Myclobutanil

Myclobutanil is a triazole chemical used as a fungicide. It is a steroid demethylation inhibitor, specifically inhibiting ergosterol biosynthesis.[1] Ergosterol is a critical component of fungal cell membranes.

Safety

When heated, myclobutanil decomposes to produce corrosive and/or toxic fumes, including carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen cyanide, and nitrogen oxides.[2][3]

Banned for Cannabis Culture

Myclobutanil is banned in Canada, Colorado, Washington, Oregon, and Oklahoma for the production of medical and recreational marijuana. In 2014, a Canadian news investigation by The Globe and Mail reported the discovery of myclobutanil in medical marijuana produced by at least one government licensed grower.[4] In September 2019, NBC News commissioned CannaSafe to test THC cartridges for heavy metals, pesticides, and residual solvents like Vitamin E; pesticides, including myclobutanil, was found in products from unlicensed dealers.[5] In Michigan, the current state action limit for myclobutanil is 200 ppb in cannabis products.

gollark: Left-justification:> Left-wing politics supports social equality and egalitarianism, often in critique of social hierarchy.[1][2][3][4] Left-wing politics typically involves a concern for those in society whom its adherents perceive as disadvantaged relative to others as well as a belief that there are unjustified inequalities that need to be reduced or abolished.[1] According to emeritus professor of economics Barry Clark, left-wing supporters "claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated."[5] No language (except esoteric apioforms) *truly* lacks generics. Typically, they have generics, but limited to a few "blessed" built-in data types; in C, arrays and pointers; in Go, maps, slices and channels. This of course creates vast inequality between the built-in types and the compiler writers and the average programmers with their user-defined data types, which cannot be generic. Typically, users of the language are forced to either manually monomorphise, or use type-unsafe approaches such as `void*`. Both merely perpetuate an unjust system which must be abolished.
gollark: Anyway, center-justify... centrism is about being precisely in the middle of the left and right options. I will imminently left-justify it, so centre-justification WILL follow.
gollark: Social hierarchies are literal hierarchies.
gollark: Hmm. Apparently,> Right-wing politics embraces the view that certain social orders and hierarchies are inevitable, natural, normal, or desirable,[1][2][3] typically supporting this position on the basis of natural law, economics, or tradition.[4]:693, 721[5][6][7][8][9] Hierarchy and inequality may be seen as natural results of traditional social differences[10][11] or competition in market economies.[12][13][14] The term right-wing can generally refer to "the conservative or reactionary section of a political party or system".[15] Obviously, generics should exist in all programming languages ever, since they have existed for quite a while and been implemented rather frequently, and allow you to construct hierarchical data structures like trees which are able to contain any type.
gollark: Ah, I see. Please hold on while I work out how to connect those.
