Walking paths are often animated with white lines and arrows showing the wind's direction. In many parts of the film, a man is pacing and spraying properly. There is also a visual of a man checking a pond for larvae with a small white dish on a long stick. Signs on sketched columns are used to show important factors: swath width, concentration, wind speed and direction, air pressure, and movement of the sprayer. The film asserts that these actions, carried out faithfully, will control mosquito larvae efficiently and at low cost."]}},{"label":{"en":["Format"]},"value":{"en":["video"]}},{"label":{"en":["Identifier"]},"value":{"en":["1947 DDT as a Larvicide"]}},{"label":{"en":["Type"]},"value":{"en":["media"]}}],"summary":{"en":["A film instructing on how to create a DDT spray solution, dissolve it before use, fill a spray pump, maintain the pump, and supply spray to ponds.
