Composition and form of release

The grader is a concentrated solution. The herbicide is sold in bottles with a capacity of 1 liter, as well as canisters of 5,10 liters. The active ingredient of the drug is imazapyr with a concentration of 250 g per liter.

Mechanism of action

After spraying, the herbicide is quickly absorbed by weed leaves and spreads to all parts of plants, including the root system. Imazapir inhibits the synthesis of the enzyme acetohydroxy acid, which leads to DNA damage. The active substance moves along the phloem, xylem and concentrates at growth points, stopping the process of cell division.

Grader herbicide also exhibits soil activity, so it is also effective against young weeds. The destructive effect of the drug on non-agricultural lands lasts 3-5 years, depending on the composition of the soil.

The drug begins to work two hours after treatment. After a day, it stops the growth of weeds. After 7-14 days, there are clear signs of herbicide action.

Among them:

• chlorosis;
• yellowing of leaves;
• dejected look.

Fully herbaceous weeds die a month after the Grader treatment. And tree and shrub growth – after 8-12 weeks.
