Herbicides prior to emergence and early herbicides after emergence are widely used to control weeds in corn in Europe, where glyphosate-tolerant weeds are not registered. Among all these herbicides, there are major differences in the real life of the activity, the water solutions, the listing of leaves and other characteristics. The times of application of specific herbicides must be redefined, depending on the weed spectrum, the current moisture in the soil and the absorption capacity of the herbicide. The constant presence of wind in the intensity of 2 to 8 m / s, especially in the Banat area, complicates the application of pesticides. An obvious problem on the plots in Banat is a large deviation in the microreleaf. As a result, the application of pesticides is problematic every year because uniform distribution of herbicides is not achieved on the surface. Using suitable sprayers allows better pesticide applications. A better application involves increasing the amount of herbicide deposits on the target surface, which leads to an increase in the efficiency of the application. Adequate use of the sprayer can increase the amount of deposits doubled, which implies dramatically higher application efficiency.
