MILDEW (yçrâqôn, Deu_28:22, 1Ki_8:37, 2Ch_6:28, Amo_4:9, Hag_2:17) is a disease of grain due to various fungi: it is produced by damp, and is in the above passages associated with shiddâphôn, blasting, the opposite condition produced by excessive drought.

mil?dū (ירקון, yērāḳōn; Septuagint usually ἴκτερος, ı́kteros, literally, ?jaundice?): In the 5 passages where it occurs it is associated with shiddāphōn, ?blasting? (Deu_28:22; 1Ki_8:37; 2Ch_6:28; Amo_4:9; Hag_2:17). In Jer_30:6, the same word is translated ?paleness,? the yellow color of one with abdominal disease. The root-meaning is ?greenish yellow?; compare the Arabic yarḳān, meaning both ?jaundice? and ?blight.? Mildrew or ?rust? in grain is due to a special fungus, Puccinia graminis, whose life is divided between the barberry and cereals. Many other varieties of fungi which flourish upon other plants are also designated ?mildew.? See BLASTING.

Mildew
(יֵרָקוֹן, yerakon', greenness, i.e., pallor, as the paleness by affright, Jer_30:6) is properly a species of fungus or parasitic plant generated by moisture, and corrosive of the surface to which it adheres. In Scripture it is applied to grain, and refers to the pale green or yellowish color indicative of fading or withering of plants (Deu_28:22; 1Ki_8:37; 2Ch_6:28; Amo_4:9; Hag_2:17; in all which passages it is connected with blasting). The Arabic applies the word yerakon to human beings as well as to corn, and thus describes the disease called in Europe yellow jaundice. Forskal was informed in Arabia by a Jew that it was the general opinion there that it is a mild breeze, dangerous to the corn, by which the ears are turned yellow. SEE LEPROSY.
