mixing lime sulfur and oils
in your publlication "Mnaging diseases and inse
cts in home orchards" EC631 April 2015, page 2 footnote 5 says mixing sulfur and oils can cause damage to plant, but page 5 Pears, Postharvest recommends oil and sulfur. What damage and on what plants will mixing the two cause damage?
Douglas County Oregon
Damage would result when applied at bud stage. If the mixture is applied during the dormant season (November to February) you should be safe to mix the sulfur and oils.
Hope this helps.
