Sunflower (hybrids resistant to imidazolines) Cereal and dicotyledonous weeds 1.0-1.2 * Spraying of 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 when problematic weeds are present.
Advantages(//tractor-service.com)
• Improved formulation of the drug.
• Improved coverage and retention of active substances.
• Highly active action both through the soil and through the leaves.
• Enhanced protection against a complex of weeds and sunflower beetle.
• 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.
Properties
Penetrating through the leaves and stems of sensitive weeds, clethodim and hyzalofop-p-ethyl are concentrated at the growth points of shoots and rhizomes. Weed growth stops within a day after application. Due to the presence of cletodym in the composition of Cayman, the visual symptoms of the herbicidal effect appear very quickly - after 3-5 days in the form of browning and dying of growth points and the acquisition of chlorotic color by the leaves. Complete death of the aerial part occurs after 7-12 days. During 14-21 days, rhizomes dry out. Cayman herbicide, thanks to a unique combination of active substances from different chemical groups, provides control of a complex of cereal weeds and has improved selectivity for cultivated plants, primarily, such as sunflower and soybean.
Spectrum of action
Weeds sensitive to the drug: ragweed (species), field birch, birch mustard, field mustard, common netreba, medicinal root, medium star, Teofast's rope, white quinoa, thistle (species), common sorrel, black solanum, common gill, Common marigold, chicken millet, wild radish, chamomile (species), mouse (species), sedge (species), field stiltgrass, sunflower wolfberry
General recommendations
The optimal period of treatment with Santal is the period when the weeds are in the early stages of development (up to 4 leaves), which, as a rule, corresponds to the stage of development of 4 true leaves in sunflower. It is not recommended to use the drug before the phase of 2 true leaves in 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 where there is a large amount of crop residues, the soil action 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 the suppression of sunflower plants, so the use together with other herbicides is not recommended.
Rate of consumption of working fluid
200–400 l/ha.
Place in crop rotation
After using the herbicide in crop rotation, the following crops can be sown through:
The term Culture
4 months (autumn) winter wheat, winter rye
9 months (spring) spring wheat, soybeans, peas, beans, alfalfa,corn*, sorghum*, spring barley*, oats*
18 months winter and spring wheat, winter and spring barley, rye, oats, corn, sunflower,potato, soybeans, peas, beans, alfalfa, millet, vegetables
24 months sugar beet, rapeseed, winter and spring wheat, winter and spring barley, rye, oats, corn, sunflower, potatoes, soybeans, peas, beans, alfalfa, millet, vegetables
* Phytotoxicity is absent at soil pH greater than 6.2 and sufficient rainfall during the season (> 200 mm). A sufficient amount of moisture from the moment of application of the drug to the sowing of the next crop in the crop rotation enhances the microbiological decomposition of the active substances. On heavy soils and soils with a low pH, the decay of active substances proceeds more slowly than on light soils. It is not recommended to use drugs from the group of imidazolines (imazetapyr, imazamox, imazapyr) within 3 years after using the herbicide.
