Gnatrol offers highly selective, effective control of fungus gnat larvae, especially for those growers concerned with worker safety, the environment and resistance management. Regular follow-up applications using the suggested light infestations rates, will establish a long-term maintenance program. A LD50 study (by definition is going to kill half the test animals) is not an appropriate indicator for health effects if a normal dosage is expected.

I just wanted to mention my positive experience using Gnatrol (a biological control [Bacillus thuringiensis] for fungus gnats). t. to species of several invertebrate taxa (Acarina, Nematoda, Collembola, Annelida, Hymenoptera) inhabiting the soil has been demonstrated, but only rarely is it possible to relate dosage information to field situations, and in many cases the B. While they do a great job of trapping adults they don't seem to be stopping new larvae (remember that it just take one gnat to get through the perimeter alive to lay 200-300 eggs). Valent Gnatrol OMRI gives you a way to target gnat larvae and keep your young plants healthy through maturity. ounce of Gnatrol concentrate will make 4 gallons at the active pest control rate of 3 tsps per gallon.EPA Memorandum: Review of ecological non-target insect studies for Bacillus thuringiensis Cry3Bb1 protein. These spores and crystals must be ingested by the immature feeding stage of development (larval) of insects to be effective . But after reading more about it, Bti is as close to a miracle fix as modern science has come up with.

Because it's a bacteria that's found naturally in soils anyway, there's less fear of using it than more dangerous chemical solutions. I know I had springtails in there when I first set up the tank earlier in the year, but don't see them anymore. Important: Gnatrol WDG should not be injected in combinations with fertilizers or fungicides containing copper or chlorine, as this may neutralize the active ingredients. You can use Gnatrol OMRI in greenhouses and various interior plantscapes to protect ornamental and vegetable crops. The best way to deal with insects is to use clean soil, don't overwater, and use other preventive measures.Organic and systemic pesticides for the most common indoor, outdoor and greenhouse pests: Fungus Gnats, Whiteflies (Silverleaf, Sweetpotato, Banded-winged, Citrus, Giant), Spider Mites, Broad Mite, Tomato Russet Mite, Pacific Mite, Two spotted, Strawberry, European Red, Clover, Southern red, Spruce, Bamboo, Lewis mite. I finally have them under control in my houseplants using Gnatrol ( bacillus thuringiensis ) a bacterial larvicide, and am working up the nerve to use it in the millipede tank. Does anyone know if gnatrol (aka mosquito bits, aka bacillus thurigiensis) is safe to use with isopods and springtails? I've admittedly been resisting this option because I've heard that Gnatrol is a "pesticide", and I wasn't keen on adding "dangerous chemicals" to my plants.

My hope is that eventually I'll go weeks without seeing one gnat, and then I'll finally be able to properly repot and fertilize this plant and hopefully see it grow again.EFFECT OF BACILLUS THURINGIENSIS ISRAELENSIS (H-14) ON THE ISOPOD ASELLUS FORBESI AND SPRING AEDES MOSQUITOES IN MICHIGAN (1989) -- " We conclude from our data that isopods in treated pools were not negatively affected by the B.
