Fungus gnats

[ross]

I got gnats pretty bad and I've been using tanlin but it's too expensive so I got gognats and it doesn't have any soil directions on the bottle. I wanted to give it to them tonight does anyone have any pointers?

I use Diotose Earth (sp)...I mix in a tablespoon in the top 1/4 inch soil.and bottom feed for few runs...this what I found when googled the product

:yeahthat: they can be annoying---but should not be damaging your plants---

If the gnats get bad enough they will damage the roots of the plants. I use Azamax and drench the soil about once per grow during the first couple weeks of the flowering cycle. I have also found that the yellow "sensor" sticky cards work great for reducing the flying critters.

Thanks 4u2. Gave them 2 tbsp per gal half strength tonight. There were like weird fibers in it.

Adult fungus gnats, shore flies, moth flies, and March flies primarily are a nuisance. March flies, for example, are so named because adults of some species appear in large numbers during spring and fly to windows or porch lights. Adults may swarm along roads, annoying motorists by fouling windshields. Although March flies can enter buildings, they do not reproduce or develop in buildings. Fungus gnats and moth flies, however, can both enter buildings as flying adults and develop indoors through all life stages. Shore flies are unlikely to reproduce indoors, except in greenhouses. Fungus gnats, shore flies, moth flies, and March flies do not bite people or animals and, in the United States, are not known to carry human pathogens.

Only fungus gnats commonly damage plants. Larvae of these flies feed on roots, thus stunting plant growth. Root damage can occur in interior plantscapes and in houseplants if high populations infest moist, organic-rich soil. Fungus gnat larval damage can be especially serious in greenhouses, nurseries, and sod farms. In addition to larvae chewing on roots, both larvae and adults can spread plant pathogens and may promote disease in commercial crops.
