A method for use in detecting the presence of a target polypeptide in a weed, wherein the target polypeptide is connected with resistance of the weed to herbicides.
A method and composition for inhibiting the growth of a weed is described.
The herbicidal composition has an excellent control effect on weed.
The method comprises delivering to a sample of the weed an antiserum which is directed against the target polypeptide.
If the object has a spectral characteristic of a growing weed, then the valve is activated and the object is sprayed with herbicide.
When a preset depth has been reached, the cutter (5) is retracted in order to remove the core of earth and the weed from the ground.
Opposing claws may be mounted pivotally at the lower end of the cutter (5) in order to grip the root of the weed.
