Instructions for use of the herbicide Stomp and mechanism of action

Among the effective drugs that help clear beds of weeds is Stomp, a broad-spectrum herbicide produced by the German company BASF. It has a long-lasting effect and is resistant to UV rays; after application, the soil in the beds does not require loosening. An additional plus is the ability to destroy insects.

Composition and release form of the herbicide Stomp

There are two types of the product:

1. 33% emulsion concentrate (EC) 330 EC (contains 330 g/l pendimethalin). At the moment, the tool is not used, since the license expired in 2017.
2. 45.5% microencapsulated suspension Professional (455 g/l pendimethalin). More effective than CE, the license is valid until 2022 (possibly an extension).

All recommendations presented apply specifically to Professionals.

Advantages and disadvantages

The benefits of the herbicide include:

1. It destroys weeds well in “weekend gardens” - relatively well-groomed but irregularly cultivated areas.
2. Belongs to the third class of danger, harmless to people and bees.
3. Fights against various types of weed annuals.
4. A single treatment is sufficient.
5. Almost completely decomposes in the soil; various types of crops can be planted on the treated area.
6. Able to fight not only weeds, but also insect pests.
7. Long-lasting, so weeding will no longer be necessary.

However, the drug Stomp also has disadvantages:

1. It will not help if the area is new, very overgrown or has not been cultivated for a long time. It is powerless against the abundance of wheatgrass and quinoa.
2. The best effect is achieved on light soils enriched with humus. Does not work on peat, gley, silty soils, floodplain meadows.
3. Sensitive to weather conditions: precipitation will help destroy all weeds; without it, the effectiveness will be reduced.

How does the drug remove weeds?

The active ingredient is pendimethalin, the features of which are as follows:

1. The next 14 days after treatment, the substance is distributed over the soil layer in which the weed seeds are located.
2. When weeds germinate, active work begins; the drug penetrates into plant seedlings, preventing DNA synthesis.
3. The cells lose their ability to divide, causing the seedling to die.

Important! If weed seedlings already exist, treatment with Stomp should be carried out until the development of two true leaves (for dicotyledons) or the first pair of leaves (for cereals).
