Bad reaction to pyrethrum?

The general measure of poisonousness is the LD50. This is the dose at which 50% of test subjects die. Note, these figures are for rats... all LD50's are given for rats because we can't ethically kill hundreds of people to generate statistics.

Overview

 

Piperonyl butoxide is a synthetic insecticide synergist that was developed in 1947. It is combined with other pesticides such as pyrethrins, pyrethroids, rotenone, and carbamates to enhance their effectiveness. It does not have insecticidal qualities on its own (NPTN). Piperonyl butoxide mixtures are often used on food crops and livestock. It is also found in a wide range of household insecticides including sprays and lice treatment shampoos.

 

NIOSH). In soil, piperonyl butoxide has a half-life of 73 days (EPA).

Because it is always combined with various insecticides, piperonyl butoxide is available in many forms, including aerosols, liquids, ready-to-use solutions, dusts, wettable powders, pressurized gases, pressurized liquids, dilutable concentrates, shampoos, towelettes, and water-based concentrates (EPA).

EPA).

Piperonyl butoxide is sometimes used in conjunction with agricultural pesticides. It can also be found in animal ear tags for livestock, pest strips, and in some veterinary pesticide products (NPTN).

Piperonyl butoxide may be found in residential products for use in gardens, lawns, and ornamental plants. For indoor settings, there are sprays, dusts, and foggers. Some products are also designed for direct use on human clothing, bedding, and mattresses (NPTN). Piperonyl butoxide is also combined with pyrethrins in human medications to treat scabies and lice infestations (Medline).

EPA classifies piperonyl butoxide as a group C carcinogen, a possible human carcinogen (EPA).

People can be exposed to piperonyl butoxide by ingestion or inhalation. Ingesting piperonyl butoxide may cause vomiting and diarrhea (PANNA). Dermal tests on rats indicate that the compound may cause redness and swelling (NPTN).

NPTN). The EPA determined that piperonyl butoxide degrades somewhat rapidly in the environment, and therefore has a moderately low chance of contaminating water sources (EPA).

In mammals, piperonyl butoxide is only slightly toxic. The LD50 of rats is 4570 mg/kg. It is moderately toxic to fish, but it is highly toxic to other aquatic organisms and amphibians. The LC50 is 1.9 ppm in rainbow trout, 0.51 ppm in waterflea, and 0.21 ppm in Western chorus frog tadpoles (EPA). It has a low toxicity in birds (NPTN).

Precautionary Notes

 

Use piperonyl butoxide products very carefully around water sources to avoid contamination. Piperonyl butoxide is always mixed with other pesticides. Understand the risks associated with all other active ingredients.

Thanks again guys/gals,

Haratio mega info cheers man. Poison for sure i will not be using it. Rest assured :peace:

 

Hi Louise, i only added monsta bud to nutes not foilar feeding so i dont know what happened there Ph maybe.

well they are looking a bit better again today so hopefully rebounding. Been reading some forum topics on defoiliation so maybe i've increased the yield potential :yahoo: gotta be a positive somewhere!

 

Cheers all :bongon:

Yeah poison for sure, but if we checked out all them chemicals we ingest daily we would be shocked. I could imagine the above chemical being more dangerously than McDonald's. That shit is poison and will give ya cancer, if obesity doesn't get to ya first.

Monsta-bud isnt a growth hormone its a fucking concentrated bloom nutrient ... i'm confused ... if you sprayed your plants with it it's likely they will burn ... if it wasnt diluted sufficiently .... not a bad nutrient i must add .... wouldnt use it as a base nutrient but a decent once every few weeks additive ... it does have some organic goodies in it ....

 

just my worthless 2 cents,

 

peace.

I have used Pyrethrum for over 30 years and have never had a bad reaction from it. Burn looks to me like wet foliage under strong light.

Cheers.
