WEBB herbicide - analogue Granstar gold

Postemergence herbicide of systemic action for control of annual and some perennial dicotyledonous weeds in cereal crops

Active substance: tribenuron-methyl 750 g/kg

Formulation: water soluble granules

The benefits of using herbicide Webb

- Herbicide used to inhibit and destroy a wide spectrum of dicotyledonous weeds, including resistant to drugs on the basis of 2,4 D;

- It is not phytotoxic to the cultural cereal plants. Even when using the drug until the phase flag leaf, fetotoksicnosti not shown;

- Long period of application ― from the emergence of the 2 leaf to flag leaf culture;

The herbicide is characterized by high speed action (5-8 days) and a long protective period (30 days);

- Does not restrict the alternation of crops in crop rotation;

- Significantly reduces the herbicidal effect on the soil.

The mechanism of action of the herbicide Webb

The drug, which is composed of tribenuron methyl, sulfate Amon and other auxiliary substances enters the plant through leaves and roots. The Webb effect is manifested by inhibition of activity of enzyme, which leads to blocking of the synthesis of essential amino acids valine and isoleucine with subsequent suspension and violation of differentiation of cells in the growing points of the plant. Visual herbicide effect is manifested in the form of suspension of plant growth and its subsequent death in 1-2 weeks.

The spectrum of action of the drug Webb

The herbicide used to destroy a broad spectrum of dicotyledonous weeds.

The herbicide is safe for bees, birds, fish.

The use of the herbicide Webb

Winter wheat:

The drug consumption rate: 15-25 g/ha

Harmful objects: annual and some perennial dicotyledonous of Solanki

Maximum number of treatments: 1

Barley:

The drug consumption rate: 15-20 g/ha

Harmful objects: annual and some perennial dicotyledonous of Solanki

Method and time of processing: spraying in the period from the phase of 2-3 leaves before the plants in the tube.

Maximum number of treatments: 1

Technology features making

The maximum effect is achieved when the herbicide treatment of crops during active growth of young weeds (2-4 leaves ― annual, rosette perennial).

The rate of application of herbicide for winter wheat is set depending on the phase of development of weeds. The maximum rate of flow is established in the presence of outgrown (more 4-h leaves a one-year, steblevka ― perennial) and the dominance of the crops moderately sensitive and resistant weeds.

Visual signs of drug action depend on species composition of weeds, their stages of development and climatic conditions in the treatment period. The first signs of chlorosis, necrosis appear a few days after treatment, after 1-2 weeks the weeds will die. Some moderately sensitive weeds remain green for a long time, but their development is significantly suppressed.

When processing moderately sensitive weeds in the later stages of development and in dry weather, signs of herbicide action appear later.

Warm and humid weather enhances the activity of action of the drug, long-term dry period reduces its activity.

The rain that falls for three hours after application of the herbicide may wash him from the surface of the leaves before the full penetration which also reduces the activity of his actions.

On wheat and barley conducted to the spraying of the cleavers ― to the phase of the fourth whorl, but against sow Thistle field with a height of 10-15 cm

To enhance the action of the drug may use it in tank mixtures with other herbicides that are used on cereals and cereal crops, as well as liquid fertilizers.

The consumption rate of working liquid of 200-300 l/ha

Application time after spraying for mechanized work ― 3days
