Products for Post-Emergence Weed Control in Maize

Wing-P is a new herbicide for controlling broad leaved and grass weeds from BASF

Wing-P combines two complimentary active ingredients (dimethenamid-P and pendimethalin). The product is best used at the pre-emergence timing but if weed control is delayed (for example by the inability to spray due to weather conditions) it can also be used early post-emergence of the crop.

The dual activity of the two active ingredients in Wing-P increases the range of weeds that the product is effective on and also increases the activity of the herbicide against certain weeds compared to straight pendimethalin products.

Late Emerging Weed Populations Can Cause Significant Impact On The Yield Of Grain Maize

In addition to excellent early weed control, Wing-P also provides residual control of weeds through to the later stages of crop growth. This ensures that the yield potential is not compromised by later emerging populations of weeds. The effect of later emerging weeds on maize yield potential is shown in the chart below.

BASF Recommendation for Weed Control In Maize

• Apply 3.2 litres per hectare of Wing-P pre-emergence of the crop.
• Where there is a risk of heavy infestations of weeds apply 4 litres per hectare of Wing-P pre-emergence of the crop.
