[KAPOW]

Thankyou everyone for the help. Does anyone know of a good hydro shop in Brisbane to buy this stuff & get help for anything else.

pest strips around the base of the plants ...... gnat off (BT) after a decent feed of neem (over a 2 day period)..... reapply gnat off 3 days later 3 or so more times over 9 days or so and reapply neem once a week, break their life cycle..... can also use chilli/garlic as a deterrent - sprayed onto soil surface to deter adults from laying eggs ..... reapply in a week afterwards ... same as initial 9 day application .... depending on whether or not you have identified possible contaminations of gnats in grow medium .....

My local hydro shop has satchels of stuff called Alstystin. 2 grams per 10litres watered through the growing medium or mixed in the nutrient tank kills eggs ,larvae and adult flies in one hit. Its dynamite.

Frequently Asked Questions

 

Q: How does Alsystin work on sciarid fly?

A: Triflumuron, the active ingredient in Alsystin, interferes with the formation of chitin "the skin layer" of larvae which causes defective formation resulting in larval death. Alsystin does not control adult sciarids as they do not moult; however, only the larval stage is responsible for effects on yield or quality. Adults do not disappear immediately after treatment with Alsystin.

Q: Is Alsystin safe to beneficial organisms?

A: Since the contact action of Alsystin is fairly limited, the potential for major damage to beneficial organisms is highly unlikely. Extensive tests both in the laboratory and in the field have shown that Alsystin has little or no effect on important beneficials.

Q: Is Alsystin safe to the user and consumer?

A: From acute studies the specific mode of action of Alsystin results in the product being regarded as non-toxic to man, other mammals, birds and fish. The results of all studies demonstrated that Alsytin is a product with extrememly low toxicity for users and consumers.
