What is one method to improve the uniformity of a spray application?

Spraying twice at right angles is a well-recognized method for improving the uniformity of a spray application. This technique involves applying the herbicide in two passes, with the second pass perpendicular to the first. This approach helps ensure that the spray reaches overlapping areas effectively, reducing the risk of missed spots and uneven coverage. By altering the angle of application, it also helps to mitigate the effects of wind drift and variations in spray patterns, leading to a more thorough and even distribution of the herbicide across the targeted area.

In contrast, simply increasing spray pressure might lead to finer droplets but can cause more drift, while larger nozzles may create a coarser spray that could lead to uneven application. Decreasing sprayer speed can help with coverage, but it is typically more effective to adjust the angle of the spray to achieve maximum uniformity. Thus, ensuring complete coverage through the method of cross-spraying is a strategic way to enhance the effectiveness of herbicide applications.
