Harnes — a highly effective soil herbicide.
A selective pre-emergent herbicide for controlling annual, monocotyledonous and dicotyledonous weeds in 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 provides weed-free conditions for 12–16 weeks, creating favorable conditions for crop growth. As a result — larger, healthier plants and higher yields.
Application timing
Harnes should be applied before weed and sunflower emergence:
before sowing;
immediately after sowing.
Incorporate Harnes into the soil if the soil is dry.
Application rates
Harnes is registered for use on sunflower, at a rate of 1.5 to 2.0 L/ha.
Working solution application rate
200–300 L/ha.
Harnes does not affect emerged weeds, so if weeds have already emerged, mechanical control is necessary for their destruction. Pre-sowing cultivation or harrowing, used for incorporating Harnes into the soil, effectively eliminates weeds that have emerged by this time.
Harnes breaks down in the soil within one growing season and does not affect subsequent crops in crop rotation.
Incorporation into soil
Unlike many other soil herbicides, Harnes does not require mandatory incorporation using cultivation, provided the soil is moist or rain or irrigation is expected soon. This condition makes Harnes the most suitable for use in soil conservation tillage systems, which help preserve soil structure and productive moisture. If the herbicide is applied to dry soil and no rain or irrigation is expected soon, 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 sunflower sowing, then immediately after sowing apply Harnes.
5 mm of rainfall or irrigation within 7–10 days after application will move the herbicide into the germination zone of weed seeds.
In dry weather or dry soil, to enhance weed control after Harnes application, it is recommended to incorporate it using a cultivator or spring-tooth harrow before crop sowing. If a soil crust is present, rotary hoes can be used in the furrow direction to aid 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 regrow after harvesting early-season predecessors prior to sunflower sowing.
