Herbicide Puma Super 100: instructions for use, mechanism of action and consumption rates

The purpose of highly selective herbicides is to protect emerging grasses from annual weeds. The use of herbicide Puma Super 100 is effective during the period of maximum coverage of the area with weeds, one treatment per season is enough. The drug does not have a depressing effect on weeds that appeared in the second wave, so it is important to clearly define the period of work.

Composition, purpose and release form of Puma Super 100

Herbicide Puma 100 belongs to the category of highly selective preparations intended for the treatment of cereal areas after germination, it is effective against many types of annual weeds.With the help of a herbicide, they fight wild oat, falaris, blackberry, foxtail, broomstick, bristles

The active substance is fenoxaprop-P-ethyl. The composition contains an antidote - mefenpir-diethyl. The drug is produced in the form of a concentrated emulsion, in which the active ingredient is 100 g/l, the antidote is 27 g/l.

The herbicide is sold in 5 liter cans. Manufacturer - German company Bayer.

How does the drug work?

The mechanism of the herbicide Puma is based on the complex effect of the active substance and the antidote:

1. Phenoxaprop-P-ethyl, once on the surface of the plant, penetrates into the internal tissues, moves with the juices in different directions. In the plant organism, as a result of a hydrolysis reaction, it turns into a free acidic compound, and acts as an inhibitor of the formation of fatty acids. The result is the cessation of the formation of cell membranes in plant tissues.
2. Mefenpir-diethyl - reduces the toxic effect of the active ingredient on cultivated vegetation. Moreover, the substance acts simultaneously as an antidote for cereals and a synergist for weeds, that is, it enhances the inhibitory effect on unwanted vegetation.

Protection period

Puma Super herbicide is effective against weedy cereal annuals growing on the sown area at the time of treatment. But it does not depress the weeds that appear in the second wave of the season. Therefore, for maximum processing efficiency, it is important to choose the optimal time when the sown area is covered mainly with annual weeds.

One spray is enough to keep the weeds at bay until the end of the growing season.

In case of abundant weed coverage, it is advisable to carry out individual spraying with herbicide during the period when weeds are most susceptible to chemical attack: before the completion of tillering.

Impact speed

Puma Super 100 begins to act a day after it hits the plants. Weeds are completely dead in a week or two.

Pros and cons of herbicide

Puma herbicide is popular with farmers as it has many benefits:

• application efficiency in different climatic conditions on any type of soil cover;
• selective action due to the presence of an antidote in the composition;
• rapid dying off of the green mass of weeds;
• protective period up to 6 weeks;
• Available for ground spraying and aerial spraying;
• no strict processing times;
• effective against many types of weeds;
• lack of resistance.

Farmers do not note any special disadvantages when using the drug. The only caveat is the lack of impact on the second wave of weeds.

How to prepare the working mixture?

To prepare the working fluid, take 5 ml of herbicide in a 10-liter bucket of water. Prepare the solution in stages:

1. Combine the emulsion with some water. Shake vigorously to make a homogeneous liquid.
2. The tank is 1/3 filled with water. The previously made emulsion liquid is carefully, with continuous stirring, poured into the tank water.
3. The resulting solution is thoroughly stirred. Add the remaining volume of water.

Before preparing the solution, check the serviceability of the sprayer, rinse the inner walls of the tank with water to remove the plaque remaining from other chemicals. Prepare the working fluid in an open area, away from food storage areas, people and pets.

How to properly spray the drug?

Optimal consumption of Puma Super is 0.6-0.8 liters per hectare. When working on a rainy day, the volume is increased to 1 liter per hectare. If the herbicide Puma Gold is used, then a concentration of 1-1.2 l / ha is taken. The consumption of working fluid for the treatment of crops and spring and winter wheat is 150-200 l/ha. Spraying is carried out once per growing season.

The instructions for use indicate that crops oppressed by adverse climatic conditions should not be sprayed. Work is not carried out in the middle of the day in sunny weather. The best time is right after sunrise or after sunset.

Mechanized measures can be carried out on the sown area 3 days after herbicide treatment.

Herbicide Safety

Puma Super 100 herbicide belongs to the 3rd class of toxic hazard for humans and animals - medium toxicity. For bees - class 4 - low-toxic substance. The chemical is not prohibited from spraying in the sanitary zone of reservoirs belonging to fish farms.

When preparing to work with the herbicide, you need to wear standard protective equipment:

• rubber work gloves;
• high closed shoes;
• clothes with long sleeves and trousers;
• rubberized apron;
• work glasses;
• respirator or at least a medical bandage.

Before starting work, you should warn neighbors not to let children and pets into the territory.

Phytotoxicity

Puma Super herbicide has no toxic effect on cultivated vegetation.

Barley is most susceptible to the drug: blanching or yellowing of the edges of the leaf blades is possible. But the negative effect is short-lived: after 2 weeks, the leaves of the cereal become green again. The phenomenon is observed infrequently, provoked by adverse climatic conditions, a decrease in air temperature on the day of processing.

Compatibility

Do not mix Puma Super with:

• herbicides based on 2,4-dichlorophenoxyacetic acid;
• Dicamba;
• herbicide Florasulam and its analogues;
• fluroxypyr acid-based chemicals;
• herbicides based on bromoxynil octanoate.

If a mixture is made with MCPA, then the concentration of this chemical should not exceed 400 g per hectare.

Before preparing the tank complex, it is necessary to check whether the chemicals to be combined are compatible. It is undesirable to mix concentrates directly without first diluting them with water.

Terms and rules of storage

Store Puma Super 100 in the canister in which it was purchased. For storage, choose a shaded place with more or less stable temperature indicators. Temperature limits - from -5 to +50 °C.

The shelf life of the herbicide is 2 years from the date of issue.

Existing analogues

Phenoxaprop-P-ethyl supplemented with an antidote contains the following herbicides:

• Irbis 100 from Chinese manufacturer Trust Chem Co;
• Jaguar Super 100 by AFD Chemicals;
• Eraser Extra from the Russian manufacturer "August".

All of the listed analogues act against a wide range of weeds, are characterized by high selective action, harmless to cultivated plants.
