Santal - systemic herbicide against weeds in sunflower crops, Kyiv region region.

Santal - Two-component post-emergence systemic herbicide against grass and dicotyledonous weeds onsunflower crops, resistant to imidazolinones.

Active substance: Imazamox, 33 g/l + imazapyr, 15 g/l
Preparative form: Soluble concentrate
Culture: Sunflower.
The container is 10 liters, the price is for 1 liter.

Advantages:
Improved formulation of the drug, high quality coating and retention of active substances.
Enhanced protection against a complex of weeds and sunflower beetle.
Highly active action both through the soil and through the leaves.
Reliable control of subsequent waves of weeds (ground action).

Mechanism of action;
Imazamox and imazapyr are adsorbed through the roots and leaf surface of plants, move through the xylem and phloem, and accumulate at the growing points. In weeds, the active substances inhibit the synthesis of the enzyme acetohydroxy acid (ALS), which is responsible for the formation of aliphatic amino acids (valine, leucine and isoleucine). Protein synthesis is disturbed, which leads to disruption of DNA synthesis and slowing down of plant cell growth, which leads to the death of weeds.

Range of action:(//tractor-service.com)
Weeds sensitive to the drug: ragweed (up to 4 leaves), field birch, birch mustard,mustard, sweet cornflower, chicken millet, польова, нетреба звичайна, рутка лікарська, зірочник середній, канатник Теофраста, лобода біла, осот (види), грицики звичайні, паслін чорний, жабрій звичайний, підмаренник чіпкий, просо куряче, wild radish, chamomile (species), mouse (species), shrike (species), field plantain, sunflower wolfberry.

General recommendations:
The optimal period of treatment with Santal is the period when weeds are in the early stages of development (up to 2-4 leaves), and cereal weeds - 1-3 leaves. It is not recommended to use the drug before the phase of 2 true leaves of the culture. In some cases, yellowing of leaves or tops of plants may appear after the application of herbicide on sunflower leaves. The manifestation of these symptoms does not mean a negative effect of the herbicide on sunflower plants and its yield. As a rule, such symptoms appear after processing as a result of the effect on the plant of stressful weather conditions (drought, heat, low temperatures, etc.). About 10-14 days after treatment, these symptoms on the plants disappear. Rain 1 hour after application does not affect the effectiveness of the drug. When used on areas with minimal tillage or on areas with a large amount of crop residues, the soil effect of the drug may be reduced. Within 10 days after application, it is necessary to exclude mechanical treatments that will break the herbicide "screen" on the field. When used in tank mixtures with other herbicides, the effect of the drug is enhanced, which can lead to suppression of sunflower plants, therefore, the use together with other herbicides is not recommended.

Rate of consumption of working fluid
200–400 l/ha.

Regulation of application;

Culture Object Drug consumption rate, l/ha Treatment period Maximum number of treatments

Sunflower (hybrids resistant to imidazolinones)
Cereal and dicotyledonous weeds 1.0-1.2*
Spraying crops in the 4-leaf phase of the culture and in the initial phases of weed development
1
* 1.0 l/ha is used in the early stages of the development of weeds, when they are in the stage of active growth and on the area where there is no sunflower wolfberry;
1.2 l/ha is the main recommended rate when weeds are at later stages of development, as well as in the presence of problematic weeds. activities
