and the white trails
and the white trails
I don't know if they re gnats, but what can I do to stop them?
If they are gnats,heres a post by Owderb on what to do mate..
We all come across the little buggers at sometime or another so I thought i'd do a little write up on them.
First thing is that they are more of a nuisance than anything unless you have a really bad infestation.The adults dont really do that much damage,only if you count dumping all over your plants.
Its the larvae if anything that do the most damage,but this is usually with seedlings and young plants where they can puncture the roots which leave the plant suseptable to diseases.They are also known to carry fungal spores,ie pithium etc.
The larvae are quite easy to spot as they live in upper layers of your medium,which includes rockwool and are white,about 5mm long with a shiny black head.When doing nft Ive seen them hanging on to the correx on the underside aswell as being on your tray and in among your roots.
Gnats love dark shaded moist areas thats why they are seen around the base of the plant and are known to be idle fliers.
A way of monitoring the larvae and finding out how bad your infestation is to put a piece of peeled potato pressed into your medium.Leave for around 24 hrs and have a look how many have come to inspect,first in the medium just under the potato,then the potato itself.
Adults can be controlled by putting plenty of yellow sticky traps above the canopy,and horizontally layed on your medium too.The traps also give you a good idea where in the growroom they are more congregated.With them being idle fliers its best to give your plants a shake to get them airborn and give you a better chance of catching them on the traps.
There are plenty of sprays around to eradicate the adults,toxic and natural but to be honest sticky traps are normally sufficient.
The larvae are obviously more of a problem but there ways of tackling them if you have a bad infestation.There are drenches now available to eradicate them but as said before unless they are really bad or are in a treasured mother plants roots then it would be a last resort.
And of course there is prevention which is not always that easy as the eggs may already be in your medium when you buy.All spillages need clearing up and all leaks need fixing as if they find anywhere moist and safe they'll lay there eggs.Screening all your ventilation will also help as this is the main cause of any fliers in your room.
A layer of sharp sand on the top of pots also helps too as it suffocates the larvae and prevents adults from laying their eggs in the medium.Make sure that the sand is washed sand as ordinary builders sand has alot of salt in it and could seep into your roots.
An adult can lay 100-150 eggs in its short life so its important to trap as many as possible
