What pesticide can be used to kill trees

In life, many trees wither and die due to external factors, and if these trees grow in fields, they will affect the planting of crops, so what pesticide can be used to kill trees?

1. Fenoxaprop-P-ethyl + glyphosate

First, fenoxaprop-P-ethyl has a very good killing effect on the stems and leaves of perennial weeds. Second, glyphosate can kill the stems and roots of perennial weeds. When these two are combined and applied, they can kill the roots of many-year-old trees!

2. Drench the roots with salt water

Use table salt to dehydrate the tree roots, thereby achieving the purpose of killing the tree roots. However, in this case quite a lot of table salt is needed. It is best to dig a pit near the tree roots, then pour the table salt into the pit, then cover it with soil, so that the table salt soaks into the tree roots, thereby causing the tree roots to dehydrate, and then die.

3. Drench the roots with sulfuric acid or hydrochloric acid

Concentrated sulfuric acid or hydrochloric acid can both destroy the nutrient metabolism of the roots and disrupt the acid-base balance of the roots, causing the tree roots to burn to death quickly. This is also a method that can remove tree roots.

4. Use quicklime to burn the roots

By taking advantage of the property that quicklime releases a large amount of heat when it meets water, it scalds the tissue and organs of the roots, especially the absorptive tissues of the roots, so that the tree roots cannot absorb water, fertilizer and other nutrients, and this can also kill and remove tree roots.

In short, to kill tree roots, in addition to pesticides such as paraquat and glyphosate, methods such as concentrated sulfuric acid, concentrated hydrochloric acid, quicklime and salt water can also be used to kill tree roots. The specific one to use can be determined according to the actual situation.
