Bud Break Sprays
In Australia, mid to late August is the best time for dormant winter oil application. Research in California has shown that the effect of later winter oil applications on bud break is not as consistent. Dormant winter oil sprays should not be applied if there is any bud swell so check your trees before spraying. Dormant winter oil sprays are still worth considering even in good chill years as they may lead to more even bud break. Dormant winteroil sprays are required for control of scale insects.
