Herbicide Basis: instructions for use, safety measures and analogues

Basis is a two-component herbicide that is used for post-emergence treatment of a corn field. The drug destroys all weeds that take away nutrients from the main crop. Basis acts selectively and systematically. The drug does not harm corn and humans, its active substances are not found in the tissues of the main crop.

Composition, purpose and dosage form of the drug Basis

This is a two-component herbicide that kills grasses and broadleaf weeds in corn crops. Produced at Russian production facilities owned by the American company DuPont.

This drug contains active substances from the sulfonylurea class - rimsulfuron and thifensulfuron-methyl. The herbicidal agent has systemic and selective activity. Destroys ragweed, amaranth, shepherd's purse, couch grass, thistle, sow thistle and other weeds. The drug is in the form of a dry fluid suspension. Sold in 100g plastic jars.

How does the herbicide work?

Basis dissolves in water at the dosage indicated in the instructions. Herbicide mixture is irrigated in corn fields at the beginning of plant growth.

The drug has selective activity, therefore it acts only on weeds.

Active substances penetrate into weeds through leaves and roots. Distributed throughout the organs, the herbicide acts on the enzyme necessary for the synthesis of essential amino acids.

In just a couple of hours, the treated weeds stop growing, gradually begin to wither. The first signs of wilting (chlorosis, necrosis) can be seen after 3-5 days. Completely die in 2-3 weeks.

Pros of using

Advantages of herbicide Basis:

quick and long-lasting weed control:
can be used for preventive purposes;
used during any period of weed vegetation;
has systemic and selective activity;
one treatment is enough.

Drug consumption rate

The herbicidal agent is used in the following dosages (at the flow rate of the working fluid - 200-300 l/ha):

For the destruction of annual cereals and dicots: 20 g/ha.
For the destruction of perennial grasses and dicots: 25 g/ha.

Preparing the working tool

Fine sprayers are used to irrigate the corn field.First, a matrix solution is prepared in a plastic bucket. Then fill the sprayer tank halfway with clean water. With the stirrer on, the matrix mixture is added. The stirrer is turned off and the required amount of liquid is poured into the tank. The herbicide mixture is prepared on the day the cornfield is irrigated.

How to use ready-made solution

Prepare the solution according to the proportions specified in the instructions on the day of irrigation of the corn field. Herbicide should not be used on weeds that are wet from dew or rain. The basis is undesirable to apply if the main crop (corn) is under stress due to drought, lack of nutrients, diseases, insects. The herbicide is used on crops of corn, which is grown for grain or silage, only once per season.

On the night before irrigation, make sure that the thermometer does not fall below 10 degrees Celsius. It is not recommended to cultivate a corn field if the daytime temperature has risen above 25 degrees Celsius. Basis herbicide is used when corn has 2-5 leaves.

Weeds are vulnerable at the earliest stage of their development (in the phase of 1-4 leaves). Basis is always recommended to be used with Trend 90 surfactant. This agent improves the wetting of weeds with a herbicide solution.

Precautions

The person involved in the preparation of the herbicidal solution must observe the precautionary rules. Work with this chemical should be in a protective suit, respirator or mask, rubber boots and gloves. It is forbidden to inhale vapors and drink the solution.

After field work, wash your hands and face with warm water and soap, rinse your mouth with baking soda.

Toxicity

Basis belongs to the 3rd class of toxicity. The herbicide is harmless to humans and animals. It is not recommended to cultivate the field during the summer of bees. The product is non-toxic to beneficial soil insects.In the soil, active substances decompose within a month. The herbicide is safer to apply on acidic soil. On alkaline soil, the chemical degradation of Basis components is difficult.

Compatibility

Herbicide Basis can be used in conjunction with other herbicidal preparations for the complex destruction of weeds. When using several herbicides together, the dosage is reduced. Basis can be used in conjunction with fungicides and insecticides.

True, this herbicide is not allowed to be used with organophosphate insecticidal preparations. Herbicides must not be mixed with foliar fertilizers.

Storage of funds

Basis herbicide can be stored in tightly closed original packaging for 3 years from the date of manufacture.The expiration date is usually indicated on the label. To store this pesticide, you need to take a separate room. It is better to keep the drug in a warehouse, protected from moisture, sunlight.

Herbicide is stored at room temperature. The prepared solution is used at a time. The herbicidal water mixture should not be stored for more than one day, as the activity of the chemicals decreases over time. It is better to calculate the required amount of the drug for dilution before use. After irrigating the field, unused residues are poured outside the agricultural land.

Analogues of the drug

Analogues of the herbicide Basis are preparations Centaur, Batu. These herbicides have exactly the same composition and are used to kill weeds in corn crops. Both of these drugs are dissolved in water before use, in the proportions indicated in the instructions.
