Petunia infestation


One day my petunias are doing great and the next they’re being eaten by something that has left tiny hard black poppy seed looking “things” all over the leaves. It has eaten ever flower and the ones about to bloom. Do you know what this is and how I can get rid if it? Thanking you in advance for any help. - Susan -

    Hi, Susan,

    If there are holes in the buds, it would be budworms. You can control them with Bt (bacillus thuringensis) or spinosad.

    Budworms love petunias.

    If you find, no holes on the buds, look for aphids, who like to eat tender new growth.

    My guess is budworms.

    Spinosad seems to give the best results for controlling the budworms.
