Ecological pesticides
Encyclopedia
Green pesticides, also called ecological pesticides, are pesticides derived from organic sources which are considered environmentally friendly
and causing less harm to human and animal health, and to habitat
s and the ecosystem
.
, pesticides are evaluated for minimal adverse environmental effects. Biocide
s include germicides, antibiotics, antibacterials, antivirals, antifungals, antiprotozoals and antiparasites. Pesticides typically come in the form of spray
s and dust
s. Many ecological pesticides are biological pesticides, but others are minerals or chemical compounds.
Although the pesticides and particularly insecticides used in organic farming
and organic gardening are generally safer than synthetic pesticides, they are not always more safe or environmentally friendly than synthetic pesticides, both can cause harm. The main criterion for organic pesticides is that they are naturally-derived, and some naturally-derived substances have been controversial. Controversial natural pesticides include rotenone
, copper
, nicotine sulfate, and pyrethrum
s
However, restrictions on natural pesticides have tightened and as of 2005 rotenone, a dangerous natural pesticide, was not allowed for US organic farmers, and rotenone was not allowed under the California Organic Foods Act of 1990. Phytoalexin elicitor glucohexatose has been called a green pesticide, as has a new class of insecticides called spinosad
which shows "remarkable selectivity" in destroying harmful pests and leaving beneficial insects alive.
