Spinosad causing Hermaphrodites?

[mountain]

Appears that spinosad may cause hermaphrodites - anyone else have experience with this?

May not have been the cause, but not really interested in running more "experiments".

Just a couple of bananas on everything, very few really, but even on things that almost never hermie even with photoperiod mistakes, and it only takes one.

Could also have been some of the other ingredients in that particular spinosad product, the timing (applied at flip), or another unknown cause.

Otherwise love the product.

Anyone else have problems with this?

I have been spraying my outdoor plants with spinosad for 3 years (5 or 6 runs now)
No Herms ever

"May not have been the cause, but not really interested in running more "experiments"." Wasn't the cause, spinosad has been used for so long in the garden industry and cannabis. It would be known if it had an effect on hermaphrodites showing.

Did you use the product at an abnormally high dosage?

what was it you were trying to kill with the spinosad?

Never had a problem with this. Been using it for years.

spinosad is def not the cause of herms. If you underwater past week 5 it triples the likelihood that you'll have plants throw bananas, as well as high (78+) temps in later flower. Not saying either of these are gonna cause herms, just make it far more likely they'll appear especially if there's been other problems in the cycle.

I don't recommend spinosad for outdoor use - it's a bee killer.

Mmm... is it? I don't recall the same types of drift warnings for Spinosad (or Bt for that matter) as I do say, pyrethrin/pyrithroid products, or Oxidate, for example. Will have to double-check, because it's that time of year again. Of course, I have an astonishingly large pollinator population, not just honey bees.

:( I know it is...and probably spiders too :banghead: I love spiders
But I have to use it. sorry :meh:

Best thrip solution ever. True Grit turned me on to it in 09 or 10...
Never seen it cause any issues whatsoever.
I didn't know it killed bees, luckily no bees in my grow indoors...

Love that product,,,would look at my nute program ..resently had a herm issue was my nutes to strong.

Well, me being who and what I am (intrinsically curious, fatally so perhaps), I've done a little bit of searching. This is one quote from one abstract I have found specific to Spinosad and toxicity to pollinators.

This research has clearly demonstrated that spinosad residues that have been allowed to dry for 3 hr are not acutely harmful to honeybees when low-volume and ultralow-volume sprays are used. Further, glasshouse and semifield studies have demonstrated that dried residues are not acutely toxic, and although pollen and nectar from sprayed plants may have transient effects on brood development, the residues do not overtly affect hive viability of either the honeybee or the bumblebee. Field studies in which typical application methods of spinosad were used on a variety of crops have demonstrated that spinosad has low risk to adult honeybees and has little or no effect on hive activity and brood development. The collective evidence from these studies indicates that once spinosad residues have dried on plant foliage, generally 3 hr or less, the risk of spinosad to honeybees is negligible.

the bugs like thrips can produce stress that will make shit hermi.. iuno.. usually don't spray anything 2 weeks before flower.. usually will spray wen small. if I have to spray again I do it 3 weks before flower. and then flower out.. hvaent seen a problem.. not sure tho. kuz ive had thrips in flower an sprayed n got hermis. but iunno if its from bugs or spray so I just don't spray unless I g0t 2 weeks before flippin.
