comprising semolina (a durum wheat flour), kaolin and peat moss. Connick, para.
bridging pp. 198-199. The dough is dried on a rack at room temperature and ground
into granules. Id., para. bridging pp. 199-200. Connick suggests that given the wheat

Quimby discloses a method of making an encapsulated biocontrol agent which is
resistant to water evaporation. Quimby, col. 1, lines 36-38. The method involves mixing
2
granules of biocontrol agents with a calcium salt solution to form calcium alginate
granules. Id., col. 2, lines 31-42. The granules are said to typically contain 0.7%-1.0%
sodium alginate and 4.5%-5.5% kaolin. Id., col. 2, lines 42-43. The granules are
thoroughly coated with an oil-in-water emulsion and an oil absorbent such as hydrated
silica, fumed silica, kaolin and other clays, corn bran, oat bran, wheat bran and other

2The granules are said to be made by mixing a sterile sodium alginate and kaolin
solution with a culture of the biocontrol agent(s). Quimby, col. 2, lines 31-39.
