I posted a similar question in the plant problem section but nobody answered. Anyone who can help out please do, it would be greatly appreciated. I am having a thrip problem. After talking to "Your Grandfather", who was very helpful, I purchased Azamax. I also decided to purchase mosquito dunks as an economical option to deal with thrips in soil. The plan is to foliar feed with Azamax and root drench with the water treated with the mosquito dunks. My question is two fold: 1) How long should I submerge the mosquito dunks before the bacteria is active enough to eat the thrip larvae in the soil? Is 48 hours long enough, or should I wait longer, and if so how long? 2) I know that chlorine will kill the beneficial bacteria. I have allowed a number of barrels of water to sit for 3-4 days to let the chlorine burn off. I feel that that is enough time, but how long is ideal. I have heard that 2 days is acceptable, but if anyone has any specifics that would be great. Anyone who can help, thank you in advance you are a life saver. I plan on reporting back with my results so that others who face the same challenges will have a valuable resource in their fight against these nasty little bastards. They are easily as devastating as spider mites so beware! Thanks in advance!
