i will not post any hazardous pesticide. the bottom of this post will be dedicated to pesticides to avoid.
pesticides should be applied on all surfaces of the foliar plant this means the top of leaves, bottoms, the stems, everything.
i dont recommend spraying any pesticide after day 14 of flower.
Spinosad - brand names: Captain Jack's Deadbug Brew......Monterey Garden Insect Spray
Spinosad - Wikipedia, the free encyclopedia
spinosad needs to be applied 3 times over (at most) 10 day period. personally, when spraying spinosad, i spray one day.....wait two days......spray again......wait two days......spray again. the problem should be eradicated from your plants - NOT YOUR GROW ROOM. insects are tiny and can hide everywhere - the walls, carpets, the dust filter for your carbon filter.....everywhere! to keep them out for good, you need to use a preventative, which brings me to my next pesticide.....
neem/karanja oil/cake (neem oil, neem cake, karanja oil, karanja cake) - brand names: NeemResource.com - a MEGA site for all neem products....Dyna-Gro Neem Oil........Einstein Oil....there are many more........
neem/karanja is a GREAT pesticide, and an even better preventative. This is a great thread that outlines all the benefits of using neem products. Click here if you are interested! Neem oil should be applied right before the lights turn off, otherwise it is useless. Not only is it useless for killing bugs, but it is also harmful to your plants to spray during the "day." I apply a neem spray about every 3-4 weeks (and add neem cake to my soil), and i am proud to say i have been pest free for almost a year.
Pyrethrum - Fox Farm's Dont Bug Me.....Doktor Doom
pyrethrum is derived from chrysanthemums and is considered organic. it has a slight chemical smell, it isnt my top choice, but it works. apply 3 times over a 10 day period thoroughly.
Bacillus thuringiensis - Mosquito Dunks..............Gnatrol
BT is a bacteria that is naturally found in soil all over the world. The bacteria produces insecticidal toxins that kill predatory bugs. BT has little effect on beneficial insects. It has been genetically modified into many plants around the world.....which i am against....but whatever. buying a product ^like posted above is 100% organic - all you are doing is adding bacteria to your soil. it works great against fungus gnats, shoreflies, mosquitos, and black flies.....to my knowledge it is not known to kill whiteflies.
Beauveria bassiana - BotaniGuard ES
Botaniguard contains a fungus - beauveria bassiana - that infects soft bodied insects and kills them. it can even kill grasshoppers it is so strong......it can kill beneficial insects, so it isnt my first method of action, but it works. the disease it gives insects is known as the "white muscardine disease." it is a fungi that is naturally found in soil all over the world.

Metarhizium ansiopliae - Met52 - only pdf.
metarhizum works the same way as beauveria bassiana dies. it caues insects to get the "green muscardine disease."

Mighty Wash - ive never had any experience with it, i have no idea what is in it, but wharfrat74 uses it and i would take his word any day. Mighty Wash
Lavender oil - mix 1 cup of dried lavender per gallon of water. Let sit uncovered in a 5 gallon bucket for 3 days. Stir frequently with a stick. After the third day, you can apply it to your plants at a 1:16 solution/water ratio. apply 3 times within 10 days for maximum effectiveness. the mixture will be good for about a week after the 3 day brewing period. remember to continue to frequently stir until you are finished with the tea.
It's half life is two months, so it will end up in your final product if used. It has been approved for ornamental use only, which means it should not be used on plants for consumption.
Avermectin - Wikipedia, the free encyclopedia -- the chemical used in avid.
anything that says "systemic." systemic pesticides can cause cancer.
****i will add more to the list with insightful feedback pertaining to other products. feel free to chime in!****
