Aphid control on indoor citrus
We have two lemon trees indoors by the bi-folds.
They are doing well apart from the aphids. From recent Googling the biological controls are not available yet this year. Spraying advice doesn't seem to include Citrus in the UK. Any recommendations? More importantly, anything NOT to use? They can be considered ornamental at the moment because they are showing no sign of flowering. Cheers Dave R |

Unfortunately it is not listed in this country. The only real citrus-related product Bayer list is the Baby Bio citrus food. Presumably citrus growing in the UK is such a minority pastime that they don't brand products for it. Cheers Dave R |

I haven't been able to find any other 'edibles-safe' systemic insecticide. You could either try a contact insecticide or simply try washing the aphids off with a mild detergent solution, as Chris suggested. In truth, even if you just washed them off with plain water you would drown them, making your plant safe and, indeed, you would be safer, too. However, you would probably have to do this fairly regularly to keep the plants clean. -- Spider from high ground in SE London gardening on clay |

You could either try a contact insecticide or simply try washing the aphids off with a mild detergent solution, as Chris suggested. I think it does more than just wash them off. AIUI, the soap solution wets them very effectively, including into their spiracles (breathing holes) and they drown. I think Nick Maclaren recommends adding a dash of meths to the brew for extra effectiveness. I do, but I wasn't the originator. I tend to use soft soap (Savona), which is available from Tuckers, but diluted washing-up liquid with a dash of meths works well, too. They work the same way. It both blocks their spiracles and tends to wash the waxy coating off ones that have it (e.g. mealybugs), which then dessicate. And you can use it immediately before eating the product, and in large quantities (i.e. spray the plants until they are running with it). A few plants are supposed to be sensitive to it, but I haven't had trouble. Regards, Nick Maclaren. |

However, I wasn't aware it was safe for edibles or citrus (which I appreciate is an edible, but may also be rendered sickly by some chemicals), so I was erring on the side of caution. If you know it to be safe for both citrus specifically and edibles generally, then Dave may be happy to use it. -- Spider from high ground in SE London gardening on clay |

I have used it sparingly indoors on an orchid; also I imagine Dave would be using it indoors, so bees would not be harmed in these two instances. However, I believe the toxin takes a long time to degrade so there may be issues with citrus and other edibles, which is why I didn't suggest it to Dave. I'm prepared to be wrong ..

Cheers Dave R Well we've seen a variety of ideas so far:- My thoughts are as follows Most insecticides have a time before harvest, even Organophosphorus was 2 weeks, The chemical of choice in the US is found in Tumble Bug. Whilst the plants are indoors, I'd move them outside to spray if you can, then move them back inside. If you are spraying with anything that may harm bead then don't spray when in flower if possible, or if the plants are not to big then net them for a couple of days after spraying to keep the bees etc. off them.
