Wondering if anyone has sprayed this before? I have been battling with Thrips on and off and while its not the end of the world I hate seeing them just take over during flowering.
Unfortunately spinosad is not available in Canada (I have read this is a labeling issue)… I however was able to find some, which has given me a glimmer of hope to finally lick these bastards!
I have some concern about not kicking the shit out of my plants. It appears whenever I hit them with a pyrethrin or insecticidal soap spray they just take a beating. I always spray without lights on and let them sit to dry before going back under.
Anyone with experience with Monterey Garden Insect Spray? Should I expect my plants to just freak out and get burned up as I have experienced with other products? I have to treat my vegging plants but I do have some that have gone to the flower room that are showing signs of Thrip damage. They have no flower production yet - so I’m not worried there… I just don’t want to beat the shit out of them at this stage.
Take normal spraying precautions - lights out, let dry, etc - but imo it doesn’t affect plants like some other sprays. Don’t spray in flower. You will be happy with it’s efficacy.
Indoor, I turn on a temporary weak fluorescent light, allowing me to turn the main lights off during spraying and drying. (Just dont forget to turn off/unplug the temp light, like I did once.)
I have used it for thrips as both a spray and soil drench. For me, it does cause some moderate leaf damage. It seems to be mainly cosmetic, and the plants seem to do better with fewer thrips.
I’m battling a few myself. This time I got some Captain Jack’s Dead Bug but have also used Monterey.
Just sprayed with Monterey - we’ll see how the tester plant responds. Don’t think it will be an issue. Have some G13HP seedlings showing some thrip damage - we’ll see how tough they are next
How far into flower were you? Spinosad residue tends to stick around because of it’s translaminar properties. In addition to that, there are studies saying Spinosad can be damaging to lung tissue if smoked.
Probably about 5 weeks into flower. It wasn’t a thorough soaking with the spray, I was just trying to get the underside of the leaves more than soaking the flowers.
Spinosad is one of the most extensively used bio-pesticide in the world. The effects of pesticide in human health are mainly associated with its residue in food or occupational exposure in agricultural production. The lung is the direct target of pesticides exposure, although the study of inhalation damage caused by Spinosad remains unclear. The aim of the present study was to evaluate the cytotoxic effects of the Spinosad in human lung cells. We demonstrated that Spinosad could inhibite the proliferation of human lung epithelial A549 cells, induce the DNA damage and enhance the programmed cell death. Intracellular biochemical assay indicated that DNA double strand breaks, cleaved of PARP, release of cytochrome c, decrease of mitochondrial membrane potential, generation of reactive oxygen species (ROS), activation of caspase-3/9, increase of Bax/Bcl-2 ratio, LC3-II conversion, accumulation of Beclin-1, degradation of p62 and the changes in the phosphorylation of AMPK, mTOR are contributed to the toxic effects of Spinosad in A549 cells. The results showed that the cytotoxicity of Spinosad may be associated with the activity of mitochondrial apoptotic pathways or AMPK/mTOR-mediated autophagy. Meanwhile, the DNA stand breaks caused by the Spinosad suggest it has a potential genotoxic effects on human lung cells. We conclude that Spinosad has a potential risk to human health by inducing the cytotoxic effects.
I have used neem and essential oils pretty late in flower with no problems (residues or otherwise). You just have to cut the rate down and make sure it’s emulsified well so you don’t burn the pistils. For thrips, I don’t have a solution for mid/late flower at this time. I really don’t like to spray anything mid/late flower unless I absolutely have to. This is why I think it’s super important to have an IPM program in place.
Integrated Pest Management. Basically layers of pest deterrents. A lot of people will spray, release predators, etc even if they don’t see any problems. Not necessarily at infestation rate, but still hitting them to make their environment is hostile to pests, molds, mildews, etc.
Don’t feel bad @schmarmpit i did the same thing this round. I think I sprayed in week 3 and 4 in flower. But same thing I saw people saying it was safe to use all the way up to harvest, with no effect on flavor. Yikes! Lesson learned. Got to step my IPM game up.
And @man-bot I never had any problems after spraying. Just make sure to do it right before the lights shut off. Your girls will love it. I also use as soil drench.
