    Default Chemical burn, what to do?

    Hi All,

    I've been spraying this plant with Safer's End-All (3 times so far) and it looks like I have burnt the new growth with this chemical. Do I snip of the black part and let it grow and see what happens to it later?

    Hi Richard. I would leave it be. Let it naturally do what it will. Others may have other opinions as well.

    Cheers,
    BD

    I agree with BD. There is no sense in stressing the plant more by cutting into it.

    I agree, let it be. Did you let it get in the sun after spraying? That's a sure way to get a burn.

    The black part kept on retreating closer and closer to the rhizome and it has now disappeared into the young p-bulb. Now the young sprout is "mushy" until the red line (see picture). I'm worried it's going to continue to rot and kill the whole plant when it reaches the rhizome.

    When I cut the black part of originally it just continued to get brown and mushy further and further. I'm quite worried now. I don't care about the new growth I just want to keep the plant.

    The browning and blackening started after I sprayed the plant several times with Safer's End-All. I'm guessing that some of the 'solution' got trapped in the crown and messed it all up. (Stupid me for not covering the young one with a plastic bag when spraying).

    Please advise me what to do as the scale I've had to battle has all gone but I'm worried the whole plant might follow into the black hole.

    Thanks.

    Richard, since it has progressed it is probably as you say. Unpot the orchid and cut off that part of the plant down on the rhizome. Be sure to seal the cut rhizome with some pruning spray. Let it dry and then pot the orchid back up. I was hoping it would just stop at the top. Good luck.

    Cheers,
    BD

    I agree with BD . I have found the spray in the blue bottle that says good for 30 days will also cook new growth that was not in the sun ..

    From the picture you can see that it is still green, but I'm not whether or not it will stop at the joint the top arrow is pointing at. The leopard looking wrap is normal for this plant as you can see from the other p-bulb.

    I does seem to look reasonably healthy after removing the mushy black stuff. I'll get the pruning gear ready but it might survive if the rot stops where it is now.

    Will the rest turn black also if it continues to rot or will it just happen internally? This of course is very dangerous.

    Is there anything the plant will do with this stumb if I decide to leave it on (of course if it doesn't continue to rot)?

    Thanks again you guys, I just wouldn't know what to do without your help. It's really appreciated!!
