Maggots on blueberriesAnswered by Julian Posted in Category Pest Control & Nature
I have a blueberry growing in a pot – it is about 4’ tall and heavily laden with fruit this year (it’s about 4 years old).
However, some fruits are fused together and rendered inedible although they do ripen, they don’t swell to the normal size.
Is something enjoying the blueberries as much as I am? I have seen a small maggot on some fruits – could this be the culprit? About a half mm wide and about 5mm long
Is there anything I can do to prevent this pest?
I suspect you may have two different problems. I would give the plant an application of Fruits Boost, a new plant strengthener available from Harrod Horticultural. This will help the roots in the container find any available nutrients and water and help them resist any attack from soil borne pathogens, which may be causing problems. Fruits Boost also contains some biostimulants to give the plant a boost and help cropping. As for the small maggot I think this will be a caterpillar, I suggest you spray the pyrethrum based; Insect Killer Spray on it and any others you find. This kills on contact and is safe to use on edible plants. You can eat the fruit 24 hours after application. I hope this helps.
