    For the last couple of months I thought I was fighting spider mites until today I saw on your site that it was not spider mites but whiteflies. I have been using Bonide All Season Horticultural Oil and it’s working, but it’s turning the leaves dark, dark green and curling up the tips.

    What I want to know is this product killing my plant or will the plant be able to shake it off and live. I have a lot of money tied up in these plant and if the stuff I used is killing my plant can you tell me what I can do to turn it around and save them.

    Please contact me with good or bad news so I will know what to expect and should I pull the plant up or do something else. I’m in a hell of a mess and your my only hope.

    Hi Gwendolyn –

    Yes, All Season Horticultural Oil works on many plant pests — including whitefly — by smothering the insects, but keep in mind that how and when you apply the product makes a big difference on how well it works and the health of your plants.

    โ€ขย Use 1.5 – 4 Tbsp per gallon of water and apply once or twice weekly, depending on growth and insect pressure.
    โ€ข All Seasons Spray Oil is most effective on whitefly during the immature stages.
    โ€ข Do NOT apply when temperatures are above 90หšF or when plants need watering as it may shock plants and cause leaf drop.
    โ€ข Leaf burn may be affected by the quantity of oil used and temps at the time of application.
    โ€ข Do NOT exceed the maximum rates or apply more often than indicated on the label.
    โ€ข Use caution on open blooms — bleaching and spotting may occur.
    โ€ข Certain plant species may be more sensitive to oil.
    โ€ข Give special attention to underside of stems, leaves and limbs.

    Please refer to the product label for specific mixing instructions.

    Hope this helps!
