The maximum dosages are recommended for soils rich in organic matter and the pre-sowing herbicides should be applied one day before or on the same day as the sowing on the superficial soil layer. Some pre-emergence active substances and their application combinations are mesotrione+S-metolachlor, S-metolachlor+ terbutilazine y dimetenamide-p). The active substances for pre-emergence herbicides are the same as the pre-sowing herbicides. Pre-emergence herbicides should also be applied on the superficial layer of the soil only if weak rains are expected in the ten following days. Regarding post-emergence herbicides, they should never be applied during periods of cold temperatures or water scarcity, as they can ultimately limit yield potential. Nicosulfuron and sulcotrione are post-emergence active substances used against monocots. Bromoxynil, sulcotrione and dicamba+prosulfuron are used to eliminate dicots. The combination of nicosulturon+mesotrione can be used for almost all type of weeds. Mechanical weeding is another weed control alternative that can also be combined with chemical control. Between rows, mechanical weeding can be achieved with standard tools such as field cultivators. I hope this helps.
