Smith, Extension Field Crops Pathologist, University of Wisconsin-Madison. Herbicide half-life estimates are derived for the WSSA Herbicide Handbook and other scientific literature.2Common small-seeded legumes include alfalfa, clovers, and hairy vetch.3 This herbicide does not have soil residual activity at normal application rates. [10][11], Since the 1970s, multiple countries started to limit or ban the aerial application of pesticides, fertilizers, and other products out of environmental and public health concerns, in particular from spray drift. The extra drops per square inch can improve performance of a contact pesticide (impact only what they land on).

Chemicals can also be sprayed on crops such as sunflowers to hasten the drying process for harvest. However, this level of yield gain only materializes when a yield limiting foliar disease is active and moving up the canopy.

Many farmers routinely spray their crops with pesticides, but can neighbours demand their concerns be considered?
