AM PATRIOT SU
A new hybrid of the selection of "AF NPP AGROMYR" LLC, submitted to the State variety testing in 2023.
- Grandstar resistant. Resistant to
herbicides, which contain tribenuron - methyl (SU) - SUMO technology with an application rate of 50 grams per 1 ha.
During the tests, we used the following schemes of application of insurance herbicides:
1. Granstar (with adhesive) with a one-time dose of 50 grams per 1 ha.
2. Two-time application of granstar (with an adhesive) at the rate of 40 grams per 1 ha, and the duration between applications is 10 days.
3. ARROW herbicide with the active substance cletadim, then, after a week, granstar is applied at the rate of 45 grams per 1 ha. The rate of use of anti-cereal herbicide depends on the phase of sunflower development and the type of cereal weeds (annual or perennial). Also, the choice between which drug to apply earlier depends on which weed is more harmful to sunflower at the first application.
4. Granstar (with adhesive) with a one-time dose of 35 grams per 1 ha; and after 14 days of application of Helianteks (with adhesive) - against ragweed and weeds at the rate of 45 grams per 1 ha.
The selection of the number of applications depends on the field's clogging. As a rule, once is enough. But in the case of weed emergence at the same time as the emergence of
sunflower, you need to plan to apply the drug twice, since the herbicide has only a contact effect, that is, it destroys only sprouted weeds.
Biological and approbation characteristics:
Hybrid AM PATRIOT SU mid-early. Vegetation period - 112-115 days.
The height of the plants is 170-175 cm.
The oil content is 52-53%.
The basket is medium-sized. From the side of the seed mass, it has a convex shape. A peculiarity of the hybrid is a small angle (30-35 degrees) of the inclination of the basket during ripening, which allows water to drain from the cup of the basket. This feature of the hybrid allows it to be less affected by gray and white rot than other hybrids.
Seeds of medium size, black in color, with barely noticeable gray stripes.
