How to use herbicides correctly

One of the basic rules when applying herbicides is not to use them in dry and hot weather. The best temperature for applying herbicides to the soil is from 18 to 23 degrees.

The greatest efficiency of soil herbicides is manifested in conditions when the soil on the surface is moistened to the limit of the lowest moisture capacity - the moisture content of breaking capillary bonds. On clay and sandy soils, use the minimum recommended dosage.

When using conventional field sprayers, the fluid consumption will be 250-400 liters per hectare. It must be borne in mind that in no case should herbicides be used in dry weather, in this case the fluid consumption doubles.

The best time to use herbicides is in the morning or evening.


The product of the German company BASF destroys cereal and dicotyledonous weeds in sunflowers, soybeans and peas. It is produced in the form of a solution in plastic containers with a volume of 10 liters.

The active ingredient is imazamox in an amount of 40 grams per liter. The active ingredient stops the growth of weeds just a few hours after spraying, since it reduces the level of required amino acids.

Pulsar has a third hazard class for mammals and bees, that is, for them it is minimally dangerous.


Advantages and disadvantages of herbicide Pulsar


·         at suitable humidity prevents the development of a new generation of weeds;

·         harmless to crops that will be sown on the treated area after harvesting sunflowers, peas and soybeans;

·        systemic action is suitable for soil activity;

·        effectively removes cereal annual and dicotyledonous weeds;

·         it has a wide range of applications and mild aftereffect;

·         acts quickly.

The disadvantages include only the high cost of Pulsar. It is classified as a new generation herbicide, so it has minimal effect on the soil. But in order to achieve a positive result, you must strictly follow the instructions for use.

 Decreasing / increasing the dose may negatively affect the quality and quantity of the crop.


Mechanism of action

Pulsar, falling on a weed, is completely absorbed by it. In just a few hours, the plant stops producing amino acids, blocking protein synthesis, which ensures its growth.

The effect of the herbicide is noticeable 21-30 days after spraying. The speed of action is influenced by the number and size of weeds, as well as climatic features.

Consumption rates

To achieve the maximum positive result, you need to follow the consumption rates.

Dicotyledons, annuals and perennials

When the seedlings have reached the 2-3 leaf phase


Instructions for the use of herbicide Pulsar

It is best to process plants when 2-3 trifoliate leaves have already appeared on them . After the 14-28 days procedure, you should refrain from inter-row cultivation, as it can disturb the herbicide screen. 

It is enough to treat the sunflower with herbicide once a season . You can repeat the procedure in case of severe drought.

Best processing time

It is better to spray on a windless day, otherwise the working solution will scatter to other areas. If the wind speed exceeds 5 meters, the procedure is prohibited.

Precautions during operation

The indisputable advantage of the herbicide is safety for humans, bees and animals. Despite this, it is not recommended to use it near water bodies and apiaries.

During processing, it is necessary to control so that the Pulsar does not get on other crops, since it can negatively affect them.



  Pulsar not only performs the main task well, but also contributes to an increase in yield, since the soil provides cultivated plants with the proper amount of nutrients.
