Aztek

Selective pre-emergence herbicide for use contact action in crops of sunflower and maize from the complex of annual weeds.

Active ingredient: acetochlor, 900 g / l

Physical form: emulsion concentrate

Packaging: 20 liters

Characteristics and benefits of herbicide:
High-performance drum herbicide against the first year, primarily of cereal, and many broadleaf (dicot) weeds, applied before planting, along with the planting or emergence of culture to destroy the weeds in pre-emergence period, thereby eliminating them from the fierce competition of young cultivated plants, which in the initial stages of growth and development are particularly susceptible to the harmful effects of weeds. Herbicide activity in soil persists for a long time 6-8 weeks, providing protection of crops during the growing season.
The maximum effect is achieved if the herbicide is brought up to emergence of weeds (sprouted at the time of making the weeds resistant to the drug) on ​​aligned, carefully split the soil surface, which allows you to create a strong protective shield of long-acting, on moist soil, so as soon as the presence of moisture is firmly embedded herbicide in the topsoil and its close contact with sprouts weeds.
It features high photostability, not volatile, not exposed to high temperatures on the clay, as well as vysokogumusovyh soils, due to the absorption of the herbicide, the soil complex, its activity is reduced, offset by increased rates of consumption shows a high selectivity with respect to all protected crops is not a problem of residual quantities of product because the herbicide does not penetrate the surface organs of plants. Has no restriction in the rotation, since the time of harvesting of crops protected by the remnants of the drug in the soil completely mineralized.

The spectrum of the Azteca, 90% KE:

Annual dicotyledons: melkotsvetnaya Galinsoga (Galinsoga parviflora Cav.), Knotweed species (Polygonum spp.), Shepherd's purse ordinary (Capsella bursa pastoris), common Datura (Datura stramonium), Canadian Pikulnik (Conyza canadensis), chickweed (woodlouse) (Stellaria media), Kanatnikov Theophrastus (Abutilon theophrasti Medicus), common lambsquarters (Chenopodium album), lutiga (Lactuca spp.), black nightshade (Solanum nigrum), Portulaca garden (Portulaca oleracea), chamomile (Matricaria spp.), Dymyanka drug (hepatic grass) (Fumaria officinalis), amaranth species (Amarantus spp polynolistnaya Ragweed (Ambrosia artemasifolia).
Perennial weeds: sow-thistle pink Bodyak field (seed germination) (Cirsium arvense), Guma, Sorghum Aleppo (sprouting seed) (Sorghum halepense).
Cereals: foxtail gray (Setaria glauca), green foxtail (Setaria viridis), millet, chicken (Echinochloa crusgalli), crabgrass hemostatic, wild oats, crabgrass (Drosera spp.)

The mechanism of herbicidal action:

The active substance is classified acetochlor chloroacetanilide, mechanism of action is inhibition of cell division. Chloroacetanilide block enzymes that have sulfhydryl groups, causing violations of nitrogen metabolism (protein synthesis). Stops transport of amino acids and auxins in the coleoptile, the osmotic pressure decreases, and the embryo dies. Selectivity depends mainly on the ability of the fetus to absorb the active ingredient, which is absorbed from the soil through the root system of seedlings and young weeds. To moderate the volatility characteristic of the drug, which increases with temperature (above 25 ° C), moderate water solubility and high stability to ultraviolet radiation; weak hydrolysis in neutral and weakly acidic medium.

Directions:

Consumption rate of the solution - 200-400 l / ha

Aztek has no effect on germinating weeds, so if the margin appeared to shoots, it is necessary to carry out machining for their destruction. Pre-sowing cultivation or harrowing, used to seal the herbicide into the soil, successfully destroying the germinating weeds at this time.

The effectiveness of the drug is directly dependent on the presence of moisture in the soil! Optimal conditions for herbicide application - after rain or irrigation rate of 10-20 mm. Drop 5 mmosadkov or irrigation within 7-10 days after the application of herbicide will wash away the Azteca in the zone of germination of weed seeds. Unlike many other herbicides, soil Aztek does not require mandatory clamped by means of cultivation, provided the soil is moist, or in the near future is expected to rain or artificial watering.This condition makes the Aztek most suitable for use in conservation tillage system that preserves the soil structure and moisture.

When dry weather or dry soil for better efficiency of weed control after application of Azteca recommended sealing his cultivator or harrow spring before sowing culture.When drought to enhance herbicidal effects medication necessary to make presowing cultivation to a depth of 5 cm in the presence of soil crust can be applied in the direction of rotary harrows furrows, which contributes to the germination of sunflower. If the drug is made after planting, after the termination of herbicide necessary to kotkovanie harrows for soil compaction.

On crops, weedy perennial weeds (weed, couch grass, bindweed, milkweed, Guma, cane, etc.) are encouraged to apply herbicides glyphosate group as the regrowth of weeds after the harvest of early precursors in the season prior to planting sunflowers.

Shelf life: 3 years. Store at temperatures from -15 C to 40 C.
