Best Weed Killers Types

Such products are divided into three types of residual, contact, and systemic.

Residual Weed Killers

This species prevents seed germination and photosynthesis. This prevents the growth of weeds. Means remain in the ground for a long time, so you should know that in this area you cannot plant edible plants and flowers, because they do not germinate due to the range of the means. Such products are best used for alleys, sidewalks, patios and other hard surfaces. Be extremely careful not to spray them near lawns or shrubs.

Contact Weed Killer

Using such an agent means destroying the plants that are in contact with it. Usually such products have a fast action and a long lasting effect. Such means you can handle all the plants that spoil the appearance of your lawn or other territory by this type of the weed killer.

Contact herbicide has two subspecies: elective and non-selective.

• Selective weed killer for lawns is used for certain types of wild grass. This means that if you spray it on the entire lawn, it will only fight against those plant species for which it is intended. So, it is the best weed killer for lawns which are established.
• The non-selective weed killer will fight against all the plants on which you spray it. It does not matter whether it is a normal flower or a wild grass that needs to be destroyed. When using such agents be careful and do not spray them on the plants that you want to save. Non-selective killers are especially good for annual weeds; they do not destroy the roots but make the plants weak. If you want destroy perennial weeds, you will need to use them several times.

Systemic Weed Killer

System agents combine contact and residuals and fight with the roots and the plants themselves. The principle of their work is to reduce protein and chlorophyll. In this case, you have to wait for the effect to 2 weeks.

Such concentrates are perfect for using on lawns, because they do not destroy the structure of the grass. They do not poison the ground, so you can plant other plants on it after.

Tips For Using best weed killer

• Do not apply such agents at high temperatures;
• Do not treat very young grass, wait 4 to 5 months, even if the packaging indicates otherwise;
• Be sure to look at the weather forecast so that it does not rain because it can wash away the agent;
• If the temperature is too high, water the lawn the day before the treatment;
• Do not mow the lawn a few days before use.
