 1,000 ohm and when skin is dry its resistance is 100ohm

What is a potential health problem that could arise from genetic engineering?
Sample answer: Engineered traits such as herbicide resistance could transfer to weeds and create "superweeds."

How is the herbicide-resistance gene cut out of this structure?
One might find this answer when looking for books in a library on Genetic Engineering. Another way one might find out how the herbicide resistance gene is cut out of chromosomes by asking a genetic physicist.
When a new part appears in an organism or when it changes its form you call this change?
It could be metamorphosis in the caterpillar to butterfly transform.It could be called natural selection, or evolutionwhen the organism changes to meet a new challenge. Such as herbicide resistance in weeds, or drug resistance in bacteria.
How does using herbicide tolerant crops increase herbicide use?
Because the crop you are using is tolerant to the herbicide you are using, you can use more before it will damage the crop. Because of this, you use more herbicide to kill the unwanted flora.
How do you control clover when there is an herbicide ban where you live?
You use a herbicide to control clover not a pesticide.
What are is the Difference between a herbicide and an insecticide?
A herbicide kills weeds and an insecticide kills insects. :)
What does herbicide means?
If hoeing doesn't remove all the weeds from your flower bed you may need to resort to using a herbicide.
How does the herbicide Basta work?
The herbicide Basta works in an intricate way dealing with the systemic process of the plants which it is used to kill. The herbicide is taken into the plants through the roots and then the plant will distribute it throughout the body of the plant to areas where the herbicide can take its effect.
