Viper On, 5 litres

Viper ON is a Corteva herbicide designed for rice protection. It is a post-emergence professional herbicide based on penoxsulam 16 g/l + triclopyr butotyl 120 g/l that acts differently than other products.

Benefits:
- very effective against weeds which are resistant to other modes of action such as ALS inhibitor herbicides
- slows down and inhibits weeds growth
- protects your rice crops and is economical on the long term
- versatile application, easy and safe to apply
- it can be applied in dry rice, wet or saturated soil or "at the water's edge" and in dry seeding rice

Action mode:
- Penoxsulam inhibits the enzyme acetolactate synthase (ALS) and prevents the biosynthesis of amino acids, while triclopyr inhibits plant growth.
- The product is absorbed mainly by the leaves and only partially by the roots and is translocated in the meristem tissues of the plants.
- Weed growth is slowed after a few hours, even if the first control symptoms appear 5-10 days after application and the final result is reached after 3-4 weeks.

Methods of application:
- Start applying from 2 leaves stage to the end of twinning of the rice crop. The timing of herbicide application is determined by the vegetative stage of the Echinochloa spp.
- To control Echinochloa crus-galli, apply from the phenological phase of 1 leaf to 1-2 brothers.
- To control Echinochloa spp., you can apply the herbicide from the phenological phase of 1 leaf, to 3-4 leaves, but always before twinning begins.
- To control Cyperaceae and other broadleaf weeds, use Viper ON from the 1-2 leaf to 4-5 leaf stage of weeds.

Compatibility:
- Viper ON is compatible with most other rice herbicides.

Recommendation:
- Use Viper ON as soon as the paddy has finished draining and water again immediately 1-2 days after herbicide application.
- Apply Viper ON on dry soil 1-2 days before watering.
- To make sure you benefit from the best selectivity do not treat the crop in stressed conditions such as drought or cold, after disease, pest attacks or nutritional deficiencies.
