Dormant Oil Spray


This controls pests on hardy fruit trees. Pests are aphids, thrips, mealybugs, white flies, pear psylla, red spiders and various forms of scale. It also destroys eggs of codling moths, oriental fruit moths, assorted leaf rollers and cankerworms.

1/2 cup fish oil

1/2 cup No. 10 mineral oil

1 cup liquid detergent

2 gallons water

Mix fish oil, mineral oil and detergent thoroughly. Put the water into a bucket and disperse the oil mixture in tiny droplets into the bucket. Pour the liquid into a sprayer.

To use, apply anytime from winter, after all leaves have fallen, to late April, before buds develop beyond the 1/4-inch green stage. Spray on a calm, sunny day with just-above-average temperatures. COVER THE ENTIRE TREE IN ONE SPRAYING.
