Scheduling plot plan

Scheduling The plot plan is -used to schedule the orderly completion of engineering activities. 

Construction The plot plan is used to schedule the ereaion sequence of all plant equipment, which includes rigging studies for large lifts, constructibility reviews, marshaling, and lay-down areas throughout the entire construaion phase. 

Spray schedules applied on experimental plots at the Yakima, Wash., and Vincennes, Ind., laboratories of the United States Bureau of Entomology and Plant Quarantine were studied to determine the magnitude of parathion and DDT spray residues at harvest. The parathion sprays were prepared from 25% vet table powder and the DDT sprays from 50% wettable powder, except in one series of tests, when a 25% DDT wettable powder was used. All spray treatments were planned and made by members of the Division of Fruit Insect Investigations. Conventional hydraulic sprayers were used in this work.
