Harnes — a highly effective soil herbicide.
Selective pre-emergent herbicide for controlling annual broadleaf and grassy weeds in crops of cabbage, soybean, corn, sugar beet, sunflower, onion, citrus, fruit crops, and vineyards.
Active ingredient
acetochlor, 900 g/l
Formulation
concentrate emulsion
Base unit
20 l.
Mode of action
After application, Harnes remains in the topsoil layer and is absorbed by emerging weed shoots and roots.
When used according to instructions, Harnes ensures weed-free conditions for 12–16 weeks, creating favorable conditions for vigorous crop growth. As a result — larger, healthier plants and higher yields.
Application timing
Apply Harnes before weed and sunflower emergence:
before planting;
immediately after planting.
Incorporate Harnes into the soil if the ground is dry.
Application rates
Harnes is registered for use on sunflower with application rates from 1.5 to 2.0 l/ha.
Working solution rate
200–300 l/ha.
Harnes does not affect emerged weeds, so if weeds have already germinated, mechanical cultivation is required to remove them. Pre-planting cultivation or harrowing, used to incorporate Harnes into the soil, effectively eliminates weeds that have emerged by this time.
Harnes degrades in the soil within one growing season and does not affect subsequent crops in crop rotation.
Soil incorporation of Harnes
Unlike many other soil herbicides, Harnes does not require mandatory incorporation via cultivation, provided the soil is moist or rain or irrigation is expected within the next time frame. This condition makes Harnes most suitable for use in soil conservation tillage systems, promoting soil structure and productive moisture retention. If the herbicide is applied to dry soil and no rain or irrigation is expected in the near future, the product must be incorporated into the soil.
Compatibility with fertilizers
The herbicide Harnes can be mixed and applied with any liquid mineral fertilizers (LMF).
Application
For optimal effect, prepare the soil 3 days before planting sunflower, then immediately after planting apply Harnes.
5 mm of rainfall or irrigation within 7–10 days after application will move the herbicide into the seedling emergence zone.
In dry weather or dry soil, for better weed control after Harnes application, it is recommended to incorporate it using a cultivator or spring harrow before planting. If there is a soil crust, rotary hoes can be used in the furrow direction to promote sunflower emergence.
On fields heavily infested with perennial weeds (dandelion, crabgrass, bindweed, milkweed, goosegrass, reed and others), it is recommended to apply Roundup as weeds emerge after harvesting early-season predecessors prior to sunflower planting.
