Herbicide Luger: instructions for use, mechanism of action and consumption rates

Highly effective two-component preparation is used to destroy weeds in areas occupied by cereals and corn. With the help of Luger herbicide quickly get rid of dicotyledonous annuals and perennials that are immune to dichlorophenoxyacetic acid and 2M-4X. The drug is highly toxic, so safety rules must be observed when using.

Composition, release form and purpose

Luger herbicide is effective against a wide range of dicotyledonous weeds and is used in areas occupied by cereal crops and corn.

Active ingredients:

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 goods are packed into boxes on 4 canisters in everyone. Manufacturer - Hungarian agrochemical company Peters and Burg.

Mechanism of action of Luger

Florasulam inhibits amino acid synthesis by inhibiting the enzyme acetolactate synthase. Dichlorophenoxyacetic acid acts as an inhibitor of growth processes.

The Luger drug acts systemically: an hour after it hits the surface of the plant, it penetrates the tissues, blocks cell division both in the aerial and root parts.

Impact speed

Growth processes in plant tissues stop after a day. Visual symptoms of weed dying are observed after 3-4 days. The complete release of the site from weeds occurs after 2 weeks.

Protection period

The herbicide acts on plants that have already germinated at the time of treatment. Crops remain weed free until the end of the growing season.

Main positives and negatives

The popularity of Luger herbicide is due to many advantages. Chemical:

handles a wide range of dicotyledonous annuals and perennials resistant to other herbicide formulations;
effectively destroys complex weed species - cornflower, sow thistle, bedstraw;
has a depressing effect even on overgrown weeds;
gives quick positive results;
maintains efficiency at low air temperatures and during dry periods;
does not wash off with 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.

Agrarians do not notice any special shortcomings. It should be noted only the high toxicity of the drug, the need to use protective equipment.

Consumption of working fluid

The table shows the rates and terms of application of Luger for different types of cultivated plants.

Weed speciesDrug rate, l/haTerm of application spring and winter cereals corn 3-4 leaf stage of cultivated plant, beginning of weed development

Cultural species
dicotyledonous annuals and some perennials	0.4	stage tillering of the crop, the beginning of the development of weeds (spring processing of winter cereals) internodes on a cultivated plant, initial development of weeds (if bedstraw prevails and the weather did not allow processing earlier)
dicotyledonous annuals and some perennials	0.4	Dicotyledonous annuals and some perennials	0.6
	0.5	Cultural species stage 5-6 leaves (with bedstraw predominating if the weather prevented processing earlier)
	0.5

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 the volume. With the stirrer running, pour in a measured amount of the mother liquor of the emulsion. To prepare the mother liquor, a separate tank is filled with water by a quarter, the concentrate is poured in, water is added until the volume is filled with continuous stirring. After the mother liquor is combined with water in the tank of the spraying device, with the mixer running, the remaining volume of water is added. Such a scheme for preparing the solution does not allow precipitation of the active substances of the herbicide.

The working fluid is prepared at an equipped filling site with a protective coating, more than 200 m away from residential and livestock buildings, water sources, food warehouses, and crop areas. The made solution is used immediately.

After carrying out the work, the tanks where the mother and working solutions were located 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

Luger is in the 2nd hazard class for humans (highly toxic substance), in the 3rd for bees (moderate toxicity).

Working with the herbicide is possible only when using personal protective equipment for the skin, visual and respiratory organs. The employee must wear a respirator, work goggles, rubber gloves, high shoes, tight closed clothing. In case of chemical poisoning, you should immediately call an ambulance.

Highly toxic herbicide is prohibited:

on the plot;
for aerial spraying;
in the sanitary zone of a reservoir belonging to a fish farm.

Mechanized work is allowed 3 days after the treatment of the site.

Phytotoxicity

Herbicide Luger does not have a toxic effect on sprayed crop plants if the instructions for use are followed. Cereal species are not susceptible to the drug, only dicotyledonous herbs are sensitive.

Possibility of resistance

Due to its dual-action formula, resistance is low.

Compatibility

Luger is combined in tanks with herbicide chemicals based on sulfonylurea, isoproturon, dicamba, carfentrazone-ethyl, insecticides and fungicides.Do not use Luger together with chemicals including fenoxaprop-p-ethyl and clodinafop-propargyl, as the effect of the latter is weakened.

Before mixing herbicide with any agrochemicals, the ingredients should be tested for compatibility.

Terms and conditions of storage of the drug

Store Luger in a warehouse equipped for chemicals, in the 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.
