The diluted mixture is then sprayed with a coarse nebuliser on the outer surface of the tree ’s trunk and leaves to repel insect pests . The wash push back current infestations of pests and prevent others .

Effectiveness

A study at the Northern Ireland Horticulture and Plant Breeding Station , done to test the effectuality of wintertime washes versus their chemical - based opposite number , found there was no dispute between the contiguous results of the two pest control methods . But unlike many pesticide , some wintertime washes do n’t keep a resurgence of plague and must be reapplied multiple times during a time of year .
