Nirvana®
Nirvana® is a herbicide containing pendimethalin and imazamox, for the pre-emergence control of a range of broad-leaf weeds in winter and spring field beans, combining peas and vining peas.
Pre-emergence herbicides are vital for peas & beans
Considering the predicted increased area of peas and beans to be sown this coming spring, it’s well worth a reminder to growers, especially when the pressure is on to sow large acreages, that it is vital to spray the pre-em herbicide as soon as possible after drilling.
- Peas and beans are not competitive crops and so are highly vulnerable to early weed pressure during their germination and establishment
- Post-em herbicide options are basically limited to bentazone (e.g. Basagran® SG)
- The use of pre-em residual herbicides is therefore essential to obtain satisfactory weed control
Nirvana®and Stomp® Aqua are the strongest pre-em herbicide options. They provide early control of a wide range of grass and broad-leaved weeds when applied pre-em to both the crop and weeds.
Pay attention to seedbed quality to get the best efficacy and crop safety
- Good seedbeds and soil structure benefit both crop establishment and the performance of pre-emergence herbicides. Don’t use on water-logged soil or soils prone to waterlogging.
- Fine, firm seedbeds improve seed to soil contact which improves germination and establishment
- Clod free seedbeds also aid efficacy and safety of pre-emergence herbicides
- Drill to a minimum depth of 25mm and ensure seed is fully covered with settled soil
- Level and consolidate loose, cloddy or open tilth before spraying pre-emergence herbicides
- Do not apply where the seedbed is stony, rough, cloddy or open, or when heavy rain is forecast
- Ideally apply within 48 hours of drilling
- Do not apply Nirvana® or Stomp® Aqua once the crop plumule is less than 13mm from the soil surface
Rates and timings (pre and post-emergence options)
Post crop-emergence herbicide options are limited to bentazone
Basagran® SG (bentazone) is the only post-em option for broad leaved weed control. Optimum activity and crop safety rely on application in the correct conditions; bright, warm days with small, actively growing weeds (see product label for advice on application timings and use of split rate applications).
All bentazone products (Basagran SG and others) are subject to the same water stewardship guidelines. Please refer to the bentazone Water Stewardship guidelines at www.agricentre.basf.co.uk/Water-Stewardship/Bentazone-Stewardship.html for BASF’s recommendations for responsible use of bentazone products.
