Tifi herbicide: instructions for use, mechanism of action, consumption rates, analogues

"Tifi" post-emergence herbicide, which is actively used in wheat and corn fields. Its solution destroys broad-leaved weeds. It is a systemic pesticide with a selective effect. It has a high selectivity for corn.

Composition, form of release and purpose of the drug "Tifi"

"Tifi" is a sulfonylurea herbicide. The solution of the drug destroys dicotyledonous weeds (annual varieties) that clog barley, wheat, soybean, corn fields.

It is effective against the listed weeds:

• black nightshade;
• Snake Highlander;
• shiritsa (upturned, zhminovidnaya);
• field mustard;
• highlander (rough, serpentine, kidney, bindweed);
• green, white gauze;
• garden purslane;
• Theophrastus cable car.

The active ingredient is thifensulfuron-methyl. In Tifi, its concentration is 750 g/kg. The drug is produced in the form of VDG - water-dispersible granules. Packing:

• 100g bottle;
• box of 100 bottles.

Mechanism of action of the remedy

Aqueous solution of the herbicide "Tifi" getting on the surface of the leaves, penetrates into the tissue. With plant juices, the active substance of the herbicide enters the growth zones (stems, roots). Tifensulfuron-methyl inhibits the production of an enzyme (acellolactate synthase).

After a few hours, the drug begins to act, it inhibits cell division and growth. On the 3-7th day, external symptoms appear in the form of:

• chlorosis;
• tissue necrosis;
• dying off points of growth.

By the end of the 2nd or 3rd week, the weeds treated with the Tifi solution die.

Pros and cons of herbicide

The remedy for broad-leaved weeds is effective. After spraying, its action begins after a few hours. Tifensulfuron-methyl is rapidly degraded in corn tissue. Herbicide-treated fields increase yields.

When testing "Tifi" in the corn fields of the Krasnodar Territory, the number of weeds decreased by 88%, the weight by 93%. The addition of "Mix G" increases the effectiveness of treatments to 92% and 97%.

The disadvantage of the herbicide "Tifi" is the resistance of weeds to sulfonylurea drugs. Addiction occurs with prolonged use of drugs with the same mechanism of action.

Consumption rate for different plants

Specialists have developed their own regulations for each crop. It indicates the rate, method of application, waiting time, number of applications per season. Approximate protective exposure time is 8-10 weeks.

Methods for preparing a working solution

First prepare the stock solution. The capacity of the sprayer determines its quantity. The rate of herbicide is poured into a bucket, a quarter filled with water. After thorough mixing, water is added - ¾ volume.

Sprayer capacity is filled according to the scheme:

1. Fill ½ volume with water.
2. Introduce mother liquor.
3. Add water.

The mixture of "Teefee" and water is constantly stirred with a stirrer. The principle of preparing tank mixtures is the same. The concentrates are not mixed, they are added to the working tank of the sprayer one by one. Surfactants are injected last.

Teefi working solution is consumed immediately.

Safety precautions for use

During the operation of the sprayer, the wind speed is not higher than 4 m / s, the air temperature is within 25 ° C. Crops are processed in the evening or in the morning. In drought, heat, mineral fertilizers should not be added to the working mixture. Due to low toxicity, the drug is not prohibited from being used in water protection zones.

Toxicity

For mammals, humans, bees "Tiffy" is not dangerous enough. Hazard class III has been assigned to it.

• Octapon;
• Banwell.

How to store properly

Analogues

The drug has analogues for the active substance. Suspension "Allert", STS destroy annual dicotyledonous weeds in the fields with soybeans, flax, corn.

Surfactants are added to the working solution of the imported herbicide "Allert" - BIT 90, F.

Aton, VDG are produced in the form of granules. It has a wide range of activities. They destroy dicotyledonous weeds in corn fields. "Aton" is added to tank mixtures. The drug has many advantages:

• low consumption rate;
• simple application;
• practical packaging.

Other analogues produced in the form of VDG: Alfa-Guard, Shansti, Blend.
