At Nemaha (table 49), mist nozzles were used for each spray on 
plats 1 and 3 except the petal-fall application, when Bordeaux 
nozzles were used. Practically no difference was found except in 
the amount of spray injury, which was considerably more on the 
penetration plats in the case of both Bordeaux and lime sulphur 
than on the mist plats.
