Establishing a Plant Introduction Station and 
Maintaining Germ Plasm Plantings for Horticultural 
Materials at Geneva, New York. To (1) establish and 
maintain a primary regional plant introduction station with 
adequate facilities and personnel to handle introduced and 
domestic plant materials of potential value to the region; 
(2) cooperate with other states in the region, ARS, and with 
other regions in a coordinated program to discover their 
value for plant improvement; and (3) maintain and preserve 
valuable germ plasm of horticultural plants of economic

Influence of Orchard Management Practices on Insect and 
Mite Populations of Some Fruits. (1) Maintain low orchard 
populations of mite pests through selective insecticidal 
rotations to combat build-up of resistance. Study (2) 
beneficial species involved in reduction of populations and 
select insecticides least harmful to species; (3) various 
types of insecticide rotation to learn which is most 
efficient; (4) environmental and cultural factors promoting 
populations of beneficial species.
