Active ingredients and formulation

The protection period is 60 days.

Pros and cons of Pledge

Herbicide Benefits:

• can be used before and after the emergence of the main crop;
• compatible with various plant protection products;
• burns weeds;

Weed control measures

Pledge herbicide is prepared in the following proportions (at a working fluid flow rate of 200-300 l/ha):

1. For sunflower: 0.08-0.1 kg/ha.
2. For soybeans: 0.1-0.12 kg/ha.

How to prepare and use working mix

Pledge weed control herbicide can be applied before and after sunflower or soybean seedlings, according to the instructions. For pre-emergence use of the herbicide, the soil must be properly prepared and have an adequate supply of moisture. The drug can remain on the soil surface for a long time, and loosening will violate the protective action of the herbicidal agent.

Herbicide is used immediately after sowing the main crops, while they have not yet sprouted. Irrigation can be carried out 2-3 days after sowing.

The drug can be used after the appearance of 2-4 true leaves of the main culture. True, during the cotyledon period, this remedy is prohibited. Weeds are best sprayed at the very beginning of development. Pledge burns weeds and provides a good start for major crops. It is not recommended to use the herbicide if the sunflower or soybeans have been severely affected by frost, drought, poor nutrition, diseases, insects.

Spraying with herbicide using tractor sprayers is carried out in the morning (until 10 am) and evening (from 18 to 22) hours. Before preparing the solution, the tank is thoroughly washed. The herbicide mixture itself is prepared on the day of spraying. The tank is half filled with clean, uncontaminated water. With the mixer on, the herbicide powder is added. Then add the rest of the liquid. After spraying, all equipment must be thoroughly washed.

Use safety

Pregnant women, teenagers under 18 years of age, people on medical grounds are not allowed to work on irrigating the field with a herbicidal agent. Work with the herbicide should be in a protective suit, mask or respirator, boots, gloves. After field work, you need to wash your hands and face with warm water and soap, rinse your mouth with a soda solution. It is forbidden to inhale vapors and drink the herbicide mixture.

Toxicity

The drug has phytotoxicity to a number of crops. At the place where the field was processed from weeds, planting of corn and wheat is allowed no earlier than 30 days later. Barley, beans can be sown after 4 months. Oats, rapeseed, vegetables, beets are allowed to be sown only after 1 year.

The drug belongs to the 2nd class of danger for humans and the 3rd class - for beneficial insects. The use of herbicide is undesirable during the active summer of bees. It is forbidden to carry out processing from the air in the buffer zone, near the reservoirs for breeding fish.

Compatible with other substances?

Pledge can be used with Skaba surfactant. It is undesirable to use this herbicide with other adjuvants. The combined use of Pledge and other pesticides (Pendimetalin, Trifluralin), mineral fertilizers and growth stimulants is not allowed in tank mixtures.Other graminicides can be used no earlier than 3 days later. With severe clogging, Pledge can be used in tank mixes with acetochlor, flurochloridone, propisochlor, dimethenamid-P.

Rules and terms of storage

The pesticide is stored in accordance with accepted regulations, that is, in a separate room for storing plant protection chemicals.
