Products to improve pest resistance…

    Recently I received an email from a beekeeper who is concerned about reports of caterpillars dying on plants. He said:

    "I read recently that garden centers are offering swan plants that are not receptive to monarch butterflies."

    Then, when I asked him for more details, he said:

    "Further reading of the internet suggests that frequent spraying of plants with "Natures Curator" could repel monarch caterpillars; but I suspect that there is some treatment of the swan plant seed similar to the infamous corn seed treatment."

    Today I’ve had a phone call from someone who has bought new plants from a garden centre and finding her caterpillars fail to thrive, makes me wonder if this product – developed to raise pest resistance in plants – or in fact treated seed is being used by growers.

    What do other people think?
