Tara
0.5 kg
Culture
Advantages
A wide range of controlled weeds, especially such as thistles, bitter gorse, etc.(//tractor-service.com)
Extended terms of use: from 2 leaves to the appearance of a flag leaf.
The onset of action on weeds is already 2-3 hours after application.
Has no restrictions on crop rotation.
Mechanism of action
Tribenuron-methyl stops the cell division of sensitive weeds, resulting in their growth stopping within a few hours of treatment. Visible symptoms appear after 5-8 days, and weed death occurs after 10-25 days. Less sensitive weeds and those at a later stage of growth may not be killed, but their growth stops and they no longer compete with the crop for nutrients and water. Warm weather increases the rate of action of the herbicide, while cool and dry weather slows it down.
Properties
Alfa-Star provides effective control of most annual and perennial dicotyledonous weeds, including those resistant to drugs of the 2,4-D group. For maximum effectiveness, the herbicide should be applied during the period of active growth of weeds in the phase of 2-4 leaves of annuals and rosettes (10-15 cm) of perennials. The systemic action of the drug makes it possible to penetrate through the leaves to the roots, destroying the entire plant. The best period of control of the pink thistle is in the rosette phase, and the tenacious nightshade is up to the 4th whorl. Due to the rapid disintegration of the drug in the soil, there are no restrictions for the following crops in crop rotation.
General recommendations
The drug cannot be used if the plants are wet from dew or rain, and if rain is expected within three hours after treatment. In the case of a thick stand of culture or very strong clogging, the maximum volume of the working liquid should be used. To expand the spectrum of controlled dicotyledonous weeds, it is possible to use tank mixtures: Alfa-Star (10-15 g/ha) + Alfa-Dicamba (0.15-0.2 l/ha) + surfactant Alfalip Extra (0.2-0.25 l/ha); Alfa-Star (15-20 g/ha) + Hammer (15-20 g/ha) + surfactant Alfalip Extra (0.2-0.25 l/ha). When using with other drugs or surface-active substances, Alfa-Star is first poured into the tanksprayer, and then all other products are added. The working solution must be used within 24 hours. Apply in dry weather. Rain within 3 hours after spraying can reduce the effectiveness of the drug. Avoid spilling the working solution on neighboring crops that are sensitive to the herbicide.
