DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) is a naturally occurring hydroxamic acid, a benzoxazinoid. DIMBOA is a powerful antibiotic present in maize and related grasses, particularly wheat and serves as a natural defense against a wide range of pests including insects, pathogenic fungi and bacteria.

In maize DIMBOA functions as natural defense against European corn borer larvae and many other damaging pests.^[1] The exact level of DIMBOA varies between individual plants but higher concentrations are typically found in young seedlings and the concentration decreases as the plant ages.
