Active Fraction Content Tribenuron methyl, 750 g/L

Chemical Group Sulphonylureas

Preparative Form Water-soluble granules

WHO Classification III class (Moderate hazard substance), Non-hazardous for bees, birds, and fishes

Advantages of product

The preparation provides a wide range of controlled weeds, especially such as sow-thistle (Sonchus oleraceus), catchweed bedstraw (Galium aparine).

The low standard of entering – 15 – 25 g/ha, enabling to use easy and simple.

Prolonged terms for use: from 2 leaves till a flag leaf appears in culture.

The long-lasting protection period – 30 days.

The preparation is compatible with the most means designed for the protection of plants.

There is no phytotoxicity for spiked cereals.

It is not restricted in crop rotation.

It is effective starting from +5°C of air temperature.

Recommendations for Use

Application Features

The best effect is achieved when the preparation is entered in the period when weeds are actively growing (a phase when 2 – 4 leaves appear in annual weeds, a rosette – in perennial ones). The culture development phase can be from 2 – 3 leaves to the appearance of a flag leaf. The optimum air temperature varies from + 15°C up to + 25°C. However, it can also be used at the temperatures of + 5° -7°С, but the weeds to be treated should be vegetating (i.e. in the stage of active growth). Treatment at low temperatures does not affect the effectiveness of the preparation, but only slightly increases the duration of the onset of the death of weeds. In the presence of overgrown and prevalence in crops of middle-sensitive and persistent weeds, the maximum standard of the preparation consumption should apply.

Spray Material Consumption Standards

200-300
L/ha

Compatibility

The preparation is compatible with most plant protection products to be used in order to protect cereal crops, and with liquid fertilizers. However, in each particular case, before the tank mix is prepared, it should be tested whether it is compatible or not.

Precautions in Use

Do not allow the spray solution to be transferred to neighbouring cultures that are sensitive to herbicide. The rain for 3 hours after spraying can wash off the herbicide before it is fully penetrated and reduce its effectiveness.

Mechanism of Action

The active substance of the preparation – tribenuron methyl - by the method of action on the plant belongs to inhibitors of the synthesis of amino acids. Penetrating the plant through leaves, stems and roots, it is transported to growth points, blocks the production of basic amino acids and the division of plant cells. 2-3 hours after the sensitive plants of weeds have been treated with such the herbicide as SHERIFF, they are suspending in growth and development, stop absorbing water and minerals from the soil, and compete with cultivated plants. Visual signs of the preparation effect will appear 5-8 days later and manifest themselves in the rooting and death of plants. Young weeds are killed 2-3 days before the weeds of later stages of development.
