Characteristics

Active ingredient content

Imazamox, 33 g/l + Imazapyr, 15 g/l

Chemical group

imidazolinones

Formulation

soluble concentrate

WHO classification

Class III (moderately hazardous)

Recommendations for use

Application features

Impreza should be applied only on IMI-tolerant sunflower hybrids at the early stages of weed development. It is not recommended to apply the product when sunflower plants are under stress from environmental factors (low or, conversely, high temperatures, severe drought, excessive moisture, etc.). It is not recommended to apply this herbicide at temperatures below +10°C and above +25°C, or when the difference between night and day temperatures exceeds +15°C. The optimum application temperature is from +14°C to +25°C.

Working solution consumption rate

200-300 l/ha. If there is a large amount of plant residue on the soil, the working solution rate should be at least 250 l/ha. The product is most effective when most weeds are at the early stages of development.

Compatibility

It is not recommended to apply in a tank mix with other pesticides and micronutrient fertilisers

Working solution pH requirements

from 5 to 8

Application precautions

In some cases, a reduction in height and/or a change in colour is observed after application. As a rule, plants regain their normal appearance and height within 1–2 weeks.

Mechanism of action

Imazamox and imazapyr are absorbed by the plant and spread through the roots and leaf surface; the a.i. move through the xylem and phloem and accumulate in the growing points. In weeds, the active ingredients inhibit the enzyme acetohydroxyacid synthase (ALS), which is responsible for the formation of the amino acids (valine, leucine and isoleucine). This disrupts protein synthesis, which leads to disruption of DNA synthesis and slower growth of plant cells, resulting in weed death.

Crop rotation planning

Products of the imidazolinone group must not be used on the same field more often than once every three years. After applying the product, the following crop rotation should be observed:
– no restrictions – sunflower and rapeseed varieties or hybrids resistant to imidazolinone-group herbicides
– after 4 months – winter wheat, rye
– after 9 months** – corn, barley***, oats, rice, sunflower, soybean, pea, beans, sorghum
– after 18 months – vegetables, potato
– after 24 months – sugar and fodder beet, rapeseed, buckwheat, millet.
** If soil pH is above 6.2 and total precipitation is more than 200 mm.
*** With total precipitation of less than 200 mm and pH 6.2, there is a risk of phytotoxicity.
