1387. Cony, Ann. unknown. First of kind natural herbicide reported.. Sacramento Bee (newspaper).
Richard W. Jones, of UC-Berkeley, reported the use of a natural, self-destructing herbicide capable of killing a wide variety of weeds. It is made from a common soil fungus Gliocladium virens which is artificially charged with nitrogen, thus causing it to produce a compound that is toxic to plant roots for about 2 weeks. The herbicide can kill plant roots as well, but it doesn't hurt plant stems. Thus timing and placement are crucial. The herbicide prevents germination and emergence of weed seedlings, and also produces an antibiotic that protects crop seedlings from rotting.

8917. Cutler, H.G. (ed.). 1988. Biologically active natural products: potential use in agriculture.. ACS Symposium Series 380. American Chemical Society, Washginton, D.C. 483 pp..
This technical volume highlights the biochemistry of a number of potential compounds derived from microbes, plants, or insects, that may have a role as a pesticide or plant growth regulator. Topics include screening for microbial herbicides, the role of glucosinolates, compounds from sea organisms, and chitin/chitosan products.
