CHALLENGE 600 SC

Challenge 600 SC is registered for the control of annual dicotyledonous weeds and some annual monocotyledonous weeds. The active substance aclonifen acts on weeds by inhibiting two enzymes involved in the synthesis of chlorophyll and carotenoids. The uptake of the active substance is via coleoptile, hypocotyl, cotyledons and leaves when the weeds are emerged at the time of application. The efficacy of the active substance aclonifen is ensured by the persistence of the product, which varies between 1.5 - 2.5 months, depending on climatic conditions and soil type.

Number of treatments on all crops: 1 treatment per year/crop. Water volume for all crops: 200-400 L/ha.

Control spectrum: Sythrus (Amaranthus spp.), rapeseed samulastra (Brassica napus), trailing-goatweed (Capsella bursa-pastoris), wild spinach (Chenopodium album), smokeweed (Fumaria officinalis), turnip (Galium aparine), stinking suet (Lamium purpureum), chamomile (Matricaria spp.), creeping clover (Mercurialis annua), wild poppy (Papaver rhoeas), troscotch (Polygonum aviculare), climbing buckwheat (Polygonum convolvulus), frog's pepper (Polygonum persicaria), wild radish (Raphanus raphanistrum), wild mustard (Sinapis arvensis), rocoine (Stellaria media), susai (Sonchus asper), ventrilica (Veronica spp.), three-spotted fritillary (Viola arvensis) and some monocotyledonous weeds such as foxtail (Alopecurus myosuroides), meadow meadow (Digitaria sanguinalis), bearded grass (Echinochloa crus-galli).

Restrictions: Do not exceed the recommended dose. Do not apply treatment on very hot days with strong sunshine, but only in the morning after dew-drying of the plants or towards evening. Do not treat if negative temperatures are expected at night. Avoid spreading solution on neighboring crops during treatment. DO NOT herbicide when wind speed exceeds 5 m/s to avoid drift of solution onto neighboring crops.

* Caution! For sandy soils or when heavy rainfall is forecast after sowing, it is recommended to apply Challenge 600 SC herbicide post-emergence in 2 stages: 1 L/ha and, about 10 days later, a second treatment of 1.5 L/ha, and no later than 2 to 4 true leaves.

Break to harvest: onions, shallots, celery, fennel, fennel, dill, dill, Jerusalem artichoke - 90 days, carrot and parsnip - 70 days.
