What are the methods for making your own root-killing herbicide?

Herbicides are an extremely important part of farming. Many weeds are tenacious and highly harmful to crops, yet many herbicides have a rather narrow effect, so how do you make a homemade root-killing herbicide?

1. What is an herbicide?

An herbicide refers to a chemical agent that can cause weeds to die off completely or selectively. The commonly used varieties are organic compounds, and they can be widely used to control harmful plants such as weeds, scrub and trees in farmland, orchards, reservoirs, warehouses and other places.

Herbicides can be classified in many ways, such as by mode of action, site of application and source of the compound. According to their action characteristics, herbicides are usually divided into two main categories: pre-emergence herbicides and post-emergence herbicides.

Pre-emergence herbicides are also called soil-treatment herbicides. This type of herbicide can only be used before the weeds sprout and emerge, or during emergence; if used after the weeds have emerged, it is basically ineffective against them.

Post-emergence herbicides are also called stem-and-leaf treatment herbicides. This type of herbicide is usually used during the period of vigorous vegetative growth after the weeds have emerged, and it is basically ineffective against weeds in the soil that have not yet sprouted.

2. How do you make a homemade root-killing herbicide?

1. You can mix 30% glyphosate + 6% glufosinate to make a herbicide with a long residual effect, a broad weed-killing spectrum and fairly fast weed-killing action.

Glyphosate is a systemic herbicide that can kill the roots, stems and leaves of the plant, but its weed-killing action is slow, generally requiring 15 to 20 days. Glufosinate is a broad-spectrum contact herbicide with weak systemic action; it mainly kills the above-ground parts of the plant and has no effect on the roots. The mixture of the two has both systemic and contact action.

2. You can also make a herbicide from quizalofop-p-ethyl, fluoroglycofen-ethyl and glyphosate in a certain ratio; the resulting herbicide kills the greatest variety of weeds.

If you do not understand herbicide mixing, it is best to buy a herbicide already mixed by the manufacturer, so as to avoid harming crops.
