What is a wiper application in pesticide application methods?

A wiper application refers specifically to the method of applying pesticides using a rope-wick device, which is designed to minimize contact with desirable plants while effectively treating weeds or unwanted vegetation. This technique allows for the targeted application of herbicides, as the wicking action of the rope delivers the pesticide directly onto the leaves of unwanted plants that come into contact with it.

This method is particularly useful in scenarios where precision is necessary, such as in areas where crops and weeds are growing close together, as it helps to reduce the likelihood of chemical drift and minimizes the risk to non-target plants. The design of the wiper application system ensures that only the intended target is treated, making it an efficient and effective method for managing weed populations without harming surrounding plant life.
