Factors Affecting Horticultural Oil Usage

The following factors can affect the amount of horticultural oil that you need to use per gallon of water:

• Temperature: Horticultural oils are more effective at killing pests in warmer temperatures. In cooler temperatures, the oil will not evaporate as quickly and will have less time to come into contact with the pests. As a result, you may need to use a higher concentration of horticultural oil in cooler temperatures.
• Humidity: High humidity can reduce the effectiveness of horticultural oils. This is because the oil will not evaporate as quickly in humid conditions, and it will have more time to come into contact with the pests. As a result, you may need to use a higher concentration of horticultural oil in humid conditions.
• Plant type: The type of plant that you are treating can also affect the amount of horticultural oil that you need to use. Some plants are more sensitive to horticultural oils than others. As a result, you may need to use a lower concentration of horticultural oil on sensitive plants.
• Application method: The method that you use to apply the horticultural oil can also affect the amount of oil that you need to use. If you are spraying the oil, you will need to use a higher concentration of oil than if you are applying it with a wick or a drench.
