It didn't hurt my pot plants. It was harsh on one of my houseplants though once. I want to say basil didn't like it.
I have no idea why some people burn their plants with ISO, I don't doubt them either, but I too have never had a problem with 1/1 on a dozen strains. Then I read somebody who burned their plants at 1/3. Maybe I should do a test on some leafs and take some pics.
Anyway, as far as no pest strips are concerned, I use them in veg when the situation is right. For example, if there is just too much vegetation and I know I will never get them all with my pressurized spray bottles, then I'll use the strips. I also Lolli-top in flower and anything leaf material is gone by then anyway. Now that I read it can make me sterile though.....I'll have to use it some more. Got 4 kids, don't need anymore.

Was just looking for that article but still can't find the link unfortunately.
But I did find this post from a study.
Dichlorvos exposure and human cancer risk: results from the Agricultural Health Study.Koutros S, Mahajan R, Zheng T, Hoppin JA, Ma X, Lynch CF, Blair A, Alavanja MC.

OBJECTIVES: We evaluated cancer risk from DDVP (2,2-Dichloroethenyl dimethylphosphate) exposure among pesticide applicators enrolled in the Agricultural Health Study (AHS) cohort. METHODS: The AHS is a cohort of 57,311 pesticide applicators in North Carolina and Iowa, enrolled from 1993 to 1997 and followed for cancer through 2004. A comprehensive questionnaire collected information on exposure to DDVP and potential confounders. Among the 49,762 licensed pesticide applicators eligible for analysis, 4,613 reported use of DDVP. DDVP exposure was classified as intensity-weighted cumulative exposure days (IWED), calculated as [years of use x days per year x intensity level]. Poisson regression analysis was used to calculate rate ratios (RR) and 95% confidence intervals (CI) to evaluate the association of DDVP exposure among 2,943 incident cases of cancer. RESULTS: DDVP exposure was not associated with any cancer studied here. We observed no elevation in risk among lymphohematopoietic cancers, RR = 1.00 (95% CI 0.51, 1.96) and a small excess risk associated with exposure among those with a family history of prostate cancer (RR = 1.18 (95% CI 0.73, 1.82). CONCLUSION: We find little evidence of an association between cumulative lifetime use of DDVP and risk of any cancer at this stage of follow up of the AHS.
Here is some info on this chemical as a carcinogin....
This chemical was proven to be a carcinogen in mice and rats when they were fed large amounts for up to 2 years....
However there have been no studies that show rats or mice will develop cancer thru inhalation....
The abstract above indicates its pretty safe.....
CONCLUSION: We find little evidence of an association between cumulative lifetime use of DDVP and risk of any cancer at this stage of follow up of the AHS.
