How do weed killers work?

Weed killers, or herbicides, work by blocking the growth of cells in plants. When you apply them, the chemicals will target the enzymes that produce or form fats. As a result, it will halt the development cycle of the cells and kill them.

Understand that the enzymes that allow cell growth in weeds with broad leaves are not the same as those in grassy plants. Thus, some herbicides will only work on grassy-type weeds and others on broadleaf weeds.

What dangers do weed killers pose to pets?

Weed killers can be poisonous to your pets. Depending on the ingredients used to make the herbicide, it can cause different effects on a dog or cat.

For example, products that have glyphosate can cause lethargy, anorexia, and vomiting in animals. Tremors, dilated pupils, diarrhea, and drowsiness are other effects of the herbicide on pets.

Apart from glyphosate, chlorophenoxy derivative weed killers, such as MCPA, can irritate the pets and cause salivation, abdominal discomfort, and vomiting.

In severe cases, there may be progressive weaknesses, anorexia, and blood in the stool of the animals. Thus, only use a pet-friendly weed killer to protect your dog or cat.

When is the best time to use weed killers?

You can apply a weed killer at any time of the year. However, the best time to use herbicides is when the plants have started to sprout, usually in autumn and spring. During this time, the rhizomes absorb the chemicals more quickly.

Another point to note is that herbicides can either be pre-emergent or post-emergent.

The former helps to disrupt the life cycle of the plants, especially when dealing with annual problems like summer weeds. In that case, you can apply them before the seeds of the plants start to germinate.

Post-emergent weed killers eliminate weeds upon contact. Once you apply them, the plants will absorb the chemicals and wilt within hours.

The best time to use the herbicides is when the weeds are new and young. For rhizomes that have already established, start by cutting them down and wait until they start growing.
