    Please help me.

    What is this strange growth on my apple tree trunk and branches.

    There is not a bug inside and it is not on the leaves.

    Thanks.

    "Because eradicating crown gall from infected plants is difficult or impossible, the best recourse for infected plants is to remove and destroy them. The crown gall bacterium can survive in contaminated soil for at least two years, so avoid replanting susceptible plant species in infested sites during this time period."
