Backyard Aquaponics
A place to discuss aquaponics

Hi Royale,
in the hydroponic thread eb mentioned the guy whose hydro farm it was had used natural pyrethrum and it killed his fish...

Guys name wasn't Murray by any chance?

You are mean!

lol, poor murray!

Sunrise girl,thought the guy EB mentioned was using natural pyrethrum but when he switched to synthetic the fish died ?(I`ll have another look to make sure)

Sorry I`ve got it the wrong way around,the guy was using synthetic but when he went to natural he killed the fish.mabey it`s best not to use at all if you can`t afford the loss

Yeah, I'd err on the side of caution myself, and who wants to loose their fishes... especially with LKB around to remind you about it, lol

Might have to own up to some losses shortly - one of the goldies is not looking to healthy at all

I've been searching in vain for a pesticide that is suitable for use with my Marron and Yabbies. They are members of the phylum Arthropoda, which includes insects and arachnids, so anything that harms insects is likely to harm my crays as well.

The answer lies IMO in having your growbed in full sun and elevated off of the ground to discourage crawling insects. Locating the system away from people and pets will encourage birds and frogs that will help you keep the pests down in the system. I am also going to enclose my next system inside a shadehouse which will hopefully keep some of pests out too.

maybe we come back to the flyswat?

Mine is in full sun - except for the 90% shade that the pests give it.

lol - Reminds me of a joke:

If you have a moth ball in the left hand and a moth ball in the right hand, what have you got?







.....a bloody big moth

.....or 90% shade

Les,
I have not tried that method of killing as yet, Les
I am using diatomite on my Tomatoes with some limited success, it is not very good, but better than nothing.
Now that I have had the 100 Silvers in the system for a while the plants are already picking up and I feel the insect problem will diminish a fair bit because of the improved health of the system.

Yeh Muzza, I have noticed a definite improvement in the health of my plants also with the addition of the fish, will be doing a nitrates test this w'end and report the findings
