Selective herbicide with high biological efficiency, for post-emergence protection of corn crops from a complex of annual and perennial cereal and dicotyledonous weeds.
Active substance:
nicosulfuron, 30 g/l mesotrione, 75 g/l
Formulation:
oil dispersion
Packing:
1 L, 5 L, 10 L, 20 L
Mode of action:
Nicosulfuron – absorbed by the leaves and stalks of weeds, inhibits cell division by blocking the enzyme ALS (acetolactate synthetase), which is involved in the synthesis of basic amino acids. Weeds quickly stop growing and competing with the crop, take a reddish shade after a week and gradually die completely (after about three weeks).
Mesotrione inhibits the enzyme HPPD (pi-hydroxyphenyl-pyruvate dehydrogenase), which is involved in the conversion of tyrosic acid to plastoquinones.
The last are an important elements in the synthesis of carotenoids. These compounds, expand the absorption spectrum of chlorophyll to infrared, thus mesotrione is an inhibitor of photosynthesis. Weeds quickly stop photosynthesis, lose their green color and die. Mesotrione also has a prolonged soil effect. (It is capable of controlling the emergence of several subsequent waves of annual dicotyled weeds in the soil).

Spraying of crops during the growing season in phases from 2 to 8 leaves of culture, inclusive |
Compatible with other pesticides, but before mixing it is recommended to definitely test for their physico-chemical compatibility.
• the next year after the use of the product is not recommended to grow sugar beets, peas and vegetables. Soy, sunflower and rape are recommended to be sown after plowing. Corn, sorghum, wheat, barley – without restrictions;
• the optimal time for application is the phase of 3-5 leaves of corn, when annual weeds are in the phase of 2-4 true leaves.
Speed of action of the product:
70-80 percent of the product penetrates the plant within 24 hours and causes the stop of weed growth 1-2 days. The first symptoms of action are discoloration of growth points, gradually chlorosis spreads to the whole plant and tissue necrosis occurs. Complete death occurs within 1-3 weeks, depending on the type of weeds and their physiological condition at the time of treatment. The minimum protection period is 20 days. Under the certain conditions (cold and humid weather, daytime t ° below 20 ° C, rapid change of temperature), short-term chlorosis may occur after herbicide application, mainly in the middle part of the leaf. Under such conditions, corn plants have a weakening of metabolism and selective active substances are unevenly distributed throughout the plant. However, these symptoms quickly disappear without having a negative impact on the growth and yield of the crop. Under optimal conditions, the product disintegrats rapidly and is excreted by corn plants.
!Do not use the product after treatment of seeds or corn areas with organophosphorus insecticides. Do not use on hybridization sites.
• full control of a wide range of annual and perennial cereal and dicotyledonous weeds;

• wide window of application: 2-8 leaves of culture;
• due to the soil action prevents the appearance of the following waves of dicotyledonous weeds;
• able to control sunflower (common, IMI and sulfure resistant);
• lack of phytotoxicity on culture;
• improved formulation – does not require the addition of surfactants.
