THE hand thinning of Japanese plums is the most tedious work which the orchardist is called upon to undertake so that any method of crop reduction other than by hand should be welcome.
Growers may, therefore, be pleased to know that in experiments conducted by the Department of Agriculture several varieties have been successfully spray thinned. The material used was D.N.B.P. (Dinitro secondary butyl phenol).
Spraying with this material considerably reduces but does not eliminate hand thinning.
