Composition, purpose and form of release of "Caribou" weed remedy
The broad-spectrum herbicide belongs to the class of sulfomanilureas, characterized by high activity, selectivity, and long-term action.
The main substance of the drug "Karibu" triflusulfaron-methyl in the form of colorless crystals retains the stability of its properties in aqueous solutions.
The pesticide has a destructive effect on weeds at different stages of development. Already 10-15 days after weeds get on the leaves, they die. But the weeds that appeared after the treatment do not stop growing.
The manufacturer of the Karibu herbicide, the Moscow company FMS Corporation, produces the drug in packages of 150 grams. 4 packages are in a foil bag weighing 600 grams.
The preparative form is a powder with an active ingredient, fillers and surfactants. When diluted with water, a stable suspension of the agent is obtained.
The mechanism of action of the drug
The substance trifulsulfaron-methyl acts on the shoots of weeds for 10-14 days. Within 4-5 hours after spraying, signs of wilting appear in weeds. The absorption of the agent occurs through the leaves. And in wet weather, the pesticide enters the ground, penetrating into the plants through the roots.
Blocks the pesticide in weeds of carbohydrate metabolism. At the same time, the growth of herbs stops due to blockage of cell division.
The drug has no effect on the development of sugar beet. Temporary yellowing of the leaves of the crop may occur if the "Caribou" was used in hot (above 25 degrees Celsius) or cold (below 10 degrees) weather.
Impact speed and symptoms
The action of the drug is active when the weather is dry and the air temperature is in the range of 15-25 degrees Celsius.
The first signs of wilting are especially pronounced within 7-10 days. Finally, sugar beet fields are freed from weeds 15 days after spraying.
The effectiveness of the product will decrease if it starts to rain after the treatment.
Herbicide benefits
Farmers are advised to use the drug "Karibu" in the fields where sugar beets are grown, with which you can:
- control the appearance of dicotyledonous weeds;
- completely destroy weeds within 10-14 days;
- to clear the field of harmful plants before harvesting root crops;
- not to be afraid of the harmful effects of pesticides on human health, the surrounding nature, insects, birds.
Combine Caribou with other pesticides. The tool is convenient to store and transport.
Preparation of the working solution of the drug
It is necessary to prepare the tank mixture on the day of spraying the area with cultivated plants. In this case, the seedlings of sugar beet must reach such a height that the rows close.
Mix the herbicide powder with a small amount of water until it is completely dissolved. Then add water to the norm and turn on the stirrer again. It is necessary to pour in a product containing surfactants.
Using the ready-mix
Instructions for the use of "Caribou" consists of the following steps:
- On a hectare of sugar beet, take 30 grams of powder. Together with the "Trend 90" surfactant preparation (200 ml), 200 liters of the pesticide mixture are obtained.
- The first treatment should be scheduled when the weeds have grown to the cotyledon stage.
- The second time should be sprayed after 1-2 weeks when the second wave of weeds appears.
- They choose sunny calm weather for processing, with an air temperature in the range of 15-20 degrees Celsius.
Caribou quickly decomposes in the soil, which does not interfere with the use of the field for crops in the future.
Safety technology application
When working with tank mixtures of herbicide, safety rules must be observed. The use of personal protective equipment should not be ignored: rubber gloves, work clothes, respiratory mask, headgear.
After the spraying procedure, take a shower, disinfect clothes. If the solution gets on the skin and mucous membranes, it is advised to rinse them with water. And in case of poisoning, drink activated carbon tablets, induce vomiting.
Drug toxicity
Belongs "Karibu" to drugs with the 3rd class of toxicity. This means that the treatment against weeds is carried out:
- far from water bodies, human recreation sites, settlements, at least 2 kilometers;
- when the wind speed is about 3-4 meters per second;
- before 7 am or after 22 pm;
- with the notification of beekeepers whose apiaries are nearby.
You need to know that herbicides accumulate in the soil over time, so this must be taken into account when using a plot for cultivated crops.
Compatible with bipartite herbicides
The effectiveness of the drug "Karibu" increases if it is used in conjunction with herbicides against dicotyledonous weeds containing phenmedipham and desmedipham. With a tank mixture, weeds that are insensitive to the means are destroyed: bird and knotty mountaineer, white marsh, all types of Veronica, starworm.
Thistle and thistle are fought with the drug "Karibu", mixed with means based on clopyralid.
Compatibility is determined by the solubility of the drugs. When receiving a precipitate, it is not recommended to use the mixture.
How to store it correctly
Keep the wettable powder in a tightly closed container. It cannot be stored in rooms where livestock and poultry feed, food products are located.
Do not leave powder bags in sunny places, in the rain. The entire working solution is used without leaving it in the tanks.
Are there any analogues
Farmers are using Miura herbicide against weeds in sugar beet fields. He fights not only with cereals, but also dicotyledonous weeds, together with the preparations "Pilot", "Biceps", "Hacker".
