A Secrets of Life short of which the BFI gave this description: "The first part of the film is a speeded-up picture of germination and growth of the tomato plant, ending with the fertilization of the flower and the growth of the fruit. The white flies are then shown in action on the plant, and by skilful micro-photography their life cycle is shown, together with the means by which they injure the plant. A natural parasite—small species of wasp—is also shown in action by means of micro-photography,and its method of parasitism is clearlybrought out. The film concludes with apictorial demonstration of the means forridding tomato glass-houses infested withwhite fly by the use of hydrocyanic gas."
