What technique involves applying pesticide in parallel strips or bands, such as between or over rows of crops?

The correct answer is the technique of applying pesticide in parallel strips or bands, which is known as band application. This method targets specific areas, such as the space between or over rows of crops, allowing for effective pest control while minimizing the amount of pesticide used. Band application focuses on the crop zones where pests are more likely to occur, providing efficient control while reducing the impact on the surrounding environment. This selective application can also lead to cost savings and lower risks associated with pesticide runoff.

Other options, while related to pesticide application, serve different purposes. Basal application typically refers to applying herbicides around the base of plants or trees directly, rather than in strips. Broadcast application involves spreading pesticides uniformly over a larger area without focusing on specific rows, often leading to a higher total pesticide usage compared to band application. A jar test is a laboratory procedure used to determine the compatibility of different pesticides or to assess their effectiveness, not a field application technique.
