A highly effective two-component preparation is used to destroy weeds in areas occupied by cereals and corn. Using the Luger herbicide, you can quickly get rid of dicotyledonous annuals and perennials that are resistant to dichlorophenoxyacetic acid and 2M-4X. The drug is highly toxic, so when using it you must follow safety rules.

Composition, release form and purpose
Luger herbicide is effective against a large list of dicotyledonous weed species and is used in areas occupied by cereal crops and corn.
Active components:
- 2,4-dichlorophenoxyacetic acid – 300 g/l;
- florasulam – 6 g/l.
The herbicide is sold as a suspension emulsion in plastic 5-liter canisters. The product is packed in boxes of 4 canisters each. Manufacturer: Hungarian agrochemical company Peters and Burg.
Mechanism of action of the drug Luger
Florasulam inhibits amino acid synthesis by inhibiting the enzyme acetolactate synthase. Dichlorophenoxyacetic acid acts as a growth inhibitor.
The drug Luger acts systemically: an hour after it hits the surface of the plant, it penetrates into the tissue, blocks cell division in both the above-ground and root parts.
Impact speed
Growth processes in plant tissues stop after a day. Visual symptoms of dying weeds are observed after 3-4 days. Complete clearing of the area from weeds occurs after 2 weeks.
Period of protective action
The herbicide affects plants that have already sprouted at the time of treatment. Crops remain free from weeds until the end of the growing season.
Main positive and negative aspects
The popularity of Luger herbicide is due to many advantages. Chemical:
- copes with a large list of dicotyledonous annuals and perennials that are resistant to other herbicide compounds;
- effectively destroys complex weed species - cornflower, sow thistle, bedstraw;
- has a suppressive effect even on overgrown weeds;
- gives a quick positive result;
- remains effective at low air temperatures and during dry periods;
- is not washed off by precipitation an hour after contact with the plant;
- can be used at different stages of weed formation - from tillering to the appearance of the second internode;
- has European quality.
Farmers do not notice any particular shortcomings. It should be noted only the high toxicity of the drug and the need to use protective equipment.
Working fluid flow
The table shows the norms and terms of use of the drug Luger for different types of cultivated plants.
| Cultural view | Weedy look | Drug rate, l/ha | Application period |
| spring and winter cereals | dicotyledonous annuals and some perennials | 0,4 | stage of tillering of the crop, beginning of weed development (spring treatment of winter cereals) |
| 0,6 | stage of appearance of 2 internodes on a cultivated plant, initial development of weeds (if bedstraw predominates, and the weather did not allow treatment earlier) | ||
| corn | dicotyledonous annuals and some perennials | 0,6 | stage of 3-4 leaves of a cultivated plant, the beginning of weed development |
| 0,5 | stage of 5-6 leaves of a cultivated species (with a predominance of bedstraw, if the weather did not allow treatment earlier) |
Waiting period - 60 days, frequency of use - 1. Consumption of working solution - 200-300 liters per hectare.
Instructions for the preparation and use of the working solution
The tank of the spraying device is filled with water to a third of its volume. With the mixer running, pour in a measured amount of the emulsion mother liquor. To prepare the mother solution, fill a separate tank a quarter full of water, pour in the concentrate, add water until the volume is full with continuous stirring.After combining the mother liquor with water in the tank of the spraying device, with the mixer running, add the remaining volume of water. This solution preparation scheme does not allow the active substances of the herbicide to precipitate.
The working fluid is prepared at an equipped filling site with a protective coating, located at a distance of more than 200 m from residential and livestock buildings, water sources, food warehouses, and cultivated areas. The prepared solution is used immediately.
After work, the tanks containing the mother and working solutions are thoroughly washed using cleaning products.
Luger herbicide is sprayed on crops in the spring at an air temperature of +5 °C.
Precautions for use
The drug Luger is included in the 2nd hazard class for humans (highly toxic substance), in the 3rd for bees (moderate toxicity).
Working with the herbicide is possible only with the use of personal protective equipment for the skin, visual and respiratory organs. The worker must wear a respirator, work glasses, rubber gloves, high shoes, and tight closed clothing. If you are poisoned by a chemical, you should immediately call emergency medical help.
It is prohibited to use a highly toxic herbicide:
- on a personal plot;
- for spraying by aircraft;
- in the sanitary zone of a reservoir belonging to a fish farm.
Mechanized work is permitted 3 days after processing the site.
Phytotoxicity
Luger herbicide does not have a toxic effect on sprayed crops if the instructions for use are followed. Cereal species are not susceptible to the drug; only dicotyledonous herbs are sensitive.
Possibility of resistance
Thanks to the two-component composition, which provides double action, the likelihood of resistance is low.
Compatibility
Luger is combined in tanks with herbicidal chemicals based on sulfonylurea, isoproturon, dicamba, carfentrazone-ethyl, insecticides and fungicides. Luger should not be used together with chemicals including fenoxaprop-P-ethyl and clodinafop-propargyl, since the effect of the latter is weakened.
Before mixing the herbicide with any agrochemicals, the ingredients should be checked for compatibility.
Terms and conditions of storage of the drug
Luger is stored in a warehouse equipped for chemicals, in a hermetically sealed canister in which it was sold. Storage temperature – from -10 to +35 °C. It is unacceptable to leave the chemical near food and feed products.
The shelf life of the herbicide is 3 years.
Similar means
There are many analogues of the Luger herbicide in terms of active substances:
- Florastar;
- Disulam;
- Oprichnik;
- Premiere;
- Camaro;
- Elant Extra.
The listed preparations are a two-component suspension emulsion and are used to destroy a large list of dicotyledonous weeds in areas occupied by cereal species and corn.
Like Luger, they are characterized by rapid action, destroy even chemically resistant and overgrown plants, and do not have a negative effect on cultivated cereal vegetation.
