Locusts are so hooked on green that when they got into the garden centre nursery over where I shop, they took to the Yukka leaves but only ate the green in the centre, leaving the yellow band on the edge of the leaves. They say that they will try and eat green shade cloth, even green plastic. I would just hope that plants dusted white might be unattractive to them. Derris dust would be better as that is designed to kill certain garden pests. I think bees would still come for the flowers and be safe. As a friend said, we'll have to pray for strong northerly winds when they take to flight, so they blow on right by.
