Picona®
Picona® is a herbicide with residual and contact activity for the control of meadow grasses and broad leaved weeds in winter and spring wheat, winter and spring barley, rye and triticale.
Early weed control in spring cereals
- Strong residual activity from Picona® or Stomp® Aqua provides season long control of key spring germinating grass and broad-leaved weeds like AMG, fumitory, poppy, polygonums, chickweed, pansy, speedwells and crane’s-bill.
- Pendimethalin and picolinafen are non-SU, providing different modes of action options for broad-leaved resistance management controlling both ALS-resistant and sensitive poppy and chickweed.
- Picolinafen complements the broad-leaved weed activity of pendimethalin, through residual and contact activity enhancing cleaver and charlock control.
It is often said “residuals don’t work in the dry”. However, if there is adequate moisture for the crop to germinate then there is adequate moisture for the weeds to chit too.
This level of moisture will also be enough for residual herbicides to work. In drier conditions it becomes even more important to keep crops clean to maximise the resources that are available to the crop by minimising weed competition. Pre-emergence applications of herbicides allow this and creates greater flexibility at a busy time of year by keeping crops cleaner for longer. This also prevents complicated tank mixes later in the season when fungicides, trace elements and PGRs may be potentially all applied at once.
Pre or very early post-em sprays are vital to avoid any weed competition with the crop.
Timing is crucial for the best results:
- Spray within 48 hours of drilling
- Ideally, spray on to moist, clod free and consolidated seedbeds
- Ensure the seed is adequately covered by 3.2cm of settled soil
