SPECIFIC USE DIRECTIONS |
|
Aphids Leafhoppers |

1.7–3.4 oz/A |
4.0–8.0 oz/A |
- Codling moth: The use of horticulture oil in combination of ASSAIL has been shown to enhance control of codling moth. - Summer applications may not effectively control psylla - Application to prevent fruit damage from mullein plant bug should be made at pink bud through bloom, prior to petal fall. Do not apply this product when bees are foraging in the area to be treated. |
|
Oriental Fruit Moth Lesser Apple Worm European Apple Sawfly Japanese Beetle |
2.3–3.4 oz/A |
5.0–8.0 oz/A |
- For Japanese beetle: adult beetles will stop feeding after application mortality will occur within a few days. |
|

- Applications for leafminer control must be made before larvae reach the tissue feeding stage. |
|
Apple Maggot Plum Curculio San Jose Scale (suppression) Dogwood Borer |
3.4 oz/A |
8 oz |
- For apple maggot: use of baited spheres is a good indicator that can be used to determine spray timing. - For optimum control of plum curculio, an early petal fall application is necessary, followed by one of two cover sprays during the egg-laying period. - For best results against San Jose scale time applications for the crawler stage. - The addition of horticulture oil is recommended for improved control against San Jose scale. |

Apply sufficient water to provide thorough coverage of all surfaces. - Mealybug: Apply as crawlers/nymphs become active. - Thorough coverage is important to obtain optimum control. - The use of spray adjuvants, such as high-quality non-ionic surfactants, methylated seed or horticultural oils, may enhance coverage and plant uptake and may improve pest control. The use of stickers is not recommended. Some adjuvants can cause adverse effects, such as spotting or burn to fruit or foliage. Select an adjuvant that will be safe for the target crop. Follow adjuvant use directions. |
