Oil works by covering or smothering the pest so thorough coverage is essential. Applied as a concentration in the dormant season. Apply 4-6 gallons per 200-300 gallons of water to achieve a 2% concentration. In the summer post bud-break, a more dilute spray of less than 1% (0.75 gallons oil per 100 gallons of water) must be used.

Usage for horticultural mineral oil on Grapes
Dormant to Wooly Bud
| Target | Rate of application | REI | PHI | MOA | Eff. | Notes |
|---|---|---|---|---|---|---|
| Grape Mealybug | 1-2 % v/v | 4 | 2 | UNIM | Apply late March to early April. Direct spray to trunk and main cordons. Do not apply horticultural mineral oil at these concentrations after bud break with green tissue. Sufficient coverage of the trunks, cordon, and early foliage is necessary. 4.0–6.0 gallons per 200–300 gallons water/acre; 1.0–2.0 gallons per 200–300 gallons water/acre when tank-mixed with other pesticides | |
| Scale Insects | 1-2 % v/v | 4 | 2 | UNIM | Apply late March to early April. Direct spray to trunk and main cordons with a thorough wetting. Do not apply horticultural mineral oil at these concentrations after bud break with green tissue. Sufficient coverage of the trunks, cordon, and early foliage is necessary. 4.0–6.0 gallons per 200–300 gallons water/acre; 1.0–2.0 gallons per 200–300 gallons water/acre when tank-mixed with other pesticides |
Wooly Bud to Budbreak
| Target | Rate of application | REI | PHI | MOA | Eff. | Notes |
|---|---|---|---|---|---|---|
| Grape Mealybug | 0.75 % v/v | 4 | 2 | UNIM | May only give marginal control. Post bud-break, a more dilute spray must be used (0.75 gallons per 100 gallons of water per acre). | |
| Scale Insects | 0.75 % v/v | 4 | 2 | UNIM | Apply late March to early April. Direct spray to trunk and main cordons with a thorough wetting. Do not apply horticultural mineral oil at these concentrations after bud break with green tissue. Sufficient coverage of the trunks, cordon, and early foliage is necessary. 4.0–6.0 gallons per 200–300 gallons water/acre; 1.0–2.0 gallons per 200–300 gallons water/acre when tank-mixed with other pesticides |
