Tolazin - combined herbicide against weeds in sunflower, corn, soybean crops, Kyiv region region.

Tolasin - combined soil and post-emergence herbicide of systemic action with increased concentration of active substances.

Active substances: S-metolachlor 468 g/l; terbuthylazine - 281 g/l
Preparative form: Suspension emulsion
Object of action: annual dicotyledonous and grass weeds

The container is 20 liters, the price is for 1 liter.

Application temperatures are permissible +5...25°С, optimal +10...+25°С

Advantages of Tolazin:
Lower rate of application with the help of increased concentration of active substances (saving money in logistics); A wide range of control of annual weed species; The period of protective action is 6-8 weeks;
restrains the appearance of a new wave of weeds due to the soil action of the drug;
Flexibility in application - the possibility of use on corn both before germination and in the phase of 3-5 leavescorn; The drug has a mild effect on the culture if the recommendations are followed;
Possibility of application on parental forms of corn;
Does not affect crops in crop rotation;

Mechanism of action of Tolazin:
Tolazine is a systemic herbicide;
inhibitor of biosynthesis and photosynthesis processes.
Terbuthylazine, an inhibitor of photosynthesis, is absorbed both by the roots (when applied to the soil) and by the leaves of weeds (when applied after emergence). Moving through the xylem of the plant, it blocks the process of photosynthesis, as a result of which sensitive weeds turn yellow and die.
S-metolachlor - an inhibitor of the biosynthesis of lipids and fatty acids - acts at the stage of weed germination, disrupting the processes of cell division and blocking the initial stages of mitosis.(//tractor-service.com)
As a result, weeds die at the moment of germination. When applied during growing season, the herbicide is absorbed by the seedlings (especially the coleoptile) and partly by the root system, moves through the plant, which leads to the death of weeds.

Regulations Application of the herbicide Tolazin: Culture Target object Phase of drug application Rates of drug consumption, l/ha Official registration

Sunflower
Annual cereal and dicotyledonous weeds. Spraying the soil before the emergence of crop seedlings 2.0-3.0

Corn
Annual grass and dicotyledonous weeds. Spraying the soil to the seedlings of the crop or from 3 to 5 leaves in the crop 2.0-3.0

The practice of using drugs with a similar active ingredient

Soy*
One-year cereal and dicotyledonous weeds Spraying the soil before the emergence of crop seedlings 2.0-3.0

Potato
One-year grass and dicotyledonous weeds. Spraying the soil before the emergence of crop seedlings 2.0-3.0 *when applying on light (low-moss) soils, it is recommended to reduce the application rate of the drug to 2.0 l/ha.

Recommendations for use The treatment technology with pre-sowing earnings of the drug is advisable to be carried out when dry weather or the threat of wind erosion is expected. The consumption rate of the working solution in the profitable period is 250-400 l/ha. After the appearance of seedlings, the drug can be used on corn in the phase of 3-5 leaves with a rate of consumption of the working solution of 200-300 l/ha. An important point in post-emergence application is the phase of weed development. At the time of application of the herbicide, annual grass weeds should be in phase 1-2 leaves, annual dicotyledons - from the cotyledon phase to phase 2 true leaves. If, during profitable use of the drug, slight precipitation fell after processing or during processing, the effectiveness of the drug does not decrease. Using the drug in adverse weather conditions (frost, high air temperature, drought) reduces its effectiveness.
Recommended tank mixtures Tolazin 2.5-3.0 l/ha + Dilar 0.12 kg/ha - preemergence on corn for extended protection against sunflower blight Tolazin 1.7-2.3 l/ha + Dilar 0.12-0.15 kg/ha - on corn in the 3-5 leaf phase for extended protection against sunflower blight and thistle the situation shown in the photo, we recommend the use of a tank mixture: Tolazin 1.7-2.3 l/ha + Dilar 0.12-0.15 kg/ha - will allow one application to control annual grass and dicotyledonous weeds and destroy vegetative thistle plants.
Since Dilar has a powerful rooting action, it will clear the field of thistles for the next crops in the crop rotation.
The effect of water pH on the effectiveness of Tolazine Acidic (5.0-6.0) Neutral (6.0-7.0) Alkaline (7.0-8.0) good good tolerable* *in the case of an alkaline reaction of water or a working solution, the working solution should be used as soon as possible to avoid alkaline hydrolysis of the active substances.
