Woolly Aphis

Categories: Pests and Diseases of Plants

Will you kindly inform me what you consider the best treatment for apple

trees affected by woolly aphis?



The best way to kill the woolly aphis on the roots is to remove the

earth from around the tree to a distance of one or two feet, according

to the size of the tree, digging away a few inches of the surface soil,

Then soak the soil around the tree with kerosene emulsion, properly

made, of 15 per cent strength, and replace the earth. Be sure you get a

good emulsion, for free oil is dangerous. For the insects above ground

on the twigs, a good spraying while the tree is out of leaf will kill

many, but some will survive for summer spraying, and for this a tobacco

spray may be most convenient.
