Description and physical and chemical properties
"Dual Gold" - a highly effective herbicide, used mainly on vegetable and industrial crops. The main chemical component of this drug is the substance S-metolachlor, at a concentration of 950 g per liter of water.
Metolachlor used in the preparation is a mixture of two diastereomers in a 1: 1 ratio. The researchers found that one of the diastereomers is more active than the second (more than 15 times).
This made it possible to successfully resynthesize metolachlor with a 9: 1 ratio,with the predominance of a more active component, which allowed to produce a new superactive active ingredient of the herbicide "Dual Gold" - S-metolachlor.
This is crucial in achieving a unique efficacy of the drug, which distinguishes the agent from its predecessor. 
The drug comes in the form of a concentrated emulsion. "Dual Gold" is a systemic substance of selective action and is introduced into the soil before the emergence of plants. The drug is soluble in water - 490 mg / l at a temperature of 25 ° C. The half-life of the product in soil with an acidity level of pH 6.8 takes 27 days.
The range of action of the herbicide "Dual Gold"
In the period of early development, crops need special attention, during this period the plants are dangerous and there is great competition with weeds for moisture, food and light. The mechanism of action of the drug "Dual Gold" lies precisely in the fact that it blocks the process of growing weeds.
Herbicide penetrates through kleoptil weed (these are the very first sheets of cereals, not having a leaf blade and having the appearance of a tubule),which under the influence of the drug twists and dies. In the weeds of the class of dicotyledonous herbicide enters through the cotyledons, after which the weed dies.
The drug acts in such a way that the destruction of weeds occurs in the period of their germination - before the emergence of crops. 
Drug benefits
The preparation "Dual Gold" has an important advantage over other herbicides precisely by providing protection from weeds of cultivated plants for up to two months. Another great advantage of the drug is its non-toxicity.
There are no restrictions on crop sowing in the following year after processing. The use of outdated herbicides several times in a row by an order reduces the future crop yield.
The drug has a very low volatility compared with other means. For this reason, "Dual Gold" is applied directionally, which allows you to avoid reducing the effectiveness due to evaporation of the drug.This distinguishes it from volatile herbicides, which are usually embedded deep in the ground.
Shallow embedding in the soil - at least by 3-4 cm - will significantly enhance the effect of Dual Gold.
In a dry climate, which prevails in some regions, small embedding of the drug in the ground (2-3 cm) is a guarantee of its action.
Instructions for use: preparation of the solution and the rate of application
Before starting work with the preparation, it is recommended to check the tank, hoses, piping, nozzles for spraying the solution, as well as other details of the spray device. You also need to check the tip, so he evenly sprayed the treated area.
It is necessary to spray early in the morning or late in the evening in the conditions of lack of wind. Such conditions are chosen so that the drug does not get on the plants that grow nearby. After processing the area, be sure to rinse the spray tank and all parts.
Method of preparation of the solution: initially in the tank for spraying make a pre-calculated amount of "Dual Gold". Then gradually add water until the tank is full. At the same time it is necessary to mix in order that the solution was homogeneous.
The finished solution is recommended to use only on the day of preparation. If you need to add any other products to the preparation, then another solution should be prepared according to the instructions in a separate container and then added to Dual Gold, while stirring intensively.
Let's take a look at how to prepare a working solution for a different type of crop and when to process the plants. 
When using the herbicide for white cabbage in seedlings, it is sprayed on the 3-10th day after transplanting into the ground. Spray once. The consumption rate of the substance - from 1.3 to 1.6 liters per hectare. From this norm, a working solution is prepared with a calculation from 200 to 400 liters per hectare.
When processing the white cabbage planting herbicide consumption from 200 to 400 liters per hectare. Treated soil after sowing before sprouting cabbage.
When spraying sunflower, soybeans, corn and spring rapeseed use such a rate - from 1.3 liters to 1.6 liters per hectare. Spray need to sow crops in the ground or before germination.Under drought conditions, a herbicide will be more effective under conditions of shallow embedding at a depth of 5 cm.
In order to process the sugar and table beets, you need to use "Dual Gold" in a concentration of 1.3-1.6 liters per hectare for spraying sowing, as well as before germination. The prepared solution is consumed in the amount of 200-400 liters per hectare. For spraying the soil before planting or before the emergence of sugar and table beet, it is necessary to use a concentration of 1.6-2.0 liters of a substance per hectare.
For the use of herbicide for the treatment of pumpkins, the use of Dual Gold at a concentration of 2 liters per hectare is used. 
Impact speed and period of protective action
The duration of the protective effect of eight to ten weeks - is one of the main advantages of the herbicide. Long protective action provides high efficiency of a preparation throughout the entire period of vegetation. It also prevents late weed infestation of the field and ensures the suppression of weeds of the second wave.
After the vegetation period, the tool is completely dissolved in the soil, which solves the problem of the residual amount of herbicide and allows you to quickly produce subsequent planting of crops.
After exposure to the drug it is forbidden to cultivate the soil for seven days, as this may lead to the termination of the action of the herbicide.
Compatibility with other drugs
Herbicide "Dual Gold" is recommended to use in a mixture with other means in the fight against dicotyledonous weeds, as this will expand the range of impact.
It should be remembered that in any case, you need to check in advance mixed drugs for compatibility.
Precautionary measures
Even taking into account the weak toxicity of the herbicide, work with it should be carried out with strict adherence to precautions. It is necessary to avoid contact with open skin of the working mixture during its preparation, it is also dangerous for the herbicide to hit the mucous membranes.
To work with the drug, use protective clothing, special glasses and a respirator. If contact has occurred with the working solution, immediately rinse the place of contact under running water. Wash hands thoroughly after handling.
Term and storage conditions
The manufacturer recommends storing "Dual Gold" in a dry place without access of sunlight at a temperature from -5 ° C to +35 ° C. Keep as far away as possible from food and medicine. The shelf life of the herbicide is 4 years from the date of manufacture.
