Magnum weed killer: instructions for use, reviews

Magnum herbicide is a systemic preparation of selective action used to destroy annual and some types of perennial weeds in fiber flax and grain crops. The high efficiency of the chemical makes it advisable to use it to clear virgin lands and non-agricultural areas from unwanted vegetation.

To destroy weeds in a grain field, a single application of Magnum herbicide is sufficient.

Composition and release form

The active ingredient of Magnum herbicide is metsulfuron-methyl, which belongs to the class of sulfonylureas. The content of the active component in the finished product is 60%.

Manufacturers of pesticides offer farmers another herbicide called Magnum Super, which contains metsulfin-methyl (30%) and tribenuron-methyl (45%).

The drug is produced in the form of water-soluble granules, packaged in 100 g plastic bottles.

The manufacturer of Magnum and Magnum Super is the August company.

The herbicide is produced in easy-to-use packaging

Operating principle

Penetrating through foliage and roots into plant cells, the active component of the herbicide Magnum VDG suppresses the formation of substances necessary for DNA biosynthesis and stops cell division.

Under the influence of the drug:

• the growth of green mass of plants and the development of the root system stops;
• flower buds do not open;
• the above-ground parts of the weeds acquire an anthocyanin tint, that is, they become pink-red;
• the veins on the leaves become discolored;
• the tops of the weeds dry out;
• the development of chlorosis and tissue necrosis is observed.

The first results of the herbicide can be seen a couple of days after treatment, and the complete death of weeds occurs within 1-3 weeks.

Magnum herbicide is effective throughout the entire growing season of cultivated plants.

Contact of herbicide with vegetable crops will lead to their death
