Abstract
AbstractMany synthetic pesticides (herbicides, insecticides, fungicides, etc.) can be complexed with cyclodextrins. This “molecular encapsulation” frequently results in advantageous modifications of the properties of complexed substances.The hydrophilicity is strongly reduced, i. e. wettability, rate of dissolution and extent of solubility is enhanced, which generally results in enhanced bioavailability.Volatile, liquid, and gaseous substances, or substances of intolerable stink can be converted into microcrystalline, stable, well formulable substances.Incompatible substances can be mixed when at least one of the reacting components is complexed.The selectivity between herbivorous/non‐herbivorous insects toxicity can be enhanced.CD‐complexes areper semicronized substances, they are easily dispergable, no electric charging was observed.Long lasting effect can be ensured (e. g.in soil) because the complexed substances are released only on contacting with water.Cyclodextrins exert a direct auxin‐like effect on plants therefore phytotoxic effect of pesticides can be reduced,etc..
