Composition, release form and purpose of the drug "Tifi"
Tifi is a sulfonylurea herbicide. With a solution of the drug, dicotyledonous weeds (annual varieties) that infest barley, wheat, soybean, and corn fields are destroyed.
It is effective against the weeds listed:
- nightshade black;
- serpentine mountaineer;
- squid (thrown back, puck-shaped);
- field mustard;
- highlander (rough, serpentine, pochuy, bindweed);
- green, white gauze;
- garden purslane;
- cable car Theophrastus.
The active ingredient is thifensulfuron-methyl. In "Tifi" its concentration is 750 g / kg. The drug is produced in the form of WDG - water-dispersible granules. Packaging:
- 100 g bottle;
- box for 100 bottles.
The mechanism of action of the agent
An aqueous solution of the herbicide "Tifi", getting on the surface of the leaves, penetrates into the tissues. With plant juices, the active substance of the herbicide enters the growth zones (stems, roots). Thifensulfuron-methyl inhibits the production of an enzyme (aceolactate synthase).
After a few hours, the drug begins to act, it inhibits cell division and growth. On the 3rd-7th day, external symptoms appear in the form of:
- chlorosis;
- tissue necrosis;
- dying off of growth points.
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 broadleaf weeds is effective. After spraying, its effect begins after a few hours. Thifensulfuron-methyl is rapidly degraded in corn tissue. In fields treated with herbicide, yields are increased.
When testing "Tifi" in the corn fields of the Krasnodar Territory, the number of weeds decreased by 88%, weight by 93%. The addition of "Mix Zh" increases the efficiency of treatments up 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
For each culture, specialists have developed their own regulations. It indicates the rate, method of application, waiting times, the number of applications per season.The approximate time of protective action is 8-10 weeks.
| Culture | Weed | Processing method | Phase | Dose (l / ha) | Specificity
| Seasonal treatments | Action time (day) | Consumption (l / ha) |
| Wheat (winter) | Dicotyledons, annuals | Spraying | Spring, tillering phase | 0,015 | Add 200 md / ha "Mix Zh" | 1 | 60 | 200-300 |

Working solution preparation methods
First, a mother liquor is prepared. The sprayer capacity determines the quantity. The rate of the herbicide is poured into a bucket, a quarter filled with water. After thorough mixing, add water - ¾ volume.
The capacity of the sprayer is filled according to the scheme:
- Fill ½ the volume with water.
- The mother liquor is introduced.
- Add water.
The mixture of "Tifi" and water is constantly stirred with a stirrer. The principle of preparing tank mixes is the same. The concentrates are not mixed, they are added to the working container of the sprayer one by one. Surfactants are introduced last.
Working solution "Tifi" is consumed immediately.
Safety measures during 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 treated in the evening or in the morning. In drought, heat, mineral fertilizers cannot be added to the working mixture. Due to its low toxicity, the drug is not prohibited to be used in water protection zones.
Toxicity degree
For mammals animals, humans, bees "Tifi" is not very dangerous. He was assigned the III hazard class.
| An object | Toxicity |
| Birds | Low |
| Fish | |
| Bees | |
| Ground water | |
| Open reservoirs |
Compatibility of the herbicide with other products
Organophosphate insecticides must not be mixed with Tifi. The interval between treatments is 10 days. The active ingredient thifensulfuron-methyl is compatible with carbamate insecticides and herbicides:
- "Super";
- Dialen;
- "Octapon";
- Banvel.
How to store it correctly
The drug can be stored in a warehouse equipped for 3 years.
Analogs
The drug has analogues in terms of the active substance. Suspension "Allert", STS destroy annual dicotyledonous weeds in fields with soybeans, flax, corn.
Surfactants - BIT 90, Zh. Are added to the working solution of the imported herbicide "Allert".
In the form of granules produced "Aton", VDG. It has a wide range of effects. They destroy dicotyledonous weeds in corn fields. "Aton" is added to tank mixes. The drug has many advantages:
- low consumption rate;
- simple application;
- practical packaging.
Other analogs produced in the form of VDG: Alfa-Guard, Shansti, Kupazh.
