Why Picona?

Picona® is registered for use both pre and post-emergence in a range of spring and winter crops. With effective residual and contact activity, Picona® provides excellent weed control due to the formulation mix of pendimethalin and picolinafen.

Pendimethalin is the key active for grass and broad-leaved weed control in spring cereals and picolinafen provides synergistic post-emergence activity. The different modes of action of the two active ingredients work well against blackgrass resistance. They also provide excellent activity against ALS resistant chickweed and poppy. Picona® will also control a range of other weeds including annual meadow-grass, charlock, orache, knotgrass, speedwell, hemp nettle, shepherds purse and volunteer oilseed rape.

Applying a total of 2000 g/ha pendimethalin from both the pre and post-emergence sprays provides the maximum amount of pendimethalin/ha for the best level of black-grass control and residual activity on any black-grass that has yet to germinate. Picolinafen provides useful contact activity that boosts the black-grass control from the partner grass weed herbicide.

Picona® the perfect tank mix partner

Picona® has consistently performed well in trials when mixed with Atlantis® WG and Unite® (with recommended adjuvants) adding substantially to the control of black-grass from its residual and contact activity.

Picona® supported mixes for black-grass control

It is important to target active weed growth for best results from the post-emergence graminicides, however tank mixes with Picona® are only advised up to the end of February or before lush spring growth commences.

Avoid applications onto frosted crops or where frost is anticipated.

Stomp® Aqua

Stomp® Aqua

Stomp® Aqua contains pendimethalin and is commonly used for pre and post-emergence weed control in a range of crops.

Picona® can be used with Stomp® Aqua as a tank mix partner to gain maximum control.



For the best start in controlling black-grass, annual grasses and broad-leaved weeds, Crystal® herbicide works with residual and contact activity on winter wheat and winter barley crops.
