Beneficial Dormant Oil

March 12, 2019

WHAT’S GOING ON IN THE FOREST?

Maple sugaring season may be underway or in fact waning down as temperature-forecasts show a warming trend in central Ulster County. However, once temps remain above freezing consistently for a couple of days marks the time to spray dormant oil on your apple and pear trees. Advantages of using dormant oil (according to Illinois Extension) are: “(1) a wide range of activity against most species of mites and scales, including some activity on eggs; (2) minimal likelihood of insects’ or mites’ developing resistance; (3) generally less harmful to beneficial insects and mites than other pesticides; & (4) relatively safe to birds, humans, and other mammals.” The disadvantages can be improper timing or rate which can cause damage to leaf-tissue; Just read the label. Hopefully this growing season won’t be as rainy as the last one.

 

May the forest be with you,
