Problemas?/Problems?

Esta é uma das amoreiras que plantei. Aparentemente está tudo bem com ela, começou agora a crescer depois do repouso invernal. Hoje de manhã quando andava a dar uma volta pela horta reparei que na parte de baixo das folhas apareceram umas manchas alaranjadas. Não sei o que são nem se são alguma coisa preocupante, só sei que estão lá. Alguém por ai neste grande cibermundo me pode dizer o raio é isto, e o que tenho de fazer para o eliminar?

I was checking things in my vegetable garden this morning when I noted something strange under the leaves of one of my blackberries bush. There are lots of little orange dots underneath the leaves. I'm not sure what they are, if they are anything at all. Should I get worried bout them? Should I do something about them? Should I let them be? Can any of you, garden bloggers, help me on this one?

Looks like your Blackberry might have Orange Rust. From what I have read Orange Rust is not good and once the plant is infected it should be destroyed.

It's rust, which is really a mold. One of my rose bushes usually gets some rust on the undersides of its leaves in spring when I don't water it enough. I try to cut off all rusty leaves and give the bush a good soaking.

But you can also buy all kinds of sprays and fungicides if you want to go that route. Some people advocate a dilute spray of what we call baking soda in the US--sodium bicarbonate. I've never tried that.

Best practice is to bring a trash bag in to the garden so the leaves go straight into it without passing through the garden and contaminating other plants, and wash your pruners with dilute bleach or alcohol.

In my experience, minor rust infestations aren't a big deal. I get them every year.

Good luck!

Vanillalotus is right. It's probably worse than I thought for your blackberry.





"In other areas of the world, the rust can reduce the foliage by as much as 50% in a five-year period. The inability to hold onto leaves and the vulnerability of new growth can severely inhibit blackberries’ usual talent for prolifically producing daughter plants and new suckers."

Blackberries are very tough. I bet you will still have some.

I had same thing happen to mine when I bought a new sort of Blackberry to make friends with the others in my garden. Unfortunately, it brought orange rust and since it's a fungal disease which spreads through the plant and grows into
plant crowns and roots and remains in the plant for life, I had to remove and destroy all of the infected plants, and it also took one black raspberry plant with it. The bad thing about it is that once a plant is infected, it’s infected for life, without a cure. Annoying!

You might get blackberries but they won't be as big or as many. You can still keep it but if you have other blackberries it's better to destroy that one before it spreads. The plant will still live but after a while it will decline and die.

Thank you everybody for your comments and advices. I was reading a bit about orange rust and realized vanillalotus was absolutely right (thanx vanillalotus). It was indeed orange rust and the best solution was to destroy the plant before it infected the other one I have. It was really a difficult thing to do because this plant was a Christmas gift but it had to be done. And so it was, the diseased plant was pulled out and destroyed. Hopefully the other blackberries bush wasn't contaminated.

Ora vamos lá estrear os comentários em português...
De início pareceu-me uma espécie de pulgão amarelo que já tive nas minha Hoya. Tinha ideia que a ferrugem era uma coisa dentro da folha, isso parece poisado na folha. De qualquer maneira tirar as folhas afectadas é sempre mais prudente mas, se forem muitas, lá se vai a planta. Talvez limpar e desinfectar com um antifúngico. O bicarbonato de sódio não sei o que faz mas de qualquer maneira desinfecta. O meu pai mandava-me gargarejar com isso quando tinha dores de garganta, quando era miúda (ele era médico).
Gostei muito de ver o blog, é sempre um prazer passear por aqui.

Fiquei roídinha de inveja dos brinquedos. Ainda não comprei nada disso porque tenho um terreno muito pequeno e seria ridículo. Mas,cada vez que preciso de cavar ou arrumar os ramos da poda penso no jeitinho que me davam. Outro brinquedito engraçado é aquele aspirador/soprador de folhas. Todos os Outonos me apetece um.

ana maria b, há muito tempo q não se deixava v(l)er. Obrigado pelo comentario mas o assunto já teve um final definitivo. A planta foi arrancada e destruida. Tratava-se realmente de ferrugem das amoreiras. Um tipo particular de fungo q ataca estas plantas. Neste caso trata-se de uma doença sistemica e não de uma afecção das folhas, como nas roseiras. Não tem cura e a planta acaba por morrer. Antes q me contaminasse as outras optei por a destruir. Espero ainda ter ido a tempo.
