The real scourge of sugar beet crops are weeds, such as sow thistle, corn, Teofrasta's hot rod, various species of mountaineers and others. They take from the soil two times more minerals than a healthy root vegetable. Naturally, this leads to lower yields. One of the most effective means to combat dicotyledonous weeds, even if the field is thoroughly littered with them, is the Caribou herbicide, which has a wide spectrum of action.
Active ingredients
As the active substance in this preparation is used triflusulfuron-methyl, the content of which is 500 g per kilogram of the herbicide. This substance belongs to the class of sulfonylureas.
Did you know? Copper sulfate is considered to be the first herbicide of selective action in the world. - In the 19th century, scientists noticed the ability of this compound to inhibit the growth of dicotyledonous weeds.
Release form, packaging
The herbicide is supplied to the market in an airtight foil package containing ten 60-gram sachets of the drug. In such packaging, if not to violate its tightness, it retains its properties for three years. Sachets from the package do not need to open when using the drug, they are soluble in water. Herbicide itself available as wettable powder.
For the treatment of sugar beet is often used tank mix, adding other herbicides, such as "Lontrel" or "Dual Gold", insecticides, fungicides and mineral fertilizers.
Herbicide Benefits
This drug has a number of undeniable advantages, in particular:
- starts to act very quickly;
- Herbicide is highly selective for beets;
- it is applied in the wide range of temperatures;
- its use allows to reduce the use of other herbicides;
- does not limit crop rotation;
- it can be effectively used in dry weather;
- There are no restrictions on the use near water bodies.
Did you know? Approximately 4.5 million tons of various herbicides are used worldwide annually.
Operating principle
The drug is mainly absorbed by the leaves of weeds, to a lesser extent - their roots. When assimilating it blocks cell division of weed plantsthus stopping their growth after only a few hours. Subsequently, weeds acquire anthocyanin coloration (red, violet, blue), then chlorosis is observed in them and as a result they die. The whole process usually takes 10-15 days.
Caribou is most effective. at a phase of development of weeds to 2 leaves inclusive. For some species (sunflower cod, mustard field) the threshold of greatest efficiency rises to the phase of 6 leaves. After this, the effectiveness of the drug decreases, although the weeds stop growing, they may not die.
The use of the drug "Caribou" allows you to control such weeds as thrown amaranth, euphorbia, nettles, chamomile, rezedu, Veronica, forget-me-not, sprouting of the blackthrow, celandine, ambrosia.
Application technology, solution consumption
It is recommended to carry out double processing of beet crops with the drug "Caribou" at air temperature from +15 to +25 ° ะก. At the time of the first use of the drug, the beets should be either in the state of germination (from 70% to 90% of the seedlings), or in the closing phase of the rows. The second treatment is carried out after 7-15 days after the first. 
Important! It is strongly not recommended to use the drug "Caribou" until the emergence of beet sprouts.Prepare a solution for spraying the field according to the instructions for use, based on the consumption rate in 30 g herbicide "Caribou" per hectare. The volume of the solution is 200 liters per hectare. First, water is poured into the container, then the required number of bags of "Caribou" is dissolved in it and the mixture is stirred until the drug is completely dissolved.
Other herbicides are usually added to the tank (already in liquid form). Then add the required amount of water, and at the end, it is mandatory to add the "TREND-90" surface-active substance (surfactant) at the rate of 200 ml per hectare. All these actions are performed with constant stirring of the solution.
The greatest effect of the herbicide effect is observed if Caribou is used in a mixture with other drugs. It is compatible with most pesticides, but before preparing such mixtures, it is advisable to consult with experts.
Important! Do not use "Caribou" in a mixture with organophosphate insecticides.
Safety measures at work
A drug refers to the third class of danger. When handling it, you must use rubber boots and gloves, overalls, goggles, respirator. It is desirable to carry out field processing in calm weather, but wind is allowed, the speed of which does not exceed 5 m / s.
Storage conditions
Store "Caribou" in the original packaging with intact integrity. In the room where it is stored, access for children should be excluded. In addition, it is stored separately from seeds and feed.
In general, the "Caribou" herbicide can be described as an effective means to combat dicotyledonous weeds that plague sugar beets. When properly applied, it allows you to completely get rid of many types of weeds.
