The RHS web site says:-
I searched on here and sort of got the impression that grease bands (bands of grease) may not be worth while so can I ask please:-
1. Are grease bands or a band of grease worth doing even though they are no 100%?
2. When do they need to go on, as I've found dates as from beginning of September to end of October?
3. Is there any reason not to just use "axle grease" as I already have a gun full of the stuff? How wide do the bands of grease need to be?
4. Do I need to do plums and damsons?
Thanks.
Grease bands are mainly used to protect fruit trees, such as apple, plum, pear and cherry. Note that sticky barriers give no protection against codling moth, the cause of maggoty apples. That pest has winged females that are active in midsummer.
Mottled umber moth (Erannis defoliaria), winter moth (Operophtera brumata) and March moth (Alsophila aescularia) have wingless females which, after emerging from the pupal or chrysalis stage in the soil, must climb the tree to mate and lay their eggs. The caterpillars of these moths eat the leaves of many deciduous trees and shrubs during late March and early June.
Grease bands trap some of the wingless females before they reach the branches. Winter moth is the most important of these moths and it emerges as adults during November to mid-January.
