Effective grass control: practical experience with Select E.C.

When perennial grasses like couch grass dominate the field, or you are battling barnyard grass in onion or soybean crops, Select E.C. from the French company Arysta LifeScience S.A.S. becomes the tool you rely on at critical moments. This is a systemic post-emergence herbicide that does not just treat the surface; it penetrates deep into plant tissues to suppress the growth point.

Operational insights

As an operator, I can say that working with an emulsifiable concentrate requires precision. The application rate varies from 0.4 to 1.8 L/ha, and it is crucial to consider the weed growth stage: the older they are, the higher the concentration of the working solution should be. The herbicide is selective, allowing for safe use on a wide range of crops — from vegetables (carrots, onions, garlic) to oilseeds (rapeseed, sunflower, soybean) and fiber crops (flax).

• Systemic activity: The active ingredient clethodim is rapidly absorbed by the leaves, making the herbicide rainfast within an hour after application.
• Application flexibility: Post-emergence use allows you to assess actual field infestation before spraying.
• Crop safety: When the regulations are followed (pre-harvest interval up to 60 days), the product does not affect the quality of the final harvest.

An important nuance: Select E.C. is a "single-shot" treatment, as the guidelines allow for only one application per season. Therefore, timing is critical. Apply during the active growth phase of the weeds so that the systemic action of clethodim reaches the roots of the couch grass—this is the only way to ensure the complete death of perennial rhizomes.
