If the following points are not observed, it may damage trees or other cultivated plants. Do not apply to fruit trees or other crops where it is not recommended, where the roots can be found or where the medicine can be reached by moving or washing. Avoid contamination of the plants with the crops where the drug is not recommended during application. Do not contaminate the streams and irrigation waters.

GENERAL INFORMATION: STENO is a herbicide used in the fight against single and perennial narrow and broad leaf weeds in corn.

* It is not used in gin and sweet corn.

* STENO must be used with the SPRING ADHESIVE supplied. The dose of the spreading adhesive is 25 ml per decare.

HOW TO USE: For best results, STENO should be used in the early growing periods of weeds (2-4 leaves or 5-10 cm diameter or height). Especially for combating Sirken (Chenopodium album) and Pork Velcro (Xanthium strumarium), application is recommended in 2-4 leaf period. For the control of perennial weeds growing from the rhizome such as Kanyaş (Sorghum halepense), the application should be done during the weeding period of the weed. During application, maize should be in the period of 1-8 true leaves, phytotoxicity may be observed in later applications of maize. For the best result, there should be no precipitation for 4 hours after spraying.



- STENO should not be applied in fields where systemic organic phosphorous insecticides are used during corn cultivation or inter-row cultivation.

- STENO should not be used within 7 days if corn is applied with leaves with an organic phosphorous insecticide.

- These organic phosphorous insecticides should not be applied within 4 days after using STENO in corn.

- High air temperature may cause temporary phytotoxicity in some sensitive corn varieties. For this reason, it is recommended to apply in the evening.


As with other Sulfonylurea, STENO's effect is acetolactate enzyme synthesis. This enzyme is needed in the production of essential protein blocks valine and isoleucine. As a result of inhibition, growth stops immediately and the plant eventually dies. The absence of this enzyme in humans and animals helps explain the low toxicity of STENO. In susceptible plant species, the first signs of STENO activity appear in the meristematic tissue. Growth stops immediately after STENO administration in these plants. Other symptoms such as chlorosis, necrosis and deformities in the leaves appear a few days later. Herbs die within 10 to 20 days.


STENO's permanence in the soil is short. When used in accordance with the recommendations, any kind of cultivated crops that enter the normal cultivation crop can be planted after corn.


It is not phytotoxic in corn plants when used according to the recommendations.

STABILITY: STENO should not be mixed with organic phosphorous insecticides, since phytotoxicity may be seen in the corn plant. Before mixing any tanks with other drugs, physical, chemical and biological miscibility needs to be observed with small applications.
