Not going to argue with you. Manufacturer PHI for grapes is 14 days. Its likely pointless to debate this point further if you would knowingly eat grapes that have been treated less than 14 days prior to harvest.

Rethink your grow-op and start over.

Not sure what you are talking about to be honest, perhaps you made some incorrect assumptions.

I am happy to buy fruit from Tesco (grapes) even if they had been treated with myclobutanil
since this has been approved and licensed to be used in this industry

i am aware some hippies and conspiracy theorists would perhaps fear many fungicide/pesticides
and believe the governmental regulations controlling their usage are not stringent enough or perhaps the agent is carcinogenic or something

i would not use any of these products outside the guidelines of use
which are printed on the label

peace

Human Health Effects
Myclobutanil has a relatively low acute toxicity. The acute oral LD50 for mice is 1360 mg/kg, and ranges from 1.75 to 1.8 g/kg for rats. Myclobutanil metabolizes into 1,2,4-triazole, which has a lower acute toxicity than the parent compound (#EPA).

Workers exposed to myclobutanil have reported symptoms such as skin rash, allergic dermatitis, itchiness, nausea, heachache, diarrhea, abdominal pain, vomiting, nosebleed, and eye irritation (CDPR).

In a two-generation study on rats over the effects of myclobutanil on reproduction, researchers found a decrease in pup weight gain, increased incidence of stillborns, and atrophy of the testes and prostate (#EPA). Myclobutanil is listed as a developmental toxin in the Toxics Release Inventory (#PANNA).

Chronic toxicity tests on rats found decreased body weight and changes to brain and spleen weight, in addition to reproductive effects (#EPA).
