Residues

Use

Used against broadleaved weeds and grasses; sprayed outside on fields of wheat and other small grain cereals, vegetables including beans and peas.

Alternatives

The alternative is mechanical weeding, widely available, e.g., using mechanical harrows and camera-guided mechanical hoes. Heating is another option. This can be done easily before planting and - with some experience - in and between the rows. Crop rotation also helps preventing dominant weeds to accumulate.
