Introduction

Weeds are a common problem in many yards and gardens. They can take over your lawn, smother your flowers, and generally make a mess. If you are dealing with weeds, you are probably looking for a way to get rid of them quickly and effectively. The good news is that there are several different options for controlling weeds, and one of them is a post-emergent crest

What is a post-emergent herbicide?

A post-emergent herbicide is a type of herbicide that is applied to plants after they have already sprouted and begun to grow. These products work by destroying the foliage of the weed, the roots, or both. This type of herbicide is ideal for people who missed their weed treatment when the weeds were still in seed.

Advantages of post-emergent herbicide

There are many advantages of such remedies:

  • They work faster. Post-emergent herbicides kill weeds quickly, so you don’t have to wait as long to see results.
  • They are more effective. Because post-emergent herbicides target actively growing weeds, they are often more effective than pre-emergent herbicides;
  • Post-emergent herbicides can help remove weeds of any age from an overgrown yard that other eradicators can’t handle;
  • Suitable for the beginner gardener to treat, as he will then be able to see what he is treating. A specific weed will require a product, and if you take a pre-emergent herbicide, it is more difficult to use, because the weeds are not there yet, so it is difficult to determine their presence in a particular place.

Type of post-emergent herbicide

There are three types of post-emergent herbicide:

Selictic – this type acts gently and delicately. They are most often used in areas where there is a lot of important and valuable vegetation that you want to preserve. A celictic herbicide works gently without affecting the health and integrity of valuable plants;

Non-selictic – this type of post-emergent herbicide is harsher and more aggressive due to its more chemical composition. This option is best applied to hardy weeds that are difficult to remove from your garden. But remember that this type of product can damage and even kill valuable plants in your garden. That’s why it’s important to treat weeds with this type of weed remedy on a point-by-point basis to minimize the risk to valuable plants;

For trees and bushes – this kind of post-emergent herbicide is quite rare, but very effective. It is used to treat stumps, after cutting a tree, to control the growth of bushes, to treat the fence along the forest area, etc.

Form of post-emergent herbicides

There are different post-emergent herbicides available in different forms:

  • Liquid – can be marketed as a concentrate that must be diluted with water afterwards. Concentrates are best for treating large areas where there are many weeds. In this case, you can save money on the purchase. The second option is a ready-to-use product that is ready to kill weeds immediately after purchase. It does not need to be diluted, so it is considered convenient for small areas. In addition, it is best suited for beginners;
  • Pellets – such pellets contain a substance that is active in terms of killing weeds. Some types of pellets are simply poured under the weed and have a slow release, so the exterminator works slowly and very effectively. Other types of pellets need to be diluted with water.

Post-emergent herbicides by weed type

Manufacturers produce different post-emergent herbicides, each suitable for different types of weeds. Some include the most popular weeds, such as crabgrass, dandelions and clovers. Other options include rarer and more difficult weeds such as nut weed, hedgehog and black medic. A third type of post-emergent herbicide is universal, which can list up to 200 weeds. The last option is a noxious and invasive weed killer.

Volume and shape of containers

The amount of product is determined by the treatment area and the number of existing weeds. In modern times you can buy post-emergent herbicide in a bottle of 1 liter to 25 or more. Anything over 25 liters is considered professional and used commercially.

The following are distinguished by the shape of the container:

  1. Glass;
  2. Jar;
  3. Canister;
  4. Bottle;
  5. Barrel;
  6. In spray form.
  7. Choose whatever is most convenient for you.

Addendum

These include additional accessories in the form of a spatula, watering can, measuring cup, and automatic machine for spraying the product. Many manufacturers add additional products to the product: fertilizers, pre-emergents, and more.
