Dormant spraying using Vegol?

I've been doing using Vegol (canola oil-based) for dormant spraying, and I've noticed that they give the same mixing instructions on the label for dormant and non-dormant spraying (2% or 4 teaspoons per quart of water, or 2 fl. oz. for 3 quarts of water). This is unusual, since non-dormant plants are usually much more sensitive to oil.

Is this working for those of you that use Vegol? Or do you have your own recipes for dormant and non-dormant spraying? I don't want to use petroleum-based horticultural oil if I can avoid it, so I'm really wondering about how much sense it makes. It seems to me that the above dilution might either be too strong for non-dormant plants, or not strong enough for dormant ones, or maybe not *smile*?

Thanks.

Depends on the plant as to whether it is sensitive to an oil spray or not, and also the weather--oil sprays are used by rose gardeners for powdery mildew infections year round, provided conditions are cool.

Dormant spray, I use copper.
